Propofol anesthesia for a patient with progressive muscular dystrophy

摘要

We gave propofol anesthesia to a patient with limb-girdle type of progressive muscular dystrophy. A 42 year-old male was to have skin graft for third degree burn. His respiratory function test showed %VC of 73.6% and %FEV1.0 of 107.6%. Arterial blood gas data were within normal ranges. He was anesthetized with propofol, fentanyl, vecuronium and nitrous oxide. During position change, Wenckebach type of second degree AV block occurred. AV block returned to sinus rhythm easily by injection of ephedrine hydrochloride and atropine sulfate, and reduction of propofol infusion rate. There were no perioperative respiratory complications and no clinical manifestations of malignant hyperthermia. Propofol anesthesia is suitable for limb-girdle type of progressive muscular dystrophy, because of very little possibility of triggering malignant hyperthermia, rapid awaking, minimal residual effects of the respiratory system, and easiness in controlling anesthetic depth.
