Twenty years later: a single-centre, repeat retrospective analysis of equine perioperative mortality and investigation of recovery quality.

Objectives: To determine the mortality rates associated with equine anaesthesia for elective and emergency (colic and non-colic) cases in one equine, university teaching hospital and to investigate the effect of several horse- and anaesthetic-related variables on anaesthetic recovery quality.

Study Design: Retrospective data analysis.

Animals Or Animal Population: In total, 1416 horses undergoing anaesthesia between May 2010 and December 2013.
