Evaluation of cats treated with robenacoxib after gastrointestinal surgery.

Objectives: The aim of the study was to determine if cats administered robenacoxib immediately after gastrointestinal surgery have a similar complication rate to cats that were not administered robenacoxib.

Methods: Medical records were reviewed for 154 cats that underwent gastrointestinal surgery between December 2015 and September 2021 in this retrospective study. Data collected included patient signalment, presenting complaint, surgical procedure(s) performed, robenacoxib administration and major postoperative complications. Cats were excluded if they did not have a 2-week postoperative follow-up examination. Two groups were analyzed: group R (postoperative robenacoxib administration) consisted of 43 cats; and group C (no postoperative robenacoxib administration) consisted of 111 cats.

Results: Complications occurred in 10/43 (23.2%) cats in group R and 34/111 (30.6%) cats in group C. Major complications occurred in 1/43 (2.3%) in group R and 14/111 (12.6%) in group C. Minor complications occurred in 9/43 (20.9%) cats in group R and 20/111 (18.0%) cats in group C. One of 43 cats (2.3%) in group R and 10/111 (9.0%) cats in group C were euthanized or died within 0-16 days after gastrointestinal surgery.

Conclusions and relevance: Cats that were administered robenacoxib postoperatively did not have an increase in major postoperative complications after gastrointestinal surgery compared with cats that were administered an alternative analgesic medication. The use of robenacoxib in cats after gastrointestinal surgery may be a safe analgesic option for postoperative pain control.
