硬膜外阻滞麻醉用于无痛分娩的临床观察

目的探讨硬膜外麻醉用于分娩镇痛的效果及对产程、母婴状况的影响。方法将采取低浓度连续硬膜外自控泵入阻滞麻醉用于分娩镇痛412例作为观察组，将来采用任何分娩镇痛药物而进入产程的产妇412例作为对照组。分别观察产程时问、分娩方式、产后出血量及对胎儿和新生儿状况的影响。结果2纽分娩活跃期比较，有极显著性差异（P〈0．01）；2组分娩方式比较有显著性差异（P〈0．05）；2组胎儿窘迫、新生儿窒息及产后出血发生率比较，无显著性差异（P〉0．05）。结论低浓度连续硬膜外自控泵入阻滞麻醉法用于分娩镇痛，疼痛阻滞效果可靠，缩短了产程活跃期和第二产程时间，加速了产程进展，减少了产妇的体力消耗，从而增加了阴道分娩率，降低了剖宫产和阴道难产率，对产妇有利而对婴儿无不良影响。
