The effect of nalbuphine on prevention of emergence delirium in children: a systematic review with meta-analysis

BACKGROUND

Emergence delirium remains a major postoperative concern for children undergoing surgery. Nalbuphine is a synthetic mixed agonist-antagonist opioid, which is believed to reduce the incidence of emergence delirium in children. The primary objective was to examine the effect of nalbuphine on emergence delirium in children undergoing surgery.

METHODS

Databases of MEDLINE, EMBASE, and CENTRAL were searched from their starting dates until April 2023. Randomized Clinical Trials (RCT) and observational studies comparing nalbuphine and control in children undergoing surgery were included.

RESULTS

Eight studies (n = 1,466 patients) were eligible for inclusion of data analysis. Compared to the control, our pooled data showed that the nalbuphine group was associated with lower incidence of emergence delirium (RR = 0.38, 95% CI [0.30, 0.47], p < 0.001) and reduced postoperative pain scores (MD = -0.98, 95% CI [-1.92, -0.04], p = 0.04).

CONCLUSIONS

This review showed the administration of nalbuphine is associated with significant decrease in the incidence of emergence delirium and postoperative pain scores among children undergoing surgery. However, due to limited sample size, high degree of heterogeneity and low level of evidence, future adequately powered trials are warranted to explore the efficacy of nalbuphine on emergence delirium among the pediatric population.

Peritraumatic Pain in Child Maltreatment: A Systematic Literature Review

Extensive research has been conducted on the link between trauma, child maltreatment (CM), and chronic pain. Although the risk of suffering from chronic pain among CM survivors has been established, much less is known about the experience of pain during CM incidents or whether such peritraumatic pain sensations are associated with later chronic pain. This scoping review was conducted to synthesize the existing literature on pain during and a short time following CM (i.e., peritraumatic pain). Utilizing the preferred reporting items for systematic reviews and meta-analyses guidelines, the current review included 11 manuscripts, which met the following criteria: (a) refer to physical pain experienced during or a short time after CM, (b) were published in peer-reviewed journals, and (c) were written in English. The review demonstrated that most of the included studies were not intentionally focused on peritraumatic pain, the majority used qualitative research methods, and all were cross-sectional. Furthermore, although validated questionnaires are available, most of the studies did not utilize such measures. Those that intentionally reported pain demonstrated its high intensity and prevalence in CM incidents, indicating that pain is inherently embedded in the experience of maltreatment. The findings spotlight an underdeveloped research realm on a phenomenon that may hold significant empirical, clinical, and legal implications. Research endeavors should initiate interdisciplinary bodies of knowledge to establish well-validated research methodologies that properly quantify peritraumatic pain in trauma and CM.

A prospective, observational validation of HRAD±, a novel pediatric affect and cooperation scale

STUDY OBJECTIVE

HRAD± was developed to quickly assess pediatric perioperative affect and cooperation. HRAD± represents: Happy, Relaxed, Anxious, Distressed, with a yes/no answer to cooperativity. The primary aim of this study was to investigate the clinical utility of HRAD± as an affect and cooperation assessment tool for inhalational mask induction. Secondary aims examined inter-rater reliability (IRR) of HRAD± and predictive validity of induction HRAD± with emergence delirium.

DESIGN

This was a prospective observational investigation.

SETTING

We conducted this investigation at Lucile Packard Children's Hospital Stanford, an academic, quaternary care children's hospital in Northern California.

PATIENTS

A total of 197 patients were included in this investigation. Children 1-14 years of age, who underwent daytime procedures with inhalational induction of anesthesia and American Society of Anesthesiologists physical status I-III were eligible.

INTERVENTIONS

During mask induction, two trained research assistants (RAs) independently scored the patient's affect and cooperation. After extubation, the same investigators observed the patient's emergence.

MEASUREMENTS

RAs scored each mask induction using the following scales: HRAD±, modified Yale Preoperative Anxiety Scale (mYPAS), Observation Scale of Behavioral Distress (OSBD), and Induction Compliance Checklist (ICC). Correlations were calculated to HRAD±. IRR of HRAD± between the RAs as well as predictive validity of HRAD± to Pediatric Anesthesia Emergence Delirium (PAED), Watcha and Cravero scales were calculated.

MAIN RESULTS

HRAD± scores strongly correlated with mYPAS (r = 0.840, p < 0.0001) with moderate correlation to OSBD (r = 0.685, p < 0.0001) and ICC (-0.663, p < 0.0001). IRR was moderate for the affect and cooperation portion of the HRAD± scale, respectively (κ = 0.595 [p < 0.0001], κ = 0.478 [p < 0.0001]). A weak correlation was observed with PAED (r = 0.134 [p = 0.0597]) vs HRAD±. No correlations were observed between Watcha (r = 0.013 [p = 0.8559]) and Cravero and HRAD± scales (r = 0.002 [p = 0.9767]).

CONCLUSIONS

HRAD± is a clinically useful and simple scale for evaluating pediatric affect and cooperation during inhalational mask induction. Results demonstrate correlation with commonly utilized research assessment scales.

Perioperative pain management for cleft palate surgery: a systematic review and procedure-specific postoperative pain management (PROSPECT) recommendations

BACKGROUND/IMPORTANCE

Cleft palate surgery is associated with significant postoperative pain. Effective pain control can decrease stress and agitation in children undergoing cleft palate surgery and improve surgical outcomes. However, limited evidence often results in inadequate pain control after cleft palate surgery.

OBJECTIVES

The aim of this review was to evaluate the available evidence and to develop recommendations for optimal pain management after cleft palate surgery using procedure-specific postoperative pain management (PROSPECT) methodology.

EVIDENCE REVIEW

MEDLINE, Embase, and Cochrane Databases were searched for randomized controlled trials and systematic reviews assessing pain in children undergoing cleft palate repair published in English language from July 2002, through August 2023.

FINDINGS

Of 1048 identified studies, 19 randomized controlled trials and 4 systematic reviews met the inclusion criteria. Interventions that improved postoperative pain, and are recommended, include suprazygomatic maxillary nerve block or palatal nerve block (if maxillary nerve block cannot be performed). Addition of dexmedetomidine to local anesthetic for suprazygomatic maxillary nerve block or, alternatively, as intravenous administration perioperatively is recommended. These interventions should be combined with a basic analgesic regimen including acetaminophen and nonsteroidal anti-inflammatory drugs. Of note, pre-incisional local anesthetic infiltration and dexamethasone were administered as a routine in several studies, however, because of limited procedure-specific evidence their contribution to pain relief after cleft palate surgery remains unknown.

CONCLUSION

The present review identified an evidence-based analgesic regimen for cleft palate surgery in pediatric patients.

Use and Abuse of Electrocautery in Adenoidectomy Hemostasis

Background and objectives: Bipolar electrocautery is commonly used to control bleeding after cold-instrument pediatric adenoidectomy, but the surgeon should be aware of the possible side effects. OBJECTIVE: The aim of our study is to investigate the effects of bipolar electrocautery when used for bleeding control at the end of an adenoidectomy procedure. Materials and Methods: We evaluated the effect of electrocautery on postoperative pain, velopharyngeal insufficiency symptoms, postoperative nasal obstruction, and rhinorrhea in a group of 90 children undergoing adenoidectomy in our ENT department over a period of 3 months. Results: After statistically analyzing the data, we found that the duration of postoperative pain, the duration of rhinorrhea and nasal obstruction, and the duration of painkiller administration, as well as the velopharyngeal insufficiency symptoms, were significantly longer in patients in whom electrocautery was used for hemostasis. A significantly higher incidence of posterior neck pain and halitosis (oral malodor) was noted in the patients in whom electrocautery was used for adenoidectomy hemostasis. Conclusions: Bipolar electrocautery use should be limited during pediatric adenoidectomy hemostasis because of the possible side effects: longer postoperative pain, prolonged nasal obstruction, rhinorrhea and velopharyngeal insufficiency, and halitosis. We noted some side effects that were specific to electrocautery use during adenoidectomy: posterior neck pain and oral malodor. Acknowledging the risk for these symptoms can help to alleviate the anxiety of both the parents and the patients regarding the expected postoperative outcomes.

Factors Associated With Low Procedural Pain Scores Among 1- to 5-Year-Old Patients Undergoing Facial Laceration Repair

OBJECTIVES

Our objectives were to quantify pain experienced by young children undergoing facial laceration repair and identify factors associated with low procedural pain scores.

METHODS

We conducted a prospective cohort study of children's distress among a convenience sample of children aged 1 to 5 years undergoing facial or scalp laceration repair in 2 pediatric emergency departments. We reviewed video recordings and documented pain scores at 15-second intervals using the Face, Leg, Activity, Cry, Consolability-Revised (FLACC-r) scale. We dichotomized FLACC-r into low/high scores (≤3 and >3) to evaluate practice variables.

RESULTS

We included 11,474 FLACC-r observations from 258 procedures in the analysis. Two-thirds of 3- to 5-year-olds completed their laceration repair without the use of restraint, sedation, or anxiolytics. Mean distress scores were low (≤2.5 out of 10) across all procedure phases for 2- to 5-year-old patients. One-year-old patients experienced significantly more distress than their older counterparts (mean ≤4.2 out of 10). Odds of having low FLACC scores (≤3) were greater for patients with an expert clinician (adjusted odds ratio [aOR]: 1.72; 95% confidence interval [CI], 1.05-2.84). Wound infiltration (aOR, 0.35; 95% CI, 0.13-0.93), patient observation of a needle (aOR, 0.21; 95% CI, 0.14-0.33), and restraint (aOR, 0.04; 95% CI, 0.02-0.06) were negatively associated with low FLACC score.

CONCLUSION

The majority of 3- to 5-year-old patients were able to undergo facial laceration repair without restraint, sedation, or anxiolytics and with low mean distress scores. Our findings suggest that children's risk of experiencing moderate and severe distress during facial and scalp laceration repair may be reduced by prioritizing wound closure by expert-level clinicians, ensuring effective lidocaine-epinephrine-tetracaine application, avoiding restraint, and concealing needles from patient view.

Error traps in acute pain management in children

Providing effective acute pain management to hospitalized children can help improve outcomes, decrease length of stay, and increase patient and parental satisfaction. Error traps (circumstances that lead to erroneous actions or undesirable consequences) can result in inadequately controlled pain, unnecessary side effects, and adverse events. This article highlights five error traps encountered when managing acute pain in children. They include failure to appropriately assess pain, optimally utilize regional anesthesia, select suitable systemic analgesics, identify and treat medication-related side effects, and consider patient characteristics when choosing medication or dosing route. These issues are easily addressed when the clinician is cognizant of ways to anticipate, identify, and mitigate or avoid these errors.

Effect of using vacutainers with cartoon characters on the pain and fear levels of preschoolers during bloodletting

AIM

Our study aims to analyse the effect of using a vacutainer with cartoon characters on preschoolers' pain and fear levels during the bloodletting process.

METHODS

The experimental, randomised controlled clinical trial was conducted with 102 children aged 3-6 years, randomised into control and experimental groups. The bloodletting routine was applied to the control group. The vacutainer of each child in the experimental group was covered with the illustration of their chosen cartoon character and blood was drawn with it. The fear and pain levels during the bloodletting procedure were examined in both groups.

RESULTS

Pain and fear levels were significantly lower in the experimental group than in the experimental group (P < 0.05).

CONCLUSIONS

Our research highlighted that using a cartoon character sticker with a vacutainer can reduce preschoolers' pain and fear during bloodletting.

Discriminant properties of the Behavioral Pain Scale for assessment of procedural pain-related distress in ventilated children

OBJECTIVES

Children hospitalized in a pediatric intensive care unit (PICU) are frequently exposed to distressing and painful medical procedures and interventions. There is a lack of clinical scales to measure procedural pain-related distress in ventilated children. The Behavioral Pain Scale (BPS) was initially developed to detect procedural pain in critically ill adults. This study aims to assess the BPS's discriminant properties for measuring procedural pain-related distress in ventilated pediatric patients incorporating two instruments validated for pediatric patients.

METHODS

This prospective exploratory study was performed with ventilated children admitted to the interdisciplinary 14-bed PICU of the University Children's Hospital, University Medical Center Hamburg-Eppendorf, Germany. The nurse in charge and an independent observer simultaneously assessed the patients using German versions of the BPS, the COMFORT-B scale (CBS), and the modified Face, Legs, Activity, Cry, Consolability (mFLACC) scale immediately before and during endotracheal suctioning.

RESULTS

We analyzed 170 parallel assessments in n=34 ventilated children. Patients were (mean ± SD) 9.5 ± 4.8 years old. Internal consistency for the BPS was excellent (α=0.93). We found a high rater agreement for all clinical scales (BPS: k=0.73, CBS: k=0.80, mFLACC: k=0.71). Strong correlations were identified between BPS and CBS (r=0.89) and BPS and mFLACC (r=0.79). The BPS cutoff values showed likewise excellent results (area under the curve CBS >16: 0.97; mFLACC >2: 0.91).

CONCLUSIONS

In our population of ventilated children, the BPS was well suited to detect procedural pain-related distress compared with two validated pain scales. Further extensive validation studies should follow to support our findings.

Effects of Virtual Reality Education on Procedural Pain and Anxiety During Venipuncture in Children: A Randomized Clinical Trial

Background

Venipuncture is one of the most frequent and frightening medical procedures for children. This randomized clinical trial aimed to evaluate whether pre-procedural immersive virtual reality (VR) education could decrease pain and anxiety during venipuncture procedure of children.

Methods

Sixty children scheduled for venipuncture at the phlebotomy unit were randomized into either the control or VR group. Before the procedure, children of the control group received conventional simple verbal instructions, whereas those of the VR group experienced a 4-min VR education regarding venipuncture. The primary outcome was the pain and anxiety of pediatric patients assessed with the children’s hospital of eastern ontario pain scale. Secondary outcomes were parental satisfaction, venipuncture time, repeated procedure and procedural difficulty rated by phlebotomists.

Results

The pain and anxiety score during the procedure was significantly lower in the VR group than in the control group (median [IQR], 6.0 [5.0–7.0] vs. 8.0 [6.0–9.8], P = 0.001). Parental satisfaction about the procedural process were higher in the VR group than in the control group (P = 0.029), and the degree of procedural difficulty was lower in the VR group, compared to the control group (P = 0.026).

Conclusion

The preprocedural VR education significantly reduced pain and anxiety of children and decreased the procedural difficulty of phlebotomists during venipuncture procedure.

Peritraumatic Pain in Child Sexual Abuse: Children's Descriptions of Pain as Conveyed in Their Testimonies Following Child Sexual Abuse

The literature on child sexual abuse (CSA) has contributed significantly to the understanding of its characteristics, epidemiology, and consequences. Considerably less attention has been dedicated, however, to the subjective experiences of the abused children, and more specifically to their experiences of pain. The current study explored the way children perceive and describe pain during and shortly following incidents of sexual abuse. The sample was comprised of 35 transcripts of forensic interviews following alleged CSA. Thematic analysis of the children's narratives identified three themes: (a) pain during the abusive incidents, described using words indicating its intensity and quality; (b) pain shortly after the abusive incidents, including weeks later, and (c) pain as embedded within the complex dynamic with perpetrator. The children struggled to localize the pain, mainly using words such as "inside" and "deep." Moreover, they testified that in the course of the abusive incidents, they were often silenced when trying to communicate their pain to the perpetrators. The children's narratives provided us with a unique opportunity to learn about the pain not only during the abusive incidents but also following it. Additionally, children described suffering from pain in areas that were not directly injured during the CSA incidents, mainly referring to the head, abdomen and legs. The discussion addresses the potential intervening factors in peritraumatic CSA pain, as well as its potential links with chronic post-traumatic physical and mental morbidity. This study illuminates the necessity to address the complicated links between short- and long-term physical, emotional, cognitive, and interpersonal manifestations of CSA.

A randomized controlled study: The effect of preprocedurals ınformative animation watch about echocardiography and ıntraprocedural kaleidoscope watch on anxiety in children

AIM

This study was conducted as a randomized controlled study to investigate the effect of procedural cartoons displayed before echocardiography and kaleidoscope display during the procedure on anxiety in children aged 5-12 years.

METHODS

The study was completed with 164 children aged 5-12 years who were admitted for echocardiography. The study was conducted with four groups: cartoons group, kaleidoscope group, cartoons + kaleidoscope group, and control group. Data were collected using a follow-up form and the Children's Fear Scale.

RESULTS

The results showed that the cartoons, kaleidoscope, and cartoons + kaleidoscope groups had lower anxiety scores during the procedure than during the preprocedural period (p < .001). In the control group, there was no significant difference between anxiety scores before the procedure and during the procedure (p > .05).

CONCLUSION

The present study concluded that cartoon display for preparing children aged 5-12 years or distracting them during the procedure using a kaleidoscope was effective in reducing their anxiety.

Pain Assessment in Pediatric Emergency Departments: A National Survey

OBJECTIVE

Accurate and consistent assessment of pain is essential in the pediatric emergency setting. Despite recommendations for formal assessment protocols, current data are lacking on pain assessment in pediatric emergency departments (EDs) and, specifically, whether appropriate tools are being used for different age groups. Our aim was to determine the status of pain assessment in US pediatric EDs.

METHODS

We disseminated an online cross-sectional survey (after piloting) to pediatric EDs within the Children's Hospital Association. Responses were analyzed for each question owing to incomplete responders. We report descriptive statistics, with categorical variables compared with χ2 (P < 0.05 considered statistically significant).

RESULTS

From 120 pediatric EDs, we received 57 responses (48%). Most respondents (28/49, 57%) were from freestanding pediatric centers. All 57 EDs (100%) performed formal pain assessments, with 31 (63%) of 49 using an ED-specific protocol. Freestanding children's hospitals were more likely to have ED-specific protocols (21/31, 68%) than nonfreestanding (10/31, 32%) (P = 0.04). Among 56 responders, 100% stated that nurses are tasked with assessing pain. For children 0 to 2 years, 29 (54%) of 54 used the Face, Legs, Activity, Cry, Consolability scale. Numerical scales were increasingly used with older ages: 3 to 4 years, 40 (80%) of 50; 5 to 10 years, 49 (98%) of 50; and 11 to 21 years, 50 (100%) of 50.

CONCLUSIONS

In contrast to prior research, US pediatric EDs are routinely assessing pain with scales that are mostly appropriate for their respective age groups. Further research is needed to explore barriers to implementing appropriate pain ratings for all children and, ultimately, how these assessments impact the care of children in the emergency setting.

Development and assessment of an efficient pediatric affect and cooperation scale

STUDY OBJECTIVE

HRAD± was developed to quickly evaluate pediatric preprocedural affect and cooperativity during mask induction of anesthesia and peripheral intravenous (PIV) placement. HRAD± represents: Happy, Relaxed, Anxious, Distressed, with a yes/no answer to cooperativity. The primary aim of this study was to compare HRAD± to previously published scales.

DESIGN

We conducted an observational study.

SETTING

Videos of pediatric patients were collected in the perioperative environment.

PATIENTS

Twenty-four children, twenty-one pediatric anesthesiologists and twenty pediatric perioperative providers were included.

INTERVENTIONS

To assess the reliability of HRAD±, standard patient videos were created. Children underwent mask induction or PIV placement, and these interventions were video recorded. Mask induction and PIV placement videos were rated by pediatric anesthesiologists and perioperative non-physician providers respectively using HRAD±.

MEASUREMENTS

Two trained researchers provided the modified Yale Preoperative Anxiety Scale (mYPAS), Observation Scale of Behavioral Distress (OSBD), and Induction Compliance Checklist (ICC) scores, and we calculated correlations to HRAD±, inter-rater reliability, and intra-rater reliability.

MAIN RESULTS

HRAD± scores strongly correlated with mYPAS (r = 0.846, p < 0.0001) and OSBD scores (r = 0.723, p < 0.0001). Cooperativity scores correlated strongly with ICC scores in the mask induction group (r = -0.715, p < 0.0001) and in the PIV group (r = -0.869, p < 0.0001). HRAD± inter-rater reliability for mask induction was 0.414 (p < 0.0001) and for PIV assessment was 0.378 (p < 0.0001). Inter-rater reliability for cooperativity on mask induction was 0.797 (p < 0.0001) and PIV assessment was 0.683 (p < 0.0001). Intra-rater reliability for mask induction was 0.675 and PIV assessments was 0.678. Intra-rater reliability for cooperativity for mask induction was 0.894 and for PIV assessments was 0.765.

CONCLUSIONS

HRAD± is an efficient and reliable scale that serves as a practical alternative for measuring pediatric affect during mask induction and PIV placement. The results demonstrate strong correlation with commonly utilized yet more complex affect scales.

Behavioral Strategies to Minimize Procedural Distress During In-Office Pediatric Tympanostomy Tube Placement Without Sedation or Restraint

The purpose of this study was to evaluate behavioral strategies to minimize procedural distress associated with in-office tympanostomy tube placement for children without general anesthesia, sedation, or papoose-board restraints. 120 6-month- to 4-year-olds and 102 5- to 12-year-olds were treated at 16 otolaryngology practices. Mean age of children was 4.7 years old (SD = 3.18 years), with more boys (58.1%) than girls (41.9%). The cohort included 14% Hispanic or Latinx, 84.2% White, 12.6% Black, 1.8% Asian and 4.1% ‘Other’ race and ethnicity classifications. The in-office tube placement procedure included local anesthesia via lidocaine/epinephrine iontophoresis and tube placement using an integrated and automated myringotomy and tube delivery system. Behavioral strategies were used to minimize procedural distress. Anxiolytics, sedation, or papoose board were not used. Pain was measured via the faces pain scale-revised (FPS-R) self-reported by the children ages 5 through 12 years. Independent coders supervised by a psychologist completed the face, legs, activity, cry, consolability (FLACC) behavior observational rating scale to quantify children’s distress. Mean FPS-R score for tube placement was 3.30, in the “mild’ pain range, and decreased to 1.69 at 5-min post-procedure. Mean tube placement FLACC score was 4.0 (out of a maximum score of 10) for children ages 6 months to 4 years and was 0.4 for children age 5–12 years. Mean FLACC score 3-min post-tube placement was 1.3 for children ages 6 months to 4 years and was 0.2 for children age 5–12 years. FLACC scores were inversely correlated with age, with older children displaying lower distress. The iontophoresis, tube delivery system and behavioral program were associated with generally low behavioral distress. These data suggest that pediatric tympanostomy and tube placement can be achieved in the outpatient setting without anxiolytics, sedatives, or mechanical restraints.

Analgesic Efficacy of Quadratus Lumborum Block in Infants Undergoing Pyeloplasty

Post-operative analgesic management is challenging in infants and opioids have been the standard of care. However, they are associated with adverse effects which may negatively impact infants. In this retrospective cohort study, we sought to explore the postoperative analgesic efficacy of quadratus lumborum (QL) block in the infant population undergoing dorsal lumbotomy pyeloplasty. Chart review of 34 infants (≤12 months) who underwent dorsal lumbotomy pyeloplasty between 2016–2020 was performed. Post-operative pain was assessed using externally validated pain scales (CRIES & FLACC) and monitored hemodynamics (pulse and blood pressure). Opioid doses were standardized by using morphine milligram equivalency (MME). The Prescription Database Monitoring Program (PDMP) was utilized to determine if discharge opioid prescriptions were filled. Of 34 patients, 13 received the QL block. Mean age at the time of surgery was 6.2 months ± 3.2 months. The QL group received 0.8 MME postoperatively, whereas the non-QL group received 0.9 MME (p = 0.82). The QL group (20%) filled their discharge opioid prescription less frequently compared to non-QL group (100%) (p = 0.002). There were no observed differences between pain scale or hemodynamic variables. Further studies are warranted to explore QL block’s efficacy for post-operative infant pain management.

Virtual Reality vs. Tablet Video as an Experiential Education Platform for Pediatric Patients Undergoing Chest Radiography: A Randomized Clinical Trial

Virtual reality (VR), which offers an immersive experience, has been implemented into the education of pediatric patients to reduce peri-procedural anxiety. This randomized clinical trial evaluated the effect of VR, compared with standard video, on reducing anxiety and distress in pediatric patients undergoing chest radiography. A total of 120 children aged 4 to 8 years with scheduled chest radiography appointments were randomized into either the tablet or the VR group. Children in the tablet group experienced chest radiography indirectly with a 3 min tablet video, whereas those in the VR group received the same content via a VR experience. The distress of children was measured using the Observational Scale of Behavioral Distress (OSBD) scale. Parental presence and procedural outcomes were also recorded. The number of less distressed children (OSBD score < 5) was significantly higher in the VR group than in the tablet group (49 [81.7%]) vs. 32 [53.3%]) (p = 0.001). The OSBD scores, the need for parental presence, the procedure time, and the number of repeated procedures were all lower in the VR group. The immersive VR experience appears to decrease the degree of anxiety in children and increase the efficiency of the procedures compared with the tablet video with the same content.

Cold Vibration (Buzzy) Versus Anesthetic Patch (EMLA) for Pain Prevention During Cannulation in Children: A Randomized Trial

INTRODUCTION

The purpose of this study was to assess differences in observed pain-related behaviors during cannulation between a device combining cold and vibration (Buzzy) and the standard care (EMLA patch).

METHODS

Patients 18 months to 6 years old, requiring venous access in a pediatric emergency department, received either the Buzzy device or the EMLA patch. Predefined week randomization ensured equal allocation to the 2 intervention groups. Pain during cannulation was measured using the Children's Hospital of Eastern Ontario Pain Scale. Parent and nurse reports, cannulation success, and venous access times were also assessed.

RESULTS

In total, 607 included patients were randomized into the Buzzy group (n = 302) or the EMLA group (n = 305). Observed pain-related behaviors scores, parent-assessed pain scores, and nurse-reported pain ratings were higher with Buzzy.

CONCLUSIONS

Pain relief by a combination of cold and vibration during cannulation is not as effective as the standard-care method in children 18 months to 6 years old.

Surgical management of the patient living with autism

Background

Although 1 in 59 children currently born are diagnosed with autism spectrum disorder (ASD), little is known on how to best manage those patients who require surgical intervention.

The purpose of this study is to (1) investigate the best care strategies for surgical patients living with autism spectrum disorder (2) provide recommendations on how to apply those strategies to clinical practice.

Methods

A literature review was conducted to investigate the best clinical practices for optimizing surgical care for individuals living with autism spectrum disorder. Relevant articles were selected and examined, and individual references from those articles were manually searched using Ovid Medline and Google Scholar.

Results

The wide spectrum of symptoms associated with autism spectrum disorder pose unique challenges for surgical management. Early coordination with the patient and family optimizes the development of an effective care plan. Strategies include identifying triggers for anxiety as well as soothing mechanisms, performing surgery in the morning, completing preoperative paperwork prior to surgery, choosing appropriate analgesia and anxiolytics, and fast resumption of normal routines. Based on these findings a surgical checklist was created to aid in treating the patient with autism spectrum disorder. The checklist provides insight into navigating the surgical experience and emphasizes planning surgical interventions to most effectively fit individual patient needs.

Conclusion

The surgical treatment of those living with autism spectrum disorder poses unique challenges for the health care team. The widespread adoption of such individualized approaches encompassing pre/intra/post-operative will become more important as these children grow into adults with increased needs for surgical services.

•

Early coordination optimizes development of an effective care plan.

•

Identifying triggers for anxiety as well as soothing mechanisms can be helpful.

•

Performing surgery first in the morning decreases deviation from normal routines.

•

Completing preoperative paperwork prior to surgery reduces surgical day work.

•

Choosing appropriate analgesia and anxiolytics assists in surgical interventions.

Intranasal Ketamine for Treatment of Acute Pain in Pediatrics: A Systematic Review

OBJECTIVES

Intranasal ketamine has not been well studied in acute pain treatment and does not have a recognized place in therapy in current practice guidelines for pediatric patients. Ketamine has a unique mechanism of action with a favorable side effect profile that may provide benefit to the pediatric population for acute pain. The purpose of this review is to summarize the evidence evaluating intranasal ketamine versus any other comparator for children who require acute pain treatment.

METHODS

A systematic review was performed to include clinical studies of intranasal ketamine for acute pain that reported any pain-related outcome and adverse events in children 0 to 17 years old. Trials were identified through PubMed, Google Scholar, clinical trial registries, research registries, and key journals through April 2018. The Jadad scoring system was used to assess the methodological quality of the included randomized controlled trials.

RESULTS

Six studies consisting of 261 patients were reviewed. Intranasal ketamine demonstrated pain relief in all included clinical studies; however, there was inconsistency in dosing, comparators, scales, and indications. Two of the randomized controlled trials were rated as high quality, and 1 randomized controlled trial was rated as poor quality on the Jadad scale.

CONCLUSIONS

Intranasal ketamine was safe and effective in the 6 clinical studies included in this systematic review.

Does practising hypnosis-derived communication techniques by oncology nurses translate into reduced pain and distress in their patients? An exploratory study

Objectives

To explore the effects of a hypnotic communication (HC) training for paediatric nurses in decreasing patients' pain and distress during venipunctures.

Methods

A 4-day theoretical and practical HC training was offered to five paediatric oncology nurses. The effects of HC were tested with 22 young cancer patients (13 girls, 9 boys, 10 ± 4 years) over four time points, with 88 encounters being video-recorded and coded in stable professional-patient dyads. Patients' pain and distress were rated by patients and parents with visual analogue scales and coded from recordings using the Faces, Legs, Activity, Cry and Consolability (FLACC) scale.

Results

We observed a significant decrease in pre-post distress reported by parents (d = 0.45, p = 0.046). Two out of five nurses with higher skills acquisition had larger reduction in patients' self-reported pain (d = 1.03, p = 0.028), parents perceived pain (d = 1.09, p = 0.042), distress (d = 1.05, p = 0.043) as well as observed pain (d = 1.22, p = 0.025). Favourable results on pain and distress did not maintain at follow-up.

Conclusion and clinical implications

Training nurses in HC may translate into improved pain and distress in patients, both self-rated and observed provided that skills are used in practice. HC training is a promising non-pharmacological intervention to address pain in paediatrics.

A practical guide to acute pain management in children

In the pediatric population, pain is frequently under-recognized and inadequately treated. Improved education and training of health care providers can positively impact the management of pain in children. The purpose of this review is to provide a practical clinical approach to the management of acute pain in the pediatric inpatient population. This will include an overview of commonly used pain management modalities and their potential pitfalls. For institutions that have a pediatric acute pain service or are considering initiating one, it is our hope to provide a useful tool to aid clinicians in the safe and effective treatment of pain in children.

Content and construct validity of the Diagnostic Criteria for Temporomandibular Disorders Axis I for children

OBJECTIVE

To perform the content and construct validation of the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) Axis I, for children 7-11 years old.

MATERIALS AND METHODS

A Delphi process was used to perform the content validity of the DC/TMD Axis I. One hundred eighty-nine 7- to 11-year-old children were assessed with the adapted instrument. Confirmatory factor analysis (CFA) was used to investigate construct validity of the DC/TMD for children. A baseline one-factor model was compared against a two-factor (Model 2) and a seven-factor (Model 3) models based on the original DC/TMD. Root mean squared error of approximation (RMSEA), comparative fit index (CFI), chi-square, change in chi-square and Cronbach's α were used to analyse the data. All analyses were performed in STATA^© version 13.0.

RESULTS

Items of the DC/TMD were reduced, "history time" was changed to 2 weeks, pain intensity was assessed through a face scale, and language was adapted to be better understood by children. The amount of muscle pressure was maintained as in the original DC/TMD Axis I. The CFA led to a two- and a seven-factor model, with good fit. The internal consistency of Model 2 was .91 and of Model 3, .94.

CONCLUSION

The results of this study provide evidence to support a seven-factor representation of the DC/TMD Axis I for 7- to 11-year-old children, as well as a two-factor structure. Such findings will begin to provide researchers with confidence in the properties of this instrument when considering its inclusion in clinical research.

Pediatric Clinical Endpoint and Pharmacodynamic Biomarkers: Limitations and Opportunities

Medical research in children typically lags behind that of adult research in both quantity and quality. The conduct of rigorous clinical trials in children can raise ethical concerns because of children's status as a 'vulnerable' population. Moreover, carrying out studies in pediatrics also requires logistical considerations that rarely occur with adult clinical trials. Due to the relatively smaller number of pediatric studies to support evidence-based medicine, the practice of medicine in children is far more reliant upon expert opinion than in adult medicine. Children are at risk of not receiving the same level of benefits from precision medicine research, which has flourished with new technologies capable of generating large amounts of data quickly at an individual level. Although progress has been made in pediatric pharmacokinetics, which has led to safer and more effective dosing, gaps in knowledge still exists when it comes to characterization of pediatric disease and differences in pharmacodynamic response between children and adults. This review highlights three specific therapeutic areas where biomarker development can enhance precision medicine in children: asthma, type 2 diabetes mellitus, and pain. These 'case studies' are meant to update the reader on biomarkers used currently in the diagnosis and treatment of these conditions, and their shortcomings within a pediatric context. Current research on surrogate endpoints and pharmacodynamic biomarkers in the above therapeutic areas will also be described. These cases highlight the current lack in pediatric specific surrogate endpoints and pharmacodynamic biomarkers, as well as the research presently being conducted to address these deficiencies. We finally briefly highlight other therapeutic areas where further research in pediatric surrogate endpoints and pharmacodynamic biomarkers can be impactful to the care of children.

Validation of the Greek Version of Comfort-B, FLACC, and BPS Scales in Critically Ill Children and Their Association with Clinical Severity

BACKGROUND

A variety of valid pediatric pain assessment tools are used in clinical practice globally; however, none have been validated for use in the Pediatric Intensive Care Unit (PICU) in Greece. Furthermore, the association between pain behavioral responses and clinical status is unclear.

AIMS

To assess the reliability and validity of the Greek version of FLACC, Comfort B, and BPS pain scales in critically ill children and to explore their association with clinical severity (Denver MOF, PMODS) and levels of sedation and analgesia.

METHODS

A methodological and descriptive correlational study was performed in a 6-bed PICU. A total of 60 observations in a sample of 30 children (mean age 4.1 years; 63.3% male) were obtained by 2 independent nurses during rest and painful procedures. At the same time, the bedside nurse assessed the child's pain intensity using the VASobs.

RESULTS

High internal consistency and strong interrater reliability were detected (Cronbach's alpha ≥ .85; ICC > .95, p < .001). The agreement between observers was satisfactory (0.71 ≤ Kappa ≤ 0.96, p < .001). Strong correlations were found among the scales (0.65 ≤ rho ≤0 .98, p < .05). Increased pain scores (≥moderate pain) were observed during painful procedures regardless the administration of analgesia. Statistically significant correlations were found between clinical severity and the FLACC and Comfort B scores (-0.577 ≤ rho ≤ -0.384, p < .05).

CONCLUSIONS

These pain tools were found to be suitable for this sample of children in Greece. Wider application of these tools in Greek PICUs and further research regarding their association with the clinical severity and the pain responses is required for the improvement of pain management in critically ill children.

Why Unidimensional Pain Measurement Prevails in the Pediatric Acute Pain Context and What Multidimensional Self-Report Methods Can Offer

Although pain is widely recognized to be a multidimensional experience and defined as such, unidimensional pain measurement focusing on pain intensity prevails in the pediatric acute pain context. Unidimensional assessments fail to provide a comprehensive picture of a child's pain experience and commonly do little to shape clinical interventions. The current review paper overviews the theoretical and empirical literature supporting the multidimensional nature of pediatric acute pain. Literature reporting concordance data for children's self-reported sensory, affective and evaluative pain scores in the acute pain context has been reviewed and supports the distinct nature of these dimensions. Multidimensional acute pain measurement holds particular promise for identifying predictive markers of chronicity and may provide the basis for tailoring clinical management. The current paper has described key reasons contributing to the widespread use of unidimensional, rather than multidimensional, acute pediatric pain assessment protocols. Implications for clinical practice, education and future research are considered.

Effect of Immersive Virtual Reality Education Before Chest Radiography on Anxiety and Distress Among Pediatric Patients: A Randomized Clinical Trial

IMPORTANCE

Pediatric patients often encounter anxiety and distress in hospital settings, and virtual reality education, providing a vivid, immersive, and realistic experience, has been introduced to mitigate these anxiety responses.

OBJECTIVE

To evaluate whether virtual reality education for pediatric patients before chest radiography could reduce anxiety and distress in children and improve the radiographic process.

DESIGN, SETTING, AND PARTICIPANTS

This prospective randomized clinical trial was conducted in a tertiary academic hospital in Seongnam, Republic of Korea. Participants (n = 112) were children aged 4 to 8 years who underwent chest radiography between July 20, 2018, and September 11, 2018. Analysis was performed from October 2, 2018, to April 23, 2019.

INTERVENTIONS

Children were randomized to simple verbal instruction (control group) or 3-minute virtual reality education explaining the process of chest radiography in detail and leading to appropriate cooperation (virtual reality group).

MAIN OUTCOMES AND MEASURES

The primary outcome was anxiety and distress among pediatric patients based on behavioral observations using the amended version of the Observational Scale of Behavioral Distress scale for radiology procedures (total score of 30, with a score <5 indicating less distressed and a score ≥5 indicating more distressed). Secondary outcomes were the need of parental presence, parental satisfaction score, procedure time, number of repeated images, and process difficulty score.

RESULTS

Of 99 children included in the final analysis, 50 (50.5%) were allocated to the control group (mean [SD] age, 5.6 [1.2] years; 26 boys [52.0%]) and 49 (49.5%) to the virtual reality group (mean [SD] age, 5.8 [1.3] years; 32 boys [65.3%]). The mean (SD) score for anxiety and distress (2.0 [3.7] vs 5.0 [6.1]; mean difference, 3.0 [95% CI, 1.0-5.0]; P = .004), need for parental presence (8 cases with parents present [16.3%] vs 18 cases with parents present [36.0%]), and mean (SD) procedure time (55.1 [21.6] seconds vs 75.0 [42.0] seconds) were lower in the virtual reality group than in the control group. The mean (SD) score for parental satisfaction (9.4 [1.4] vs 8.6 [2.0]) was higher in the virtual reality group than in the control group.

CONCLUSIONS AND RELEVANCE

Virtual reality education before chest radiography improved the radiography experience among pediatric patients by reducing anxiety, distress, and procedure time while increasing parents' satisfaction.

The Society for Pediatric Anesthesia recommendations for the use of opioids in children during the perioperative period

Opioids have long held a prominent role in the management of perioperative pain in adults and children. Published reports concerning the appropriate, and inappropriate, use of these medications in pediatric patients have appeared in various publications over the last 50 years. For this document, the Society for Pediatric Anesthesia appointed a taskforce to evaluate the available literature and formulate recommendations with respect to the most salient aspects of perioperative opioid administration in children. The recommendations are graded based on the strength of the available evidence, with consensus of the experts applied for those issues where evidence is not available. The goal of the recommendations was to address the most important issues concerning opioid administration to children after surgery, including appropriate assessment of pain, monitoring of patients on opioid therapy, opioid dosing considerations, side effects of opioid treatment, strategies for opioid delivery, and assessment of analgesic efficacy. Regular updates are planned with a re-release of guidelines every 2 years.

POSTOPERATIVE PAIN AND STRESS RESPONSE: DOES CHILD'S GENDER HAVE AN INFLUENCE?

Surgical procedure causes multisystem stress response reactions. The aim of this study was to assess whether gender has an impact on the level of neuroendocrine response to surgical stress and intensity of postoperative pain in children undergoing inguinal hernia repair surgery, as well as satisfaction of their parents with preoperative and postoperative care. The study included 60 children aged 3-6 years, all of them the only child in the family. All children included in the study were categorized as American Society of Anesthesiologists PS Class I, and divided into two groups: group 1 composed of 30 boys and group 2 composed of 30 girls. After oral premedication with midazolam, general anesthesia with endotracheal intubation was performed in all patients. Ketorolac, 1 mg.kg^-1, was administered for postoperative analgesia. Serum cortisol was measured in all children preoperatively and postoperatively. The quality of postoperative analgesia was evaluated by Wong-Baker (FACES) scale, along with parental satisfaction. Male children who were the only child in the family had stronger neuroendocrine response to surgical stress and stronger intensity of postoperative pain. The parents of the girls expressed greater satisfaction with preoperative and postoperative care.

Do clowns attenuate pain and anxiety undergoing botulinum toxin injections in children?

OBJECTIVE

Botulinum toxin injection (BTI) is the primary treatment for spasticity in children. Anxiety and pain are important concerns to address to attenuate the discomfort of BTI. The aim of this study was to compare the effectiveness of medical clowns and usual distractions, both added to nitrous oxide (N₂O) and analgesic cream, on pain and anxiety during BTI sessions in children.

METHODS

The primary outcome was pain evaluated by the Face, Legs, Activity, Cry, Consolability (FLACC) scale. Secondary criteria were pain rated on a Visual Analog Scale (VAS) by the child and parent, anxiety rated on a VAS before and during BTIs by the child and parent(s), rating of the success of the sessions on a 4-point Likert scale by the physician and parent(s), and rating of the benefits of the distraction by the parent(s). Non-parametric tests were used for between-group comparisons.

RESULTS

Baseline group characteristics of the clown and control groups did not differ. During 88 BTI sessions (40 with clown distraction and 48 with control distraction) in 59 children (35 boys; 52 with cerebral palsy, 12 with moderate to severe cognitive disorders), median maximal FLACC score was 2.5 (interquartile range [IQR]: 1-4) in the clown group and 3 (IQR: 1-4.3) in the control group. VAS self-reported pain score was 2.5 (IQR: 0-5) and 3 (IQR: 1-6.3) in the clown and control groups (P=0.56), and VAS proxy-reported pain score was 2.5 (IQR: 0.3-3.4) and 3 (IQR: 1-4.5) (P=0.25). After BTI sessions, the 2 groups did not differ in VAS self- and proxy-reported anxiety (P=0.83 and P=0.81). Physician and parent ratings of the success of sessions were similar between the groups (P=0.89 and P=0.11). Parent ratings of the perceived benefits of distraction were higher in the clown than control group (P=0.004).

CONCLUSIONS

Although clown distraction was particularly appreciated by parents, it did not significantly reduce pain or anxiety in children as compared with usual distraction.

Paediatric Pain Medicine: Pain Differences, Recognition and Coping Acute Procedural Pain in Paediatric Emergency Room

Paediatric pain and its assessment and management are challenging for medical professionals, especially in an urgent care environment. Patients in a paediatric emergency room (PER) often undergo painful procedures which are an additional source of distress, anxiety, and pain. Paediatric procedural pain is often underestimated and neglected because of various myths, beliefs, and difficulties in its evaluation and treatment. However, it is very different from other origins of pain as it can be preventable. It is known that neonates and children can feel pain and that it has long-term effects that last through childhood into adulthood. There are a variety of pain assessment tools for children and they should be chosen according to the patient’s age, developmental stage, communication skills, and medical condition. Psychological factors such as PER environment, preprocedural preparation, and parental involvement should also be considered. There are proven methods to reduce a patient’s pain and anxiety during different procedures in PER. Distraction techniques such as music, videogames, virtual reality, or simple talk about movies, friends, or hobbies as well as cutaneous stimulation, vibration, cooling sprays, or devices are effective to alleviate procedural pain and anxiety. A choice of distraction technique should be individualized, selecting children who could benefit from nonpharmacological pain treatment methods or tools. Nonpharmacological pain management may reduce dosage of pain medication or exclude pharmacological pain management. Most nonpharmacological treatment methods are cheap, easily accessible, and safe to use on every child, so it should always be a first choice when planning a patient’s care. The aim of this review is to provide a summary of paediatric pain features, along with their physiology, assessment, management, and to highlight the importance and efficacy of nonpharmacological pain management in an urgent paediatric care setting.

[Evaluation of pain in children of 2, 4 and 6 months after the application of non-pharmacological analgesia methods during vaccination]

INTRODUCTION

Young children perceive pain as much, or even more than adults, and the pain may have short- and long-term consequences. The literature describes the use of non-pharmacological interventions to alleviate pain during vaccination. The aim of this study was to assess 3such interventions for analgesia during vaccination: non-nutritive sucking (NNS), breastfeeding (BF), and administration of a 50% dextrose solution (D50W).

MATERIALS AND METHODS

A prospective, non-randomised cohort study was carried out on infants aged 2, 4 and 6 months that received 1, 2, or 3 vaccines, respectively, according to the routine immunisation schedule. There were 3treatments: NNS, BF, and 2mL of D50W combined with NNS. Pain was assessed using the LLANTO scale, and the duration of crying.

RESULTS

The study included 387 infants. The mean scores in the LLANTO scale at ages 2 and 6 months were significantly lower in breastfed infants compared to infants managed with NNS (P=.025 and P<.001, respectively), or infants given D50W (P=.025 and P=.001), and the difference was not statistically significant at age 4 months (P=.21 and P=.27). There were no significant differences between infants managed with NNS and D50W at 2, 4, and 6 months (P=.66, P=.93 and P=.45, respectively). The duration of crying was significantly lower at age 6 months in breastfeed infants compared to infants managed with NNS or D50W (P=.013 and P=.017). No breastfed child (n=129) experienced side effects.

CONCLUSIONS

In infants born to term with adequate weight for gestational age, breastfeeding reduces pain on the administration of 1 or 2 vaccines. When 3 vaccines are given, the reduction is minimal. Administration of D50W does not have any additional analgesic effect in infants compared to being held by a parent combined with NNS during vaccination. BF during vaccination is not associated with any side effects.

The Effect of Gamification through a Virtual Reality on Preoperative Anxiety in Pediatric Patients Undergoing General Anesthesia: A Prospective, Randomized, and Controlled Trial

The use of gamification in healthcare has been gaining popularity. This prospective, randomized, clinical trial was designed to evaluate whether gamification of the preoperative process-via virtual reality (VR) gaming that provides a vivid, immersive and realistic experience-could reduce preoperative anxiety in children. Seventy children scheduled for elective surgery under general anesthesia were randomly divided into either the control or gamification group. Children in the control group received conventional education regarding the preoperative process, whereas those in the gamification group played a 5 min VR game experiencing the preoperative experience. Preoperative anxiety, induction compliance checklist (ICC), and procedural behavior rating scale (PBRS) were measured. Sixty-nine children were included in the final analysis (control group = 35, gamification = 34). Preoperative anxiety (28.3 [23.3⁻36.7] vs. 46.7 [31.7⁻51.7]; p < 0.001) and intraoperative compliance measured using ICC (p = 0.038) were lower in the gamification group than in the control group. However, PBRS (p = 0.092) and parent/guardian satisfaction (p = 0.268) were comparable between the two groups. VR experience of the preoperative process could reduce preoperative anxiety and improve compliance during anesthetic induction in children undergoing elective surgery and general anesthesia.

Evaluation of patient-reported outcome measurements as a reliable tool to measure acceptability of the taste of paediatric medicines in an inpatient paediatric population

OBJECTIVE

To evaluate the age appropriateness and suitability of patient-reported outcome measures to assess the acceptability of the taste of oral liquid medicines in children.

DESIGN AND SETTING

An observational mixed-methods study involving children aged 2-16 years taking oral liquid medicine in paediatric inpatient wards across the West Midlands (UK). Assessment tools included patient-reported scores on the taste of medicines via a five-point Facial Hedonic Scale; a Visual Analogue Scale (VAS); a question, 'Did you think the medicine tasted OK?' and researcher observations of facial expressions and behaviours immediately before, during and after administration.

RESULTS

611 children participated. The percent unable to complete the scales was 7% (n=46) for the VAS; 2% (n=15) for the hedonic scale and 1% (n=7) for the question about taste. Significant correlations (Spearman's r) were observed between the patient-reported outcome measures: 0.80 and 0.78 for the taste question and hedonic and VAS, respectively, and 0.84 for the hedonic and VAS. Researcher observations demonstrated the ability of the patient to take the medicine as intended but did not provide sensitive measures of taste. 5% of administrations were not taken as intended by the children. Medicines known to have poor taste (clarithromycin and prednisolone) showed mean hedonic and VAS scores of ≥3.5 and >65 mm, respectively.

CONCLUSIONS

Patient-reported outcome measures correlate with each other and are a useful means to assess the taste (and acceptability) of medicines. Hedonic scales are better understood by children and should be the first choice tool in the assessment of medicines taste.

A Systematic Review of the Psychometric Properties of the Modified Behavioral Pain Scale (MBPS)

PROBLEM

Clinicians and researchers require a valid way to assess procedural pain experienced by infants and children. The Modified Behavioral Pain Scale (MBPS) has been used to assess immunisation pain. However, it is unknown whether it is valid for this purpose and whether use can be extended to other procedures. The aim of this study was to rigorously assess evidence addressing the psychometric properties of this scale and to provide recommendations for its use.

ELIGIBILITY CRITERIA

Psychometric evaluation studies reporting feasibility, reliability, validity, or utility data for the MBPS applied to children (birth to 18years) and randomised controlled trials (RCT) using the MBPS were included.

SAMPLE

Twenty-eight studies (8 psychometric and 20 RCTs) were included.

RESULTS

Studies were of varying quality. Sufficient data was available to cautiously accept the MBPS as valid for assessing immunisation related pain in infants aged 2 to 22months. There was insufficient data to support the psychometrics in other age groups or in circumstances other than immunisation. There is no data addressing the clinical utility of the MBPS.

CONCLUSIONS

It is not possible at this time to confidently accept the MBPS as suitable for assessing all procedural pain in young children.

IMPLICATIONS

Studies to evaluate the capacity of the MBPS to assess pain in a range of procedures and to distinguish between pain and non-pain related distress are needed if it is to be recommended.

The Psychometric Properties of the FLACC Scale Used to Assess Procedural Pain

The Face, Legs, Activity, Cry, and Consolability (FLACC) scale is one of the most commonly and widely used behavioral observation pain scales. The aim of this study was to test the psychometric and practical properties of the FLACC scale to quantify procedural pain in infants and young children. Twenty-six clinicians independently applied the FLACC scale to segments of video collected from 100 children aged 6 to 42 months undergoing a procedure. Video segments were scored by 4 reviewers. Inter- and intrarater reliability coefficients were high (.92 and .87, respectively). Linear mixed modeling confirmed scale responsiveness (differences in difference between FLACC scores across phases for painful versus nonpainful procedures was 4.2, 95% confidence interval = 3.67-4.81). Sensitivity and specificity were 94.9% and 73.5%, respectively, at a cutoff of 2. However, the mean difference across phases for children with baseline scores >3 was much lower than for children with scores <3, P = .0001. Correlations between FLACC and Visual Analog Scale observer pain and distress were good (r = .74 and r = .89, respectively). This study supports the reliability and sensitivity of the FLACC scale for procedural pain assessment. However, the circumstances of procedures interfered with application of the scale and the findings question the capacity of the scale to differentiate between pain- and nonpain-related distress.

PERSPECTIVE

This article provides evidence that the FLACC scale is reliable and sensitive to pain for procedural pain assessment. Concerns remain about specificity and scale design. Identification of a scale valid for this purpose is needed to provide a platform for improved procedural pain management in infants and young children.

The Psychometric Properties of the MBPS Scale Used to Assess Procedural Pain

The Modified Behavioral Pain Scale (MBPS) was designed to assess procedural pain in infants and is considered valid for assessing immunization pain. The aim of this study was to assess the practical and psychometric properties of the MBPS when applied to other commonly performed procedures. Twenty-six clinicians independently applied the MBPS scale to segments of video collected from 100 infants and children aged 6 to 42 months undergoing 1 of 4 procedures in the emergency department. Positive correlation between MBPS and Visual Analogue Scale observer applied (VASobs) pain (r = .74) was shown and inter- and intrarater reliability coefficients were high (.87 and .89, respectively). Construct validity was shown by scale responsiveness to painful stimuli (4.6 times increase in scores across phases) and the capacity of the scale to distinguish between painful versus nonpainful procedures (P < .001). However, mean baseline scores for procedures were not 0 (likely a function of item descriptors for a "0" score) and the mean difference increased across phases for children with baseline scores >3, which was much lower than for children with scores <3 (P = .0001). Finally, 28% of scores changed after the second viewing of a video segment. The MBPS appears reliable and sensitive to procedural pain when applied by clinicians. Results question the capacity of the scale to differentiate between pain- and nonpain-related distress, the feasibility of this scale, and the appropriateness of item descriptors for medical procedures.

PERSPECTIVE

This article presents the psychometric and practical properties of the MBPS applied to assess procedural pain. Identification of a suitable scale for this purpose will support improved pain management in infants and young children who undergo painful procedures.

Projector-based virtual reality dome environment for procedural pain and anxiety in young children with burn injuries: a pilot study

BACKGROUND

Virtual reality (VR) is a non-pharmacological method to distract from pain during painful procedures. However, it was never tested in young children with burn injuries undergoing wound care.

AIM

We aimed to assess the feasibility and acceptability of the study process and the use of VR for procedural pain management.

METHODS

From June 2016 to January 2017, we recruited children from 2 months to 10 years of age with burn injuries requiring a hydrotherapy session in a pediatric university teaching hospital in Montreal. Each child received the projector-based VR intervention in addition to the standard pharmacological treatment. Data on intervention and study feasibility and acceptability in addition to measures on pain (Face, Legs, Activity, Cry, Consolability scale), baseline (Modified Smith Scale) and procedural (Procedure Behavior Check List) anxiety, comfort (OCCEB-BECCO [behavioral observational scale of comfort level for child burn victims]), and sedation (Ramsay Sedation Scale) were collected before, during, and after the procedure. Data analyses included descriptive and non-parametric inferential statistics.

RESULTS

We recruited 15 children with a mean age of 2.2±2.1 years and a mean total body surface area of 5% (±4). Mean pain score during the procedure was low (2.9/10, ±3), as was the discomfort level (2.9/10, ±2.8). Most children were cooperative, oriented, and calm. Assessing anxiety was not feasible with our sample of participants. The prototype did not interfere with the procedure and was considered useful for procedural pain management by most health care professionals.

CONCLUSION

The projector-based VR is a feasible and acceptable intervention for procedural pain management in young children with burn injuries. A larger trial with a control group is required to assess its efficacy.

Can live music therapy reduce distress and pain in children with burns after wound care procedures? A randomized controlled trial

OBJECTIVE

Burn wound care procedures are very painful and lead to distress. Live music therapy has shown beneficial effects on distress and pain in specific pediatric patient populations. In this study we measured whether live music therapy has beneficial effects in terms of less distress and pain in children with burns after wound care procedures.

METHODS

This randomized assessor-blinded controlled trial (RCT) took place at the burns unit of the Red Cross War Memorial Children's Hospital, Cape Town, South Africa. It included newly admitted inpatients between the ages of 0 and 13 years undergoing their first or second wound care procedures. Excluded were children with a hearing impairment or low level of consciousness. The intervention group received one live music therapy session directly after wound care in addition to standard care. The control group received standard care only. The primary outcome was distress measured with the Observational Scale of Behavioral Distress-revised (OSBD-r). The secondary outcome was pain measured with the COMFORT-behavioral scale (COMFORT-B). In addition, in children older than 5 years self-reported distress with the validated Wong-Baker scale (FACES) and pain with the Faces Pain Scale-Revised (FPS-R) were measured. Patients in both groups were videotaped for three minutes before wound care; during the music therapy or the control condition; and for two minutes thereafter. Two researchers, blinded to the study condition, independently scored the OSBD-r and the COMFORT-B from the video footage before and after music therapy.

RESULTS

We included 135 patients, median age 22.6 months (IQR 15.4-40.7 months). Change scores did not significantly differ between the intervention and the control groups for either distress (p=0.53; d=0.11; 95% CI -0.23 to 0.45) or pain (p=0.99; d=0.04; 95% CI -0.30 to 0.38). Self-reported distress in a small group of children (n=18) older than 5 years indicated a significant reduction in distress after live music therapy (p=0.05).

CONCLUSIONS

Live music therapy was not found effective in reducing distress and pain in young children after burn wound care. Older children might be more responsive to this intervention.

A prospective audit of pain profiles following general and urological surgery in children

BACKGROUND

Postoperative pain is frequently undertreated in children both in hospital and at home following discharge. Pain has both short- and long-term consequences for children, their families, and the healthcare system. A greater understanding of procedure-specific postoperative pain trajectories is required to improve pain management.

AIM

To determine the duration and severity of acute postoperative pain experienced by children undergoing 8 different general and urological procedures (primary outcomes). Behavioral disturbance rates, nausea and vomiting scores, and parental satisfaction were also examined during the follow-up period (secondary outcomes).

METHOD

Families of children (0-18 years) undergoing common general and urological procedures were invited to enroll in the study. Children's pain scores, measured using a parental proxy 0-10 numerical rating scale, were collected by telephone interview until pain was resolved. Analgesia prescribed and given, behavioral disturbance, nausea and vomiting scores, the method of medication education communication, and parental satisfaction were also measured.

RESULTS

Of 360 patients recruited, 326 complete datasets were available. Patients underwent laparoscopic appendicectomy (57), open appendicectomy (19), circumcision (50), cystoscopy (52), hypospadias repair (22), inguinal hernia repair (51), orchidopexy (51), or umbilical hernia repair (24). Postoperative pain peaked on the day of or the day after surgery in all groups, and decreased over time. Pain lasted a median duration of 5 postoperative days following open appendicectomy, and 0-2 postoperative days for other procedures. Behavioral disturbance rates closely followed pain scores. Analgesia administration at home varied widely between and within groups.

CONCLUSION

Pain management was inadequate in most of the groups studied, particularly after appendicectomy or umbilical hernia repair, with most children experiencing at least moderate pain on the day of and day after surgery. There was a need for a standardized management, with increased dual analgesia prescribing, to ensure that children receive adequate postoperative analgesia in hospital and at home.

Randomized clinical trial of immersive virtual reality tour of the operating theatre in children before anaesthesia

Background

A virtual reality (VR) tour of the operating theatre before anaesthesia could provide a realistic experience for children. This study was designed to determine whether a preoperative VR tour could reduce preoperative anxiety in children.

Methods

Children scheduled for elective surgery under general anaesthesia were randomized into a control or VR group. The control group received conventional information regarding anaesthesia and surgery. The VR group watched a 4-min video showing Pororo, the famous little penguin, visiting the operating theatre and explaining what is in it. The main outcome was preoperative anxiety, assessed using the modified Yale Preoperative Anxiety Scale (m-YPAS) before entering the operating theatre. Secondary outcomes included induction compliance checklist (ICC) and procedural behaviour rating scale (PBRS) scores during anaesthesia.

Results

A total of 69 children were included in the analysis, 35 in the control group and 34 in the VR group. Demographic data and induction time were similar in the two groups. Children in the VR group had a significantly lower m-YPAS score than those in the control group (median 31·7 (i.q.r. 23·3–37·9) and 51·7 (28·3–63·3) respectively; P &lt; 0·001). During anaesthesia, the VR group had lower ICC and PBRS scores than the control group.

Conclusion

This preoperative VR tour of the operating theatre was effective in alleviating preoperative anxiety and increasing compliance during induction of anaesthesia in children undergoing elective surgery. Registration number: UMIN000025232 (http://www.umin.ac.jp/ctr).

Effect of cryotherapy on pain management at the puncture site of arteriovenous fistula among children undergoing hemodialysis

OBJECTIVE

To evaluate the effectiveness of cryotherapy in managing the pain at the puncture site of Arterio-Venous Fistula (AVF) among children undergoing maintenance hemodialysis (HD).

METHODS

A one-group pre-post quasi-experiment was performed in two HD centers affiliated with Cairo University. The experiment involved 40 children with AVF undergoing HD. Before puncturing, cryotherapy was applied using 2 cm-3 cm pieces of frozen distilled water in a plastic bag. Pain was assessed subjectively and objectively in two dialysis sessions before and after cryotherapy. A part from a physiological assessment of vital signs, pain was assessed using the Wong-Baker Faces Pain and the Observed Pain Behavior rating scales. All research ethics were applied.

RESULTS

HD had a median duration of four years, while cryotherapy had a median application time of 8.8 min. The Wong-Baker Faces Pain score and almost all observed pain behaviors significantly decreased after cryotherapy. Significant improvements were observed in respiratory rate before and after needle puncture and in oxygen saturation after needle puncture. A lower skin dryness was observed after cryotherapy (12.5%) than before cryotherapy (52.5%; p < 0.001).

CONCLUSIONS

Cryotherapy can effectively reduce the venipuncture pain among children with AVF undergoing maintenance HD. However, the confounding effects of distraction and the non-randomized design used must be both considered when interpreting the findings. This study recommends the use of cryotherapy in managing needle puncture pain. Further research must adopt a randomized trial design with a placebo to support further the benefits of this procedure.

Pain after discharge following head and neck surgery in children

BACKGROUND

It is well established that children experience significant pain for a considerable period following adenotonsillectomy. Less is known, however, about pain following other common head and neck operations.

AIM

The aim of this study was to describe the severity and duration of postoperative pain experienced by children undergoing elective head and neck procedures (primary outcomes). Behavioral disturbance, nausea and vomiting, parental satisfaction, and medical reattendance rates were also measured (secondary outcomes).

METHOD

Parents of children (0-18 years) undergoing common head and neck operations were invited to participate. Pain scores on the day of surgery and each day post discharge were collected via multiple telephone interviews. Data collected included pain levels, analgesia prescribed and given, behavioral disturbance rates, and nausea and vomiting scores. Follow-up was continued until pain resolved.

RESULTS

Two hundred and fifty-one patients were analyzed (50 adenoidectomy, 51 adenotonsillectomy, 19 myringoplasty, 52 myringotomy, 43 strabismus, and 36 tongue tie divisions). On the day of surgery myringoplasty, strabismus surgery, and adenotonsillectomy patients on average had moderate pain, whereas adenoidectomy, tongue tie, and myringotomy patients had mild pain. Adenotonsillectomy patients continued to have moderate pain for several days with pain lasting on average 9 days. From day 1 postoperatively mild pain was experienced in the other surgical groups with the average duration of pain varying from 1 to 3 days depending on the surgery performed. Frequency of behavioral issues closely followed pain scores for each group. Analgesic prescribing and regimes at home varied widely, both within and between the different surgical groups. Rates of nausea and vomiting following discharge were low in all groups. The overall unplanned medical reattendance rate was 16%.

CONCLUSION

Adenotonsillectomy patients represent the biggest challenge in postoperative pain management of the head and neck surgeries evaluated. The low rates of pain, nausea, and vomiting reported in the days following surgery for the other procedures suggests that children can be cared for at home with simple analgesia. Discharge information and analgesia prescribing on discharge should be tailored to the operation performed.
