目的 探讨引起第二产程异常的原因及防治措施。方法 抽取 3家医院 2年间分娩的 10 0 0例产妇 (正常组5 0 0例 ,异常组 5 0 0例 )的分娩记录资料进行回顾性分析。结果 产程异常组的新生儿出生平均体重、胎方位异常、产力异常、脐带异常、剖宫产率以及并发症发生率均显著高于正常组 (P <0 0 5～ <0 0 0 0 1)。结论 在骨盆正常情况下 ,新生儿过大、胎方位异常、产力异常是造成第二产程异常的主要原因 ,脐带过短或脐带绕颈数圈致使胎头下降受阻而造成第二产程延长者为另一重要原因。针对造成产程异常的潜在因素进行对症防治是关键
Objective To explore the causes of abnormalities in the second stage of labor and its prevention and treatment. Methods The data of birth records of 100 maternal births (500 in the normal group and 500 in the abnormal group) were collected from 3 hospitals in two years for retrospective analysis. Results The average birth weight, abnormal fetal position, abnormal output, umbilical cord abnormality, cesarean section rate and complication rate in the abnormal labor group were significantly higher than those in the normal group (P <0 05 ~ <0 0 0 0 1 ). Conclusion In the normal pelvic condition, the newborn is too large and the fetal position is abnormal. The abnormal birth force is the main cause of the second stage of labor abnormality. If the umbilical cord is too short or the umbilical cord is hindered by the number of rings around the neck, Another important reason. Prevent symptomatic control is the key to potential causes of labor abnormalities
