持续性枕横位枕后位是头位难产的重要原因之一。过去对头位难产多以手术结束分娩。随着围产医学的发展,人们对剖宫产的并发症认识逐步提高和重视,要保障母体健康、降低头位难产发生率,我们对80例枕横位枕后位施行经阴道徒手旋转,使难产变为顺产,成功率达90％,效果明显。现报告如下:1 临床资料1.1 一般资料:1997年～1998年2年间,我院分娩总数873例中,头位难产159例,其中80例经阴道徒手旋转,成功72例,失败8例,成功率90％。孕妇年龄22～28岁,平均25岁。初产妇76例,经产妇4例,枕横位50例,枕后位30例。宫口扩张情况:宫口开大4cm～6cm27例,7cm～9cm50例,宫口开全者3例。先露位置:先露-1～-2者29例,0～+1者42例,+2以下者9例。1.2 必备条件:(1)头盆评分≥7分,除外严重头盆大小不称,如骨盆狭窄、畸型、额位等;(2)宫颈扩张进入活跃期出现延 Persistent occipital position occiput posterior position is one of the important reasons for head dystocia. In the past on the first bit more labor to end the delivery of labor. With the development of perinatal medicine, people gradually understanding and understanding of the complications of cesarean section, to protect the health of maternal and reduce the incidence of head dystocia, we 80 cases of occipito-occipital posterior position via vaginal hand rotation, The dystocia became spontaneous, the success rate of 90%, the effect is obvious. The report is as follows: 1 Clinical data 1.1 General information: 1997 ~ 1998 2 years, the total delivery of our hospital 873 cases, the first bit of labor in 159 cases, of which 80 cases of vaginal rotation by hand, 72 cases of success, failure in 8 cases, the success Rate of 90%. Pregnant women aged 22 to 28 years old, average 25 years old. 76 cases of primipara, 4 cases of mothers, 50 cases of occipital transverse position, posterior occipital position in 30 cases.
