Malignant Hyperthermia, Eric Weberding

Malignant hyperthermia (MH) is an autosomal-dominant disorder that is inherited. The disturbance of calcium homeostasis associated with MH affects skeletal muscle (Schneiderbanger, Johannsen, Roewer, & Schuster, 2014). This hypermetabolic muscular disorder is triggered by exposure to depolarizing muscle relaxants such as succinylcholine or inhaled halogenated volatile anesthetics such as sevoflurane, halothane, desflurane, enflurane, and isoflurane (Stratman, Flynn, & Hatton, 2009). In susceptible individuals, this potentially lethal syndrome may cause hyperthermia, hypercapnia, muscular rigidity, hypoxemia, acidosis, tachycardia, and hyperkalemia (Schneiderbanger et al., 2014).
