小剂量轻比重布比卡因单侧腰麻-硬膜外联合麻醉在高龄换髋手术中的应用

The application of small dose and light gravity bupivacaine for unilateral lumbar epidural anesthesia in elderly hip exchange surgery

目的:探讨在高龄患者换髋手术中应用小剂量轻比重布比卡因单侧腰麻-硬膜外联合麻醉的效果。方法:收治髋关节置换术患者78例,分为探究组和参照组。参照组患者接受连续硬膜外麻醉,探究组患者接受小剂量轻比重布比卡因单侧腰麻-硬膜外联合麻醉。结果:麻醉后,参照组患者心率以及血压下降幅度明显超过探究组(P<0.05);探究组麻醉维持时间短于参照组,感觉阻滞起效时间长于参照组,Bromage评分低于参照组(P<0.05)。结论:在高龄患者换髋手术中应用小剂量轻比重布比卡因单侧腰麻-硬膜外联合麻醉安全性更高,同时也能够取得较为理想的麻醉效果。

Objective：To investigate the effect of small dose light specific gravity bupivacaine combined spinal epidural anesthesia in elderly patients undergoing hip replacement.Methods：78 patients undergoing hip replacement were selected.They were divided into the study group and the reference group.The patients in the reference group received continuous epidural anesthesia,and the patients in the study group received low-dose light weight bupivacaine combined with unilateral spinal epidural anesthesia.Results：After anesthesia,the decrease of heart rate and blood pressure in the reference group was significantly higher than that in the study group（P〈0.05）;the duration of anesthesia of the study group was shorter than that of the reference group,and the onset time of sensory block was longer than that in the reference group,and the Bromage score was lower than that of the reference group（P〈0.05）.Conclusion：In elderly patients undergoing hip replacement surgery,small dose of light weight bupivacaine combined with unilateral spinal epidural anesthesia is safer and ideal anesthetic effect can be achieved.
