Plain-English summary
A 7-week-old Vietnamese pot-bellied pig developed a dangerously high fever after being put under anesthesia for a routine spay surgery. About 90 minutes into the procedure, the pig started shivering and had a rapid heartbeat, with its temperature rising from normal to a peak of 41.5°C. The fever lasted for 18 hours, and the veterinary team treated it with cooling methods and a medication called dantrolene sodium. While malignant hyperthermia was suspected as the cause, no specific tests were done to confirm it. The case highlights the importance of monitoring temperature in pigs during and after anesthesia.

Abstract
Hyperthermia developed in a 7-week-old Vietnamese pot-bellied pig after isoflurane anesthesia for routine ovariohysterectomy. Shivering and a sudden increase in heart rate were noticed 90 minutes after anesthetic induction, both of which persisted throughout the remaining anesthetic period. Rectal temperature increased from 37 C immediately after anesthetic recovery to a peak of 41.5 C, and remained high for 18 hours. Treatment included external cooling and treatment with dantrolene sodium. Malignant hyperthermia was suspected to be the cause of the clinical signs in this pig, but specific tests to support this diagnosis were not performed. This report illustrates that hyperthermia may develop in this breed of swine during isoflurane anesthesia, and rectal temperature should be monitored during and after the anesthetic period.
