Neuromuscular blocking agents-45% alcohol, 4% to 6% aqueous phenol, lo
cal anesthetics, and botulinum A toxin-have been used for many years i
n the evaluation and management of spasticity and movement disorders i
n children with cerebral palsy. Recent reports suggest that longer-act
ing neuromuscular blocking agents may impact positively on the natural
history of dynamic deformity and improve health-related quality of Li
fe. This review includes the mechanism of action, techniques, indicati
ons, complications, and clinical outcomes associated with these agents
.
