Malignant hyperthermia (MH) is a hypermetabolic response to succinylcholine or inhaled volatile gases administered during anesthesia and is caused by an autosomal dominant mutation of RYR1 or CACNA1S genes which affect how calcium channels function. The uncontrolled, unopposed calcium release and excitation-contraction coupling results in sustained skeletal muscle contraction resulting in muscle rigidity, hyperthermia, hypercapnia, hypertension, and tachycardia among other less common clinical features. The sequelae of an MH crisis include renal failure, rhabdomyolysis, hyperkalemia, metabolic disturbance and left untreated will result in mortality. All clinicians involved in peri-operative care both in-hospital and out of hospital must be cognizant of …

Malignant Hyperthermia as defined by the International Classification of Diseases is a rare but progressive, and life-threatening hyperthermic reaction in response to a triggering agent such as general anesthetic gases or the depolarizing neuromuscular blocking agent Succinylcholine (Hopkins et. al., 2020). MalignantHyperthymia is a genetic disorder of the skeletal muscle, that leads to continuous muscle contraction and the inability to relax skeletal muscle (Haili and Weant, 2021). Signs and symptoms can vary from patient to patient and can be masked by anesthesia, but the classical signs include an increase in end-tidal CO2, increased heart rate, and a rapid increase in …
