目的：分析产程中应用手-膝俯卧位对产妇的妊娠结局。方法选择2014年01月~12月在本院住院选择自然分娩的低危初产妇120例为研究对象，随机将产妇分为研究组与对照组，每组各60例，研究组在第二产程初应用手-膝俯卧位，对照组应用平卧位，观察两组产程进展和会阴裂伤、会阴侧切、产后出血、产后尿潴留、新生儿窒息等母婴结局。结果研究组比对照组，第二产程时间短，有更少的会阴侧切(0.05)。结论俯卧位缩短第二产程，降低产后尿潴留发生，不增加新生儿窒息，降低会阴损伤，提高母亲舒适度，促进自然分娩，是值得推荐应用的分娩体位。“,”Objective Analysis on Maternal and neonatal outcomes of hands-and-knees position during labour.Methods A total of 120 primiparae from January 2014 to December 2014 were assigned into study group (n=60cases)and control group (n=60 cases).The study group lied on hands-and knees while the control group lied on back during labour.laboring process,perineal lacerations, incision of lateral episiotomy,postpartum hemor hage,postpartum retention of urine,neonatal asphyxia rates were observed.Results The study group showed shorter the second stage of labour,lighter perineum episiotomy,less postpartum retention of urine ( 250mL and neonatal asphyxia.Conclusion On hands-and-knees can help to shorten the second stage of labor,and decrease postpartum retention of urine without increasing neonatal asphyxia,thus it is worth for application in clinical work.
