Dogs that had cholecystectomy had longer anesthesia durations and longer surgery durations than dogs that did not have cholecystectomy. No significant differences existed for temperature nadir (34.8 <italic>versus</italic> 35.3 °C; non‐cholecystectomy <italic>versus</italic> cholecystectomy), final temperature (35.6 <italic>versus</italic> 35.9 °C), time to extubation (30 <italic>versus</italic> 49 minutes), duration of hypotension (27 <italic>versus</italic> 21 minutes), or MAP nadir (56 <italic>versus</italic> 55 mmHg). Hypotension occurred in 66% and 74% and inotropes were used in 64% and 53%, for non‐cholecystectomy and cholecystectomy patients, respectively.</p> </sec> <sec id="vaa12100-sec-0006" sec-type="section"> <title>Conclusions and clinical relevance</title> <p>Dogs that underwent cholecystectomies did not suffer a greater number of anesthesia complications than did dogs undergoing hepatic surgery without cholecystectomies.</p> </sec> </abstract>
