Does halothane cause malignant hyperthermia
Did you know?
WebThe muscle relaxant involved is usually succinylcholine; the inhalational anesthetic is most often halothane, but other anesthetics (eg, isoflurane, sevoflurane, desflurane) may also be involved. This drug combination causes a similar reaction in some patients with muscular dystrophy and myotonia. 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.
WebMalignant Hyperthermia (MH) has been a recognized complication of general anesthesia after the first case reports in the 1940's.
