Malignant hyperthermia is a potentially fatal condition, in which genetically predisposed individuals develop a hypermetabolic reaction to potent inhalation anaesthetics or succinylcholine. Because of the rarity of malignant hyperthermia and ethical limitations, there is no evidence from interventional trials to inform the optimal perioperative management of patients known or suspected with malignant hyperthermia who present for surgery. Furthermore, as the concentrations of residual volatile anaesthetics that might trigger a malignant hyperthermia crisis are unknown and manufacturers' instructions differ considerably, there are uncertainties about how individual anaesthetic machines or workstations need to be prepared to avoid inadvertent exposure of susceptible patients to trigger anaesthetic drugs.

However, malignant hyperthermia crises are rare, and there may be administrative pressures to limit the amount of dantrolene stocked or, in some countries, not to stock dantrolene at all. There are no published guidelines to support anaesthetic departments in their effort to ensure availability of sufficient dantrolene for the management of malignant hyperthermia crises.

This article gives a short description of the investigation of MH susceptibility in Denmark and an introduction to the new guidelines in Danish.

Malignant hyperthermia is triggered by volatile anesthetics and succinylcholine. In this article the pathophysiology of malignant hyperthermia, its signs, symptoms and treatment as well as safe anesthetic agents for individuals susceptible to malignant hyperthermia are discussed.
