[Risk and choice of anesthetics for patients with previous malignant hyperthermia syndrome]

Two cases of m.h. are reported. Various parameters--age of patients, predisposing situation and diseases, family history and enzyme changes, use of certain anaesthetics and myorelaxant--are examined and evaluated. Alternative anaesthesia techniques are suggested for patients presenting a family history of m.h. or who have manifested the syndrome on other occasions and who have to undergo further surgery.
