A case of severe muscular rigidity in a premature male infant born by Caesarean Section under general anaesthesia is described. A probable diagnosis of malignant hyperthermia was supported by the clinical symptoms of muscular rigidity and cyanosis, a creatinine phosphokinase of 24,630 I.U. (Normal 0--100) and a urinary myoglobin of 248 mg/l (normal 6--35). The muscle tone and laboratory values slowly returned to normal over a period of days. Anaesthetic management for a ventriculoperitoneal shunt performed at seven weeks of age included pre and postoperative treatment with dantrolene. No crisis occurred at this time. The parents, who have normal CPK and a negative family history, were advised to treat the child as if he had malignant hyperthermia until such time as a definitive diagnosis can be made.

A case of malignant hyperpyrexia (MH) occurring in a patient undergoing orthognathic surgery is reported which resulted in the procedure being abandoned prior to completion. The oral surgeon's role in recognising the early clinical signs of masseteric spasm and central cyanosis is highlighted. The case shows that with proper investigation and management the MH susceptible patient was able to have a second anaesthetic with safety to complete the surgery.

A 13-year-old boy presenting for correction of bat ears was anaesthetised with thiopentone and suxamethonium, the administration of which was followed by jaw spasm, poor peripheral perfusion (without cyanosis) and marked tachycardia. The procedure was abandoned, dantrolene and Ringer lactate IL were given intravenously and the patient regained consciousness 1 h later. Levels of serum myoglobin, urinary myoglobin and creatine kinase were followed until they returned to normal. Despite a peak serum myoglobin of 58.000 micrograms.l-1 and peak urinary level of 446,000 micrograms.l-1, no renal impairment occurred. Subsequent testing for susceptibility to malignant hyperthermia proved positive for the patient and four other members of the family.
