Comparison of two haemostasis techniques on procedural duration, postoperative pain and gastrointestinal function in pet rabbits undergoing ovariohysterectomy.

Ovariohysterectomy is a common surgical procedure in pet rabbits and one of its potential complications is postoperative gastrointestinal stasis, possibly exacerbated by prolonged surgery time. The objective of this prospective clinical study was to compare two techniques for surgical haemostasis with respect to procedural duration, postoperative pain, and return of gastrointestinal function, in 22 female rabbits undergoing ovariohysterectomy. Rabbits were assigned to one of two groups: conventional vessel ligation (CVL) and haemostasis with a vessel sealing device (VSD). The outcome variables for comparison between the two groups, recorded at 60-, 120-, 180-, and 360-minutes post anaesthesia, were duration of anaesthesia and surgery, postoperative Rabbit Grimace Scale scores, and measured food intake and faecal output. The vessel sealing device caused no appreciable blood loss. The duration of both surgery and anaesthesia was shorter in group VSD (20 ± 4 and 31 ± 6 minutes, respectively) than in group CVL (43 ± 9 and 54 ± 9 minutes, respectively) (p<0.001). There were no differences between groups in time elapsed from the end of anaesthesia to both first food intake and first defecation. In both groups, the score of the Rabbit Grimace Scale decreased over time with statistically significant differences between 60 minutes and all the subsequent time points (p<0.001). Vessel sealing devices may be recommended over conventional haemostasis for rabbit ovariohysterectomy to decrease the duration of surgery and anaesthesia, with potential beneficial effects on sustainability and practice workflow.
