Abstract
Currently, evaluation of equine anaesthetic risk is largely based on the American Society of Anaesthesiologists physical status classification system. However, a recent survey of experienced equine anaesthetists indicated that anaesthetic risk could also be based on patient factors and factors associated with the intended procedure including positioning, anticipated duration and ability or desire to assist recovery. Furthermore, additional anaesthesia-related risk factors have been identified through clinical research, which may warrant consideration when assessing individual patient risk.
