Duration Of Labor/cesarean Delivery With Epidural Analge

我们与夏威夷特里普勒陆军医学中心的研究人员合作，提出了一项建议，以检查硬膜外镇痛对未产妇产程和剖宫产率的影响。我们选择了两个时期：1992年10月至1993年9月，硬膜外镇痛期；1995年10月至1996年9月，65%的新生儿使用硬膜外镇痛术。从医疗记录(每个时期约600名患者)中提取关于母亲的人口统计特征、分娩和分娩过程以及分娩镇痛的详细信息。我们已经完成了数据收集。在数据分析中，我们比较了这两个时期的产程和剖宫产率。此外，我们还检查了硬膜外镇痛是否会增加枕后位和母体体温过高的发生率。目前正在进行数据分析。

In collaboration with investigators at the Tripler Army Medical Center, Hawaii, we developed a proposal to examine the effects of epidural analgesia on the course of labor and cesarean delivery rate in nullipara. We selected two periods: from October 1992 to September 1993 when epidural analgesia was not available, and from October 1995 to Spetember 1996 when epidural analgesia was used in 65% of births. Detailed information on maternal demographic characteristics, course of labor and delivery, and labor analgesia were extracted from the medical records (about 600 patients in each period). We have completed data collection. In the data analysis, we compared the duration of labor and rates of cesarean delivery between these two periods. In addition, we examined whether epidural analgesia increases the incidence of occiput posterior position and maternal hyperthermia. Data analyses are being conducted.
