The revised FLACC score: Reliability and validation for pain assessment in children with cerebral palsy

Nalbuphine in Pediatric Emergence Agitation Following Cochlear Implantation: A Randomized Trial

Background

To investigate the effects of nalbuphine on emergency agitation (EA), which affects up to 80% of the children following otolaryngology procedures, in children undergoing cochlear implantation.

Methods

A prospective double-blinded randomized controlled clinical trial was conducted between November 2020 and October 2022. Eligible children, aged 6 months to 3 years old, were randomly assigned to either 0.1 mg/kg, 0.15 mg/kg, 0.2 mg/kg nalbuphine or 0.9% saline groups. EA was defined by the Pediatric Anesthesia Emergence Delirium (PAED) score ≥10. Extubation time, post-anesthesia care unit (PACU) length of stay, severe EA (PAED ≥ 15), peak PAED score, the Faces, Legs, Activity, Cry, and Consolability (FLACC) scale, Ramsay sedation score, and adverse events were also recorded.

Results

A total of 104 children were enrolled, with 26 children in each group. Nalbuphine significantly reduced the EA occurrence from 73.1% in the saline group to 38.5%, 30.8%, and 26.9% in the 0.1 mg/kg, 0.15 mg/kg, and 0.2 mg/kg nalbuphine groups, respectively (P < 0.001), without affecting the extubation time and PACU length of stay. More children (34.6%) in the 0.9% saline group experienced severe EA. Higher dose nalbuphine (0.15 mg/kg, 0.2 mg/kg) showed lower peak PAED score, better analgesia and sedation effect compared with 0.1 mg/kg nalbuphine and saline groups. However, 0.2mg/kg nalbuphine caused undesired over-sedation in two (7.7%) children. No other adverse events were reported.

Conclusion

Young children undergoing cochlear implantation surgery were at a high risk of EA and postoperative pain, while 0.2 mg/kg nalbuphine might be an ideal candidate for EA and pain prevention when used under close monitoring.

Effect of virtual reality combined with repetitive transcranial magnetic stimulation on musculoskeletal pain and motor development in children with spastic cerebral palsy: a protocol for a randomized controlled clinical trial

PURPOSE

This trial aims to investigate the efficacy and safety of virtual reality (VR) combined with repetitive transcranial magnetic stimulation (rTMS) for improving musculoskeletal pain and motor development in children with unilateral spastic cerebral palsy (CP).

METHODS

This study protocol is for a randomized controlled trial consisting of 2 treatment sessions (3 days/week for 4 weeks in each session, with a 1-week interval between sessions). We will recruit children aged 3-10 years with unilateral spastic CP (Gross Motor Function Classification System level I or II). Participants will be randomly divided into 3 groups: the VR + rTMS group (immersive VR intervention, rTMS and routine rehabilitation therapy), rTMS group (rTMS and routine rehabilitation therapy), and control group (sham rTMS and routine rehabilitation therapy). VR therapy will involve a daily 40-minute movement training session in a fully immersive environment. rTMS will be applied at 1 Hz over the primary motor cortex for 20 min on the contralateral side. The stimulation intensity will be set at 90% of the resting motor threshold, with 1200 pulses applied. A daily 60-minute routine rehabilitation therapy session including motor training and training in activities of daily living will be administered to all participants. The primary outcome will be pain intensity, assessed by the Revised Face, Legs, Activity, Cry, and Consolability Scale (R-FLACC). The secondary outcomes will include motor development, evaluated by the 66-item version of the Gross Motor Function Measure (GMFM-66) and Fine Motor Function Measure (FMFM); balance capacity, measured by the interactive balance system; activities of daily living; and quality of life, measured by the Barthel index and the Chinese version of the Cerebral Palsy Quality of Life scale for Children (C-CP QOL-Child). Safety will be monitored, and adverse events will be recorded during and after treatment.

DISCUSSION

Combined application of VR therapy and rTMS may reveal additive effects on pain management and motor development in children with spastic CP, but further high-quality research is needed. The results of this trial may indicate whether VR therapy combined with rTMS achieves a better analgesic effect and improves the motor development of children with spastic CP.

Analgesia Nociception Index (ANI) as a monitor of peri-operative nociception-antinociception balance in paediatric craniotomies: a prospective observational study

INTRODUCTION

Analgesia Nociception Index (ANI) as a monitor of peri-operative nociception-anti-nociception balance has not been studied in paediatric neurosurgery. The objectives were to study the correlation between ANI (Mdoloris Education system) and revised FLACC (r-FLACC) score for the prediction of acute postoperative pain in paediatric population undergoing elective craniotomies and to compare the changes in ANI values with heart rate (HR), mean arterial pressure (MAP) and surgical plethysmographic index (SPI) during various time points of intraoperative noxious stimulation and before and after opioid administration.

METHODS

This prospective observational pilot study included 14 patients between 2 and 12 years of age undergoing elective craniotomies. HR, MAP, SPI, ANI instantaneous (ANIi) and ANI mean (ANIm) values were recorded intraoperatively and before and after opioid administration. Postoperatively HR, MAP, ANIi and ANIm, and pain scores (r-FLACC scale) were recorded.

RESULTS

There was a statistically significant negative correlation between ANIi and ANIm with r-FLACC during the time course of PACU stay (r =  - 0.89, p < 0.001 and r =  - 0.88 and p < 0.001 respectively). Intraoperatively, in patients with ANIi values < 50, with additional fentanyl administration, there was an increasing trend in values beyond 50, which was statistically significant (p < 0.05) at 3, 4, 5 and 10 min. The trend in changes of SPI after opioid administration was not found to be significant for patients irrespective of the baseline SPI values.

CONCLUSION

The ANI is a reliable tool for objective assessment of acute postoperative pain as assessed by r-FLACC in children undergoing craniotomies for intracranial lesions. It may be used as a guide to nociception-antinociception balance during the peri-operative period in this population.

Lumbar Plexus Nerve Blocks for Perioperative Pain Management in Cerebral Palsy Patients Undergoing Hip Reconstruction: More Effective Than General Anesthesia and Epidurals

BACKGROUND

Hip reconstruction in patients with cerebral palsy (CP) is associated with. significant postoperative pain. However, adequate analgesia can be difficult to achieve. in this population due to spasticity, communication barriers, and postoperative. spasticity. Recently, multimodal pain management techniques such as epidurals and. regional nerve blocks have been described for postoperative pain control, but it is unclear if 1 technique is more beneficial. The purpose of this study was to compare the outcomes of different perioperative pain management techniques.

METHODS

This study is a retrospective review of a consecutive series of children with CP over a 5-year period at a single pediatric tertiary-care hospital who underwent hip reconstruction (proximal femoral osteotomy with or without a pelvic osteotomy). Patients were subdivided based on their anesthetic protocol into the following groups: general anesthesia alone (G), general anesthesia with an epidural (E), and general anesthesia with lumbar plexus block (LPB). Our primary outcome was cumulative postoperative narcotic consumption (converted to morphine equivalents). Secondary outcomes included length of stay (LOS), average postoperative heart rate, and pain scores. analysis of variance testing was utilized to compare differences between the groups.

RESULTS

Fifty-four patients who underwent hip reconstruction were included: 19 in the G group, 18 in the E group, and 17 in the LPB group. LOS was significantly higher in the E group compared with the G and LPB groups: F(2,51)=3.58, P=0.04. The average pain score was significantly lower in the LPB group compared with the others: F(2,51)=4.26, P=0.02. The average postoperative heart rate was significantly lower in the LPB group: F(2,51)=7.08, P<0.01. Postoperative narcotic consumption was significantly lower in the LPB group: F(2,51)=11.57, P<0.01.

CONCLUSION

The LPB patients required the least amount of narcotics compared with the other groups. This, combined with a lower perioperative heart rate and shorter LOS would suggest these patients experienced less pain over the time of their in-patient stay. In comparison to general anesthesia alone and epidural anesthesia, lumbar plexus nerve blocks are an effective pathway for postoperative pain control after hip reconstruction in a CP population.

Postsurgical pain assessment in children and adolescents with cerebral palsy: A scoping review

AIM

To investigate factors that influence the assessment of postoperative pain in children and adolescents with cerebral palsy (CP) and the tools available to determine pain intensity.

METHOD

The search was performed in January 2022 using six databases. Articles focused on paediatric patients with CP; we included instruments for postsurgical pain assessment in this population published in the last 11 years.

RESULTS

Eight of 441 studies were included. Males and females behave differently; their families can be called on to describe their pain responses. Seven instruments for pain assessment were identified: the Non-Communicating Children's Pain Checklist and its Postoperative Version; the Paediatric Pain Profile; the revised Face, Legs, Activity, Cry and Consolability (FLACC) pain scale; the Douleur Enfant San Salvador scale; the Pain Indicator for Communicatively Impaired Children; the University of Wisconsin Children's Hospital Pain Scale; and the Individualized Numeric Rating Scale.

INTERPRETATION

The revised FLACC pain scale is suited to postsurgical units because of its ease of use and the fact that parental collaboration is not required. More studies are needed to demonstrate the clinical utility of these scales in postsurgical units and the factors that influence pain assessment.

WHAT THIS PAPER ADDS

Families should be asked to collaborate when assessing pain in children and adolescents whenever possible. Larger studies that focus on the factors influencing pain assessment in this population are required.

Association of Pre-procedural Anxiety with Procedure-related Pain During Outpatient Pediatric Burn Care: A Pilot Study

The relationship between preprocedural anxiety and pain is not clear but has the potential to change the way pediatric patients need to be cared for prior to burn procedures. Using results from our recent randomized clinical trial among outpatient burn patients (n=90) age 6-17 years, the objective of this subsequent analysis was to assess whether preprocedural anxiety was associated with self-reported and researcher observed pain scores. Anxiety before the dressing change was assessed using an abbreviated State-Trait Anxiety Inventory for Children (range 6-21) and reported with 95% confidence intervals (CI). Self-reported pain was reported using a Visual Analog Scale (range 0-100) and observed pain was assessed using the Face, Legs, Activity, Cry, and Consolability-revised scale. Over half of patients (58.9%) reported mild anxiety (score <12) and about 5% of patients reported severe anxiety (score >16). Younger children (6-8 years) reported higher anxiety scores than older children (15-17 years), but the difference did not achieve statistical significance (mean=12.7, 95% CI: 11.5-13.9, p=0.09). Nonparametric spearman correlation indicated that anxiety score was significantly correlated with observed pain (p=0.01) and self-reported overall pain neared statistical significance (p=0.06). In the final logistic regression of reporting moderate-to-severe pain (pain score >30), the association between anxiety scores and self-reported overall moderate-to-severe pain was statistically significant (p=0.03) when adjusting for race, healing degree, and pain medication use within 6 hours prior to burn dressing care. This pilot study provides preliminary data showing that anxiety before outpatient pediatric burn dressing changes is significantly associated with self-reported overall moderate-to-severe pain.

Validation of the Indonesian Version of the Face, Legs, Activity, Cry, Consolability (FLACC) Scale in Postoperative Cleft Lip and/or Cleft Palate Patients

Background:

The face, leg, activity, cry, and consolability (FLACC) scale is a validated pain measurement instrument that is used on postoperative patients with limited verbal ability, including postoperative cleft lip and/or cleft palate patients.

Objective:

This research aimed to test the validity and reliability of the Indonesian version of the FLACC scale as a measuring instrument for pain intensity experienced by postoperative cleft lip and/or cleft palate patients.

Methods:

The procedure was initiated by a back-translation process of the FLACC. Once the back-translation process is completed, a calibration process of the field researchers was conducted. Twenty-eight participants that went through a cleft lip and/or cleft palate surgery at the Unpad Dental Hospital were then enrolled. Two calibrated field researchers measured the postoperative pain intensity in three different time points, shortly after the patients regained full consciousness (T0), four hours (T1), and eight hours after the first measurement (T2). The collected data were analysed by SPSS version 23. The Spearman correlation analysis was performed to test the validity, while a Cronbach’s alpha value was calculated to test the reliability.

Results:

Based on the results of the Spearman correlation analysis, the Indonesian version of the FLACC scale was considered to be valid as the r values of each sub-scale were all higher than the r table value (r value > 0.317). Reliability was marked by the obtained Cronbach’s alpha value of 0,875.

Conclusion:

The Indonesian version of the FLACC scale was considered to be valid and reliable to be used as a pain measurement tool in postoperative cleft lip and/or cleft palate patients.

Fascia Iliaca Pain Block Results in Lower Overall Opioid Usage and Shorter Hospital Stays than Epidural Anesthesia After Hip Reconstruction in Children With Cerebral Palsy

INTRODUCTION AND OBJECTIVE

Epidural anesthesia (EA) is often used for pain control in children with cerebral palsy (CP) who undergo hip reconstructions. The purpose of this study is to determine if preoperative fascia iliaca (FI) pain blocks would improve pain scores, decrease opioid use, and result in shorter hospital stays in comparison to the use of EA.

METHODS

This is a nonrandomized retrospective cohort study examining 60 consecutive patients with CP who underwent hip reconstruction utilizing either a fascia iliac compartment nerve block (FICNB) (N=37) or continuous lumbar epidural (N=22) from January 2017 to March 2019. Age at surgery was 8.5±4.6 years. We recorded age, weight, operating room (OR) time, FLACC (Face, Legs, Activity, Cry, Consolability scale) scores on postoperative days (PODs) 0, 1, 2, and 3, opioid doses, overall opioid (mg) used, and length of stay. We compared pain scores, opioid usage, OR time, and lengths of stay between our 2 patient groups.

RESULTS

Pain scores were similar between groups on POD #0, 2, and 3 but were statistically improved on POD #1 (1.8±1.3 vs. 3.1±1.4, P<0.001). Total number of opiod doses (7.9±4.4 vs. 10.7±2.3, P=0.004), total milligram given (18.3±11.8 vs. 24.7±12.3, P<0.05), and milligram per kilogram given (0.77±0.42 vs. 1.11 mg/kg±0.36 mg/kg, P=0.001) were less for the FI group versus the epidural group. The OR time (which includes time for blocks/epidurals) was lower in the FI group (4.6±1.2 vs. 5.7±1.1 h, P=0.0002). Overall hospital stays were lower in the FI group (3.4±1.5 vs. 4.1±1.0 d, P<0.05).

CONCLUSIONS

This study demonstrates that in the setting of hip reconstruction, patients that received preoperative FI blocks used a lower amount of opioids, required fewer rescue doses and ultimately had a shorter hospital length of stay than those undergoing EA.

Monopolar electrocautery tip vs plasma ablation in tonsillotomy: A randomized case-control study comparing outcomes in pediatric population

BACKGROUND

The objective of this study was to compare the low-priced monopolar electrocautery to the high-priced, worldwide used, plasma ablation in tonsillotomy among children aged between three and twelve years, suffering from obstructive breathing disorders (OBD), with respect to post-operative pain, bleeding and related morbidities.

METHODS

A randomized case-control study was conducted in the Eye and Ear Hospital International- Lebanon. 103 children aged between three and twelve years suffering from OBD secondary to tonsillar hypertrophy were randomly assigned into two groups. Post-operative pain was evaluated using age-adequate validated scales: "FLACC-R" (Face, Legs, Activity, Cry, Consolability-Revised) for children aged less than five years, and "Wong Baker faces" for older children. Additional post-operative outcomes were evaluated using Pain-PROM (Patient reported Pain-Related Outcome Measures) and TAHSI (Tonsil and Adenoid Health Status Instrument) scales.

RESULTS

Significantly, higher rates of patients who underwent tonsillotomy via plasma ablation technique used analgesics and had severe pain compared to the monopolar electrocautery group. A longer operative duration was significantly associated with higher pain scores, and the plasma ablation technique yielded significantly higher operative mean durations. 10 days post-operatively, a significantly higher percentage of children reported an overall high pain severity and more than expected overall pain when using the plasma ablation technique compared to the monopolar electrocautery one. Overall bleeding rates were similar. No difference was reported one month post-operatively.

CONCLUSION

When compared to plasma ablation, monopolar electrocautery, can provide the same efficiency in relieving OBD in healthy children, with equal overall bleeding rates, but significantly lower cost, operating time, pain scores and need for analgesics.

Lengthening of magnetically controlled growing rods caused minimal pain in 25 children: pain assessment with FPS-R, NRS, and r-FLACC

STUDY DESIGN

Descriptive case series.

OBJECTIVE

The aim of the study is to investigate the pain associated with magnetically controlled growing rod (MCGR) lengthening procedures. MCGRs have gained popularity because they offer non-surgical lengthening procedures in early-onset scoliosis (EOS) instead of semi-annual open surgery elongations with traditional growing rods. Many aspects of MCGR treatment have been investigated, but pain in conjunction with distraction is only sparsely described in the literature.

METHODS

Pain intensity was assessed in 25 EOS patients before, during and after MCGR lengthening procedures in an outpatient setup. They underwent at least two (range 2-16) lengthening procedures prior to this study. The pain intensity was estimated using patient-reported Faces Pain Scale (FPS-R), caregiver-reported pain numeric rating scale (NRS), and NRS and revised Face, Legs, Activity, Cry, Consolability scale (r-FLACC) by two medically trained observers. The inter-rater reliability and correlation between instruments were analyzed.

RESULTS

23 of 25 EOS patients (8- to 16-year old) with mixed etiology were able to self-report pain. The average pain intensity was mild: median 1 (range 0-6) on all four instruments on a 0-to-10 scale. Afterward, 22/25 patients (88%) were completely pain free and the remaining 3 patients had a pain score of 1. MCGR stalling (i.e. clunking) was encountered in 14/25 (56%) of the patients without impact on the pain intensity.

CONCLUSIONS

The average maximum pain intensities during the lengthening procedures were mild and pain ceased within few minutes. The inter-rater reliability was good to excellent for NRS and r-FLACC, and there were high correlations between all the four pain instruments, indicating high criterion validity.

LEVEL OF EVIDENCE

Level IV, case series.

Pain assessment in cerebral palsy: a systematic review of measurement properties and evaluation using the COSMIN checklist

Purpose: This systematic literature review aims to analyse the methodological quality of instruments available to assess pain in Cerebral Palsy (CP), according to the COSMIN guidelines and checklist.Materials and methods: Electronic literature searches were conducted in PubMed, ScienceDirect, Web of Science, PEdro, Scielo, Scopus and Academic Search Complete (EBSCO host) for articles on measurement properties of self-report, proxy or observational instruments.Results: A total of 14 instruments were identified. Of these, 8 were self-report instruments, 4 were observational instruments and 2 could be used both as self-report or proxy-report. The quality of the manuscripts was inadequate or doubtful in 45.5%, adequate in 15.9% and very good in 38.6% of the cases. No instrument was assessed for all the properties recommended by COSMIN. The quality of the evidence for the measurement properties of the pain assessment instruments ranged from very low to moderate.Conclusions: There is scarce and low-quality evidence on the measurement properties of instruments used to assess pain in individuals with cerebral palsy. Further research is needed designed in line with the COSMIN recommendations.Implications for rehabilitationThere is scarce and low-quality evidence on the measurement properties of instruments used to assess pain in individuals with cerebral palsy;Clinicians need to carefully choose instruments to assess pain in individuals with cerebral palsy as there is insufficient evidence on the quality of instruments;Self-report pain intensity scales may be a useful instrument for a subgroup of individuals with cerebral palsy.

An evaluation of the Danish version of the Pediatric Anesthesia Emergence Delirium scale

BACKGROUND

Emergence Delirium (ED) is a common complication from anesthesia. Although ED has a short duration, detection is important due to the risk that ED poses for post-operative complications in the child. The Pediatric Anesthesia Emergence Delirium (PAED) scale has been translated into Danish, but it has not yet been validated. The aim of this study was to investigate the inter-rater reliability, criterion validity, and responsiveness of the Danish version of the PAED scale as well as to determine the prevalence of ED.

METHOD

A sample of 100 post-operative children were enrolled and assessed with the PAED scale at pre-specified time intervals. Inter-rater reliability was assessed independently by 2 raters. For criterion validity, a clinical expert was chosen as the gold standard. Sensitivity and specificity were based on a comparison between the scoring of the raters and the gold standard. Responsiveness was assessed by comparing changes in scores. Prevalence was based on the PAED scale's cut-off level of ≥10 points.

RESULTS

A high level of agreement was found, with an intraclass correlation coefficient of 0.85-0.94. Few outliers appeared in the Bland-Altman plot. Sensitivity ranged from 70% to 86%, and the specificity of both raters against the gold standard was 100%. Changes in scores were indicative of responsiveness. Prevalence was 13.2%.

CONCLUSION

The Danish version of the PAED scale was found reliable and demonstrated high levels of sensitivity and specificity. In addition, it was possible to identify changes in scores over time. Prevalence was in line with existing literature.

Predictive factors of first dosage intravenous immunoglobulin-related adverse effects in children

BACKGROUND

Intravenous immunoglobulin (IVIG) therapy is used in the treatment of various diseases, and IVIG-related adverse effects (IVIG-AEs) vary from mild to severe. However, the mechanisms underlying IVIG-AEs and the potential predictive factors are not clear. This study investigated whether certain IVIG-AEs can be predicted before IVIG administration.

STUDY DESIGN AND METHODS

This retrospective cohort study at the Division of Neurology, Saitama Children's Medical Center included patients enrolled from 2008 to 2018 who were < 18 years old and received IVIG for the first time. IVIG-AEs were classified according to the Common Terminology Criteria for Adverse Events version 5.0.

RESULTS

A total of 104 patients fulfilled the inclusion criteria. The rate of IVIG-AEs was 37.5% (39/104). The most frequent IVIG-AEs were fever (41.0% [16/39]) and headache (38.5% [15/39]). AEs were below grade 2 in all except one patient and there were no grade 4 AEs. High serum total protein (TP) level was significantly related to the occurrence of IVIG-AEs (odds ratio, 14.8; 95% confidence interval, 2.4-90.5; P < 0.01). The optimal cutoff TP level was 6.7 g/dL. Although low WBC count and immunoglobulin G level may be predictive risk factors of IVIG-AEs, it was not confirmed in this study.

CONCLUSION

IVIG-AEs occurred in 37.5% of cases, and most were mild. TP was the best predictive risk factor of IVIG-AEs before IVIG administration. These results may aid in elucidating the mechanism underlying IVIG-AEs.

Measuring Musculoskeletal Pain in Infants, Children, and Adolescents

Synopsis Accurate, reliable, and timely assessment of pain is critical for effective management of musculoskeletal pain conditions. The assessment of pain in infants, children, and adolescents with and without cognitive impairment can be particularly challenging to clinicians for a number of reasons, including factors related to the consultation (eg, heterogeneous patient population, time constraints), the clinician (eg, awareness/knowledge of available pain scales), standardized assessment scales (eg, availability, psychometric properties, and application of each scale), the patient (eg, developmental stage, ability to communicate), and the context in which the interaction took place (eg, familiarity with the setting and physiological and psychological state). As a result, pain is frequently not assessed or measured during the consultation and, in many instances, underestimated and undertreated in this population. The purpose of this article is to provide clinicians with an overview of scales that may be used to measure pain in infants, children, and adolescents. Specifically, the paper reviews the various approaches to measure pain intensity; identifies factors that can influence the pain experience, expression, and assessment in infants, children, and adolescents; provides age-appropriate suggestions for measuring pain intensity in patients with and without cognitive impairment; and identifies ways to assess the impact of pain using multidimensional pain scales.
