ABSTRACT

Objective To investigate the effect of pretreatment with parecoxib for postoperative analgesia in patients undergoing laparoscopic hernia repair. Methods Sixty patients undergoing laparoscopic hernia repair were assigned in two groups by random digits table with 30 cases each. The patients in pretreating group received parecoxib 40 mg intravenously before anesthesia, and in control group with the same capacity of normal saline. All patients were anesthetized with combined spinal epidural blockage and tranquilized with pethidine, droperidol and diazepam. Postoperative pain of the abdomen incision was assessed by visual analogue scale (VAS) and the pain of shoulder or back was judged by a 4 grade scale. Side-effects, supplement analgesic, passage of gas by anus 24 h after surgery were observed as well. Results The abdomen incision VAS at 4,8,12,24 h after surgery in pretreating group were lower than those in control group (P ＜ 0.05). And the incidence of pain of shoulder or back was lower in pretreating group (13.3% ,4/30) than that in control group (33.3% ,10/30)(P ＜0.05). While the cases needing supplement analgesic also decreased in pretreating group (13.3% ,4/30) compared with control group (40.0%, 12/30)(P ＜ 0.05). And the side effects and passage of gas by anus 24 h after surgery had no significant difference in two groups. Conclusion Pretreatment with parecoxib in patients undergoing laparoscopic hernia repair may relieve the postoperative incision pain and the pain of shoulder or back while reducing the analgesic supplement without side effects.
