第二产程延长及延长后新生儿窒息的高危因素分析

Analysis of risk factors for neonatal asphyxia prolonged second stage and after prolonged

目的：探讨第二产程延长的原因及延长后导致新生儿窒息的高危因素。方法：筛选2013年1月~2014年1月于我院进行分娩并发生第二产程延长的产妇106例作为研究对象。对所有产妇应用超声进行产前检查观察胎儿体位等情况，分娩过程前观察产妇产道、胎儿体位及胎儿娩出时脐带位置，分析产妇第二产程延长的原因及造成新生儿窒息的高危因素。结果：106例产妇均发生第二产程延长，其中造成第二产程延长的前四位原因为：胎儿体位异常37例（34．91％），产妇宫缩乏力15例（14．15％），脐带位置异常22（20．75％），产道异常14例（13．21％）。其中发生新生儿窒息14例。结论：造成第二产程延长的主要原因为胎儿体位异常、产妇宫缩乏力、产道异常、脐带位置异常，同时胎儿窘迫、脐带位置异常是导致第二产程延长后新生儿窒息的主要因素。

Objective：To investigate the risk factors leading to neonatal asphyxia investigate the cause of prolonged second stage of labor and after prolonged. Methods：Selected second prolonged maternal from January 2013 - January 2014 for the study. Of all maternal prenatal ultrasound examination to observe fe-tal position,etc. ,before the observation of maternal birth canal during delivery,when the umbilical cord fetal position and the position of the fetus,the mater-nal prolonged second stage of analysis of causes and risk factors caused by neonatal asphyxia. Results：106 cases of maternal occurred prolonged second stage of labor,which caused prolonged second stage of the top four reasons as follows：37 cases of abnormal fetal position（34. 91% ）,maternal uterine inertia in 15 cases（14. 15% ）,umbilical cord abnormal position 22（20. 75% ）,abnormal birth canal 14 cases（13. 21% ）. Where 14 cases of neonatal asphyxia. Conclusion：Resulting in prolonged second stage of the main reasons abnormal maternal uterine inertia,birth canal abnormal fetal position,umbilical cord ab-normal position,while fetal distress,cord abnormal position of the main factors leading to the second stage of labor prolonged neonatal asphyxia.
