WebWHAT IS MALIGNANT HYPERTHERMIA (MH)? A potentially lethal hypermetabolic complication of a rare inherited skeletal muscle disorder Caused by either increased myoplasmic calcium release or decreased calcium uptake with muscle contraction. A severe reaction that occurs with anesthetic medications, and muscle relaxants, such as Malignant hyperthermia is a disorder that can be considered a gene–environment interaction. In most people with malignant hyperthermia susceptibility, they have few or no symptoms unless they are exposed to a triggering agent. The most common triggering agents are volatile anesthetic gases, such as halothane, sevoflurane, desflurane, isoflurane, enflurane or the depolarizing muscle relaxants suxamethonium and decamethonium used primarily in general anesthesia. In rare cases…
