Malignant hyperthermia

Hyperthermia - malignant; Hyperpyrexia - malignant; MH

Malignant hyperthermia (MH) is a disease that causes a fast rise in body temperature and severe muscle contractions when someone receives general anesthesia with one or more of the following drugs: halothane, isoflurane, sevoflurane, desflurane or succinylcholine. MH is a genetic disorder passed down through families.

Hyperthermia means high body temperature. Malignant hyperthermia is not the same as hyperthermia from other medical emergencies such as heat stroke or infection.
