Early Recognition and Treatment of Malignant Hyperthermia in Pediatric Patient during Bronchoscopy

الملخص EN

Malignant hyperthermia is a rare pharmacogenetic disorder triggered by depolarizing muscle relaxant and potent volatile anesthetic agents.

An MH crisis is an emergency and life-threatening event requiring early recognition and prompt management.

Dantrolene is the specific antagonist of MH.

The authors report the case of a 9-year-old boy who underwent an emergency bronchoscopy to remove a foreign body and developed masseter rigidity after succinylcholine and sevoflurane exposure.

The anesthesia team diagnosed an MH event, and the event was managed immediately with supportive treatment, dantrolene, being administered within 10 minutes.

The patient survived and had a good outcome without any complications.

We suggest that it is essential for anesthesia providers to recognize the need for intraoperative vigilance, prompt recognition, and treatment, and dantrolene sodium should be readily available in every hospital.
