malignant hyperthermia

Summary
Synonym
  • anesthesia related hyperthermia
  • malignant hyperpyrexia due to anesthesia
Definition
A muscle tissue disease that is characterized by a drastic and uncontrolled increase in skeletal muscle oxidative metabolism, which overwhelms the body's capacity to supply oxygen, remove carbon dioxide, and regulate body temperature and that has_material_basis_in heterozygous mutation in the ryanodine receptor gene (RYR1) on chromosome 19q13. Manifestations of malignant hyperthermia (MH) are precipitated by certain volatile anesthetics (i.e., halothane, isoflurane, sevoflurane, desflurane, enflurane), either alone or in conjunction with a depolarizing muscle relaxant (specifically, succinylcholine).
