Abstract

We report on a 25-year old ASA physical status I patient, who developed within 20 minutes a full-blown malignant hyperthermia (MH) in the context of a living donor liver transplantation after 180 minutes of uneventful anaesthesia. The only trigger substance applied was Sevoflurane. The patient had already received a short, uneventful anaesthesia with Isoflurane a couple of years ago. In the context of the special constellation an initial dose of Dantrolene of 10 mg/kg body weight was administered. The patient was stabilised within 30 minutes, and the enzyme levels remained low compared with other case reports. The post-operative in vitro caffeine halothane contracture testing confirmed that son and mother were susceptible to MH, contracture testing in the father was negative. All known triggers may cause life-threatening MH crisis - even after hours and after inconspicuous multiple exposures to known trigger substances. Therefore all trigger substances must be avoided in all patients susceptible to MH.
