Analgesic effects of gabapentin and buprenorphine in cats undergoing ovariohysterectomy using two pain-scoring systems: a randomized clinical trial:

ObjectivesThe aim of the study was to evaluate the analgesic efficacy of gabapentin–buprenorphine in comparison with meloxicam–buprenorphine or buprenorphine alone, and the correlation between two pain-scoring systems in cats.MethodsFifty-two adult cats were included in a randomized, controlled, blinded study. Anesthetic protocol included acepromazine–buprenorphine–propofol–isoflurane. The gabapentin–buprenorphine group (GBG, n = 19) received gabapentin capsules (50 mg PO) and buprenorphine (0.02 mg/kg IM). The meloxicam–buprenorphine group (MBG, n = 15) received meloxicam (0.2 mg/kg SC), buprenorphine and placebo capsules (PO). The buprenorphine group (BG, n = 18) received buprenorphine and placebo capsules (PO). Gabapentin (GBG) and placebo (MBG and BG) capsules were administered 12 h and 1 h before surgery. Postoperative pain was evaluated up to 8 h after ovariohysterectomy using a multidimensional composite pain scale (MCPS) and the Glasgow pain scale (rCMPS-F).
