笑气(N_2O)吸入性分娩镇痛120例临床研究

Clinical observation of N_2O inhaled labor analgesia in 120 cases

目的:观察笑气吸入性分娩镇痛在临床的应用效果。方法:观察两组患者(各120例)的产程进展、产时产后出血量及剖宫产率。结果:观察组产程平均为(562±150)min,对照组为(730±160)min,观察组明显短于对照组(P<0.05);观察组产时出血量平均为(165±10)ml,明显少于对照组(175±15)ml(P<0.05);产后2 h累计出血量观察组平均为(236±25)ml,对照组为(242±27)ml,两组比较,差异无统计学意义(P>0.05);剖宫产率观察组(87.5%)明显低于对照组(77.5%)(P<0.05)。结论:笑气吸入性分娩镇痛无创、易操作,且可以明显缩短产程,降低剖宫产率,有较高的临床应用价值。

Objective：To investigate the clinical efficacy of N2O inhaled labor analgesia.Methods：The labor progress,intrapartum,postpartum hemorrhage,neonatal score and the rate of cesarean of the patients of these two groups（120 cases each group） were observed.Results：The labor of the observation group（562±150） min was shorter than that of the control group（730±160） min（P0.05）;there was a significant difference in the intrapartum [（165±10） ml vs（175±15） ml]（P0.05） and there was no significant difference in the 2 h postpartum hemorrhage [（236±25） ml vs（242±27） ml]（P0.05）,the rate of cesarean of the observation group（87.5%） was obviously lower than that of the control group（77.5%）（P0.05）.Conclusion：N2O inhaled labor analgesia is so noninvasive and easily operated that can be used widely,with shortening the duration of labor and lowering the cesarean rate significantly.
