Studies were done on 12 healthy female dogs brought for ovariohysterectomy as an elective surgery. Surgery was done through a right flank incision under atropine-xylazine-ketamine anaesthesia. In six animals pentazocine lactate (2 mg/kg) was administered intramuscularly preoperatively while another six animals received this drug at the same dose rate immediately after completion of surgery. A numerical rating scale using several behavioural parameters was used to assess pain. Mean total pain scores indicated that pentazocine (2 mg/kg) effectively controls the moderate postoperative pain caused by ovariohysterectomy. The blockade of pain appears to be slightly better in those animals where pentazocine was administered preoperatively. It appears that determination of plasma cortisol concentration can be a useful tool to assess the intensity of pain. The results also indicated that if moderate pain caused by a surgical procedure is effectively controlled in first 24 postoperative hours, subsequent administration of analgesic drug may not be required.Publisher: College of Veterinary Sciences, Haryana Agricultural University
