Anesthetic malignant hyperthermia (HM) is a pharmacogenetic myopathy of anesthesia. It is induced by halogenated volatile anaesthetic agents and/or depolarizing curare (succinylcholine), in individuals with a familial muscle abnormality, transmitted in an autosomal dominant manner.

We report a probable case of fulminant HM linked to isoflurane.

The case was a 46-year-old patient with no particular medical history and had previously received uneventful general anaesthesia. Classified ASA 1 after a CPA, she was admitted to the operating room for a regulated thyroidectomy. General anaesthesia with intubation was performed with propofol and vecuronium during induction and anaesthetic maintenance with isoflurane. About 90 minutes after induction a symptomatological triad sets in: increased ETCO2, generalized muscle rigidity and hyperthermia above 40°C. The probable hypothesis of a crisis of HM is then quickly evoked. In the absence of dantrolene as a specific treatment for HM, discontinuation of isoflurane and resuscitation measures were initiated. The consequences are marked by refractory metabolic acidosis and severe hypocalcaemia responsible for cardiac arrhythmia after several episodes of cardiac arrests resuscitated without success.

Due to a limited technical platform, confirmation of the diagnosis of anaesthetic HM in our patient could not be possible. Notamment the realization of a post-mortem muscle biopsy which would have allowed diagnostic tests of pathological contracture.

Nevertheless, the hypothesis of malignant hyperthermia of anesthesia seemed more than likely in our patient. Despite its rarity, the potentially lethal nature of this pharmacogenetic subclinical myopathy justifies that any anesthesiologist knows the elements of diagnosis and treatment of the crisis and knows how to recognize the subjects at risk to perform safe anesthesia in these patients.
