General anaesthesia for a patient with progressive muscular dystrophy.

The case is reported of a four-year-old boy with progressive muscular dystrophy who underwent anal fistulectomy under neuroleptanaesthesia with Thalamonal. Recovery was uneventful. Anaesthetic problems associated with the disease include sudden death due to myocardial involvement and high postoperative mortality due to pulmonary infection. Mental retardation and ECG abnormalities may be present and acute postoperative gastric dilatation has been reported. Narcotics or minor tranquilizers and hyoscine are recommended for premedication. Light anaesthesia should be maintained throughout surgery and minimal doses of non-depolarizing muscle relaxants may be used if necessary. Suxamethonium chloride should be avoided because muscle damage and cardiac arrest might occur.
