Intra-operative post-induction hyperthermia, possibly malignant hyperthermia: Anesthetic implications, challenges and management.

Malignant Hyperthermia is a pharmacogenetic disorder. Classical manifestations comprise of tachycardia, increase in expired carbon dioxide levels, muscle rigidity, hyperthermia (>38.8°C) and unexpected acidosis. Here we report a case of 16-year-old female patient, ASA-I with chronic rhino-sinusitis and slight strabismus of the left eye posted for functional endoscopic sinus surgery, developing a rise in ETCO2 and temperature immediately following anesthesia induction. She was aggressively managed to an uneventful recovery. We present a case of intra-operative post-induction hyperthermia possibly MH, its anesthetic implications, challenges encountered and its management.
