产前呼吸控制训练对分娩的影响

目的探讨在产前进行呼吸控制训练对分娩的影响。方法对孕35～36周初产妇190例随机分为实验组（100例）和对照组（90例），对实验组孕妇进行以吐气为中心的呼吸控制练习；比较两组分娩时呼吸运用依从率、顺产率、产程中疼痛分值、产程时间、产后2h出血量、早产及胎膜早破等分娩并发症的差异。结果依从率、顺产率、羊水Ⅱ～Ⅲ度污染率及产程时间、产程中疼痛分值、产后2h内出血量等比较，两组间均有显著性差异（P〈0．05）；两组早产、胎膜早破及新生儿窒息率比较无显著性差异（P〉0．05）。结论分娩前进行呼吸控制训练能提高产妇呼吸运用依从性及顺产率，缩短产程，减轻分娩疼痛，减少产后2h出血量。

Effect of Pre-delivery Respiratory Control Training on Delivery: a Clinical Observation

Objective To investigate the influence of pre-delivery respiratory control training on delivery. Methods Total 190 primipara at 35-36 weeks gestation were randomly divided into experimental group（ n = 100） and control group （ n = 90） ; those in the experimental group received expiratory-centered respiratory control training during 35 to 36 weeks gestation. The compliance rate of respiratory control, uneventful delivery rate, pain score, course of labor, postpartum 2 h- hemorrhage and premature birth rate were compared between the 2 groups. Results There were significant differences in the compliance rate of respiratory control, uneventful delivery rate, amniotic fluid contamination （ Ⅱ -Ⅲ ）, the course of labor, pain score and postpartum hemorrhage between the 2 groups （ P 〈0.05） ; the premature birth rate, premature rupture of fetal membrane and neonatal asphyxia were similar between the 2 groups（ P 〉0.05）. Conclusion Prenatal respiratory control training can improve the compliance of respiratory control, shorten the course of labor, and reduce labor pain and postpartum hemorrhage.
