持续硬膜外阻滞应用于分娩镇痛40例报告

40 Cases Report of the Persistent Epidural Anesthesia Applied to Relieve Labor Pain

目的 探讨持续硬膜外阻滞的镇痛效果及对母婴的影响。方法 选择 40例无产科及麻醉禁忌证的初产妇 (观察组 ) ,在宫口开大 3cm以上时 ,给予持续硬膜外麻醉 ,并与同期条件相似 ,未给予任何镇痛方法的 40例产妇进行对照 (对照组 )。分别观察两组产痛程度、产程进展速度、分娩方式、催产素使用情况、出血率、宫内窘迫、新生儿窒息率情况。结果 观察组镇痛效果明显。观察组催产素使用率、第二产程时间、经阴道助产分娩率有显著差异 (P <0 0 5 ) ,剖宫产率、出血率及宫内窘迫、新生儿窒息率两组比较 ,差异无显著性 (P >0 0 5 )。结论 该法应用于分娩镇痛 ,方法简单 ,镇痛效果明显 ,但对分娩方式有一定影响 ,应进一步完善。

Objective To investigate the pain-relieving effectiveness of persistent epidural anesthesia and its influence on mothers and infants.Methods 40 pregnant women without any obstetric complications and anesthetic contraindications were selected as the observation group,and persistent epidural anesthesia were applied when the cervicis opened to be larger than 3cm.40 cases with similar obstetric conditions were regarded as the control group without using any anesthesia.We compared the degree of labor pain,duration,delivery mode,the incidence of postpartum hemorrhage,intrauterine distress,neonatal asphyxia between the two groups.Results There were significantly difference in the rate of oxytocin utilization,vaginal delivery and the time of stageⅡ labor.There were no obvious difference in the active phase of labor course,the incidence of cesarean birth,intrauterine distress,neonatal asphyxia and postpartum hemorrhage between the two groups.Conclusions The results indicate that epidural anesthesia could affect the length of stageⅡ labor time and have merits of simple,obvious analgetic effect,but inflecencing delivery mode,therefore it to be improve.
