Assessment of continuous pain in newborns admitted to NICUs in 18 European countries

The feasibility of a Swiss complex interprofessional intervention to improve the management of procedural pain in neonates in the Finnish context: A qualitative study

AIM

To evaluate the feasibility of the Swiss complex interprofessional intervention, NEODOL© (NEOnato DOLore), for improving the management of procedural pain in neonates in the Finnish context.

BACKGROUND

Interprofessional collaboration is important for all professionals involved in the care of neonates and for neonates' parents, to understand the appropriate use of non-pharmacological and/or pharmacological methods for each pain situation and how to assess pain in real-life situations. Appropriate methods of pain relief for neonates should be preferred as they protect the development of the neonate's brain.

DESIGN

A descriptive qualitative design.

METHOD

Data were collected through semi-structured focus group discussions following the Medical Research Council's framework for evaluation of complex interventions, in this case NEODOL© which aims to improve the procedural pain management of neonates. A purposive sample (n = 13) included eleven professionals representing various professions within Finnish Neonatal Intensive Care Units and two parents of infants who have received care in a Neonatal Intensive Care Unit. Data were analysed using inductive content analysis, and the results were reported in accordance with the COREQ guidelines.

RESULTS

Professionals' and parents' evaluations suggest that NEODOL© is feasible, because it is consistent and addresses a current need. They assessed its overall content to be relevant and accessible, and its components to be internally coherent. However, they emphasise the need for further evaluation and refinement of the intervention to achieve the desired outcomes and cost-effectiveness.

CONCLUSIONS

While NEODOL© is considered feasible, it requires further evaluation and refinement in the local context of each hospital before implementation.

Development of the neonatal pain response variable set: a mixed methods consensus process

While over 40 neonatal pain assessment scales have been published, owing to a lack of consensus and standardized metrics, there are more than 100 assessment indicators with varying descriptors and quality differences. This study aims to reach a consensus on optimal and comprehensive variables for neonatal pain assessment, leading to the development of a multidimensional neonatal pain response variable set. This study consisted of three phases: (1) A literature review was conducted to identify influencing factors and assessment indicators of neonatal pain response. (2) Panel meetings involving neonatal healthcare professionals evaluated and screened factors and indicators to develop an initial draft of the variable set. (3) Through two rounds of Delphi study achieved consensus, and determined the neonatal pain response variable set. Through a literature review and a panel meeting, the identified factors and indicators were categorized into contextual, physiological, and behavioral variables, forming an initial draft of the variable set. Sixteen professionals participated in two rounds of the Delphi study, with response rates exceeding 70%, and authority coefficients surpassing 0.7 in both rounds. The final iteration of the variable set includes 9 contextual variables, 2 physiological variables, and 5 behavioral variables.   Conclusion: Neonatal pain response variable set developed in this study is scientific, comprehensive, and multidimensional, aligning with the characteristics of neonatal pain response and clinically applicable. The inclusion of contextual variables enhances the ability to confront the complexity of clinical environments and individual differences. It can provide a practical and theoretical basis for clinical research on neonatal pain assessment. What is Known: • Neonatal pain assessment relies on scales used by healthcare professionals currently. But there is no "gold standard" for neonatal pain assessment. • While over 40 neonatal pain assessment scales have been published, owing to a lack of consensus and standardized metrics, there are more than 100 assessment indicators with varying descriptors and quality differences. Most of scales overlook the clinical environment complexity individual differences in pain responses, diminishing the accuracy and applicability. What is New: • In addition to the commonly used physiological and behavioral variables in the scales, we have incorporated contextual variables to better address the complexity of clinical environments and individual differences in pain responses. • Through an evidence-based approach, developed a neonatal pain response variable set comprising 9 contextual variables, 2 physiological variables, and 5 behavioral variables.

Nurses' Assessment of Pain in Saudi Neonatal Intensive Care Units

BACKGROUND

Research reveals that neonatal pain management in Neonatal Intensive Care Units (NICUs) is suboptimal. There is limited research that assessed NICU nurses' pain assessment practices in Saudi Arabia.

AIM

To assess the nurses' pain assessment practices in the NICU in Saudi Arabia.

DESIGN

This study used a descriptive cross-sectional design.

SETTINGS

Research was conducted using an online survey.

PARTICIPANTS/SUBJECTS

This study was carried out on 65 NICU nurses. The participants were recruited from one governmental and one private hospital in Saudi Arabia.

METHODS

Data on pain assessment practices were collected, including the frequency of pain assessment, pain assessment scales used for preterm and term neonates, and pain assessment documentation. Data were analyzed using frequencies and percentages.

RESULTS

The majority of the participants (94%) routinely assessed pain and documented pain assessment (97%). One-third of the participants assessed pain regularly every hour (32%). The most used pain assessment scales for term neonates were the neonatal infant pain scale (40%) and the cry, required oxygen, increased vital signs, expression, and sleeplessness scale (23%). The most used pain assessment scales for preterm neonates were the neonatal infant pain scale (31%), the cry, required oxygen, increased vital signs, expression, sleeplessness scale (19%), and the premature infant pain profile (17%).

CONCLUSIONS

NICU nurses in Saudi Arabia consistently assessed for and documented pain; however, the tools chosen were sometimes suboptimal. A substantial number of NICU nurses used invalid tools to assess pain in term and preterm neonates. An interventional program is needed to enhance the use of evidence-based practice recommendations regarding neonatal pain assessment by nurses in the Neonatal Intensive Care Units in Saudi Arabia.

Prolonged pain in premature neonates hospitalised in neonatal intensive care units: A scoping review

BACKGROUND

Exposure to repetitive pain during the neonatal period has been shown to have important short and long-term effects on the neurodevelopment of the premature neonate and can contribute to experienced prolonged pain. A uniform taxonomy of neonatal prolonged pain is still lacking to this day which contributes to suboptimal prolonged pain management in neonatal intensive care units. Accordingly, a scoping review exploring the state of knowledge about prolonged pain in preterm neonates hospitalised in the neonatal intensive care unit will contribute to the developing field of neonatal prolonged pain and provide recommendations for clinical prolonged pain management.

OBJECTIVE

To determine the scope, extent, and nature of the available literature on prolonged pain in premature neonates hospitalised in neonatal intensive care units.

DESIGN

Scoping review.

METHODS

An electronic search was conducted from inception to November 2023 in the databases of CINAHL, PubMed, Medline, Web of Science, GeryLit.org and Grey Source Index. Included studies discussed concepts related to neonatal prolonged pain such as definitions of prolonged pain, indicators of prolonged pain, contexts that result in prolonged pain, prolonged pain evaluation tools, consequences of prolonged pain and interventions for prolonged pain management.

RESULTS

Key concepts of neonatal prolonged pain were identified in the 86 included articles of this scoping review such as definitions (n = 26), indicators (n = 39), contexts (n = 49), scales (n = 56), consequences of prolonged pain (n = 30) and possible interventions for prolonged pain management (n = 22). Whilst a consensus on a definition has yet to be achieved, no proximate event was shown to cause prolonged pain and a time criterion was identified by authors as being relevant in defining prolonged pain. Interestingly, the context of hospitalisation was identified as being the most indicative of prolonged pain in premature neonates and should guide its evaluation and management, whilst only limited pain management interventions and consequences were discussed.

CONCLUSION

The findings of this scoping review contribute to the foundation of growing knowledge in neonatal prolonged pain and shed light on the ambiguity that currently exists on this topic in the scientific literature. This review summarises knowledge of key concepts necessary for a better understanding of prolonged pain and stresses the importance of considering contexts of hospitalisation for prolonged pain evaluation and management in neonatal intensive care units, with the objective of improving developmental outcomes of premature neonates.

TWEETABLE ABSTRACT

A scoping review reveals that the contexts of prolonged pain in premature neonates hospitalised in the neonatal intensive care unit are essential in guiding its evaluation and management.

Performance Evaluation of a Supervised Machine Learning Pain Classification Model Developed by Neonatal Nurses

BACKGROUND

Early-life pain is associated with adverse neurodevelopmental consequences; and current pain assessment practices are discontinuous, inconsistent, and highly dependent on nurses' availability. Furthermore, facial expressions in commonly used pain assessment tools are not associated with brain-based evidence of pain.

PURPOSE

To develop and validate a machine learning (ML) model to classify pain.

METHODS

In this retrospective validation study, using a human-centered design for Embedded Machine Learning Solutions approach and the Neonatal Facial Coding System (NFCS), 6 experienced neonatal intensive care unit (NICU) nurses labeled data from randomly assigned iCOPEvid (infant Classification Of Pain Expression video) sequences of 49 neonates undergoing heel lance. NFCS is the only observational pain assessment tool associated with brain-based evidence of pain. A standard 70% training and 30% testing split of the data was used to train and test several ML models. NICU nurses' interrater reliability was evaluated, and NICU nurses' area under the receiver operating characteristic curve (AUC) was compared with the ML models' AUC.

RESULTS

Nurses weighted mean interrater reliability was 68% (63%-79%) for NFCS tasks, 77.7% (74%-83%) for pain intensity, and 48.6% (15%-59%) for frame and 78.4% (64%-100%) for video pain classification, with AUC of 0.68. The best performing ML model had 97.7% precision, 98% accuracy, 98.5% recall, and AUC of 0.98.

IMPLICATIONS FOR PRACTICE AND RESEARCH

The pain classification ML model AUC far exceeded that of NICU nurses for identifying neonatal pain. These findings will inform the development of a continuous, unbiased, brain-based, nurse-in-the-loop Pain Recognition Automated Monitoring System (PRAMS) for neonates and infants.

Neonatal Intensive Care Nurses' Knowledge of Neonatal Pain Assessment in Private and Public Hospitals in Jeddah, Saudi Arabia: A Cross-Sectional Study

BACKGROUND

Neonatal Intensive Care Unit (NICU) nurses with adequate neonatal pain assessment knowledge are crucial in effective neonatal pain management. There is limited research that assessed the knowledge of NICU nurses in Saudi Arabia regarding neonatal pain assessment.

OBJECTIVE

To assess the knowledge of NICU nurses in Saudi Arabia regarding neonatal pain assessment.

DESIGN AND METHODS

 A cross-sectional design using an online survey was conducted to capture information regarding neonatal pain assessment knowledge from 125 NICU nurses in Saudi Arabia. Knowledge of pain assessment was assessed using a modified version of the knowledge, attitudes, and practice scale. Knowledge scores were classified as high, average, and low.

RESULTS

Participants' knowledge regarding neonatal pain assessment was inadequate (Mean = 63/100). The majority of the participants had a low to average level of knowledge (n= 97, 78%).

CONCLUSION

A significant proportion of NICU nurses had inadequate knowledge regarding neonatal pain assessment, which can be improved. Educational interventions are needed to boost these nurses' knowledge regarding neonatal pain assessment.

Pediatricians' focus of sight at pain assessment during a neonatal heel puncture

OBJECTIVE

To evaluate the focus of pediatricians' gaze during the heel prick of neonates.

METHODS

Prospective study in which pediatricians wearing eye tracker glasses evaluated neonatal pain before/after a heel prtick. Pediatricians scored the pain they perceived in the neonate in a verbal analogue numerical scale (0=no pain; 10=maximum pain). The outcomes measured were number and time of visual fixations in upper face, lower face, and hands, in two 10-second periods, before (pre) and after the puncture (post). These outcomes were compared between the periods, and according to pediatricians' pain perception: absent/mild (score: 0-5) and moderate/intense (score: 6-10).

RESULTS

24 pediatricians (31 years old, 92% female) evaluated 24 neonates. The median score attributed to neonatal pain during the heel prick was 7.0 (Interquartile range: 5-8). Compared to pre-, in the post-periods, more pediatricians fixed their gaze on the lower face (63 vs. 92%; p=0.036) and the number of visual fixations was greater on the lower face (2.0 vs. 5.0; p=0.018). There was no difference in the number and time of visual fixations according to the intensity of pain.

CONCLUSIONS

At bedside, pediatricians change their focus of attention on the neonatal face after a painful procedure, focusing mainly on the lower part of the face.

Parental Participation in Their Infants' Procedural Pain Alleviation with Nonpharmacologic Methods in Estonia

BACKGROUND

Aim: To describe parent's participation in their infants' procedural pain alleviation using nonpharmacologic methods in neonatal and neonatal intensive care units.

METHOD

A descriptive cross-sectional survey study was carried out in four Estonian hospitals between 2019 and 2020. Data were collected by using a validated questionnaire comprised of three sections: (1) background information of parents and infants; (2) nonpharmacologic methods used by parents; and (3) parental guidance by nurses on the methods. Altogether 280 questionnaires were distributed to parents and 232 of them were received back. Finally, 189 of them were included in the study (response rate 67.5%). The data were analyzed using descriptive and analytical statistics. Analysis of open-ended questions followed principles of inductive content analysis.

RESULTS

Most participants reported using nonpharmacologic methods, such as holding and placing the infant in a more comfortable position, nearly always/always (61%, 62%, respectively). However, rarely used methods included skin-to-skin contact (7%), breastfeeding the infant (7%), and listening to recorded music (3%). While studying a correlation between the parents' use of nonpharmacologic methods and their guidance, we found a correlation among all nonpharmacologic methods. However, almost half (48%) of the parents reported that the nurses advised them "sometimes" or "nearly always/ always" to go elsewhere during painful procedures rather than participating in alleviation of the infant´s pain.

CONCLUSIONS

The parents reported using mostly the nonpharmacologic methods that were easy to implement and did not require thorough instructions in preparation. In addition, it seemed that parents wanted to be more involved in their infant's pain alleviation, but they were advised not to take part in painful procedures and pain alleviation for various reasons. Therefore, more attention should be paid to the principles of family-centered care. As health care providers, we should welcome all families as team members to involve in their infants' pain alleviation in the neonatal and neonatal intensive care units.

Pharmacokinetics and safety of prolonged paracetamol treatment in neonates: An interventional cohort study

AIMS

To investigate the pharmacokinetics and safety of prolonged paracetamol use (>72 h) for neonatal pain.

METHODS

Neonates were included if they received paracetamol orally or intravenously for pain treatment. A total of 126 samples were collected. Alanine aminotransferase and bilirubin were measured as surrogate liver safety markers. Paracetamol and metabolites were measured in plasma. Pharmacokinetic parameters for the parent compound were estimated with a nonlinear mixed-effects model.

RESULTS

Forty-eight neonates were enrolled (38 received paracetamol for >72 h). Median gestational age was 38 weeks (range 25-42), and bodyweight at inclusion was 2954 g (range 713-4750). Neonates received 16 doses (range 4-55) over 4.1 days (range 1-13.8). The median (range) dose was 10.1 mg/kg (2.9-20.3). The median oxidative metabolite concentration was 14.6 μmol/L (range 0.12-113.5) and measurable >30 h after dose. There was no significant difference (P > .05) between alanine aminotransferase and bilirubin measures at <72 h or >72 h of paracetamol treatment or the start and end of the study. Volume of distribution and paracetamol clearance for a 2.81-kg neonate were 2.99 L (% residual standard error = 8, 95% confidence interval 2.44-3.55) and 0.497 L/h (% residual standard error = 7, 95% confidence interval 0.425-0.570), respectively. Median steady-state concentration from the parent model was 50.3 μmol/L (range 30.6-92.5), and the half-life was 3.55 h (range 2.41-5.65).

CONCLUSION

Our study did not provide evidence of paracetamol-induced liver injury nor changes in metabolism in prolonged paracetamol administration in neonates.

Evaluation of procedural pain for neonates in a neonatal intensive care unit: a single-centre study

BACKGROUND

To evaluate the procedural pain experienced by neonates in a neonatal intensive care unit (NICU) setting and determine the corresponding pain grades.

METHODS

Two experienced nurses independently used the Neonatal Infant Pain Scale (NIPS) to evaluate the neonatal pain during procedures taking place in the tertiary NICU and two level-two neonatal care units in the Children's Hospital of Zhejiang University School of Medicine. The mean and distribution of NIPS pain scores and the corresponding pain grades of participants when experiencing clinical painful procedures were analysed.

RESULTS

A total of 957 neonates exposed to 15 common clinical painful procedures were included in the study. The clinical painful procedures experienced by 957 participants could be divided into three groups: severe pain (NIPS score 5-7: peripheral intravenous cannulation, arterial catheterisation, arterial blood sampling, peripherally inserted central catheter placement and nasopharyngeal suctioning), mild to moderate pain (NIPS score 3-4: finger prick, intramuscular injection, adhesive removal, endotracheal intubation suctioning, heel prick, lumbar puncture and subcutaneous injection) and no pain to mild pain (NIPS score 0-2: gastric tube insertion, enema and intravenous injection).

CONCLUSIONS

The neonatal pain response to clinical procedures in NICU had certain pattern and preintervention drug analgesia could be taken for painful procedures with clustered high NIPS pain scores. Meanwhile, full coverage non-drug pain relief measures could be taken for procedures that are with scattered pain scores, and real-time pain evaluation should be provided to determine whether further drug analgesia is required.

Commentary: Pediatric Pain Measurement, Assessment, and Evaluation

PEDIATRIC PAIN MEASUREMENT, ASSESSMENT, AND EVALUATION

Renee C.B. Manworren, Jennifer Stinson Seminars in Pediatric Neurology Volume 23, Issue 3, August 2016, Pages 189-200 Assessment provides the foundation for diagnosis, selection of treatments, and evaluation of treatment effectiveness for pediatric patients with acute, recurrent, and chronic pain. Extensive research has resulted in the availability of a number of valid, reliable, and recommended tools for assessing children's pain. Yet, evidence suggests children's pain is still not optimally measured or treated. In this article, we provide an overview of pain evaluation for premature neonates to adolescents. The difference between pain assessment and measurement is highlighted; and the key steps to follow are identified. Information about self report and behavioral pain assessment tools appropriate for children are provided; and fac tors to be considered when choosing a specific 1 are outlined. Finally, we preview future approaches to personalized pain medicine in pediatrics that include harnessing the use of potential digital health technologies and genomics.

Organisational challenges of pain management in neonatal intensive care unit: a qualitative study

OBJECTIVES

Despite credible evidence, optimal neonates' pain management in the neonatal intensive care unit (NICU) is a challenging issue. In this regard, the organisational context is an essential factor. The existing challenges vary depending on the context, and investigating them can help to improve the quality of care. The study aimed to explore organisational challenges to neonates' pain management in the NICU.

METHODS

This qualitative study included 31 nurses and physicians in the NICU of Children's Hospital, Tabriz, Iran. Data collection was done through individual and focus group interviews. For data analysis, we used conventional content analysis.

RESULTS

The identified challenges included organisational culture (poor interprofessional collaboration and low parental participation), organisational structure (lack of unified approach in relieving pain and limited supervision for pain management) and organisational resources (lack of time due to high workload and inadequate educational programmes).

CONCLUSIONS

Many organisational factors consistently affect neonatal pain management. Adopting some approaches to enhance the cooperation of treatment team members, holding educational programmes, proper organisational supervision and implementing a unified neonatal-based pain management programme could improve neonatal pain management.

Non-pharmacological management of infant and young child procedural pain

BACKGROUND

Despite evidence of the long-term implications of unrelieved pain during infancy, it is evident that infant pain is still under-managed and unmanaged. Inadequately managed pain in infancy, a period of exponential development, can have implications across the lifespan. Therefore, a comprehensive and systematic review of pain management strategies is integral to appropriate infant pain management. This is an update of a previously published review update in the Cochrane Database of Systematic Reviews (2015, Issue 12) of the same title.

OBJECTIVES

To assess the efficacy and adverse events of non-pharmacological interventions for infant and child (aged up to three years) acute pain, excluding kangaroo care, sucrose, breastfeeding/breast milk, and music.

SEARCH METHODS

For this update, we searched CENTRAL, MEDLINE-Ovid platform, EMBASE-OVID platform, PsycINFO-OVID platform, CINAHL-EBSCO platform and trial registration websites (ClinicalTrials.gov; International Clinical Trials Registry Platform) (March 2015 to October 2020). An update search was completed in July 2022, but studies identified at this point were added to 'Awaiting classification' for a future update.  We also searched reference lists and contacted researchers via electronic list-serves.  We incorporated 76 new studies into the review.  SELECTION CRITERIA: Participants included infants from birth to three years in randomised controlled trials (RCTs) or cross-over RCTs that had a no-treatment control comparison. Studies were eligible for inclusion in the analysis if they compared a non-pharmacological pain management strategy to a no-treatment control group (15 different strategies). In addition, we also analysed studies when the unique effect of adding a non-pharmacological pain management strategy onto another pain management strategy could be assessed (i.e. additive effects on a sweet solution, non-nutritive sucking, or swaddling) (three strategies). The eligible control groups for these additive studies were sweet solution only, non-nutritive sucking only, or swaddling only, respectively. Finally, we qualitatively described six interventions that met the eligibility criteria for inclusion in the review, but not in the analysis.  DATA COLLECTION AND ANALYSIS: The outcomes assessed in the review were pain response (reactivity and regulation) and adverse events. The level of certainty in the evidence and risk of bias were based on the Cochrane risk of bias tool and the GRADE approach. We analysed the standardised mean difference (SMD) using the generic inverse variance method to determine effect sizes.  MAIN RESULTS: We included total of 138 studies (11,058 participants), which includes an additional 76 new studies for this update. Of these 138 studies, we analysed 115 (9048 participants) and described 23 (2010 participants) qualitatively. We described qualitatively studies that could not be meta-analysed due to being the only studies in their category or statistical reporting issues. We report the results of the 138 included studies here. An SMD effect size of 0.2 represents a small effect, 0.5 a moderate effect, and 0.8 a large effect. The thresholds for the I2 interpretation were established as follows: not important (0% to 40%); moderate heterogeneity (30% to 60%); substantial heterogeneity (50% to 90%); considerable heterogeneity (75% to 100%). The most commonly studied acute procedures were heel sticks (63 studies) and needlestick procedures for the purposes of vaccines/vitamins (35 studies). We judged most studies to have high risk of bias (103 out of 138), with the most common methodological concerns relating to blinding of personnel and outcome assessors. Pain responses were examined during two separate pain phases: pain reactivity (within the first 30 seconds after the acutely painful stimulus) and immediate pain regulation (after the first 30 seconds following the acutely painful stimulus). We report below the strategies with the strongest evidence base for each age group. In preterm born neonates, non-nutritive sucking may reduce pain reactivity (SMD -0.57, 95% confidence interval (CI) -1.03 to -0.11, moderate effect; I2 = 93%, considerable heterogeneity) and improve immediate pain regulation (SMD -0.61, 95% CI -0.95 to -0.27, moderate effect; I2 = 81%, considerable heterogeneity), based on very low-certainty evidence. Facilitated tucking may also reduce pain reactivity (SMD -1.01, 95% CI -1.44 to -0.58, large effect; I2 = 93%, considerable heterogeneity) and improve immediate pain regulation (SMD -0.59, 95% CI -0.92 to -0.26, moderate effect; I2 = 87%, considerable heterogeneity); however, this is also based on very low-certainty evidence. While swaddling likely does not reduce pain reactivity in preterm neonates (SMD -0.60, 95% CI -1.23 to 0.04, no effect; I2 = 91%, considerable heterogeneity), it has been shown to possibly improve immediate pain regulation (SMD -1.21, 95% CI -2.05 to -0.38, large effect; I2 = 89%, considerable heterogeneity), based on very low-certainty evidence. In full-term born neonates, non-nutritive sucking may reduce pain reactivity (SMD -1.13, 95% CI -1.57 to -0.68, large effect; I2 = 82%, considerable heterogeneity) and improve immediate pain regulation (SMD -1.49, 95% CI -2.20 to -0.78, large effect; I2 = 92%, considerable heterogeneity), based on very low-certainty evidence.  In full-term born older infants, structured parent involvement was the intervention most studied. Results showed that this intervention has little to no effect in reducing pain reactivity (SMD -0.18, 95% CI -0.40 to 0.03, no effect; I2 = 46%, moderate heterogeneity) or improving immediate pain regulation (SMD -0.09, 95% CI -0.40 to 0.21, no effect; I2 = 74%, substantial heterogeneity), based on low- to moderate-certainty evidence. Of these five interventions most studied, only two studies observed adverse events, specifically vomiting (one preterm neonate) and desaturation (one full-term neonate hospitalised in the NICU) following the non-nutritive sucking intervention. The presence of considerable heterogeneity limited our confidence in the findings for certain analyses, as did the preponderance of evidence of very low to low certainty based on GRADE judgements.

AUTHORS' CONCLUSIONS

Overall, non-nutritive sucking, facilitated tucking, and swaddling may reduce pain behaviours in preterm born neonates. Non-nutritive sucking may also reduce pain behaviours in full-term neonates. No interventions based on a substantial body of evidence showed promise in reducing pain behaviours in older infants. Most analyses were based on very low- or low-certainty grades of evidence and none were based on high-certainty evidence. Therefore, the lack of confidence in the evidence would require further research before we could draw a definitive conclusion.

Assessment and management of neonatal pain: a best practice implementation project

BACKGROUND AND AIMS

Neonates are exposed to varying degrees of pain during their hospitalization, which are going to have a profound impact on their lives. Interventions to alleviate neonatal pain are inadequate and inconsistent. The project aims to promote evidence-based practice (EBP) for the assessment and management of neonatal patients with acute pain and to evaluate the impact of these practices on neonatal pain in hospital.

METHODS

The current project was conducted in the neonatal department of a tertiary hospital in China. Five audit criteria were developed for baseline and follow-up audits. The project used the JBI PACES software and JBI's Getting Research into Practice audit and feedback tool to take evidence-based healthcare into practice. A total of 100 neonates with acute pain procedures were evaluated at baseline and follow-up audit.

RESULTS

The results showed a poor compliance of the five audit indicators in the baseline audit and a significantly improved compliance of the five audit indicators in the follow-up audit. Compared to the baseline audit, audit criterion 1 increased from 0% to 86.1%, audit criterion 2 increased from 36.1% to 82.5%, audit criterion 3 increased from 12% to 61%, audit criterion 4 increased from 0% to 66%, and audit criterion 5 increased from 6% at baseline to 71% in the follow-up audit.

CONCLUSION

The project found that EBP can help nursing staff effectively manage neonatal patients who are experiencing acute painful operations. Further studies are necessary to ensure the sustainability of the criteria in the project.

Current pain management practices for preterm infants with necrotizing enterocolitis: a European survey

BACKGROUND

Necrotizing enterocolitis (NEC) is a highly painful intestinal complication in preterm infants that requires adequate pain management to prevent short- and long-term effects of neonatal pain. There is a lack of international guidelines for pain management in NEC patients. Therefore, this study aims to describe current pain management for NEC patients in European neonatal intensive care units (NICUs).

METHODS

An online survey was designed and conducted to assess current practices in pain management for NEC patients in European NICUs. The survey was distributed via neonatal societies, digital platforms, and professional contacts.

RESULTS

Out of the 259 responding unique European NICUs from 36 countries, 61% had a standard protocol for analgesic therapy, 73% assessed pain during NEC, and 92% treated NEC patients with intravenous analgosedatives. There was strong heterogeneity in the used pain scales and initial analgesic therapy, which mainly included acetaminophen (70%), fentanyl (56%), and/or morphine (49%). A third of NICU representatives considered their pain assessment adequate, and half considered their analgesic therapy adequate for NEC patients.

CONCLUSIONS

Various pain scales and analgesics are used to treat NEC patients in European NICUs. Our results provide the first step towards an international guideline to improve pain management for NEC patients.

IMPACT

This study provides an overview of current pain management practices for infants with necrotizing enterocolitis (NEC) in European neonatal intensive care units. Choice of pain assessment tools, analgosedatives, and dosages vary considerably among NICUs and countries. A third of NICU representatives were satisfied with their current pain assessment practices and half of NICU representatives with their analgesic therapy practices in NEC patients in their NICU. The results of this survey may provide a first step towards developing a European pain management consensus guideline for patients with NEC.

[Evidence-based guideline for neonatal pain management in China (2023)]

Pain disrupts neonatal vital signs and internal environment homeostasis and affects the recovery process, and recurrent pain stimulation is one of the important risk factors for neurodevelopmental disorders and some chronic diseases. In order to standardize pain management practice in neonatal wards in China and effectively prevent and reduce the adverse effects of pain on the physical and mental development of neonates, National Clinical Research Center for Child Health and Diseases (Children's Hospital of Chongqing Medical University) convened a multidisciplinary panel to formulate the evidence-based guideline for neonatal pain management in China (2023 edition) following the principles and methods for the guideline development issued by the World Health Organization. Based on the best evidence and expert consensus, this guideline gives 26 recommendations for nine clinical issues, i.e., the classification and definition of neonatal pain, common sources of pain, pain assessment principles, pain assessment methods, analgesic principle, non-pharmaceutical analgesic methods, pharmaceutical analgesic methods, parental participation in pain management, and recording methods for pain management, so as to provide medical staff with guidance and a decision-making basis for neonatal pain assessment and analgesia management.

COMFORTneo scale: a reliable and valid instrument to measure prolonged pain in neonates?

OBJECTIVE

We studied the reliability and validity of the COMFORTneo scale, designed to measure neonatal prolonged pain.

STUDY DESIGN

This prospective observational study evaluated four clinimetric properties of the COMFORTneo scale from NICU nurses' assessments of neonates' pain. Intra-rater reliability was determined from three video fragments at two time points. Inter-rater reliability and construct validity were determined in five neonates per nurse with the COMFORTneo and numeric rating scales (NRS) for pain and distress. Pain scores using N-PASS were correlated with COMFORTneo scores to further evaluate construct validity.

RESULT

Intra-rater reliability: Twenty-two nurses assessed pain twice with an intraclass correlation coefficient (ICC) of 0.70. Inter-rater reliability: The ICC for 310 COMFORTneo scores together with 62 nurses was 0.93. Construct validity: Correlation between COMFORTneo and NRS pain, distress, and N-PASS was 0.34, 0.72, and 0.70, respectively.

CONCLUSION

The COMFORTneo can be used to reliably and validly assess pain in NICU patients.

Skin-to-skin contact-An effective intervention on pain and stress reduction in preterm infants

Introduction

The outcomes of pain and stress in preterm infants in the neonatal intensive care units (NICUs) compel the continued search for pain- and stress-reducing interventions.

The objective of the study

To investigate how skin-to-skin contact (SSC) influences chronic pain and stress in preterm infants in the NICU.

Materials and methods

The study included 140 preterm infants in the NICU with gestational age less than 34 weeks. The overall design was a baseline-response design. Urine and saliva were collected before (baseline) and after SSC to measure pain and stress markers by enzyme immunoassay method. The behavioral indicators of chronic pain were assessed using the EDIN (Échelle Douleur Inconfort Nouveau-Né-neonatal pain and discomfort).

Results

There was a significant decrease in the dopamine level in preterm infants after SSC in comparison with baseline values (85.99 [69.35; 112.20] pg/ml vs. 132.20 [104.80; 183.70] pg/ml), p < 0.001. The β-endorphin and serotonin levels increased after SSC (40.09 [26.81; 70.63] pg/ml vs. 29.87 [20.61; 46.94] pg/ml, p = 0.009 and 25.49 [20.45; 40.08] ng/ml vs. 22.30 [15.13; 31.65] ng/ml, p = 0.011, respectively). A significant decrease in cortisol levels in saliva and urine after SSC in comparison with baseline values (0.125 [0.079; 0.225] μg/dl vs. 0.371 [0.188; 1.002] μg/dl, p = 0.000 and 27.06 [14.59; 35.35] ng/ml vs. 35.25 [19.78; 61.94] ng/ml, p = 0.001, with a simultaneous increase of oxytocin level (57.00 [36.55; 88.49] pg/ml vs. 38.20 [28.78; 56.04] pg/ml, p = 0.009 were revealed. The total pain EDIN score in infants after SSC was below 6 points, significantly decreasing compared to the baseline (p < 0.05).

Conclusion

Preterm infants in the NICU experience stress and pain, which were confirmed by the EDIN pain scale and laboratory markers. The level of dopamine and cortisol as pain and stress hormones were reliably high, and normalized after regular SSC. Simultaneously, pain-relieving and anti-stress markers of oxytocin, β-endorphin and serotonin reliably increased in preterm infants in response to the SSC.

A Cross-Cultural Adaptation and Content Validity of COMFORTneo Scale into Brazilian Portuguese

CONTEXT

The instrument used to assess neonatal pain must be adequate regarding the type of pain, population, country, and language to provide the best evidence-based clinical strategies; however, few neonatal pain instruments have been translated and validated for the Brazilian population.

OBJECTIVE

The aim was to perform a cross-cultural adaptation of the COMFORTneo scale into Brazilian Portuguese and to evaluate the content validity of the adapted scale.

METHODS

The cross-cultural adaptation process followed six main steps: translation, synthesis of the translations, back-translation, submission to the expert committee, final version pretest, being that 65 individuals participated in this stage, including both healthcare professionals and students, and submission to the committee for process appraisal. Additionally, an equivalence form composed of a four-point Likert scale was sent to each committee participant to calculate the content validity index (CVI). The CVI was obtained as the sum of the items ranked as three or four by the experts divided by the total number of experts.

RESULTS

No difficulties were reported in the production of translated versions. The CVI for the final version of the translated instrument was 0.99. The final version was reviewed to correct any possible grammatical errors. The layout was modified as necessary, and instructions on scale scoring were added to facilitate the application, resulting in the COMFORTneo Brazil scale.

CONCLUSION

The COMFORTneo scale was properly and cross-culturally adapted into Brazilian Portuguese, reaching semantic, idiomatic, experimental, and conceptual equivalence with the original instrument, and a good CVI.

Existence and perceived application of pain management protocols in German neonatal intensive care units

We explored the existence and application of standard operating procedures (SOPs) for pain management (PM) in German neonatal intensive care units (NICUs), and identified the factors associated with their application in practice. This study was part of the Safety4NICU project, a cross-sectional survey conducted from 2015 to 2016. All 224 German NICUs were invited to participate, providing written consent from the head neonatologist and head nurse. We distributed questionnaires to the head neonatologist, the head nurse, and the NICU staff (physicians and nurses). We asked the head neonatologist whether written SOPs for PM existed, and we asked the staff whether these SOPs were applied in their daily routine. We received evaluable responses from 468 physicians and 1251 nurses from 76 NICUs. Of these 76 NICUs, the head neonatologists from 54 NICUs (71.1%) reported that written SOPs for PM exist. However, only 48.5% of the physicians and 53.7% of the nurses declared that these existing SOPs were also applied. We found various predictors for the existing SOPs as being applied, depending on the profession. For physicians, clinical training was important (OR: 2.482, p ≤ 0.05), while for nurses their working experience was a decisive predictor (OR: 1.265, p ≤ 0.05). For both, a high level of perceived cooperative norms between physicians and nurses increased the probability that SOPs for PM were applied, whereas a high bed turnover rate decreased that probability. According to the responses from head neonatologists, written SOPs for PM were common in German NICUs. However, if management strategies on pain existed, this did not mean that these were directly applied in the daily routine. Clinical training of the staff, the promotion of adequate interprofessional cooperation, as well as allowing time to deal with these SOPs might be all essential measures to strengthen the application.

Interprofessional Collaboration in the Context of Pain Management in Neonatal Intensive Care: A Cross-Sectional Survey

PURPOSE

Describe interprofessional collaboration (IPC) in the context of pain management in neonatal intensive care based on healthcare team members' perceptions of partnership, cooperation and coordination.

DESIGN

A descriptive cross-sectional study design was used.

BACKGROUND

IPC improves the quality of pain management for neonates. IPC is teamwork involving both professionals and the neonates' parents. Parents play an important role in the holistic care of their infant, which includes pain management.

METHODS

Data was collected with Assessment of Interprofessional Collaboration Scale (AITCS-II) from the healthcare teams featuring representatives (n = 132) of multiple professional groups who were working in neonatal intensive care units (n = 4) in Finland. Descriptive statistical methods and the Mann-Whitney or Kruskal-Wallis nonparametric tests were used to analyze the data.

RESULTS

The results were examined in three subscales of IPC (partnership, cooperation and coordination) on three different levels: "need to focus on developing collaborative practice", "moving towards collaboration" and "good collaboration". Participants perceived all the subscales as well as the overall level of IPC for pain management in neonatal intensive care to be at level "moving towards collaboration".

CONCLUSION

Participants appreciated each other as professionals and were willing to cooperate, but they had different perceptions of parental involvement in IPC. Attention should be paid to IPC in specific contexts such as pain management.

The Declaration of Lima on Pain in Childhood is a call into action to improve the care provided to children and adolescents with pain.

Assessment of salivary cortisol concentrations for procedural pain monitoring in newborns

OBJECTIVES

The study aimed to evaluate the usefulness of salivary cortisol (SC) for the assessment of procedural pain intensity in preterm and term newborns.

METHODS

Three groups of neonates (term, 37⁰-41⁶ weeks; moderate to late preterm, 32⁰-36⁶; and very preterm, <32⁰) hospitalized in neonatal intensive care unit were assessed for the study. Response to nappy change, lung ultrasound (LUS), and blood sampling was analyzed. The intensity of pain was evaluated using continuous heart rate and blood oxygen saturation (SpO₂) monitoring, Neonatal Infant Pain Scale (NIPS), and SC concentrations. Saliva samples were collected before and 20 min after the procedure's end.

RESULTS

Seventy-one infants were examined: 30 term, 21 moderate to late preterm, and 20 very preterm. SC has increased significantly in response to nappy change only in very preterm newborns (2.13 ng/mL [1.55-3.68] vs. 2.84 ng/mL [1.93-9.06], p = 0.01). LUS did not affect concentrations of SC in any group. Significant increase in SC was observed after blood sampling in term and very preterm infants (2.2 ng/mL [1.45-2.92] vs. 4.29 ng/mL [3.88-5.73], p = 0.002, and 1.88 ng/mL [1.47-4.13] vs. 5.3 ng/mL [3.42-8.02], p = 0.002, respectively). A significant correlation between values of SC increase and NIPS scores was found (Spearman's rank correlation coefficient [r_s] = 0.31, p = 0.001).

CONCLUSIONS

We observed the increase in SC concentrations in response to painful stimulus. The presence of a correlation between NIPS scores and SC increase suggests that SC can be used as an objective parameter to assess pain in neonates.

Artificial Intelligence Based Pain Assessment Technology in Clinical Application of Real-World Neonatal Blood Sampling

Background: Accurate neonatal pain assessment (NPA) is the key to neonatal pain management, yet it is a challenging task for medical staff. This study aimed to analyze the clinical practicability of the artificial intelligence based NPA (AI-NPA) tool for real-world blood sampling. Method: We performed a prospective study to analyze the consistency of the NPA results given by a self-developed automated NPA system and nurses’ on-site NPAs (OS-NPAs) for 232 newborns during blood sampling in neonatal wards, where the neonatal infant pain scale (NIPS) was used for evaluation. Spearman correlation analysis and the degree of agreement of the pain score and pain grade derived by the NIPS were applied for statistical analysis. Results: Taking the OS-NPA results as the gold standard, the accuracies of the NIPS pain score and pain grade given by the automated NPA system were 88.79% and 95.25%, with kappa values of 0.92 and 0.90 (p < 0.001), respectively. Conclusion: The results of the automated NPA system for real-world neonatal blood sampling are highly consistent with the results of the OS-NPA. Considering the great advantages of automated NPA systems in repeatability, efficiency, and cost, it is worth popularizing the AI technique in NPA for precise and efficient neonatal pain management.

The effectiveness of champions in implementing innovations in health care: a systematic review

BACKGROUND

Champions have been documented in the literature as an important strategy for implementation, yet their effectiveness has not been well synthesized in the health care literature. The aim of this systematic review was to determine whether champions, tested in isolation from other implementation strategies, are effective at improving innovation use or outcomes in health care.

METHODS

The JBI systematic review method guided this study. A peer-reviewed search strategy was applied to eight electronic databases to identify relevant articles. We included all published articles and unpublished theses and dissertations that used a quantitative study design to evaluate the effectiveness of champions in implementing innovations within health care settings. Two researchers independently completed study selection, data extraction, and quality appraisal. We used content analysis and vote counting to synthesize our data.

RESULTS

After screening 7566 records titles and abstracts and 2090 full text articles, we included 35 studies in our review. Most of the studies (71.4%) operationalized the champion strategy by the presence or absence of a champion. In a subset of seven studies, five studies found associations between exposure to champions and increased use of best practices, programs, or technological innovations at an organizational level. In other subsets, the evidence pertaining to use of champions and innovation use by patients or providers, or at improving outcomes was either mixed or scarce.

CONCLUSIONS

We identified a small body of literature reporting an association between use of champions and increased instrumental use of innovations by organizations. However, more research is needed to determine causal relationship between champions and innovation use and outcomes. Even though there are no reported adverse effects in using champions, opportunity costs may be associated with their use. Until more evidence becomes available about the effectiveness of champions at increasing innovation use and outcomes, the decision to deploy champions should consider the needs and resources of the organization and include an evaluation plan. To further our understanding of champions' effectiveness, future studies should (1) use experimental study designs in conjunction with process evaluations, (2) describe champions and their activities and (3) rigorously evaluate the effectiveness of champions' activities.

Nurses' Perception of Preterm Infants' Pain and the Factors of Their Pain Assessment and Management

In the neonatal intensive care unit, preterm infants undergo many painful procedures. Although these can impair their neurodevelopment if not properly managed, only half of the painful procedures are optimally handled. This cross-sectional study aimed to evaluate nurses' perceptions of preterm infants' pain, to evaluate nurses' pain assessment and management practices, as well as to identify the individual and contextual factors that influence nurses' assessments and interventions for pain management. Secondary analyses, including a mixed-model analysis, were performed with data from a larger study (n = 202 nurses). Nurses were found to have attitudes and perceptions in favor of preterm infants' pain management, although they reported using few standardized instruments to assess pain. Nurses stated that they widely used sucrose, non-nutritive sucking, and positioning as pain management interventions, while skin-to-skin contact was rarely practiced. Nurses' attitudes and perceptions influenced their pain assessment practices, which predicted their implementation of interventions. Several contextual (country, level of care, and work shift) and individual factors (age, level of education, had a preterm infant, perceptions of family-centered care, and skin-to-skin contact) also predicted nurses' pain assessment and management practices.

Evaluation of the Premature Infant Pain Profile-Revised (PIPP-R) e-Learning Module: Immediate and Sustained Competency

BACKGROUND

Electronic health (e-health) learning is a potential avenue to educate health professionals about accurately using infant pain assessment tools, although little is known about the impact of e-health interventions on clinical competence.

PURPOSE

To evaluate whether an e-health learning module for teaching the accurate use of the Premature Infant Pain Profile-Revised (PIPP-R) pain assessment tool results in immediate and sustained competency to assess infant pain.

METHODS

Neonatal intensive care unit (NICU) nurses who participated in a larger study across 2 tertiary NICUs in Canada examining the implementation and clinical utility of the PIPP-R e-learning module completed 2 follow-up evaluations at 1 week and 3 months. Participants were asked to view a video recording of an infant undergoing a painful procedure and to assess the infant's pain intensity response using the PIPP-R measure. Immediate and sustained competency was assessed via interrater consensus of participant-reported PIPP-R scores compared with those of an experienced trained coder.

RESULTS

Of the 25 eligible nurses, 22 completed 1-week and 3-month follow-up evaluations. At the 1-week follow-up, 84% of nurses scored the video accurately compared with 50% at 3 months. Behavioral pain indicators were more likely to be scored incorrectly than physiological indicators.

IMPLICATIONS FOR PRACTICE

Follow-up training after completion of the initial e-learning module training may improve competency related to the clinical use of the PIPP-R tool to assess infant pain over time.

IMPLICATIONS FOR RESEARCH

Additional study regarding the need and timing of e-health training to optimize sustained competency in infant pain assessment is warranted.

Improving pain management in a neonatal intensive care unit with single-family room-A quality improvement project

Preterm birth is a risk factor for early experience of pain. Despite advances in neonatal care, evidence-based knowledge of the importance of adequate pain management and strong international guidelines for assessment and treatment of neonatal pain, only 10% of sick term and preterm infants were assessed for pain and stress on a daily basis. The aim of this quality improvement (QI) project is evaluation of implemented guidelines for pain assessment and management, and increased parental involvement in a Norwegian single-family room NICU. Method: The different steps of the project entailed translation of the English version of COMFORTneo, development and implementation of guidelines with flowcharts for pain management, and pain assessment certification of the interprofessional staff. Part two of the project is supervision of the interprofessional staff in parental involvement in stress- and painful procedures. Our study showed that one year after implementation, 88.8% of the COMFORTneo assessments were performed according to the pain management guidelines. The staff used the flowcharts to assess, treat and reassess pain and stress. There was a high interrater reliability with linearly weighted Cohen's kappa values ranging from 0.81 to 0.95, with a median of 0.90. In addition, our study showed increased parental involvement in procedures, from 50.3% before to 82.3% after the quality improvement project. The success of this quality improvement project is explained by systematic use of flowcharts and implemented guidelines for pain management, interprofessional collaboration, and cultural change agents. Theoretical lectures and practical bedside supervision to interprofessional staff increased parental involvement in stress- and painful procedures.

Risk factors for prolonged mechanical ventilation in neonates following gastrointestinal surgery

Background

Prolonged mechanical ventilation (MV) should be avoided in neonates. Noninvasive ventilation (NIV) can facilitate weaning from MV but has risks for patients immediately following foregut surgery due to the potential risk of anastomotic leak. We evaluated the risk factors for prolonged MV following intestinal surgery in neonates.

Methods

We retrospectively reviewed 253 neonates undergoing intestinal surgery in 2017-2018 to identify risk factors for prolonged MV, and determine the correlation between NIV and anastomotic leak in a tertiary neonatal intensive care unit that performs the greatest number of neonatal surgeries in Ontario.

Results

The most common diagnoses were necrotizing enterocolitis/spontaneous intestinal perforation (NEC/SIP) 21%, intestinal atresia 16%, esophageal atresia/tracheoesophageal fistula 14%, ano-rectal malformation 13%, malrotation/volvulus 11%, gastroschisis 9% and omphalocele 4%. The median (IQR) duration of MV post-surgery was 3 (1-8) days with 25.7 % (n=65) of neonates on MV for >7 days. Compared to infants on MV post-surgery for ≤7 days, those with MV>7 days were of lower gestational age, birth weight and weight at surgery, but a higher proportion underwent stoma creation, had a longer duration of opioid administration and higher rates of moderate to severe bronchopulmonary dysplasia (BPD) and mortality (P<0.05). Generalized linear regression analysis showed lower gestational age (GA) and longer opioid administration were associated with longer duration of MV (P<0.001), but indication for surgery, weight at surgery and stoma creation didn't correlate with longer duration of MV (P>0.05). Of the 122 patients handled by one-stage resection with primary anastomosis, 22.1% (n=27) received NIV with 74.1% (n=20) commenced on NIV after 7 days post-surgery, anastomotic leak was detected in 2.5 % (3/122) patients and didn't correlate with NIV.

Conclusions

Lower GA and longer opioid administration were risk factors for prolonged MV in neonates following intestinal surgery. Further research is needed to investigate modifiable practices around pain assessment/ventilation in these patients, and the correlation between NIV and anastomotic leak.

Usefulness of two types of pain monitors in newborns treated in NICU, in the opinion of experts: Results of the survey

Pain experienced in the neonatal period has been shown to have serious short- and long-term consequences. It is also known that painkillers have side effects and should not be abused. The basis of proper pain management is assessment of pain, which in newborns is very difficult due to the lack of verbal communication. In these patients, behavioural scales are used to assess pain, but they have numerous shortcomings. For this reason, many newborns treated in the ICU are at risk of pain, so instrumental methods of detecting and assessing the severity of pain are being sought. During three months, seven Polish NICUs conducted research with the use of NIPE and SCA monitors. After this time, the heads of these departments filled in questionnaires regarding their individual opinions on the usefulness of these devices. All respondents found pain monitors useful in the NICU. The NIPE monitor was rated slightly higher, as its usefulness in assessing the effectiveness of analgosedation and in the management of patients in the postoperative period was better rated. The high acceptance of both devices by legal guardians of newborns is noteworthy. It should be stated that in newborns, any way to improve pain monitoring is valuable. In the opinion of Polish experts, pain monitors are useful in NICU. The NIPE monitor was assessed a little higher and was considered useful in the assessment of analgosedation and in postoperative treatment. Pain monitors can provide valuable support for pain assessment in newborns treated in the NICU.

Agreement of the Neonatal Pain, Agitation, and Sedation Scale (N-PASS) With NICU Nurses' Assessments

BACKGROUND

Objective assessment tools should standardize and reflect nurses' expert assessments. The Neonatal Pain, Agitation, and Sedation Scale (N-PASS) and the Neonatal Infant Pain Scale (NIPS) are valid measures of pain. The N-PASS also provides a sedation subscale.

PURPOSE

The objective of this study was to determine N-PASS clinical validity and utility by evaluating agreement of N-PASS scores with bedside nurses' assessments of pain/agitation and sedation in a 64-bed tertiary neonatal intensive care unit.

METHODS

Fifteen bedside nurses trained to use the N-PASS and the NIPS prospectively completed 202 pain/agitation and sedation assessments from a convenience sample of 88 infants, including chronically ventilated, medically fragile infants. N-PASS and NIPS scores were obtained simultaneously but independently of nurse investigators. Bedside nurses also made recommendations about infants' pain and sedation management.

RESULTS

There was moderate agreement between N-PASS pain scores and nurses' recommendations (κ= 0.52), very strong agreement between N-PASS sedation scores and nurses' recommendations (κ= 0.99), and very strong associations between N-PASS pain and NIPS scores (P< .001). Bedside nurse and independent investigator interrater reliability was good for N-PASS pain and NIPS scores (intraclass correlation coefficient [ICC] = 0.83, ICC = 0.85) and excellent for N-PASS sedation (ICC = 0.94). During 93% of assessments, bedside nurses reported that the N-PASS reflected the level of infant sedation well or very well.

IMPLICATIONS FOR PRACTICE AND RESEARCH

The N-PASS provides an easy-to-use, valid, and reliable objective measure of pain and sedation that reflects nurses' assessments. Additional studies using the N-PASS are needed to verify results and the influence of the N-PASS on pain and sedation management for medically fragile infants with chronic medical conditions.

Assessing Neonatal Pain with NIPS and COMFORT-B: Evaluation of NICU’s Staff Competences

Background

Pain is considered “the 5th vital sign” that should be regularly assessed in the neonatal intensive care setting. Although over 40 pain assessment tools have been developed for neonates, their implementation in everyday practice is challenging. Epidemiological studies demonstrate that pain is still underassessed and undertreated in European NICUs.

Purpose

To evaluate the interrater and intrarater reliability of the NIPS and COMFORT-B scales among the tertiary NICU's staff members 4 years after their implementation in local pain guidelines with no prior dedicated training.

Methods

Physicians and nurses were invited to evaluate 5 video recordings of infants hospitalized in the intensive care settings, using the NIPS and COMFORT-B scales. The assessment took part twice at a 3-month interval. Interrater reliability was calculated for both scales using Kendall's W coefficient of concordance and Krippendorff's alpha coefficient. Cohen's kappa was used to assess intrarater reliability.

Results

17 physicians and 19 nurses took part in the study. Interrater agreement for the COMFORT-B scale was above 0.8 for Kendall's W coefficient (p < .01) and above 0.667 for Krippendorff's alpha coefficient. Kendall's W coefficient for the NIPS scores ranged between 0.7 and 0.8 (p < .01). Krippendorff's alpha was above 0.667. Intrarater agreement for both the COMFORT-B and NIPS scales was 0.693 and 0.724, respectively.

Conclusions

Overall, the agreement between our staff members was moderately good for both scales. This is not enough to avoid inadequate pain assessment. More training is needed to improve NICU's staff competences in using pain scales.

What is the definition of acute episodic and chronic pain in critically ill neonates and infants? A global, four-stage consensus and validation study

OBJECTIVES

To define and validate types of pain in critically ill neonates and infants by researchers and clinicians working in the neonatal intensive care unit (NICU) and high dependency unit (HDU).

DESIGN

A qualitative descriptive mixed-methods design.

PROCEDURE/S

Each stage of the study was built on and confirmed the previous stages. Stage 1 was an expert panel to develop definitions; stage 2 was a different expert panel made up of neonatal clinicians to propose clinical characteristics associated with the definitions from stage 1; stage 3 was a focus group of neonatal clinicians to provide clinical case scenarios associated with each definition and clinical characteristics; and stage 4 was a survey administered to neonatal clinicians internationally to test the validity of the definitions using the clinical case scenarios.

RESULTS

In stage 1, the panel (n=10) developed consensus definitions for acute episodic pain and chronic pain in neonates and infants. In stage 2, a panel (n=8) established clinical characteristics that may be associated with each definition. In stage 3, a focus group (n=11) created clinical case scenarios of neonates and infants with acute episodic pain, chronic pain and no pain using the definitions and clinical characteristics. In stage 4, the survey (n=182) revealed that the definitions allowed an excellent level of discrimination between case scenarios that described neonates and infants with acute episodic pain and chronic pain (area under the receiver operating characteristic=0.87 and 0.89, respectively).

CONCLUSIONS

This four-stage study enabled the development of consensus-based and clinically valid definitions of acute episodic pain and chronic pain. There is a need to define and validate other pain types to inform a taxonomy of pain experienced by neonates and infants in the NICU and HDU.

Assessment and Management of Pain in Preterm Infants: A Practice Update

Infants born preterm are at a high risk for repeated pain exposure in early life. Despite valid tools to assess pain in non-verbal infants and effective interventions to reduce pain associated with medical procedures required as part of their care, many infants receive little to no pain-relieving interventions. Moreover, parents remain significantly underutilized in provision of pain-relieving interventions, despite the known benefit of their involvement. This narrative review provides an overview of the consequences of early exposure to untreated pain in preterm infants, recommendations for a standardized approach to pain assessment in preterm infants, effectiveness of non-pharmacologic and pharmacologic pain-relieving interventions, and suggestions for greater active engagement of parents in the pain care for their preterm infant.

Neonatal pain assessment: Do we have the right tools?

BACKGROUND

The assessment and management of neonatal pain is crucial for the development and wellbeing of vulnerable infants. Specifically, neonatal pain is associated with adverse health outcomes but is often under-identified and therefore under-treated. Neonatal stress may be misinterpreted as pain and may therefore be treated inappropriately. The assessment of neonatal pain is complicated by the non-verbal status of patients, age-dependent variation in pain responses, limited education on identifying pain in premature infants, and the clinical utility of existing tools.

OBJECTIVE

We review research surrounding neonatal pain assessment scales currently in use to assess neonatal pain in the neonatal intensive care unit.

METHODS

We performed a systematic review of original research using PRISMA guidelines for literature published between 2016 and 2021 using the key words "neonatal pain assessment" in the databases Web of Science, PubMed, and CINAHL. Fifteen articles remained after review, duplicate, irrelevant, or low-quality articles were eliminated.

RESULTS

We found research evaluating 13 neonatal pain scales. Important measurement categories include behavioral parameters, physiological parameters, continuous pain, acute pain, chronic pain, and the ability to distinguish between pain and stress. Provider education, inter-rater reliability and ease of use are important factors that contribute to an assessment tool's success. Each scale studied had strengths and limitations that aided or hindered its use for measuring neonatal pain in the neonatal intensive care unit, but no scale excelled in all areas identified as important for reliably identifying and measuring pain in this vulnerable population.

CONCLUSION

A more comprehensive neonatal pain assessment tool and more provider education on differences in pain signals in premature neonates may be needed to increase the clinical utility of pain scales that address the different aspects of neonatal pain.

Pain Behavioural Response to Acoustic and Light Environmental Changes in Very Preterm Infants

Noise and high light illumination in the neonatal intensive care unit (NICU) are recognized as stressors that could alter the well-being and development of vulnerable preterm infants. This prospective observational study evaluated the pain behaviours of very preterm infants (VPIs) to sound peaks (SPs) and light levels variations (LLVs) in the NICU. We measured spontaneously occurring SPs and LLVs in the incubators of 26 VPIs over 10 h. Their behavioural responses were analysed through video recordings using the "Douleur Aigue du Nouveau-né" (DAN) scale. We compared the maximum DAN scores before and after environmental stimuli and the percentage of VPIs with a score ≥ 3 according to the type of stimuli. A total of 591 SPs and 278 LLVs were analysed. SPs of 5 to 15 dBA and LLVs significantly increased the maximum DAN scores compared to baseline. The occurrence of DAN scores ≥ 3 increased with both stressors, with a total of 16% of SPs and 8% of LLVs leading to quantifiable pain behaviour. Altogether, this study shows that VPIs are sensitive to SPs and LLVs, with a slighter higher sensitivity to SPs. The mechanisms leading to pain behaviours induced by noise and light changes should be evaluated further in the context of VPIs brain development. Our results provide further arguments to optimize the NICU sensory environment of neonatal units and to adapt it to the expectations and sensory abilities of VPIs.

Available Instruments to Assess Pain in Infants

Pain assessment in newborns and infants is challenging for clinicians. Although behavioral and behavioral-physiological scales are validated pain assessment instruments, their use in this age group has significant limitations. In this review, we summarize the methods currently available for assessing pain in neonates and infants. It is possible that these pain detection methods are also useful for assessing the quality of anesthesia and analgosedation in these populations. Further research should be aimed at confirming the usefulness of these tools in infants and identifying additional pain assessment options for clinical practice.

[Item Reduction to Improve Practicability of Neonatal Pain Assessment Tools - Comparison of NFCSshort and PIPP in Daily Clinical Practice]

HINTERGRUND

Trotz über 50 psychometrisch validierter Beobachtungsverfahren gibt es bisher keinen Konsens über das praktikabelste Schmerzassessment bei Neugeborenen. Die Items von NFCSshort und PIPP wurden mit der Schmerzeinschätzung der prozedurbeteiligten Behandler verglichen und es wurde evaluiert, ob eine Itemreduktion zu Gunsten der Alltagsanwendung möglich wäre.

MATERIAL UND METHODEN

52 Neugeborene wurden in unserer Beobachtungsstudie einer klinisch indizierten peripheren Venenpunktion unterzogen. Patient und Monitordaten wurden standardisiert auf Video aufgezeichnet. Die Schmerzintensität wurden durch sieben unabhängige Untersucher mittels NFCSshort und PIPP bewertet und hinsichtlich der Variabilität zwischen den Untersuchern verglichen.

ERGEBNISSE

Nur vier Items des PIPP (Herzfrequenz, Augenbrauenvorwölbung, zusammengekniffene Augen, betonte Nasolabialfalte) wiesen einen signifikanten Zusammenhang mit der geschätzten Schmerzhaftigkeit der Prozedur auf. Die Items 1 (Gestationsalter), 2 (Wachheitsgrad) und 4 (Sauerstoffsättigung) hatten bei keinem Untersucher Einfluss auf das Schmerzmessergebnis. Die Auswertung des NFCSshort zeigte bei zwei Untersuchern für das Item 1 (Vorwölbung der Augenbrauen) und bei einem Untersucher für das Item 2 (zusammengekniffene Augen) keine Einflüsse auf das Messergebnis.

DISKUSSION

Die Ergebnisse der Studie legen eine Kürzung des PIPP um drei Items nahe, da diese keinen Einfluss auf das Schmerzmessergebnis zeigten. Eine Reduktion des PIPP um das Item Gestationsalter erscheint fraglich, da es in weiteren Studien als bedeutsames Item bewertet wurde. Ein Verzicht auf das Item Sauerstoffsättigung geht mit einem geringeren Messaufwand einher. Eine weitere Kürzung der bereits gekürzten Version (NFCSshort) auf weniger als fünf Items ist auf Basis unserer Ergebnisse nicht zu empfehlen.

BACKGROUND

Despite more than 50 laboratory-evaluated measurement systems, there is no consensus on the most practicable pain assessment in newborns in daily practice. For this purpose, the items of NFCSshort and PIPP were compared to the pain assesment of the involved medical practitioner. The aim of the study was to evaluate whether an item reduction of the assesments in favor of everyday use is feasible.

METHODS

In 52 neonates of a paediatric ward venous blood collection was performed in this observational study. Cameras recorded patients and monitor in a standardized way. The pain intensity was assessed with NFCSshort and PIPP by seven independent observers. The ratings were compared for variability between observers.

RESULTS

Of the seven PIPP items, only four were significantly associated with procedural pain assessment for all seven observers (heart rate, brow bulge, eye squeeze, nasolabial furrow). For the NFCSshort, no significant association with procedural pain assessment was found for two observers for the item "brow bulge" and for one observer for the item "eye squeeze".

CONCLUSION

The results of the study suggest a possible reduction of the PIPP by three items. Disregarding item 1 (gestational age) appears questionable, since its impact as context variable has been proven repeatedly. The waiver of item 4 (oxygen saturation) is associated with less measuring effort. A further reduction of the already shortened version of the NFCS with ten items (NFCSshort, five items) is not recommended by our results.

Staff awareness and bundling reduce skin breaks and blood tests in neonatal intensive care

AIM

Skin breaks (SBs) for procedures and blood sampling are common in neonatal intensive care units (NICU), contributing to pain, infection risk and anaemia. We aimed to document their prevalence, identify areas for improvement and, through staff awareness, reduce their frequency.

METHODS

Quality improvement project via prospective audit at a tertiary-level NICU in Australia was conducted. All infants admitted to the NICU for >24 h during two audit periods were included in the study. A specifically designed bedside audit tool was used to prospectively document all SB and blood tests performed on infants during a 4-week audit period (audit 1). Results were reviewed to identify areas for improvement, and disseminated to staff at unit meetings, shift handover and email. Following education and awareness, the audit was repeated (audit 2), and data were compared. Frequency of SB and blood tests performed was measured. Data were tested for normality and analysed using parametric or non-parametric tests where appropriate.

RESULTS

There were 52 NICU admissions during each audit period (104 total), with 34 (65%) and 31 (60%) having audit sheets completed, respectively. Median (interquartile range) gestational age and mean (standard deviation) birthweight were 29 (26.3-35) weeks and 1836 (1185) g for audit 1, 30 (28.5-31.5) weeks and 1523 (913) g for audit 2. The reduction in total blood tests (mean) was 36.3%, skin breaks per admitted baby day reduced by 60% and total blood volume sampled (mean) by 37.7%.

CONCLUSIONS

A quality improvement project by prospective audit and staff education was associated with reductions in frequency of skin breaks and blood tests in the NICU.

Identification of pain in neonates: the adults' visual perception of neonatal facial features

OBJECTIVE

To verify the visual attention of adults when assessing neonatal pain.

STUDY DESIGN

143 adults (59% health professionals) evaluated 20 pictures (2 pictures of 10 neonates' faces: at rest; during a painful procedure). Tobii-TX300 tracked the participants' eyes movement. For each picture, adults scored pain intensity (0 = no pain; 10 = maximum). Latent classes analysis was applied by cognitive diagnosis models-GDINA with two attributes (knowledge of pain presence/absence). Variables associated with belonging to the class of adults that correctly identified pictures of newborns with/without pain were identified by logistic regression.

RESULTS

To identify neonatal pain, adults look at the mouth, eyes, and forehead in facial pictures. The latent class analysis identified four classes of adults: those that identify painful/painless neonates (YY-Class; n = 80); only painful neonates (n = 28); only painless neonates (n = 34) and none (n = 1). Being a health professional (OR: 2.29; 95% CI: 1.16-4.51), and each look at the nasolabial furrow (2.07; 1.19-3.62) increased the chance of belonging to the YY-class.

CONCLUSIONS

Being a health professional and the visual fixation at the nasolabial furrow helped to identify the presence/absence of neonatal pain.

New perspective for pain control in neonates: a comparative effectiveness research

OBJECTIVE

To compare sucrose 24% oral gel formulation to liquid formula and breastfeeding during a heel prick in neonates.

STUDY DESIGN

In this comparative effectiveness research 195 neonates >36 weeks' gestation were randomised to three groups, receiving during heel stick: (i) breastfeeding, (ii) sucrose 24% liquid with non-nutritive sucking and (iii) sucrose 24% gel with non-nutritive sucking. The pain was assessed through the Neonatal Infant Pain Scale.

RESULTS

All the methods analysed has shown to be effective in reducing pain. There was an increase in odds of pain following liquid sucrose compared to breastfeeding (OR = 1.60; 95% CI: 0.82-3.3; p = 0.17). A reduction of odds of pain was showed comparing sucrose to breastfeeding (OR = 0.78; 0.38-1.6; 0.48), and comparing sucrose gel to liquid formula (OR = 0.48; 0.23-0.96; p = 0.04).

CONCLUSION

Sucrose 24% gel with non-nutritive sucking seems to be a valid alternative when breastfeeding is not possible. Further research is needed.

Newborn Infant Parasympathetic Evaluation Index for the Assessment of Procedural Pain in Nonanesthetized Infants: A Multicenter Pilot Study

OBJECTIVE

The aim of this study is to evaluate the ability of the Newborn Infant Parasympathetic Evaluation (NIPE) index to detect the response to nociceptive stimuli in nonanesthetized infants and to compare these results to simultaneous scoring by behavioral scales.

STUDY DESIGN

Thirty-six nonanesthetized infants admitted to neonatal/pediatric intensive care unit (N/PICUs) were enrolled to the study. Due to faulty records of the data, three patients had to be excluded. To detect pain caused by noxious stimuli, the heart-rate-variability-derived NIPE index and behavioral pain scales designed for measuring procedural pain in nonverbal children were used.

RESULTS

Forty-one painful events were available for analysis. We observed in the whole group a statistically significant decrease in NIPE values at 1, 2, and 3 minutes after a painful stimulus, in comparison to the NIPE value at rest and the statistically significant differences between the minimum NIPE value within 3 minutes after the stimulus in comparison to NIPE value at rest in the whole group, as well as in the subgroups of moderate and severe pain. Receiver operating characteristic (ROC) analysis has shown the strong sensitivity and specificity of the NIPE in detecting the noxious stimuli (ROC AUC: 0.767). We also found that the stronger the sensation of pain was, the more rapidly NIPE reached its lowest value.

DISCUSSION

Our study indicates that the painful procedures are associated with a significant decrease in the NIPE value within 3 minutes after a noxious stimulus. Based on our observation, the minimum value within 3 minutes from the painful procedure seems to be the most distinctive value.

Nurses' perception, knowledge, and use of neonatal pain assessment

Preterm and sick newborn infants undergo several painful procedures during their hospital stay, potentially leading to short‐ and long‐term negative consequences. Pain assessment should be performed regularly to provide optimal pain management. Nurses' knowledge of and attitude toward neonatal pain assessment affect how pain is assessed and managed in the clinical situation. The aim of this study was to explore Swedish nurses' perception, knowledge, and use of neonatal pain assessment. This descriptive, cross‐sectional questionnaire study was conducted across all Swedish neonatal units (n = 38). Respondents were chosen through convenience sampling by the head nurses at each unit. Ten nurses from each unit were asked to complete the survey, which contained both closed and open questions. A majority of the units (30/38; 79%) participated and 232 surveys were returned, a response rate of 61%. Of the nurses, 91% thought that neonatal pain assessment was important. Many nurses mentioned various difficulties with pain assessment and concerns that the scales used might not assess pain correctly. About half of the nurses considered themselves to have enough knowledge of neonatal pain assessment. Those who reported having enough knowledge of pain assessment viewed the pain scales used at their units more positively. Of the nurses, 74% reported using a pain assessment scale several times per work shift. Pain management guidelines were available according to 75% of nurses, but only 53% reported that the guidelines were followed. Although nurses in general expressed a positive attitude toward pain assessment scales, this was not necessarily evident in their clinical practice. Lack of knowledge, available or accessible guidelines, or concerns regarding the validity of available pain scales seemed to limit their use.

Opioids for newborn infants receiving mechanical ventilation

BACKGROUND

Mechanical ventilation is a potentially painful and discomforting intervention that is widely used in neonatal intensive care. Newborn infants demonstrate increased sensitivity to pain, which may affect clinical and neurodevelopmental outcomes. The use of drugs that reduce pain might be important in improving survival and neurodevelopmental outcomes.

OBJECTIVES

To determine the benefits and harms of opioid analgesics for neonates (term or preterm) receiving mechanical ventilation compared to placebo or no drug, other opioids, or other analgesics or sedatives.

SEARCH METHODS

We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2020, Issue 9), in the Cochrane Library; MEDLINE via PubMed (1966 to 29 September 2020); Embase (1980 to 29 September 2020); and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to 29 September 2020). We searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials comparing opioids to placebo or no drug, to other opioids, or to other analgesics or sedatives in newborn infants on mechanical ventilation. We excluded cross-over trials. We included term (≥ 37 weeks' gestational age) and preterm (< 37 weeks' gestational age) newborn infants on mechanical ventilation. We included any duration of drug treatment and any dosage given continuously or as bolus; we excluded studies that gave opioids to ventilated infants for procedures.

DATA COLLECTION AND ANALYSIS

For each of the included trials, we independently extracted data (e.g. number of participants, birth weight, gestational age, types of opioids) using Cochrane Effective Practice and Organisation of Care Group (EPOC) criteria and assessed the risk of bias (e.g. adequacy of randomisation, blinding, completeness of follow-up). We evaluated treatment effects using a fixed-effect model with risk ratio (RR) for categorical data and mean difference (MD) for continuous data. We used the GRADE approach to assess the certainty of evidence.

MAIN RESULTS

We included 23 studies (enrolling 2023 infants) published between 1992 and 2019. Fifteen studies (1632 infants) compared the use of morphine or fentanyl versus placebo or no intervention. Four studies included both term and preterm infants, and one study only term infants; all other studies included only preterm infants, with five studies including only very preterm infants. We are uncertain whether opioids have an effect on the Premature Infant Pain Profile (PIPP) Scale in the first 12 hours after infusion (MD -5.74, 95% confidence interval (CI) -6.88 to -4.59; 50 participants, 2 studies) and between 12 and 48 hours after infusion (MD -0.98, 95% CI -1.35 to -0.61; 963 participants, 3 studies) because of limitations in study design, high heterogeneity (inconsistency), and imprecision of estimates (very low-certainty evidence - GRADE). The use of morphine or fentanyl probably has little or no effect in reducing duration of mechanical ventilation (MD 0.23 days, 95% CI -0.38 to 0.83; 1259 participants, 7 studies; moderate-certainty evidence because of unclear risk of bias in most studies) and neonatal mortality (RR 1.12, 95% CI 0.80 to 1.55; 1189 participants, 5 studies; moderate-certainty evidence because of imprecision of estimates). We are uncertain whether opioids have an effect on neurodevelopmental outcomes at 18 to 24 months (RR 2.00, 95% CI 0.39 to 10.29; 78 participants, 1 study; very low-certainty evidence because of serious imprecision of the estimates and indirectness). Limited data were available for the other comparisons (i.e. two studies (54 infants) on morphine versus midazolam, three (222 infants) on morphine versus fentanyl, and one each on morphine versus diamorphine (88 infants), morphine versus remifentanil (20 infants), fentanyl versus sufentanil (20 infants), and fentanyl versus remifentanil (24 infants)). For these comparisons, no meta-analysis was conducted because outcomes were reported by one study.

AUTHORS' CONCLUSIONS

We are uncertain whether opioids have an effect on pain and neurodevelopmental outcomes at 18 to 24 months; the use of morphine or fentanyl probably has little or no effect in reducing the duration of mechanical ventilation and neonatal mortality. Data on the other comparisons planned in this review (opioids versus analgesics; opioids versus other opioids) are extremely limited and do not allow any conclusions. In the absence of firm evidence to support a routine policy, opioids should be used selectively - based on clinical judgement and evaluation of pain indicators - although pain measurement in newborns has limitations.

Neonates as intrinsically worthy recipients of pain management in neonatal intensive care

One barrier to optimal pain management in the neonatal intensive care unit (NICU) is how the healthcare community perceives, and therefore manages, neonatal pain. In this paper, we emphasise that healthcare professionals not only have a professional obligation to care for neonates in the NICU, but that these patients are intrinsically worthy of care. We discuss the conditions that make neonates worthy recipients of pain management by highlighting how neonates are (1) vulnerable to pain and harm, and (2) completely dependent on others for pain management. We argue for a relational account of ethical decision-making in the NICU by demonstrating how an increase in vulnerability and dependence may be experienced by the healthcare community and the neonate's family. Finally, an ethical framework for decisions around neonatal pain management is proposed, focussing on surrogate decision-making and the importance of compassionate action through both a reflective and an affective empathy. As empathy can be highly motivating against pain, we propose that, in addition to educational programs that raise awareness and knowledge of neonatal pain and pain management, healthcare professionals must cultivate empathy in a collective manner, where all members of the NICU team, including parents, are compassionate decision-makers.

Procedural Pain Assessment in Infants Without Analgosedation: Comparison of Newborn Infant Parasympathetic Evaluation and Skin Conductance Activity - A Pilot Study

Objective: New technologies to measure pain responses, such as heart rate variability and skin conductance hold promise in the development of tools that can be reliable and quantifiable of detecting pain. The main objective of this study was to assess the capability of two monitors i.e., Newborn Infant Parasympathetic Evaluation (NIPE) and Skin Conductance Algesimeter for detecting procedural pain in non-anesthetized infants. Materials and Methods: Thirty-three non-anesthetized infants were enrolled to the study. To detect pain caused by heel stick, NIPE, and Skin Conductance monitors and behavioral pain scales were used. Three minutes before and just after heel stick, pain was evaluated by behavioral scales, and simultaneously over the whole period by NIPE and SCA. Results: A statistically significant decrease of NIPE Index and an increase of SCA values were found after the HS procedure. There were no statistically significant differences between the decrease in NIPEi values and the increase in PPS values between subgroups based on pain assessment by behavioral-scale scores. Conclusion: Both NIPE and SCA can be useful for detection of procedural pain and may constitue an additional valuable tool for better handling of pain among patients treated in NICUs. More studies on larger groups of patients are needed.

Changes in Physicians' Perceptions and Practices on Neonatal Pain Management Over the Past 20 Years. A Survey Conducted at Two Time-Points

Intense research for more than three decades expelled the view that neonates do not experience pain. The aim of this survey was to investigate whether the Greek physicians involved in neonatal intensive care have changed their perceptions regarding neonatal pain, adapting their management practices to the knowledge that have emerged in the past 20-years. This study is a survey conducted at two time-points, 20 years apart. Anonymous questionnaires were distributed to 117 and 145 physicians working in neonatal intensive care units (NICUs) all over Greece in years 2000 and 2019, respectively. The response rate was 90.6 and 80.7% in 2000 and 2019, respectively. All respondents, at both time-points, believed that neonates experience pain, which has serious acute and long-term consequences, while the vast majority considered analgesia-sedation (A-S) during painful interventions as obligatory. Utilization of NICU protocols and pain assessment tools remained low although increased significantly between 2000 and 2019. The use of systemic A-S postoperatively was high at both time-points, while its implementation in infants subjected to prolonged pain, specifically mechanical ventilation, increased significantly by 2019. Systemic or local analgesia for acute procedural pain was used by lower proportions of physicians in 2019, except for the tracheal intubation. In contrast, the use of sweet solutions and non-pharmacological measures prior to or during bedside procedures significantly increased over time. Opioid administration significantly increased, while a shift from morphine to fentanyl was observed. International literature and perinatal-neonatal congresses were stated as the main sources of updating physicians' knowledge and improving management practice on neonatal pain prevention and treatment. In conclusion, Greek NICU-physicians' perceptions that neonates can experience pain with potentially serious acute and long-term consequences remained strong over the past 20 years. Although physicians' practices on neonatal pain management improved, they are still suboptimal, while significant differences exist among centers. Continuing education, globally accepted management protocols, and readily applied pain assessment tools would further improve the management of procedural pain and stress in neonates.

Pain Scales in Neonates Receiving Mechanical Ventilation in Neonatal Intensive Care Units - Systematic Review

INTRODUCTION

Recently, interest in the problem of proper prevention and monitoring of pain, especially acute, has been increasing in relation to various age groups. Greater awareness of the problem prompts discussion about the purpose of analgesia in newborns treated with mechanical ventilation.

AIM

The purpose of the systematic review was to analyze current research on the use of pain scales in newborns treated with mechanical ventilation in the Neonatal Intensive Care Unit.

METHODS

Medline databases: PubMed, OVID, EBSCO, Web of Science and Cochrane Library were traced using the appropriate keywords. The search was limited to studies in English. The review took into account the years 2006-2019. Considering the criteria, 12 articles were included in further analysis, to which full access was obtained.

RESULTS

The analyzed scientific research showed differences in beliefs about the validity and credibility of the scales used. Researchers indicated that staff with practical experience in using scales in their daily practice was very skeptical of the results obtained on their basis.

CONCLUSION

Based on this review, no explicit evidence can be obtained to support the use of one proper scale in pain assessment. It can be inferred that the COMFORT and N-PASS scales are effective for pain assessment and for determining the need for analgesics in mechanically ventilated neonates. These scales may be equally effective in assessing chronic pain, especially in mechanically ventilated children. On the other hand, the PIPP and CRIES scales are most commonly recommended for assessing acute and postoperative pain.
