Anaesthesia for caesarean section in spinal muscular atrophy type III.

We describe the conduct of general anaesthesia for a patient with spinal muscular atrophy Type III (Kugelberg-Welander disease) undergoing elective caesarean section. Apart from a delayed return of skeletal muscle power following non-depolarising neuromuscular blockade the procedure was uneventful. We found no previously published reports of general anaesthesia for caesarean section in this condition in the English language literature. We review the available literature and discuss the potential anaesthetic problems in the management of obstetric patients with this degenerative neuromuscular disorder.
