Abstract
Among 111 ferrets, we classified and investigated them that had died of anesthesia-associated complications according to the American Society of Anesthesiologists Physical Status (ASA-PS). The mortality rate on anesthesia-associated complications of ferrets within 24 hours was 2.7% (ASA III: 2 ferrets, ASA IV: 1 ferret), and these ferrets were more than 4-year-old. In these ferrets, the main cause of death was cardiac arrest before/after surgery. Therefore, an age of 4 years or older and ASA grade of III or higher may significantly increase the risk of anesthesia-related death.
