Plain-English summary
A group of 167 dogs undergoing eye removal surgery (enucleation) was studied to see if using a specific local anesthetic (bupivacaine) caused more complications. The results showed that dogs who received the bupivacaine had a lower risk of recovery complications compared to those who did not receive it. Specifically, 21.6% of dogs with the anesthetic had complications, while 38.6% of those without it did. Overall, using bupivacaine did not lead to more serious issues during or after the surgery, making it a safe option for pain management in these cases.

Abstract
OBJECTIVE: To investigate complications associated with, and without, bupivacaine retrobulbar local anesthesia in dogs undergoing unilateral enucleation surgery. STUDY DESIGN: Retrospective, observational study. ANIMALS: A total of 167 dogs underwent unilateral enucleation surgery via a transpalpebral approach. METHODS: Records from 167 dogs that underwent unilateral enucleation surgery that did (RB) or did not (NB) include retrobulbar bupivacaine anesthesia were reviewed, including anesthetic record, daily physical examination records, surgery report, patient discharge report and patient notes within 14 days of the surgery. Specific complications and severity were compared between RB and NB using the Wilcoxon rank-sum test. A 'complication burden' (0-5) comprising five prespecified complications was assigned and tested using rank-sum procedures. Statistical significance was set to 0.05. RESULTS: Group RB included 97 dogs and group NB 70 dogs. Dogs in NB had a 17.0 percentage points (points) greater risk for a postoperative recovery complication (38.6% versus 21.6%; 95% confidence interval: 3.0-30.6 points; p = 0.017). There was inconclusive evidence that dogs in group RB had a lower risk of requiring perioperative anticholinergic administration (12.4% versus 22.9%; 10.5 points; p = 0.073). Other complications were similar between groups RB and NB with risks that differed by <10 points. The risk of hemorrhage was similar between groups RB (22.7%) and NB (20.0%) with no significant difference in the level of severity (p = 0.664). CONCLUSIONS AND CLINICAL RELEVANCE: In this retrospective study, the use of retrobulbar bupivacaine for enucleation surgery in dogs was not associated with an increased risk of major or minor complications.
