Pain Management Strategies for Botulinum Toxin Type A Injections in Children: A Comprehensive National Survey and Procedural Protocol

INTRODUCTION

Botulinum toxin type A injections are a first-line treatment for spasticity in children. Our purpose is to delineate the national landscape concerning pain management for botulinum toxin type A injections in pediatric patients and to formulate a protocol grounded in current scientific evidence.

METHODS

We conducted a nationwide survey targeting physical medicine and rehabilitation specialists performing botulinum toxin type A injections for focal spasticity in children in Portugal. We conducted a literature review to compare the survey results with clinical guidelines, good practice manuals, and protocols published in the literature. Finally, we developed a procedural protocol for pain management in botulinum toxin procedures.

RESULTS

The survey was completed by 17 out of 18 identified specialists. All but one use some form of periprocedural analgesia. Five do not use any type of sedation. The majority do not assess pain during the procedures. From the reviewed articles, we obtained 23 articles, 19 of which provided data for detailed analysis.

CONCLUSIONS

A prevailing concern centers around pain management during botulinum toxin procedures in children. Nevertheless, a distinct absence of uniformity persists in appraising and managing procedure-related pain. This notion is further underscored by the marked heterogeneity and paucity of published literature within this realm. The systematic implementation of a procedural protocol thus becomes highly crucial.

Upper Limb Onabotulinumtoxin A Injections in Children Under 2 Years with Cerebral Palsy: A Retrospective Chart Review

Aim: To report on the safety of using Onabotulinumtoxin A (OnaA) in the upper limb(s) of children <2 years of age with cerebral palsy and to describe a proactive clinical model of care in the management of upper limb impairment in children with cerebral palsy. Methods and procedures: Retrospective chart audit of 65 infants aged 13-23 months (mean 18.69) who received upper limb OnaA injections. Administration procedures, trends in muscle selection, and adverse events were examined. Results: Adverse events were reported in 6 (4%) of the 65 children. Across the study period, muscles that control thumb and forearm movements were most commonly injected. The number of OnaA injections to subscapularis and flexor digitorum profundus increased over this period. Conclusions and implications: OnaA is a safe treatment option for the short-term management of focal upper limb muscle overactivity in children under 2 years of age with cerebral palsy. In line with existing evidence, OnaA should always be considered as an adjunct to evidence-based therapy.
