An episode of malignant hyperthermia occurring in a two-year-old child undergoing cardiac surgery is re-ported. The coincidental usage of hypothermic cardio-pulmonary bypass obscured the classical presenting signs and symptoms of the syndrome. Once the clinical diagnosis was confirmed, rapid reversal was achieved with the administration ofdantrolene sodium.

Key words

hyperthermia: malignant surgery: cardiac 


Un épisode d’hyperthermie maligne ayant survenu chez un enfant de 2 ans subissant une chirurgie cardiaque est rapporté. L’utilisation de l’hypothermie lors de la circu-lation extra-corporelle a obscursi les signes classiques ainsi que les symptômes annonçants ce syndrome. Lorsque le diagnostic clinique a ete confirme, le retablis-sement rapide a été acquis avec l’administration du dantrolène.
