硬膜外阻滞麻醉用于无痛分娩的临床观察

目的探讨分娩镇痛的效果及对产程、母婴的影响。方法采用PECA泵硬膜外腔给药用于分娩镇痛，观察产程时间、分娩方式、产后出血、胎儿宫内窘迫及新生儿窒息情况。结果观察组和对照组产程比较、两组分娩方式比较有显著性差异（P〈0．01）；两组胎儿宫内窘迫，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PECA泵用于持续硬膜外腔给药镇痛，疼痛阻滞完善，加速了产程的进展，降低了剖宫产率阴道难产率，对母婴均无不良影响。

Clinical Observation of Epidural Analgesia for Labor Pain

Objective To study the pain relief effectiveness and its influence on the labor course, and both the mothers and the newboms. Methods The pump of PECA （patient controlled epidural analgesia） was used during labor in the study group. The labor course, the methods of delivery, the incidence of post parturn hemorrhage, fetal distress and neonatal asphyxia were observed respectively in the groups. Results There were significant differences between both groups in the stage of labor and delivery modes. There were no significant differences in the incidences of post partum hemorrhage, fetal distress and neonatal asphyxia（P〉0.05）.Condusioa The pump of PECA during labor is safe and effective, which accelerates course of labor and reduce the rates of cesarean and dystocia.
