Malignant hyperthermia in a cleft lip and palate patient: A case report.

Malignant hyperthermia (MH) is a rare genetic disorder that develops following exposure to volatile anaesthetic agents and depolarizing muscle relaxants. In this case report, a 10-year-old boy with cleft lip and palate underwent alveolar bone grafting for right cleft alveolus. In this surgery, the MH episode occurred approximately 2 h following induction of anaesthesia when the patient was noted to develop hypercapnia, tachycardia and hyperthermia. An MH crisis was declared. Immediate management included active cooling and intravenous dantrolene, to which the patient responded. In conclusion, early diagnosis and prompt action are very important in the successful management of MH. [ABSTRACT FROM AUTHOR]
