It is said to be to a defective calcium channel located in the sarcoplasmic reticulum membrane called the ryanodine receptor.\ Presented is a case of a 55 year old male who underwent direct laryngoscopy under general anesthesia in which the classic signs of MH were observed such as hyperthermia to a marked degree, tachycardia, tachypnea, increased end-tidal carbon-dioxide, acidosis, muscle rigidity and rhaabdomyolysis. These pathophysiologic changes of MH could lead to life-threatening complications like renal failure from rhabdomyolysis and disseminated intravascular coagulation (DIC) which were seen in our patient, hence the demise despite resuscitative measures and treatment ER -
