硬膜外麻醉与笑气无痛分娩临床应用

CLINICAL APPLICATION OF EPIDURAL ANESTHESIA AND PAINLESS LABOR WITH NITROUS OXIDE

目的探讨硬膜外麻醉和笑气无痛分娩的特点及临床应用价值。方法选择2008年2月至2009年12月在我院分娩的孕妇780例为观察对象,其中400例采用笑气无痛分娩(笑气组),380例采用硬膜外阻滞麻醉无痛分娩(硬膜外组),观察比较两组镇痛效果、活跃期所需时间及第2产程时间、分娩方式、胎儿窘迫率及新生儿情况。结果硬膜外组阵痛效果优于笑气组,第2产程长于笑气组,器械助产率高于笑气组,差异有显著性(P<0.05),而两组活跃期所需时间,自然产率、剖宫产率及胎儿窘迫新生儿情况比较差异无显著性(P>0.05)。结论硬膜外麻醉和笑气镇痛分娩,镇痛效果肯定,安全可靠,副作用小,各有所长,临床上可选择应用。

Objective To explore the characteristics and clinical value of epidural anesthesia and painless labor with nitrous oxide.Methods 780 cases of pregnant women from February,2007 to December,2007 in our hospital were randomly chosen as the subjects. 400 cases received painless labor with nitrous oxide,and the rest underwent painless labor with epidural anesthesia. The differences between the two groups in labour pains,time for active period and second phase,delivery model,fetal distress rate and situation of neonatal were observed.Results The curative effects of epidural anesthesia were better,the second course of delivery was longer and the rate of using obstetric apparatus was higher in the epidural anesthesia group than those in the nitrous oxide group（P0.05）.Conclusion Epidural anesthesia and painless labor with laughing gas are effective,safe methods of delivey with few side effects and are worthwhile to be widely applied.
