A healthy 5-year-old boy presented for arch bar placement under general anesthesia in an operating room in a dental school. The patient had previously undergone general anesthesia without complication, and no family history of anesthetic problems were reported. Halothane mask induction, intravenous catheter placement, and nasal intubation proceeded uneventfully without the aid of a muscle relaxant. Halfway through the procedure, signs and symptoms of malignant hyperthermia, including muscle rigidity, hypercarbia, tachypnea, and tachycardia were noted. Immediate treatment, including discontinuation of the triggering agent, dantrolene administration, and cooling measures were applied, and once stable, the child was transferred to Columbus Children's Hospital for further management. The patient experienced no postoperative complications. Further discussion regarding the pathophysiology and management of malignant hyperthermia is provided.

Malignant hyperthermia (MH) is an inherited, pharmacogenetic disorder of the skeletal muscle, characterized by dangerous hypermetabolic state after anesthesia with succinylcholine and/ or volatile halogenated anesthetic agents, clinically manifested as hyperpyrexia and related complications like tachycardia, tachypnea, increased carbon dioxide production, increased oxygen consumption, acidosis, rigid muscles, rhabdomyolysis and disseminated intravascular coagulation (DIC). Here we present a series of three cases of MH, admitted in our hospital in a span of 8 months for three different operative procedures to be done under general anesthesia (cleft lip repair, Duhamel's operation for Hirschsprung's disease and surgical repair of development dysplasia of hip), who developed probable hyperthermia owing to Halothane being used as an anesthetic agent.
