足月妊娠羊水过少患者不同分娩方式的观察

Pregnancy outcomes of different delivery patterns with oligohydramnios at term

对我院2005年、2006年及2010年因羊水过少住院分娩产妇290例进行回顾性分析。其中2005年无引产剖宫产50例,2006年采用控释地诺前列酮栓促宫颈成熟及引产,2010年采用控释地诺前列酮栓或双球囊导管促宫颈成熟及引产。2年中引产后剖宫产29例,引产后阴道分娩122例。结果显示:①我院2005年、2006年及2010年羊水过少患者的剖宫产率分别为83%、57%和37%,其中无引产剖宫产率分别为52%、22%和7%,差异均有统计学意义(P<0.01)。②羊水过少患者中无引产剖宫产、引产后剖宫产及引产后阴道分娩的产后出血率分别为8%、3%和3%,差异无统计学意义,但24 h平均失血量的差异有统计学意义(P<0.05)。

Total of 290 oligohydramnios women were admitted to deliver in our hospital in 2005, 2006 and 2010. From 2006, we began to use dinoprostone vaginal inserts for cervical ripening and induction of labour, and used double-balloon catheters from 2010. In 2005 there were cesarean section（CS） 50 cases of without induction of la- bor, and in 2006 and 2010 29 cases of cesarean section after induction of labor and 122 cases of vaginal delivery af- ter induction of labor. Results showed that （1） The CS rate （CSR） of oligohydramnios women decreased from 2005, 2006 to 2010 （83% , 57% and 37% respectively, P 〈 0.01 ） , and the rate of CS without induction of labour （CWIL） decreased significantly （52%, 22% and 7% respectively, P 〈 0. 01 ）. （2） The volume of postpartum blood loss during CWIL was the highest, which compared with CS after induction of labour （CAIL） and vaginal de- livery after induction of labour （VAIL） was significantly different （P 〈 0. 05 ）.
