Postoperative analgesic effects of intravenous lornoxicam and morphine with pre-emtive ropivacaine skin infiltration and preperitoneal instillation after transabdominal hysterectomy.

Unlabelled: To investigate the effectiveness of intravenous lornoxicam and morphine with the preemptive effects of ropivacaine local skin infiltration and peritoneal instillation in reducing postoperative pain after transabdominal hysterectomy, a randomized, double blinded, placebo-controlled study was done in 88 patients undergoing transabdominal hysterectomy under general anesthesia. The patients were allocated into 4 groups to receive: (group A) only intravenous morphine 10 mg; (group B) intravenous morphine 10 mg and lornoxicam 16 mg; (group C) intravenous morphine 10 mg, lornoxicam 16 mg with 0.5 per cent ropivacaine local skin infiltration before skin incision and 1 per cent ropivacaine instillation before peritoneal incision; (group D) intravenous morphine 10 mg, lornoxicam 16 mg with 1 per cent ropivacaine instillation after peritoneal closure and 0.
