目的:探讨延期妊娠的妊娠结局及处理策略。方法:回顾性分析2005年1月至2007年12月间在我院妇产科住院治疗的111例延期妊娠病人的临床资料,并随机抽取同期我院收治的111例足月妊娠病例资料,两组相对比。结果:延期妊娠使胎盘成熟度Ⅲ级、羊水过少、羊水污染、胎儿窘迫、新生儿窒息、阴道助产、剖宫产等发生率明显增高(P<0.05),两组间巨大儿、低体重儿发生率无显著差异(P>0.05)。结论:延期妊娠使胎盘功能减退,胎儿对缺氧的耐受性降低,高危程度增加,故产前产时需严密监护,为保全胎儿多采取剖宫产术结束妊娠。
Objective: To investigate the pregnancy outcome and treatment strategy of delayed pregnancy. Methods: A retrospective analysis of clinical data of 111 cases of deferred pregnancy in our hospital from January 2005 to December 2007 were retrospectively analyzed. A total of 111 cases of full-term pregnancy treated in our hospital during the same period were selected. Group comparison. Results: Delayed pregnancy increased the placental maturity grade III, oligohydramnios, amniotic fluid contamination, fetal distress, neonatal asphyxia, vaginal delivery and cesarean section (P <0.05) No significant difference in the incidence of weight children (P> 0.05). CONCLUSION: Delayed pregnancy reduces placental function, and fetal tolerance to hypoxia is reduced and the high-risk degree is increased. Therefore, prenatal labor should be closely monitored, and cesarean delivery should be completed to protect the fetus.
