Abstract:
[Objective]Postoperative analgesia with the use of parenteral opoids or epidural analgesia can be associated with troublesome side effects.Good perioperative analgesia facilitates rehabilitation,improves patient satisfaction,and may reduce the hospital stay.We investigated the analgesic effect of locally injected drugs around a total knee prosthesis.[Method]Thirty-eight patients undergoing total knee arthroplasty were randomized either to reveive a periarticuiar intraoperative injection containing bupicaine,morphine,epinephrine,hydrocordisone or to reveive no injection.We compared the PCA consumption at the some time point after tatal knee arthroplasty.Visual analog scores for pain,preoperation and postoperation,6 weeks after operation were collected.[Result]The patients who had received the injection used significantly less patient-controlled analgesia over the first 24 hours after the surgery.They had lower visual analog scores for pain 24 hours and 48 hours after operation.No cardiac or central nervous system toxicity was observed.[Conclusion]The perioperative analgesia protocol improved patient satisfaction,pain control and minimizes side effects after total kneearthroplasty.
