摘要: 目的:探讨罗哌卡因复合布托啡诺行硬膜外分娩镇痛时布托啡诺的半数有效剂量(ED50)和罗哌卡因的最佳有效浓度。方法:121例初产妇接受L2-3硬膜外分娩镇痛,前31例患者中第一个患者接受 0.15%罗哌卡因+20 μg/mL 布托啡诺复合液,随后的产妇运用改良序贯法确定布托啡诺的ED50。另90例患者按硬膜外用药不同随机分为 0.08%罗哌卡因+16 μg/mL 布托啡诺(B1组)、0.10%罗哌卡因+16 μg/mL 布托啡诺(B2组)及 0.12%罗哌卡因+16 μg/mL 布托啡诺(B3组)。监测分娩镇痛过程中阻滞平面和运动阻滞(Bromage评分)、镇静镇痛评分及宫缩胎心;记录麻醉起效时间、产程时间、分娩方式、缩宫素使用增加例数以及新生儿Apgar评分,记录恶心、呕吐 、瘙痒、胎心减速等副作用发生率。结果:布托啡诺的ED50值及ED95值分别为14.79(95%CI 13.91~15.61)和 16.84(95%CI 15.86~20.97) μg/mL。B1组镇痛起效时间明显长于B2、B3组(P<0.05),给药后30、60和 90 min 时的VAS评分明显高于B2、B3组,停药时VAS评分明显高于B3组(P<0.05);B1组在镇痛后第4~6次宫缩时的VAS评分明显高于B2、B3组(P<0.05)。B3组运动神经阻滞发生的例数明显高于B1、B2组(P<0.05)。结论:0.10%罗哌卡因复合16 μg/mL布托啡诺行分娩镇痛时镇痛效果好、无运动阻滞、安全性高,值得临床推广。

Abstract: AIM: To investigate the ED50 of butorphanol combined with 0.15% ropivacaine and the most effective concentration of ropivacaine combined with butorphanol in labor epidural analgesia.METHODS: 121 nulliparous women undergoing labor selected for delivery with epidural analgesia. The first of the top 31 woman received 0.15% ropivacaine plus 20 μg/mL butorphanol 10 mL, the next woman's dose of the butorphanol was determined by a modification of sequential method. The other 90 women received 0.08% ropivacaine and butorphanol 16 μg/mL (Group B1), 0.10% ropivacaine and butorphanol 16 μg/mL (group B2), 0.12% ropivacaine and butorphanol 16 μg/mL(group B3) respectively.In the course of labor, block levels of epidural analgesia, the Bromage scores, Ramsay scores, fetal heart rate-uterine contraction were monitored. In addition, onset time of anesthesia, labor time, the cases of oxytocin using, Apgar scores of neonates and side-effect were recorded.RESULTS: There were no significant differences in age, height, weight and gestational weeks in every woman.The ED50 of butorphanol was 14.79 μg/mL (95%CI 13.91~15.61 μg/mL). The ED95 of butorphanol was 16.84 μg/mL (95%CI 15.86~20.97 μg/mL). The onset of anesthesia in group B1 was significantly longer than other two groups (P<0.05). The VAS scores at 30 min, 60 min, 90 min after injection in group B1 was significantly higher than those in other two groups(P<0.05), and the VAS scores when drug withdraw in group B1 was significantly higher than those in group B3(P<0.05). Group B3 showed higher motor block than other two groups (P<0.05).CONCLUSION: 0.10% ropivacaine combined with butorphanol 16 μg/mL is the most effective for epidural analgesia in labor. It is worth clinical application for its kind analgesic effect, slight motor block and high safety.
