吸入笑气分娩镇痛170例临床分析

目的探讨吸入笑气分娩镇痛的效果及对产程、母婴状况的影响。方法采用吸入笑气分娩镇痛的产妇170例作为观察组，将未采用任何分娩镇痛药物而进入产程的170例作为对照组，分别观察产程时间、分娩方式、产后出血、胎儿窘迫及新生儿窒息情况。结果观察组的阵痛强度评分明显低于对照组（P〈0．01），两组产程活跃期比较，有极显著性差异（P〈0．01）；两组分娩方式比较有显著性差异（P〈0．05）；两组胎儿窘迫、新生儿窒息及产后出血发生率比较，无显著性差异（P〉0．05）。结论吸入笑气分娩镇痛产程时间短，降低了剖宫产及阴道难产率，对母婴均无不良影响。

The Effect of Inhaling Laughing Gas for Labor Pain Relief

Objective To investigate the efficiency of inhaling laughing gas for labor pain relief and its influences on the labor and both mothers and infants.Methods 170 pregnant women were inhaling laughing gas for labor pain relief(study group)and the other 170 pregnant women with no any labor analgesia were regarded as control group.We observed the labor course,the mode of delivery and incidence of postpartum hemorrhage,fetal distress and neonatal in the two groups respectively.Results The score of labor pains in the observational group was significantly lower than that in the control one(P<0.01).The difference was effectively significant in the active phase(P<0.01) between the study group and the control group,while there was no significant difference in the incidence of postpartum hemorrhage,fetal distress and neonatal asphyxia(P>0.05).Conclusion Analgesic labor with inhaling laughing gas produces a short delivery process and there were no influences on mothers and infants.It also decreased the rate of cesarean and vaginal dystocia.
