【摘要】 目的 探讨延期妊娠的结局及防治。 方法 回顾性分析2008年6月-2009年6月收治的1 157例延期妊娠临床资料，根据妊娠时段分A、B、C三组，A组449例，妊娠40+1~40+3周；B组358例，妊娠40+4~40+6周；C组350例，妊娠41~41+6周。比较各组羊水粪染发生率，剖宫产率，新生儿转归情况。 结果 随妊娠时段的延长，羊水粪染发生率，剖宫产率具有统计学意义的变化（P lt;0.05）。新生儿评分低，转专科治疗的新生儿增多。 结论 延期妊娠为高危妊娠，应加强监护及检测手段，适时终止妊娠。
【Abstract】 Objective To explore the outcome of prolonged pregnancy and treatment. Methods Clinical data of 1 157 cases of prolonged pregnancy were retrospectively analyzed during June 2008 to June 2009.They were divided into three groups according to the time of pregnancy.Group A: 449 cases, pregnant age 40+1 - 40+3 week; Group B:358 cases, pregnant age 40+4 - 40+6 weeks; Group C:350 cases, pregnant age 41 - 41+6 weeks. The incidence of amniotic fluid turbidity, the rate of cesarean section and the neonatal prognosis were compared among three groups. Results With the extension of time of pregnancy, the incidence of amniotic fluid turbidity and the rate of cesarean section were statistically different among three groups (P lt;0.05), neonatal score was low, and the number of cases who needed specialist treatment increased. Conclusion Prolonged pregnancy is a high-risk pregnancy.The monitoring and detection means for prolonged pregnancy should be strengthened.Termination of pregnancy should be considered if necessary.
