Malignant hyperthermia

Malignant hyperthermia, although an uncommon condition, has dramatic consequences when it occurs. The exact cause of MH is unknown but it is triggered by agents such as suxamethonium and volatile anaesthetic agents, especially Halothane. The condition can occur at anytime during the perioperative period and practitioners need to be vigilant towards its signs and symptoms as well as fully aware of the need for prompt action should it occur. The management of MH also includes identifying those at risk and taking measures to minimise these risks during anaesthesia.
