为了观察不同的等比重局麻药液在脊麻剖宫产术中的麻醉效果 ,我们选择 60例ASAI级、拟行择期剖宫产术的产妇 ,随机分为三组 ,分别应用等比重 2 %利多卡因 1 5ml,等比重 0 5%布比卡因2ml,及两者 1 :1混合液 2ml,作为脊麻用药 ,采用双盲法观察麻醉时效及有关并发症。结果表明 ,三组麻醉诱导时间分别为利多卡因组 5 2 0± 1 .55分钟 ,布比卡因组 1 2 2 0± 3 51分钟 ,混和组 6 90± 2 1 3分钟 ,三者麻醉维持时间分别为 3 9 50± 1 0 50分钟 ,1 0 2 50± 1 7 0 5分钟和 64 50± 1 0 99分钟。我们认为等比重 2 %利多卡因与 0 5%布比卡因 1 :1混合液 ,可作为单剂脊麻剖宫产术的用药
In order to observe the different anesthetic effects of different proportions of local anesthetic solution in spinal cesarean section, we selected 60 ASAI-class, scheduled elective cesarean section of women were randomly divided into three groups, respectively, with an equal proportion of 2 % Lidocaine 15ml, 0 5% 0% bupivacaine 2ml, and a mixture of the two 1: 1 2ml, as spinal anesthesia, anesthesia and double-blind observation of complications and complications. The results showed that the induction time of anesthesia in the three groups was respectively 52 ± 0.55 minutes for lidocaine group, 1220 ± 311 minutes for bupivacaine group and 6 90 ± 21 3 minutes for mixed group. The three groups were anesthetized Maintenance time was 3 9 50 ± 10 0 minutes, 10 2 50 ± 1 7 0 5 minutes and 64 50 ± 1 0 99 minutes, respectively. We believe that the same proportion of 2% lidocaine and 0.5% bupivacaine 1: 1 mixture can be used as a single dose spinal cesarean section medication
