Long-term efficacy and safety of repeated botulinum toxin a applications based on function and anesthesia type in...

Area of Science:

• Pediatric Neurology
• Rehabilitation Medicine
• Anesthesiology

Background:

• Botulinum toxin A (BoNT-A) injections are used to manage spasticity in pediatric patients.
• Repeated applications are often necessary for sustained therapeutic effects.
• Anesthesia choice impacts patient recovery and procedural efficiency.

Purpose of the Study:

• To assess motor development following repeated Botulinum toxin A (BoNT-A) applications in pediatric patients.
• To compare the safety and efficacy of three anesthesia methods (sedation analgesia, laryngeal mask anesthesia, inhalation mask) in these procedures.

Main Methods:

• Evaluation of 75 children with at least three consecutive BoNT-A applications (320 procedures total).
• Motor development assessed using the Gross Motor Function Classification System (GMFCS).
• Comparison of anesthesia types based on sedation, procedure, recovery, and operating room time.

Main Results:

• Significant motor development observed in 80% of patients post-BoNT-A treatment.
• Shorter recovery times noted with sedation analgesia during the first three procedures.
• No significant difference in recovery time among anesthesia methods after the fourth procedure.
• Recovery time increased with six or more procedures, irrespective of anesthesia type.

Conclusions:

• Repeated BoNT-A applications are safe and effective for improving motor function in children.
• Sedation analgesia facilitates quicker recovery for the initial treatments.
• Increased number of BoNT-A applications correlates with longer recovery times, highlighting the need for careful anesthetic management.
