Abstract

No significant differences in total surgical time were found between ovariohysterectomy (OVH) and ovariectomy (OVE) procedures in 40 healthy female dogs.

Body weight was positively correlated with total procedure duration and time for surgical wound closure.
Skin and fascia incision lengths were significantly greater in OVH compared to OVE.
No significant differences in pain scores or wound characteristics were detected between the two surgical groups.
Body condition score showed no effect on any measured variables.

OBJECTIVE: To determine whether ovariohysterectomy (OVH) required more time to complete and was associated with more short-term postoperative complications than ovariectomy (OVE) in dogs.

DESIGN: Randomized prospective clinical trial.

ANIMALS: 40 healthy, sexually intact female dogs.

PROCEDURES: OVH (in 20 dogs) or OVE (20 dogs) was performed by use of standardized anesthetic and surgical protocols. Physical characteristics of the dogs, surgical variables, pain scores derived from behavior-based composite pain scales, and surgical wound characteristics were analyzed.

RESULTS: Body weight, age, body condition score, and distance between the sternal manubrium and the pubic rim were comparable among dogs that underwent either surgical procedure. Body weight was positively correlated with the total duration of the procedure and with time required for closure of the surgical wound. No effect of body condition score was determined for any variable. Skin and fascia incision lengths relative to the distance from the sternal manubrium to pubic rim were significantly greater in dogs that underwent OVH, compared with those of dogs that underwent OVE, but total surgical time was not different for the 2 procedures. No other significant differences were detected between the 2 groups.

CONCLUSIONS AND CLINICAL RELEVANCE: Significant differences in total surgical time, pain scores, and wound scores were not observed between dogs that underwent OVH and dogs that underwent OVE via standardized protocols.
