Insights
Concurrent injections of botulinum toxin and phenol effectively manage spasticity in children with cerebral palsy (CP). This combined approach allows for multiple muscle injections, increasing treatment efficacy with infrequent adverse reactions.
Area of Science:
- Neurology
- Pediatrics
- Rehabilitation Medicine
Background:
- Spasticity in children with cerebral palsy (CP) and other neurologic conditions presents significant management challenges.
- Current treatments often require targeted interventions to improve motor function and quality of life.
Purpose of the Study:
- To detail the techniques and adverse events associated with combined botulinum toxin and phenol injections for pediatric spasticity.
- To evaluate the safety and efficacy of this dual-injection strategy.
Main Methods:
- A retrospective case series design was employed.
- Data from 68 pediatric patients undergoing 90 injection sessions at a tertiary care children's hospital were analyzed.
- Injections combined botulinum toxin (Botox or Myobloc) and phenol for spasticity management.
Main Results:
- A mean of 14 muscles were injected per session.
- Average phenol dosage was 9.5mL (0.6mL/kg).
- Adverse reactions were infrequent, including two cases of dysesthetic hand pain and one systemic reaction to Myobloc.
Conclusions:
- Concurrent botulinum toxin and phenol injections are a viable strategy for managing spasticity in pediatric patients.
- This combination therapy enables the treatment of numerous muscles, potentially at maximal recommended doses, with a low incidence of adverse events.
Objective:
To describe the specific techniques and adverse reactions of using concurrent, multiple injections of both botulinum toxin and phenol to manage spasticity in children with cerebral palsy (CP) and other neurologic conditions.
Design:
A retrospective case series.
Setting:
A tertiary care children's hospital.
Participants:
Consecutive patients (N=68) with spasticity related to CP or other neurologic conditions.
Intervention:
Ninety injection sessions combining botulinum toxin and phenol to manage spasticity.
Main Outcome Measure:
Documentation of adverse reactions.
Results:
The mean phenol dosage was 9.5mL at a mean of 0.6mL/kg per injection dose. The mean botulinum toxin type A (Botox) dose injected was 193U (12U/kg), and the mean of botulinum toxin type B (Myobloc) dose injected was 7750U (530U/kg). The mean number of muscles injected was 14. Adverse reactions are described but were infrequent. Dysesthetic hand pain occurred in 2 patients. One patient developed a systemic reaction to Myobloc.
Conclusions:
Using botulinum toxin and phenol injections allowed many muscles to be injected to manage spasticity in children with CP and other neurologic conditions. Using this combination allowed an increased number of injections at the maximal recommended dose.
