Hyperthermia in a Chow Chow under general anaesthesia for magnetic resonance imaging.

A 5‐year 7‐month‐old, entire, male Chow Chow presented with paraparesis and ataxia due to a previously diagnosed T11–T12 spinal diverticulum. Due to the progression of clinical signs, magnetic resonance imaging was indicated to reassess the lesion. Preoperative rectal temperature was unable to be assessed due to temperament; however, it was likely the patient would be hyperthermic as it had been hyperthermic (40.6°C) under general anaesthesia 4 months earlier. Consequently, measures were taken to attempt to reduce body temperature before general anaesthesia. While under general anaesthesia for imaging, the patient was confirmed to be markedly hyperthermic. This report details the management of a patient with hyperthermia under general anaesthesia. The patient was gradually cooled before recovery from anaesthesia. Once recovered from anaesthesia and normothermic, the patient was discharged home the same day. Follow‐up confirmed no adverse effects. [ABSTRACT FROM AUTHOR]
