Recovery is an important part of the anesthetic episode, as monitoring is not as focused and complications can arise. This study investigated if there was a difference between the quality of recovery between induction with propofol or ketamine/diazepam. Dogs undergoing elective orthopedic procedures were induced with propofol (4 mg kg-1) or a combination of ketamine/diazepam (5/0.25 mg kg-1). Recoveries were video recorded and scored using a simple descriptive scale, numeric rating scale, and visual analog scale in real time. They were scored from the video by the live observer and three board-certified anesthesiologists. Two reviewers scored ketamine recoveries lower (better) than propofol ones. Averaging the scores given by all four video reviewers and only the anesthesiologists found lower scores for ketamine as well. Ketamine results in a statistically better recovery than propofol, but this difference may not be clinically significant.
