An unusual presentation of postoperative malignant hyperthermia

Abstract

INTRODUCTION

Malignant hyperthermia (MH) is a genetically determined life-threatening clinical syndrome of hypermetabolism involving the skeletal muscle. It is triggered in susceptible people after being exposed to certain inhalational anesthetic agents and the muscle relaxant suxamethonium. Clinical picture ranges from muscle rigidity to raging temperature with variation in time of onset. We present a case of six months old child who underwent cleft lip surgery under general anesthesia (GA). The course of anesthesia was uneventful but the baby’s body temperature rapidly spiked during recovery. The temperature was brought under control with inj. dantroline. We could not find similar case report in the published literature.
