目的探讨笑气吸入用于分娩镇痛的临床疗效。方法选取2008年1月-2012年12月住院待产足月单胎头位初产妇200例,所有产妇均拟阴道分娩,依照产妇是否要求分娩镇痛分为观察组和对照组各100例。观察组予笑气吸入,对照组不予笑气吸入。比较2组分娩状况。结果观察组分娩镇痛总有效率88.0%。观察组自然分娩率明显高于对照组,差异有统计学意义(P<0.01);胎吸率、产钳率2组比较差异无统计学意义(P>0.05);观察组剖宫产率明显低于对照组率,差异有统计学意义(P<0.01)。新生儿评分、产后出血和胎儿窘迫2组比较差异无统计学意义(P>0.05)。结论笑气吸入用于分娩镇痛效果肯定,值得临床推广应用。
Objective To investigate the clinical efficacy of nitrous oxide inhalation for labor analgesia. Methods A total of 200 primiparae of singleton fetuses of full-term hospitalized from January 2008 to December 2012 were enrolled in this study. All the mothers were given vaginal delivery and were divided into observation group and control group according to whether the woman asked for labor analgesia. The observation group was given inhalation of nitrous oxide, and the control group did not inhale. Compare the 2 component delivery status. Results Observation group labor analgesia total effective rate 88.0%. The rate of spontaneous delivery in the observation group was significantly higher than that in the control group (P <0.01). There was no significant difference between the two groups in the rate of fetal suction and the rate of the forceps (P> 0.05). The cesarean section rate in the observation group was significantly lower In the control group, the difference was statistically significant (P <0.01). Neonatal score, postpartum hemorrhage and fetal distress in the two groups showed no significant difference (P> 0.05). Conclusions Inhalation of nitrous oxide for labor analgesic effect is worthy of clinical promotion and application.
