活跃期进行连续硬膜外阻滞分娩镇痛的临床观察

目的：探讨连续硬膜外阻滞用于活跃期分娩镇痛，对产力，产程及母儿状况的影响。方法 将230例正常分娩的初产妇随机分为镇痛组和对照组。镇痛组于活跃期施行连续硬膜外阻滞分娩镇痛，其他产科处理措施同于对照组。观察两组的产痛程度，产程时间，胎儿宫内窘迫率，新生儿Apgar评分，新生儿窒息率，产后出血率，阴道助产率，催产素使用率等情况。结果：镇痛组与对照组相比，阵育强度有显著差异（P＜0．01），除第2产程时间稍长于对照组（P＜0．05），两组的胎儿宫内窘迫率，新生儿Apgar评分，新生儿窒息率，产后出血率，阴道助产率，催产素使用率均无显著性差异（P＞0．05）。结论 连续硬膜外阻滞用于活跃期分娩镇痛，镇痛效果确定，不影响产程进展，同时不增加产后出血，阴道助产及催产素的使用，对新生儿无不良影响。

Clinical observeation of labor pain relief using continouse epidural analgesia in active phase

To investigate the labor pain relief effects of continouse epidural analgesia in active phase and its influense on both mothers and infants. 230 Primary prognent women were divided into study group and control group randomly.The treatment of all prognent women was not different excepted that the epidural analgesia were used in active phase of study group .The degree of pain ,the time of labor phase,the rate of destress,Apgar scores,the rate of postpartum hemorrhage ,the rate of viginal dystocia, neonatal asphyxia and the rate of using uterin were observed on two groups. The degree of pain relief of study group was more intensity than that of control group markedly ( P <0.01) amd compare with control group excepted that the second couse of study group was longer than control group( P >0.05) however the other items were not different( P <0.05). Conclusion] This method has the effects of pain relief observably ,not influence on labor phase ,mothers and infants .Then it also not increase postpartum hemorrhage,viginal delivered and the using of uterin .
