During a surgical procedure, in a pig, under general anaesthesia with sevoflurane, the animal developed malignant hyperthermia. Malignant hyperthermia was expressed only by a progressive increase of rectal temperature without early symptoms from the cardiopulmonary system. The delayed onset of the malignant hyperthermia may be due to the co-administration of a number of drugs at the pre-anaesthetic phase as well as during the surgical procedure.

Key words: malignant hyperthermia, pig, sevoflurane, anaesthesia
