WebMalignant Hyperthermia (MH) is an acute pharmacogenetic (autosomal dominant) disorder, which develops during or immediately after the application of general anaesthesia involving volatile agents and/or depolarising muscle relaxants. The disorder is as a result of a defect in calcium channel regulation in the muscle cell. WebThe main goal of treatment is to normalize metabolism, prevent or reverse hyperthermia, and prevent rhabdomyolysis. The mainstay of treatment includes discontinuation of the trigger agent, dantrolene therapy, and restoration of a normal core temperature. Hopkins PM, Girard T, Dalay S, et al.
