摘要
目的探讨小剂量芬太尼试验能否预测老年患者芬太尼静脉镇痛的效果和安全性。方法30例老年患者,麻醉诱导前静脉注射芬太尼50μg,2min后根据患者反应情况分为有症状A组和无症状B组,手术结束后行芬太尼静脉镇痛,采用双盲法观察术后6h、24hVAS评分以及术后24h内副作用发生率和副作用严重程度。结果30例患者中18例出现症状为A组,12例无任何症状为B组,A组患者6h、24h镇痛满意率(VAS≤3)、术后24h内副作用发生率和副作用严重程度明显明显高于B组(P<0.05)。结论小剂量芬太尼试验出现症状的老年患者术后芬太尼静脉镇痛效果好而副作用大于无症状患者,表明麻醉诱导前小剂量芬太尼试验可以预测老年患者术后静脉镇痛效果和安全性。
effectiveness and Objective To investigate whether a small dose of fentanyl can safety of fentanyl continuous intravenous postoperative analgesia predict the in elderly patients. Methods 30 cases of aged patients were administrated 50μg of fentanyl Ⅳ before the induction of anesthesia. According to their response, all cases were divided into group A and group B, then all cases were treated with fentanyl continuous intravenous postoperative analgesia. Visual analog scale （VAS） at 6h,24h after operation,incidence and severity of side effects were recorded. Results 18 patients were categorized as group A and 12 patients were categorized as group B.Ratio of VAS≤3 at 6h,24h after operation,incidence and severity of side effects were significant differences between group A and B （P〈0.05）. Conclusion A small dose of fentanyl given before the induction can predict the effectiveness and safety of fentanyl continuous intravenous postoperative analgesia in elderly patients.
