Halothane and malignant hyperthermia
WebMalignant hyperthermia is a heterogeneous disorder of skeletal muscle with variable clinical penetrance. •. Affected individuals develop a hypermetabolic syndrome on exposure to triggering agents (succinylcholine, volatile halogenated agents). •. The current diagnostic test is the caffeine-halothane contracture test. •. WebMalignant hyperthermia (MH) is a pharmacogenetic disease in man and animals. It primarily involves skeletal muscle tissue, but other tissues might be affected to a lesser degree. Calcium homeostasis in muscle cells is upset in susceptible individuals, so that various agents and circumstances can inc …
