【摘要】 目的 探討延期妊娠的結局及防治。 方法 回顧性分析2008年6月-2009年6月收治的1 157例延期妊娠臨床資料，根據(jù)妊娠時段分A、B、C三組，A組449例，妊娠40+1~40+3周；B組358例，妊娠40+4~40+6周；C組350例，妊娠41~41+6周。比較各組羊水糞染發(fā)生率，剖宮產(chǎn)率，新生兒轉歸情況。 結果 隨妊娠時段的延長，羊水糞染發(fā)生率，剖宮產(chǎn)率具有統(tǒng)計學意義的變化（Plt;0.05）。新生兒評分低，轉專科治療的新生兒增多。 結論 延期妊娠為高危妊娠，應加強監(jiān)護及檢測手段，適時終止妊娠?！続bstract】 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 (Plt;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.
