持续性枕横位(DTA)及持续性枕后位(POPP)占头位难产的首位。对枕横位及枕后位的早期发现并及时加以纠正可使大部分难产转为顺产,从而降低剖宫产率、胎儿宫内窘迫或新生儿窒息的发生率。我们就本院持续性枕横位及枕后位208例诊断及处理进行回顾性分析如下。资料与方法一、一般资料自1993年1月~1995年12月总分娩数为1767例,头位单胎数为1629例,其中行剖
Persistent occipito axial position (DTA) and persistent posterior occipital position (POPP) accounted for the first place of head-dystocia. The early detection and timely correction of the occiput posterior position and posterior occipital position can turn most of the dystocia to normal, thus reducing the incidence of cesarean section, fetal distress or neonatal asphyxia. We retrospectively analyzed the diagnosis and treatment of 208 consecutive cases of occipito-occipital and posterior occiput in our hospital. Materials and Methods I. General Information The total number of deliveries from January 1993 to December 1995 was 1767 and the number of singletons at the head was 1629. Among them,
