Halothane malignant hyperthermia
WebMalignant Hyperthermia. Malignant Hyperthermia (MH) is a rare, inherited musculoskeletal syndrome that presents as a hypermetabolic reaction triggered by exposure to volatile anesthetic gases (e.g., desflurane, enflurane, halothane, sevoflurane) or the depolarizing muscle relaxant, succinylcholine. The signs of MH include muscle rigidity, … WebMalignant hyperthermia usually develops after a person receives a muscle relaxant (most often succinylcholine) along with an anesthetic gas (most often halothane) for surgery. Although malignant hyperthermia may develop after the first use of these drugs, people usually develop the condition only after about three exposures.

WebIntroduction. Malignant hyperthermia (MH) is a rare, but life-threatening, autosomal-dominant inherited disorder that may lead to metabolic crisis of skeletal muscle in susceptible individuals following exposure to triggering agents, such as volatile anesthetics or depolarizing muscle relaxants. 1 Functionally altered calcium release channels cause … The earliest signs may include: masseter muscle contracture following administration of succinylcholine, a rise in end-tidal carbon dioxide concentration (despite increased minute ventilation), unexplained tachycardia, and muscle rigidity. Despite the name, elevation of body temperature is often a late sign, but may appear early in severe cases. Respiratory acidosis is universally present and many patients have developed metabolic acidosis at the time of diagnos…
