Effects of combined use of non-nutritive sucking, oral sucrose, and facilitated tucking on infant behavioural states across heel-stick procedures: a prospective, randomised controlled trial

NON-pharmacological Approach Less Invasive Surfactant Administration (NONA-LISA) trial: protocol for a randomised controlled trial

INTRODUCTION

Using pre-procedure analgesia with the risk of apnoea may complicate the Less Invasive Surfactant Administration (LISA) procedure or reduce the effect of LISA.

METHODS

The NONA-LISA trial (ClinicalTrials.gov, NCT05609877) is a multicentre, blinded, randomised controlled trial aiming at including 324 infants born before 30 gestational weeks, meeting the criteria for surfactant treatment by LISA. Infants will be randomised to LISA after administration of fentanyl 0.5-1 mcg/kg intravenously (fentanyl group) or isotonic saline solution intravenously (saline group). All infants will receive standardised non-pharmacological comfort care before and during the LISA procedure. Additional analgesics will be provided at the clinician's discretion. The primary outcome is the need for invasive ventilation, meaning mechanical or manual ventilation via an endotracheal tube, for at least 30 min (cumulated) within 24 h of the procedure. Secondary outcomes include the modified COMFORTneo score during the procedure, bronchopulmonary dysplasia at 36 weeks, and mortality at 36 weeks.

DISCUSSION

The NONA-LISA trial has the potential to provide evidence for a standardised approach to relief from discomfort in preterm infants during LISA and to reduce invasive ventilation. The results may affect future clinical practice.

IMPACT

Pre-procedure analgesia is associated with apnoea and may complicate procedures that rely on regular spontaneous breathing, such as Less Invasive Surfactant Administration (LISA). This randomised controlled trial addresses the effect of analgesic premedication in LISA by comparing fentanyl with a placebo (isotonic saline) in infants undergoing the LISA procedure. All infants will receive standardised non-pharmacological comfort. The NONA-LISA trial has the potential to provide evidence for a standardised approach to relief from discomfort or pain in preterm infants during LISA and to reduce invasive ventilation. The results may affect future clinical practice regarding analgesic treatment associated with the LISA procedure.

The effect of maternal voice and non-nutritional sucking on repeated procedural pain of heel prick in neonates: a quasi-experimental study

BACKGROUND

Neonates in the neonatal intensive care unit undergo frequent painful procedures. It is essential to reduce pain using safe and feasible methods.

PURPOSE

To evaluate the effects of non-nutritional sucking, mother's voice, or non-nutritional sucking combined with mother's voice on repeated procedural pain in hospitalized neonates.

METHODS

A quasi-experimental study was conducted in which 141 neonates were selected in a hospital in Changsha, China. Newborns were divided into four groups: non-nutritional sucking (NNS) (n = 35), maternal voice (MV) (n = 35), NNS + MV (n = 34), and control (n = 37) groups. The Preterm Infant Pain Profile-Revised Scale (PIPP-R) was used to assess pain.

RESULTS

During the heel prick, the heart rate value and blood oxygen saturation were significantly different between the groups (P < 0.05). Both non-nutritional sucking and maternal voice significantly reduced PIPP-R pain scores of hospitalized newborns (P < 0.05). The pain-relief effect was more robust in the combined group than in other groups.

CONCLUSIONS

This study showed that both non-nutritional sucking and the mother's voice alleviated repeated procedural pain in neonates. Therefore, these interventions can be used as alternatives to reduce repeated procedural pain.

Sucrose analgesia for heel-lance procedures in neonates

BACKGROUND

Sucrose has been examined for calming and pain-relieving effects in neonates for invasive procedures such as heel lance.

OBJECTIVES

To assess the effectiveness of sucrose for relieving pain from heel lance in neonates in terms of immediate and long-term outcomes SEARCH METHODS: We searched (February 2022): CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, Web of Science, and three trial registries.

SELECTION CRITERIA

We included randomised controlled trials where term and/or preterm neonates received sucrose for heel lances. Comparison treatments included water/placebo/no intervention, non-nutritive sucking (NNS), glucose, breastfeeding, breast milk, music, acupuncture, facilitated tucking, and skin-to-skin care.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. We reported mean differences (MD) with 95% confidence intervals (CI) using the fixed-effect model for continuous outcome measures. We assessed heterogeneity by the I2 test. We used GRADE to assess certainty of evidence.

MAIN RESULTS

We included 55 trials (6273 infants): 29 included term neonates, 22 included preterm neonates, and four included both. Heel lance was investigated in 50 trials; 15 investigated other minor painful procedures in addition to lancing. Sucrose vs control The evidence suggests that sucrose probably results in a reduction in PIPP scores compared to the control group at 30 seconds (MD -1.74 (95% CI -2.11 to -1.37); I2 = 62%; moderate-certainty evidence) and 60 seconds after lancing (MD -2.14, 95% CI -3.34 to -0.94; I2 = 0%; moderate-certainty evidence). The evidence is very uncertain about the effects of sucrose on DAN scores compared to water at 30 seconds after lancing (MD -1.90, 95% CI -8.58 to 4.78; heterogeneity not applicable (N/A); very low-certainty evidence). The evidence suggests that sucrose probably results in a reduction in NIPS scores compared to water immediately after lancing (MD -2.00, 95% CI -2.42 to -1.58; heterogeneity N/A; moderate-certainty evidence). Sucrose vs NNS The evidence is very uncertain about the effect of sucrose on PIPP scores compared to NNS during the recovery period after lancing (MD 0.60, 95% CI -0.30 to 1.50; heterogeneity not applicable; very low-certainty evidence) and on DAN scores at 30 seconds after lancing (MD -1.20, 95% CI -7.87 to 5.47; heterogeneity N/A; very low-certainty evidence). Sucrose + NNS vs NNS The evidence is very uncertain about the effect of sucrose + NNS on PIPP scores compared to NNS during lancing (MD -4.90, 95% CI -5.73 to -4.07; heterogeneity not applicable; very low-certainty evidence) and during recovery after lancing (MD -3.80, 95% CI -4.47 to -3.13; heterogeneity N/A; very low-certainty evidence). The evidence is very uncertain about the effects of sucrose + NNS on NFCS scores compared to water + NNS during lancing (MD -0.60, 95% CI -1.47 to 0.27; heterogeneity N/A; very low-certainty evidence). Sucrose vs glucose The evidence suggests that sucrose results in little to no difference in PIPP scores compared to glucose at 30 seconds (MD 0.26, 95% CI -0.70 to 1.22; heterogeneity not applicable; low-certainty evidence) and 60 seconds after lancing (MD -0.02, 95% CI -0.79 to 0.75; heterogeneity N/A; low-certainty evidence). Sucrose vs breastfeeding The evidence is very uncertain about the effect of sucrose on PIPP scores compared to breastfeeding at 30 seconds after lancing (MD -0.70, 95% CI -0.49 to 1.88; I2 = 94%; very low-certainty evidence). The evidence is very uncertain about the effect of sucrose on COMFORTneo scores compared to breastfeeding after lancing (MD -2.60, 95% CI -3.06 to -2.14; heterogeneity N/A; very low-certainty evidence). Sucrose vs expressed breast milk The evidence suggests that sucrose may result in little to no difference in PIPP-R scores compared to expressed breast milk during (MD 0.3, 95% CI -0.24 to 0.84; heterogeneity not applicable; low-certainty evidence) and at 30 seconds after lancing (MD 0.3, 95% CI -0.11 to 0.71; heterogeneity N/A; low-certainty evidence). The evidence suggests that sucrose probably may result in slightly increased PIPP-R scores compared to expressed breast milk 60 seconds after lancing (MD 1.10, 95% CI 0.34 to 1.86; heterogeneity N/A; low-certainty evidence). The evidence is very uncertain about the effect of sucrose on DAN scores compared to expressed breast milk 30 seconds after lancing (MD -1.80, 95% CI -8.47 to 4.87; heterogeneity N/A; very low-certainty evidence). Sucrose vs laser acupuncture There was no difference in PIPP-R scores between sucrose and music groups; however, data were reported as medians and IQRs. The evidence is very uncertain about the effect of sucrose on NIPS scores compared to laser acupuncture during lancing (MD -0.86, 95% CI -1.43 to -0.29; heterogeneity N/A; very low-certainty evidence). Sucrose vs facilitated tucking The evidence is very uncertain about the effect of sucrose on total BPSN scores compared to facilitated tucking during lancing (MD -2.27, 95% CI -4.66 to 0.12; heterogeneity N/A; very low-certainty evidence) and during recovery after lancing (MD -0.31, 95% CI -1.72 to 1.10; heterogeneity N/A; very low-certainty evidence). Sucrose vs skin-to-skin + water (repeated lancing) The evidence suggests that sucrose results in little to no difference in PIPP scores compared to skin-to-skin + water at 30 seconds after 1st (MD 0.13, 95% CI -0.70 to 0.96); 2nd (MD -0.56, 95% CI -1.57 to 0.45); or 3rd lancing (MD-0.15, 95% CI -1.26 to 0.96); heterogeneity N/A, low-certainty evidence for all comparisons. The evidence suggests that sucrose results in little to no difference in PIPP scores compared to skin-to-skin + water at 60 seconds after 1st (MD -0.61, 95% CI -1.55 to 0.33); 2nd (MD -0.12, 95% CI -0.99 to 0.75); or 3rd lancing (MD-0.40, 95% CI -1.48 to 0.68); heterogeneity N/A, low-certainty evidence for all comparisons. Minor adverse events required no intervention.

AUTHORS' CONCLUSIONS

Sucrose compared to control probably results in a reduction of PIPP scores 30 and 60 seconds after single heel lances (moderate-certainty evidence). Evidence is very uncertain about the effect of sucrose compared to NNS, breastfeeding, laser acupuncture, facilitated tucking, and the effect of sucrose + NNS compared to NNS in reducing pain. Sucrose compared to glucose, expressed breast milk, and skin-to-skin care shows little to no difference in pain scores. Sucrose combined with other nonpharmacologic interventions should be used with caution, given the uncertainty of evidence.

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.

Effect of combined procedural pain interventions during neonatal intensive care on sleep, cognitive development, and internalizing behavior: a follow-up analysis of a randomized controlled trial

ABSTRACT

Repeated procedural pain can cause preterm infants to spend excessive time awake at the cost of sleep and can have a detrimental impact on later cognitive and behavioral development. What's more, poor sleep may be correlated with worse cognitive development and more internalizing behaviors in infants and toddlers. In a randomized controlled trial (RCT), we found that combined procedural pain interventions (sucrose, massage, music, nonnutritive sucking, and gentle human touch) during neonatal intensive care could improve preterm infants' early neurobehavioral development. Here, we followed up the participants who were enrolled in the RCT to evaluate the effect of combined pain interventions on later sleep, cognitive development, and internalizing behavior and to determine whether sleep may moderate the effect of combined pain interventions on the cognitive development and internalizing behavior. Total sleep time and night awakenings at 3, 6, and 12 months old; the cognitive development (adaptability, gross motor, fine motor, language, and personal-social domains) at 12 and 24 months old measured by the Chinese version of Gesell Development Scale; and the internalizing behavior at 24 months old measured by the Chinese version of Child Behavior Checklist were assessed. Our findings showed the potential benefits of combined pain interventions during neonatal intensive care for preterm infant's later sleep, motor and language development, and internalizing behavior, and the effect of combined pain interventions on motor development and internalizing behavior might be moderated by the mean total sleep duration and night awakenings at 3, 6, and 12 months old.

Sensorial saturation improves infants' procedure-related pain behaviour in the cardiac intensive care unit: A quasi-experimental study

BACKGROUND

Painful procedures are unavoidable when providing critical care to infants in intensive care units. These adverse experiences during infancy can lead to later hyperalgesia and poor neurodevelopmental outcomes. Thus, appropriate interventions are required to relieve infant pain during these procedures.

OBJECTIVES

This study evaluated the effectiveness of sensorial saturation in reducing pain for infants during jugular central venous catheter removal procedures in intensive care units.

METHODS

This study involved a quasi-experimental, repeated-measures design. Data were collected from participants sequentially recruited from April to June 2019 (control period) and July to September 2019 (experimental period). Participants included 78 infants younger than 1 year with congenital heart disease. The control group (n = 38) received a general nursing intervention using swaddling, a common child-care practice that consists of wrapping infants to restrict movements, whereas the experimental group (n = 40) received sensorial saturation using oral sugar, body massage, and verbal interaction. Infants' physiological reactions to procedural pain were measured by changes in heart rate, oxygen saturation, and respiratory rate. Infants' procedural pain and behavioural indicators were measured using the Modified Behavioural Pain Scale. Data were analysed using descriptive statistics, independent t-tests, χ² tests, and repeated-measures analysis of variance.

RESULTS

Compared with the control group, the experimental group had lower heart rates (F = 53.15, p < .001), respiratory rates (F = 15.19, p < .001), and behavioural pain scores (F = 45.21, p < .001), both during and after the procedure.

CONCLUSIONS

Sensorial saturation can be used as a nursing intervention in infants. Given the many invasive procedures that are part of infant clinical care, sensorial saturation may be a safe analgesic alternative. The findings of this study could lead to the development of evidence-based clinical practice guidelines for the nonpharmacological management of acute pain in infants.

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.

2022 Society of Critical Care Medicine Clinical Practice Guidelines on Prevention and Management of Pain, Agitation, Neuromuscular Blockade, and Delirium in Critically Ill Pediatric Patients With Consideration of the ICU Environment and Early Mobility

RATIONALE

A guideline that both evaluates current practice and provides recommendations to address sedation, pain, and delirium management with regard for neuromuscular blockade and withdrawal is not currently available.

OBJECTIVE

To develop comprehensive clinical practice guidelines for critically ill infants and children, with specific attention to seven domains of care including pain, sedation/agitation, iatrogenic withdrawal, neuromuscular blockade, delirium, PICU environment, and early mobility.

DESIGN

The Society of Critical Care Medicine Pediatric Pain, Agitation, Neuromuscular Blockade, and Delirium in critically ill pediatric patients with consideration of the PICU Environment and Early Mobility Guideline Taskforce was comprised of 29 national experts who collaborated from 2009 to 2021 via teleconference and/or e-mail at least monthly for planning, literature review, and guideline development, revision, and approval. The full taskforce gathered annually in-person during the Society of Critical Care Medicine Congress for progress reports and further strategizing with the final face-to-face meeting occurring in February 2020. Throughout this process, the Society of Critical Care Medicine standard operating procedures Manual for Guidelines development was adhered to.

METHODS

Taskforce content experts separated into subgroups addressing pain/analgesia, sedation, tolerance/iatrogenic withdrawal, neuromuscular blockade, delirium, PICU environment (family presence and sleep hygiene), and early mobility. Subgroups created descriptive and actionable Population, Intervention, Comparison, and Outcome questions. An experienced medical information specialist developed search strategies to identify relevant literature between January 1990 and January 2020. Subgroups reviewed literature, determined quality of evidence, and formulated recommendations classified as "strong" with "we recommend" or "conditional" with "we suggest." Good practice statements were used when indirect evidence supported benefit with no or minimal risk. Evidence gaps were noted. Initial recommendations were reviewed by each subgroup and revised as deemed necessary prior to being disseminated for voting by the full taskforce. Individuals who had an overt or potential conflict of interest abstained from relevant votes. Expert opinion alone was not used in substitution for a lack of evidence.

RESULTS

The Pediatric Pain, Agitation, Neuromuscular Blockade, and Delirium in critically ill pediatric patients with consideration of the PICU Environment and Early Mobility taskforce issued 44 recommendations (14 strong and 30 conditional) and five good practice statements.

CONCLUSIONS

The current guidelines represent a comprehensive list of practical clinical recommendations for the assessment, prevention, and management of key aspects for the comprehensive critical care of infants and children. Main areas of focus included 1) need for the routine monitoring of pain, agitation, withdrawal, and delirium using validated tools, 2) enhanced use of protocolized sedation and analgesia, and 3) recognition of the importance of nonpharmacologic interventions for enhancing patient comfort and comprehensive care provision.

"Holding-Cuddling" and Sucrose for Pain Relief During Venepuncture in Newborn Infants: A Randomized, Controlled Trial (CÂSA)

Objectives: Oral sucrose is commonly used to provide analgesia to neonates during painful procedures, such as venepuncture. The additional benefits of reducing pain during venepuncture when oral sucrose is combined with nonpharmacological strategies have not been extensively studied. This randomized controlled trial compared the efficacy of oral sucrose with nonnutritive sucking vs. oral sucrose with nonnutritive sucking plus "holding-cuddling" for pain management during venepuncture in term infants from birth to 3 months of life. Methods: Seventy-eight infants were equally randomized to receive 24% oral sucrose with nonnutritive sucking (control group) or 24% oral sucrose with nonnutritive sucking plus "holding-cuddling" (being held in a secure, cuddling position; experimental group) before venepuncture. Behavioral response to pain was measured by the 0-10 ranking scale "acute pain for neonates (APN)" at 30 and 60 s after venepuncture. Results: Within the study sample, APN scores were ≥ 2 for 32/68 (47%) infants. "Holding-cuddling" did not significantly reduce mean APN scores at 30 and 60 s, but the rate of infants experiencing a high pain score (APN ≥ 8) at 60 s after the venepuncture was significantly lower in the experimental group compared to controls [4/34 vs. 12/34 (p = 0.04)]. Conclusions: Venepuncture is a painful procedure in newborn and young infants. The implementation of behavioral strategies in association with oral sucrose may mitigate pain during this procedure. Clinical Trial Registration: This trial was registered at http://clinicaltrials.gov/ (NCT number 02803723).

A complex interprofessional intervention to improve the management of painful procedures in neonates

During hospitalization, neonates are exposed to a stressful environment and a high number of painful procedures. If pain is not treated adequately, short‐ and long‐term complications may develop. Despite evidence about neonatal pain and available guidelines, procedural pain remains undertreated. This gap between research and practice is mostly due to limited implementation of evidence‐based knowledge and time constraints. This study describes in detail the development process of a complex interprofessional intervention to improve the management of procedural pain in neonates called NEODOL© (NEOnato DOLore). The framework of the Medical Research Council (MRC) for the development and evaluation of complex interventions was used as a methodological guide for the design of the NEODOL© intervention. The development of the intervention is based on several steps and multiple methods. To report this process, we used the Criteria for Reporting the Development of Complex Interventions in Healthcare (CReDECI 2). Additionally, we evaluated the content of the intervention using a Delphi method to obtain consensus from experts, stakeholders, and parents. The complex interprofessional intervention, NEODOL©, is developed and designed for three groups: healthcare professionals, parents, and neonates for a level IIb neonatal unit at a regional hospital in southern Switzerland. A total of 16 panelists participated in the Delphi process. At the end of the Delphi process, the panelists endorsed the NEODOL© intervention as important and feasible. Following the MRC guidelines, a multimethod process was used to develop a complex interprofessional intervention to improve the management of painful procedures in newborns. Complex interprofessional interventions need theoretical bases, careful development, and integration of stakeholders to provide a comprehensive approach. The NEODOL intervention consists of promising components and has the potential to improve the management of painful procedures and should facilitate the knowledge translation into practice.

Effects of Combined Use of Mother's Breast Milk, Heartbeat Sounds, and Non-Nutritive Sucking on Preterm Infants' Behavioral Stress During Venipuncture: A Randomized Controlled Trial

PURPOSE

Even routine procedures can cause pain and stress, and can be harmful to the fast-growing brain of preterm infants. Mitigating pain and stress with sucrose and analgesics has side effects; thus, an alternate choice is the use of natural breast milk and infants' sensory capabilities. Therefore, this study examined the effects of different integrations of sensory experiences-mother's breast milk odor and taste (BM-OT), heartbeat sounds (HBs), and non-nutritive sucking (NNS)-on preterm infant's behavioral stress during venipuncture.

DESIGN

This study was a prospective, randomized controlled trial.

METHODS

Infants born preterm (<37 weeks' gestational age) were enrolled in the study through convenience sampling, and randomly assigned to the following conditions: (condition 1) routine care (n = 36); (condition 2) BM-OT (n = 33); (condition 3) BM-OT + HBs (n = 33); or (condition 4) BM-OT + HBs + NNS (n = 36). Crying duration from puncture to recovery period was recorded using a voice recorder. Facial actions and body movements were measured using an infant behavioral coding scheme and transformed into frequencies during seven stages: baseline (stage 0), disinfecting (stage 1), venipuncture (stage 2), and the recovery period for 10 minutes (stages 3-6).

FINDINGS

Data were analyzed for 138 preterm infants. The corresponding median times to stop crying for conditions 1, 2, 3, and 4 were 137, 79, 81, and 39 s, respectively; the instantaneous occurrence rates of stopping crying for conditions 2, 3, and 4 were 1.469, 1.574, and 2.996 times greater than for condition 1, respectively. Infants receiving conditions 3 and 4 had significantly fewer occurrences of facial actions (stage 6 and stages 4-6, respectively) and body movements (stages 3-6 for both); however, there were no significant reductions in stress behaviors for condition 2 (BM-OT).

CONCLUSIONS

The combination of BM-OT, HBs, and NNS could be provided to preterm infants as interventions to prevent and reduce behavioral stress, and facilitate pain recovery during venipuncture procedures.

CLINICAL RELEVANCE

Clinicians should be educated about how to recognize preterm infants' behavioral stress, and to incorporate different sensory combinations of respective mothers' BM, HBs, and NNS into painful procedures to help preterm infants recover from distress.

The effect of facilitated tucking position during painful procedure in pain management of preterm infants in neonatal intensive care unit: a systematic review and meta-analysis

We performed a systematic review and meta-analysis to investigate the effects of facilitated tucking position during painful procedure in pain management of preterm infants. We searched MEDLINE, PEDro, SciELO and the Cochrane Library (until June 2019) for randomized controlled trials. An α value ≤ 0.05 was considered significant. Heterogeneity among studies was examined with Cochran's Q and I² statistic, in which values greater than 40% were considered indicative of high heterogeneity and random-effects model was chosen. Analyses were performed with Review Manager 5.3. Fifteen studies met the eligibility criteria, including 664 preterm infants. The meta-analyses showed a significant reduction in pain of - 1.02 (95% CI - 1.7 to - 0.4, N = 216) during endotraqueal suctioning for participants in the facilitated tucking position group (FTPG) compared with routine care group. The meta-analyses showed a non-significant difference in pain - 0.3 (95% CI - 2.05 to - 1.4, N = 88) during heel stick for participants in the FTPG compared with oral glucose group. The meta-analyses showed a non-significant difference in pain for participants in the FTPG compared with oral opioid group 0.2 (95% CI - 1.4 to 1.8, N = 140).Conclusion: Facilitated tucking position may improve the pain during painful procedures.What is Known:• Exposure of premature babies to painful procedures is associated with changes in brain development, regardless of other factors.• Facilitated tucking reduces the expression of pain in premature infants.What is New:• Facilitated tucking position was efficient in pain management of preterm infants when compared to routine care.• Facilitated tucking compared to opioid or oral glucose did not achieve a significant reduction in pain intensity.

Comparison of facilitated tucking and oral dextrose in reducing the pain of heel stick in preterm infants: a randomized clinical trial

BACKGROUND

With the increase in hospitalization of premature infants in emergency departments and the painful procedure in these sectors, appropriate methods of pain relief are required. This study aimed to compare the effect of oral dextrose and facilitated tucking in the reduction of pain during heel sticks in premature infants and assess their effectiveness and feasibility for use in emergency settings.

METHODS

This study was a randomized controlled clinical trial with cross-over design. Sixty infants were recruited from a Neonatal Intensive Care Unit (NICU) at Valiasr hospital in Tehran, Iran from March 2015 to September 2016. They were randomly allocated into three groups (no pain relief method, oral dextrose and facilitated tucking). Six blood samples were collected by heel stick for each infant. Oral dextrose and facilitated tucking were compared with the routine method of blood sampling and pain was measured two times for each method. The pain scores was measured by the Premature Infant Pain Profile (PIPP). Repeated Measure ANOVA, ANOVA and Scheffe post-hoc test were used with SPSS 16.

RESULTS

The pain score's increase during heel stick was significantly lower after using oral dextrose (3.58 ± 0.34) and facilitated tucking (5.58 ± 0.53) in comparison to the routine method (8.91 ± 0.18) of blood sampling (P < 0.001, η² = 0.971). Oral dextrose was more effective than facilitated tucking (P < 0.001, Cohen's d = 4.49). The emergency nurses rated oral dextrose as easier (t = 2.20, df = 118, p = 0.02, Cohen's d = 0.39) and more applicable method (t = 2.99, df = 118, p = 0.003, Cohen's d = 0.54) for the emergency department.

CONCLUSIONS

Facilitated tucking is an effective method of pain reduction which can be used in the absence of oral dextrose, in a situation in which it is contraindicated or in combination with oral dextrose. Based on the increase of infant's admission in emergency department future studies are needed to identify the best method of pain reduction for procedures in this setting.

Effectiveness of Sucrose Used Routinely for Pain Relief and Neonatal Clinical Risk in Preterm Infants: A Nonrandomized Study

BACKGROUND

Preterm infants (PI) requiring the neonatal intensive care unit are exposed to early repetitive pain/distress. Little is known about how pain relief strategies interact with infants' clinical health status, such as severity of illness with pain responses. This study aimed to examine main and interactive effects of routine sucrose intervention and neonatal clinical risk (NCR) on biobehavioral pain reactivity-recovery in PI during painful blood collection procedures.

METHODS

Very low birth weight PI (<1500 g; n=104) were assigned to low and high clinical risk groups, according to the Clinical Risk Index for Babies. Sucrose group (n=52) received sucrose solution (25%; 0.5 mL/kg) 2 minutes before the procedures and control group received standard care. Biobehavioral pain reactivity-recovery was assessed according to the Neonatal Facial Coding System, sleep-wake state scale, crying time, and heart rate at 5 phases (baseline, antisepsis, puncture (P), recovery-dressing, and recovery-resting [R]). Repeated measure ANOVA with mixed-design was performed considering pain assessment phases, intervention group, and NCR.

RESULTS

Independent of NCR, sucrose presented main effect in decreasing neonates' facial activity pain responses and crying time, during P and R. Independent of NCR level or routine sucrose intervention, all neonates displayed activated state in P and decreased biobehavioral responses in R phase. Although no sucrose or NCR effects were observed on physiological reactivity, all neonates exhibited physiological recovery 10 minutes after P, reaching the same heart rate patterns as the baseline.

CONCLUSIONS

Independent of NCR level, sucrose intervention for pain relief during acute painful procedures was effective to reduce pain intensity and increase biobehavioral regulation.

Neonatal Pain: Perceptions and Current Practice

Neonates may experience more than 300 painful procedures throughout their hospitalizations. Prior to 1980, there was a longstanding misconception that neonates do not experience pain. Current studies demonstrate that not only do neonates experience pain but also, due to their immature nervous systems, they are hypersensitive to painful stimuli. Poorly treated pain may lead to negative long-term consequences. Proper assessment of neonate pain is vital. The use of nonpharmacologic treatments may be beneficial in alleviating neonate pain. Pharmacologic treatments in the neonate have been well established. Pharmacologic and nonpharmacologic interventions can be used in conjunction to increase the efficacy of analgesia.

A Systematic Review of Behavioral and Environmental Interventions for Procedural Pain Management in Preterm Infants

PROBLEM

Current research suggests behavioral and environmental interventions to prevent neonatal pain prior to an invasive procedure are rarely administered and seldom documented. The aim of this study was to systematically review findings from published randomized controlled trials that tested the effects of behavioral and environmental procedural pain management interventions on behavioral pain response in preterm infants.

ELIGIBILITY CRITERIA

Randomized controlled trials examining the effects of behavioral and environmental pain management interventions on behavioral pain response in preterm infants were identified. Articles accepted for inclusion met the following criteria: English language, original, peer refereed, randomized controlled clinical trials published within the past 5 years, study sample: preterm infants, setting: neonatal intensive care units, study intervention behavioral and environmental, outcome pain measurement score from valid and reliable pain scale.

SAMPLE

Fourteen randomized controlled trials from a literature search of PubMed and Medline databases were included in this review.

RESULTS

Across all age groups, facilitated tucking, oral sucrose, and kangaroo care decreased behavioral and physiologic pain response alone and in combination with other behavioral and environmental interventions.

CONCLUSION

Among preterm infants, facilitated tucking, oral sucrose, and kangaroo care significantly mitigates biobehavioral pain response associated with acutely painful procedures.

IMPLICATIONS

Evidence suggests that behavioral and environmental interventions can decrease biobehavioral pain response associated with acutely painful procedures in preterm infants. This review highlights the need for rigorous studies to help healthcare providers to build a tailored pain treatment plan for preterm infants.

Sweet Solutions for Analgesia in Neonates in China: A Systematic Review and Meta-Analysis

INTRODUCTION

High-quality synthesized evidence of sweet taste analgesia in neonates exists. However, Chinese databases have never been included in previous systematic reviews of sweet solutions for procedural pain.

OBJECTIVE

To conduct a systematic review of Chinese literature evaluating analgesic effects of sweet solutions for neonates. Data sources: Wang Fang, China National Knowledge Infrastructure and Chinese Biomedical Literature Database. Data extraction and analysis: Two authors screened studies for inclusion and conducted risk of bias ratings and data extraction. A third author resolved any conflicts. Meta-analyses were performed using RevMan 5.2 software, on mean differences in pain outcomes using random effects models.

RESULTS

Thirty-one trials (4999 neonates) were included; 26 trials used glucose, 4 used sucrose, and 1 trial evaluated both solutions. Sweet solutions reduced standardized mean pain scores (n = 21 studies; -1.68, 95% confidence interval -2.08, -1.27) and cry duration (n = 6 studies; -25.60, 95% confidence interval -36.47, -14.72 s) but not heart rate change (n = 7 studies; -17.64, 95% confidence interval -52.71, 17.43). No included studies cited the previously published systematic reviews of sweet solutions.

CONCLUSIONS

This systematic review of Chinese databases showed the same results as previously published systematic reviews. No trials included in this review cited the English systematic reviews, highlighting a parallel research agenda.

Effects of a supportive care bundle on sleep variables of preterm infants during hospitalization

Sleep is important for preterm infants' brain development, but they are frequently exposed to painful procedures in the neonatal intensive care unit (NICU) that disturb their sleep cycle and affect their growth. The purpose of this study was to examine the prolonged effects of a supportive care bundle (modulation of the infants' states, non-nutritive sucking, facilitated tucking, and oral sucrose feeding) on preterm infants' sleep variables (sleep efficiency, total sleep time, sleep latency, and frequency of wake bouts) during hospitalization. The team recruited 65 preterm infants (gestational age at birth 28-36 weeks, average birth weight 1,652 g) from a Level III NICU at a medical center in Taiwan. Infants were randomly assigned to one of two treatment conditions to be administered while receiving intrusive procedures: (1) control condition (usual care, including routine procedures, positioning, and gentle touch); or (2) intervention condition in which the supportive care bundle was added to usual care. Sleep variables were measured using actigraphy for a baseline of three continuous days on the 6th to 8th days after birth and again for 3 continuous days when infants weighed ≧1,950 g. Two forms of generalized estimating equation analyses with control of significant covariates were used for data analysis. The supportive care bundle not only significantly increased sleep efficiency and total sleep time but also significantly decreased duration of sleep latency and frequency of wake bouts. These results provide evidence to support the incorporation of the supportive care bundle into NICU clinical practice during intrusive procedures.

Trauma-informed care in the newborn intensive care unit: promoting safety, security and connectedness

Both babies and their parents may experience a stay in the newborn intensive care unit (NICU) as a traumatic or a 'toxic stress,' which can lead to dysregulation of the hypothalamic-pituitary-adrenal axis and ultimately to poorly controlled cortisol secretion. Toxic stresses in childhood or adverse childhood experiences (ACEs) are strongly linked to poor health outcomes across the lifespan and trauma-informed care is an approach to caregiving based on the recognition of this relationship. Practitioners of trauma-informed care seek to understand clients' or patients' behaviors in light of previous traumas they have experienced, including ACEs. Practitioners also provide supportive care that enhances the client's or patient's feelings of safety and security, to prevent their re-traumatization in a current situation that may potentially overwhelm their coping skills. This review will apply the principles of trauma-informed care, within the framework of the Polyvagal Theory as described by Porges, to care for the NICU baby, the baby's family and their professional caregivers, emphasizing the importance of social connectedness among all. The Polyvagal Theory explains how one's unconscious awareness of safety, danger or life threat (neuroception) is linked through the autonomic nervous system to their behavioral responses. A phylogenetic hierarchy of behaviors evolved over time, leveraging the mammalian ventral or 'smart' vagal nucleus into a repertoire of responses promoting mother-baby co-regulation and the sense of safety and security that supports health and well-being for both members of the dyad. Fostering social connectedness that is mutual and reciprocal among parents, their baby and the NICU staff creates a critical buffer to mitigate stress and improve outcomes of both baby and parents. Using techniques of trauma-informed care, as explained by the Polyvagal Theory, with both babies and their parents in the NICU setting will help to cement a secure relationship between the parent-infant dyad, redirecting the developmental trajectory toward long-term health and well-being of the baby and all family members.

Factors Associated With Preterm Infants’ Circadian Sleep/Wake Patterns at the Hospital

This prospective repeated-measures study explored potential factors (postmenstrual age, body weight, gender, chronological age, illness severity, and circadian rhythm) related to preterm infants’ circadian sleep/wake patterns. Circadian sleep/wake patterns were measured using an Actiwatch for 3 continuous days in preterm infants (gestational age of 28-36.4 weeks) in a neonatal intensive care unit and hospital nursery. Potential factors associated with circadian sleep/wake patterns were analyzed using the generalized estimating equation. For our sample of 30 preterm infants, better sleep/wake patterns were associated with male gender, younger postmenstrual and chronological age, lower body weight, and less illness severity. Preterm infants’ total sleep time ( B = 41.828, p < .01) and percentage of sleep time ( B = 3.711, p < .01) were significantly longer at night than during the day. These findings can help clinicians recognize preterm infants’ sleep problems, signaling the need to provide individualized support to maintain these infants’ sleep quality during their early life.

Systematic review of nonpharmacological analgesic interventions for common needle-related procedure in newborn infants and development of evidence-based clinical guidelines

The aim of this literature review was to develop clinical guidelines for the prevention and control of needle-related pain in newborn infants. The guidelines were developed by the Italian Society of Neonatology, using the Grading of Recommendations, Assessment, Development and Evaluation approach, based on the assessment of 232 papers published between 1986 and 2015. The quality of the evidence was high or moderate for some behavioural and nonpharmacological interventions.

CONCLUSION

There was sufficient evidence to strongly support the use of nonpharmacological interventions for common needle-related procedures in newborn infants. Combined interventions seemed to be more effective in relieving procedural pain.

Non-pharmacological measures in preterm newborns submitted to arterial puncture

OBJECTIVE

to assess pain in preterm newborns and to compare the neonatal and therapeutic variables with the total scores of the Neonatal Facial Coding System of preterm newborns submitted to arterial puncture exposed to music and 25% oral glucose.

METHOD

a comparative study with 48 recordings of preterm newborns - Group 1, music (26); Group 2, glucose 25% (22) - individually analyzed by three trained nurses, after Kappa of at least 80%.

RESULTS

the variables and the pain scores of the groups did not present statistical significance (p < 0.05) according to the Neonatal Facial Coding System. 80.8% of the preterm infants in Group 1 had a higher quantitative score ≥ 3 in the neonatal variables (gender, type of delivery), and therapeutic variables (type of oxygen therapy, place of hospitalization, type of puncture).

CONCLUSION

There was no difference when comparing the music and glucose 25% groups and the variables studied.

Effects of combined oral sucrose and nonnutritive sucking (NNS) on procedural pain of NICU newborns, 2001 to 2016: A PRISMA-compliant systematic review and meta-analysis

BACKGROUND

Both oral sucrose (OS) and nonnutritive sucking (NNS) are effective nonpharmacological methods to alleviate procedures pain in neonatal intensive care unit (NICU) newborns when they were used alone, but the combined effect of OS+NNS remains controversial. So, we conducted this study to evaluate the efficiency of NNS combined with oral sucrose on pain relief in NICU newborns undergoing painful procedures.

METHODS

We searched PubMed, Ovid (Medline), Embase (Medline), Cochrane Central Library, and other resources such as Google Scholar, bibliographies of included literatures for all available articles. Two reviewers screened literatures and extracted data independently. The fixed effects model was used to pool the results using Reviewer Manager (RevMan) 5.3. As each study included in our meta-analysis had been approved by Ethics Committee or institutional review board, thus our study did not need ethical approval.

RESULTS

Seven randomized controlled trials, including 599 participants, were contained in our meta-analysis. The combination of oral sucrose and NNS is associated with reduced pain scores (mean difference [MD], -0.52; 95% confidence interval [CI], -0.68 to -0.36); shortened crying time (MD,-0.92; 95% CI, -1.39 to -0.44); but the 2 groups did not differ significantly in reducing bradycardia (MD, 0.73; 95% CI, 0.32-1.68), tachycardia (MD, 0.65; 95% CI, 0.38-1.10), or desaturations (MD, 0.73; 95% CI, 0.32-1.68).

CONCLUSION

The pooled evidence indicates that the combination measures may serve as an evidence-based guideline for pain relief among patients having minor pain. Besides, it also indicates that OS combined with NNS can be an alternative for better prevention and management of procedure pain in NICU newborns. Nevertheless, the results may be limited due to incomplete data, and thus, more randomized controlled trials or well-designed studies are required to determine the effects of OS+NNS in the future.

Sweet Solutions to Reduce Procedural Pain in Neonates: A Meta-analysis

CONTEXT

Abundant evidence of sweet taste analgesia in neonates exists, yet placebo-controlled trials continue to be conducted.

OBJECTIVE

To review all trials evaluating sweet solutions for analgesia in neonates and to conduct cumulative meta-analyses (CMAs) on behavioral pain outcomes.

DATA SOURCES

(1) Data from 2 systematic reviews of sweet solutions for newborns; (2) searches ending 2015 of CINAHL, Medline, Embase, and psychINFO.

DATA EXTRACTION AND ANALYSIS

Two authors screened studies for inclusion, conducted risk-of-bias ratings, and extracted behavioral outcome data for CMAs. CMA was performed using random effects meta-analysis.

RESULTS

One hundred and sixty-eight studies were included; 148 (88%) included placebo/no-treatment arms. CMA for crying time included 29 trials (1175 infants). From the fifth trial in 2002, there was a statistically significant reduction in mean cry time for sweet solutions compared with placebo (-27 seconds, 95% confidence interval [CI] -51 to -4). By the final trial, CMA was -23 seconds in favor of sweet solutions (95% CI -29 to -18). CMA for pain scores included 50 trials (3341 infants). Results were in favor of sweet solutions from the second trial (0.5, 95% CI -1 to -0.1). Final results showed a standardized mean difference of -0.9 (95% CI -1.1 to -0.7).

LIMITATIONS

We were unable to use or obtain data from many studies to include in the CMA.

CONCLUSIONS

Evidence of sweet taste analgesia in neonates has existed since the first published trials, yet placebo/no-treatment, controlled trials have continued to be conducted. Future neonatal pain studies need to select more ethically responsible control groups.

Sucrose for analgesia in newborn infants undergoing painful procedures

BACKGROUND

Administration of oral sucrose with and without non-nutritive sucking is the most frequently studied non-pharmacological intervention for procedural pain relief in neonates.

OBJECTIVES

To determine the efficacy, effect of dose, method of administration and safety of sucrose for relieving procedural pain in neonates as assessed by validated composite pain scores, physiological pain indicators (heart rate, respiratory rate, saturation of peripheral oxygen in the blood, transcutaneous oxygen and carbon dioxide (gas exchange measured across the skin - TcpO2, TcpCO2), near infrared spectroscopy (NIRS), electroencephalogram (EEG), or behavioural pain indicators (cry duration, proportion of time crying, proportion of time facial actions (e.g. grimace) are present), or a combination of these and long-term neurodevelopmental outcomes.

SEARCH METHODS

We used the standard methods of the Cochrane Neonatal. We performed electronic and manual literature searches in February 2016 for published randomised controlled trials (RCTs) in the Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library, Issue 1, 2016), MEDLINE (1950 to 2016), EMBASE (1980 to 2016), and CINAHL (1982 to 2016). We did not impose language restrictions.

SELECTION CRITERIA

RCTs in which term or preterm neonates (postnatal age maximum of 28 days after reaching 40 weeks' postmenstrual age), or both, received sucrose for procedural pain. Control interventions included no treatment, water, glucose, breast milk, breastfeeding, local anaesthetic, pacifier, positioning/containing or acupuncture.

DATA COLLECTION AND ANALYSIS

Our main outcome measures were composite pain scores (including a combination of behavioural, physiological and contextual indicators). Secondary outcomes included separate physiological and behavioural pain indicators. We reported a mean difference (MD) or weighted MD (WMD) with 95% confidence intervals (CI) using the fixed-effect model for continuous outcome measures. For categorical data we used risk ratio (RR) and risk difference. We assessed heterogeneity by the I(2) test. We assessed the risk of bias of included trials using the Cochrane 'Risk of bias' tool, and assessed the quality of the evidence using the GRADE system.

MAIN RESULTS

Seventy-four studies enrolling 7049 infants were included. Results from only a few studies could be combined in meta-analyses and for most analyses the GRADE assessments indicated low- or moderate-quality evidence. There was high-quality evidence for the beneficial effect of sucrose (24%) with non-nutritive sucking (pacifier dipped in sucrose) or 0.5 mL of sucrose orally in preterm and term infants: Premature Infant Pain Profile (PIPP) 30 s after heel lance WMD -1.70 (95% CI -2.13 to -1.26; I(2) = 0% (no heterogeneity); 3 studies, n = 278); PIPP 60 s after heel lance WMD -2.14 (95% CI -3.34 to -0.94; I(2) = 0% (no heterogeneity; 2 studies, n = 164). There was high-quality evidence for the use of 2 mL 24% sucrose prior to venipuncture: PIPP during venipuncture WMD -2.79 (95% CI -3.76 to -1.83; I(2) = 0% (no heterogeneity; 2 groups in 1 study, n = 213); and intramuscular injections: PIPP during intramuscular injection WMD -1.05 (95% CI -1.98 to -0.12; I(2) = 0% (2 groups in 1 study, n = 232). Evidence from studies that could not be included in RevMan-analyses supported these findings. Reported adverse effects were minor and similar in the sucrose and control groups. Sucrose is not effective in reducing pain from circumcision. The effectiveness of sucrose for reducing pain/stress from other interventions such as arterial puncture, subcutaneous injection, insertion of nasogastric or orogastric tubes, bladder catherization, eye examinations and echocardiography examinations are inconclusive. Most trials indicated some benefit of sucrose use but that the evidence for other painful procedures is of lower quality as it is based on few studies of small sample sizes. The effects of sucrose on long-term neurodevelopmental outcomes are unknown.

AUTHORS' CONCLUSIONS

Sucrose is effective for reducing procedural pain from single events such as heel lance, venipuncture and intramuscular injection in both preterm and term infants. No serious side effects or harms have been documented with this intervention. We could not identify an optimal dose due to inconsistency in effective sucrose dosage among studies. Further investigation of repeated administration of sucrose in neonates is needed. There is some moderate-quality evidence that sucrose in combination with other non-pharmacological interventions such as non-nutritive sucking is more effective than sucrose alone, but more research of this and sucrose in combination with pharmacological interventions is needed. Sucrose use in extremely preterm, unstable, ventilated (or a combination of these) neonates needs to be addressed. Additional research is needed to determine the minimally effective dose of sucrose during a single painful procedure and the effect of repeated sucrose administration on immediate (pain intensity) and long-term (neurodevelopmental) outcomes.

Analgesia, nil or placebo to babies, in trials that test new analgesic treatments for procedural pain

This review assessed how often neonates in control groups experienced unnecessary pain during clinical trials involving procedural pain. We retrieved 45 studies in the 30 months up to June 2015 and found that in 29 (64%) the control babies received either placebos or no treatment. Placebos were used in 15/25 (60%) studies involving heel pricks and in 6/8 (75%) involving venepuncture.

CONCLUSION

Despite international guidelines, neonates included in control groups during painful procedures do not receive analgesia in the majority of cases. Several historical reasons can explain this, but in the light of present knowledge, this should not continue. Ethical committees are thereof invited since now to not permit clinical trials that do not explicitly rule out pain during treatments and journals are invited to not publish them.

Non-pharmacological management of infant and young child procedural pain

BACKGROUND

Infant acute pain and distress is commonplace. Infancy is a period of exponential development. Unrelieved pain and distress can have implications across the lifespan.  This is an update of a previously published review in the Cochrane Database of Systematic Reviews, Issue 10 2011 entitled 'Non-pharmacological management of infant and young child procedural pain'.

OBJECTIVES

To assess the efficacy of non-pharmacological interventions for infant and child (up to three years) acute pain, excluding kangaroo care, and music. Analyses were run separately for infant age (preterm, neonate, older) and pain response (pain reactivity, immediate pain regulation). 

SEARCH METHODS

For this update, we searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (Issue 2 of 12, 2015), MEDLINE-Ovid platform (March 2015), EMBASE-OVID platform (April 2011 to March 2015), PsycINFO-OVID platform (April 2011 to February 2015), and CINAHL-EBSCO platform (April 2011 to March 2015). We also searched reference lists and contacted researchers via electronic list-serves. New studies were incorporated into the review. We refined search strategies with a Cochrane-affiliated librarian. For this update, nine articles from the original 2011 review pertaining to Kangaroo Care were excluded, but 21 additional studies were added.

SELECTION CRITERIA

Participants included infants from birth to three years. Only randomised controlled trials (RCTs) or RCT cross-overs that had a no-treatment control comparison were eligible for inclusion in the analyses. However, when the additive effects of a non-pharmacological intervention could be assessed, these studies were also included. We examined studies that met all inclusion criteria except for study design (e.g. had an active control) to qualitatively contextualize results. There were 63 included articles in the current update.

DATA COLLECTION AND ANALYSIS

Study quality ratings and risk of bias were based on the Cochrane Risk of Bias Tool and GRADE approach. We analysed the standardized mean difference (SMD) using the generic inverse variance method.

MAIN RESULTS

Sixty-three studies, with 4905 participants, were analysed. The most commonly studied acute procedures were heel-sticks (32 studies) and needles (17 studies). The largest SMD for treatment improvement over control conditions on pain reactivity were: non-nutritive sucking-related interventions (neonate: SMD -1.20, 95% CI -2.01 to -0.38) and swaddling/facilitated tucking (preterm: SMD -0.89; 95% CI -1.37 to -0.40). For immediate pain regulation, the largest SMDs were: non-nutritive sucking-related interventions (preterm: SMD -0.43; 95% CI -0.63 to -0.23; neonate: SMD -0.90; 95% CI -1.54 to -0.25; older infant: SMD -1.34; 95% CI -2.14 to -0.54), swaddling/facilitated tucking (preterm: SMD -0.71; 95% CI -1.00 to -0.43), and rocking/holding (neonate: SMD -0.75; 95% CI -1.20 to -0.30). Fifty two of our 63 trials did not report adverse events. The presence of significant heterogeneity limited our confidence in the findings for certain analyses, as did the preponderance of very low quality evidence.

AUTHORS' CONCLUSIONS

There is evidence that different non-pharmacological interventions can be used with preterms, neonates, and older infants to significantly manage pain behaviors associated with acutely painful procedures. The most established evidence was for non-nutritive sucking, swaddling/facilitated tucking, and rocking/holding. All analyses reflected that more research is needed to bolster our confidence in the direction of the findings. There are significant gaps in the existing literature on non-pharmacological management of acute pain in infancy.

Nonpharmacological management of pain during common needle puncture procedures in infants: current research evidence and practical considerations

All infants undergo painful procedures involving skin puncture as part of routine medical care. Pain from needle puncture procedures is suboptimally managed. Numerous nonpharmacologic interventions are available for these painful procedures, including swaddling, holding, skin-to-skin care, pacifier, sweet-tasting solutions, and breast-feeding. Adoption of nonpharmacologic pain-relieving interventions into routine clinical practice is feasible and should be a standard of care in the delivery of quality health care for infants. This review summarizes current knowledge about the epidemiology of pain from common needle puncture procedures in infants, the effectiveness of nonpharmacologic interventions, implementation considerations, and unanswered questions for future research.
