A Rare Presentation of Malignant Hyperthermia in a Patient With Poliomyelitis

Malignant hyperthermia (MH) is a rare hypermetabolic response to halogenated anesthetic gases or succinylcholine. We presented a case of malignant hyperthermia in a 39-year-old male with a past medical history significant for poliomyelitis, who had been exposed to anesthetic agents multiple times in the past. The patient presented with MH crisis about 4 h after surgery, with pre operative exposure to succinylcholine. Seventy percent of MH cases are familial ones and sporadic cases are rare. This case report creates awareness of the diagnosis of MH in patients without family history of the disorder and with delayed symptom onset. Studies are lacking on the pathophysiology of MH in patients with neuromuscular disorders since these patients might have atypical presentation.
