目的：研究讨论腰硬联合阻滞麻醉对消除或者减轻产痛的方面的作用及其对分娩方式、胎儿、产程的影响。方法：选取无产科、麻醉禁忌证的65例初产妇作为观察组，行腰硬联合阻滞麻醉镇痛。同时选取同时期65例未行任何镇痛办法且条件类似的初产妇作为对照组，进行比较。结果：两组镇痛有效率、剖宫产率和经阴道助产分娩率差异显著（P＜0．01）。而胎儿窘迫、新生儿窒息、第一产程及产后出血发生率差异不明显（P＞0．05）。结论：腰硬联合阻滞麻醉可起到分娩镇痛和降低剖宫产率的作用，虽然减慢了宫口扩张速度、延长了活跃期，但对第一产程无影响，其安全、有效，值得应用和推广。“,”Objective:To study the discussion waist hard joint block anesthesia to eliminate or relieve labor pain of the role of,its influence on the way of delivery,the fetus,labor.
