Abstract

This prospective, blinded, controlled clinical study compared the effects of pre-emptive oral administration of carprofen or tramadol on pain scores and analgesic requirement in dogs undergoing cutaneous tumor removal. Thirty-six client-owned dogs presenting for cutaneous tumor removal were randomly assigned to receive carprofen, tramadol, or no treatment prior to surgery. Pain was assessed using a visual analog scale (VAS), the Modified Glasgow Composite Measure Pain Score (MGCMPS), and algometry at enrollment, prior to premedication, at extubation, then hourly for the first 4 h, and every 4 h for 24 h. Dogs scoring ≥ 7 (MGCMPS), or having a VAS measurement ≥ 40 mm were given rescue analgesia. There were no significant differences in pain VAS, MGCMPS, or algometry. There were no differences in rescue analgesia requirement, or time to rescue analgesia among groups. Carprofen, tramadol, or no pre-emptive analgesia, combined with pre-operative hydromorphone and rescue analgesia, resulted in satisfactory analgesia in the 24-hour postoperative period.
