ABSTRACT

Objective To compare the effects of butorphanol,midazolam and innovar on relieving appendix traction response during appendectomy. Methods Sixty-eight patients who underwent appendectomy were randomly divided into butorphanol group(n=21),midazolam group(n=23) and innovar group(n=24).Butorphanol,midazolam and innovar were intravenously administered to patients during skin incision.The appendix traction response,sedation score,heart rate(HR),mean arterial pressure(MAP) and pulse oxygen saturation(SpO2) were recorded and compared among groups.Results Compared with those before operation,there was no significant changes in HR,MAP and SpO2 during operation.The effective rates of butorphanol,midazolam and innovar in relieving appendix traction response were 95.2%,65.2% and 50.0%,respectively.Butorphanol surpassed midazolam and innovar in sedation and relieving appendix traction response(P
