A 13 year old girl who had suffered from an abortive form of malignant hyperthermia during tonsillectomy eight years before was scheduled for orthopaedic surgery. Dantrolene sodium, 3 mg/kg orally, was given prophylactically the day before surgery; preanaesthetic medication consisted of Thalamonal, a fixed combination of droperidol and fentanyl; anaesthesia was induced with methohexitone and maintained as neurolept anaesthesia with fentanyl and droperidol; tubocurarine was administered for tracheal intubation and intraoperative neuromuscular blockade. Using this anaesthetic regimen no adverse reaction was triggered.

A series of 100 patients undergoing caesarean section was studied using ketamine 1.2 mg/kg as induction agent. Fifteen minutes prior to induction, atropine 0.25-0.5 mg and diazepam 1 mg was given intravenously as premedication. Anaesthesia was maintained with N2O:O2, FIO2 0.4. ⋯ There were no hallucinations in the recovery area. The mental condition of the mothers after the operation was acceptable. It is suggested that ketamine can be used not only on special indications but also as a routine method for induction of anaesthesia for caesarean section.
