引产对孕41周孕妇的母儿结局影响

目的 探讨引产对孕41周、无妊娠合并症孕妇母儿结局的影响.方法 选择北京协和医院妇产科2002年9月至2007年4月收治的孕41-41周+0、无妊娠合并症的初产妇374例,按临产与否分为引产组225例,其中药物(包括应用缩宫素和地诺前列酮)引产173例,人工破膜引产5例,人工破膜+药物引产47例;自然临产组149例.分别对两组孕妇的一般情况、分娩方式、产后并发症、新生儿窒息发生情况、住院天数及费用等进行回顾性分析.结果 (1)引产组的剖宫产率(44.0%,99/225)明显高于自然临产组(18.1%,27/149),两组比较,差异有统计学意义(P<0.05).(2)引产组及自然临产组产后出血发生率分别为2.7%(6/225)和1.3%(2/149)、产褥病率分别为0.9%(2/225)和0.7%(1/149)、切口延期愈合发生率为0.9%(2/225)和0.7%(1/149)、尿潴留发生率分别为4.4%(10/225)和3.4%(5/149)、产时损伤发生率分别为0.4%(1/225)和0、羊水Ⅲ度污染发生率分别为11.6%(26/225)和13.4%(20/149)、新生儿窒息发生率分别为1.3%(3/225)和2.0%(3/149),两组孕妇以上各指标分别比较,差异均无统计学意义(P>0.05).(3)在阴道顺产中,第一产程时间引产组平均为413 min,自然临产组平均为461 min,两组比较,差异无统计学意义(P>0.05);第二产程时间引产组平均为40 min,自然临产组为48 min,两组比较,差异有统计学意义(P<0.05);引产组阴道顺产中第二产程超过60 min的发生率为17.1%(20/117),自然临产组为28.8%(34/118),两组比较,差异有统计学意义(P<0.05);引产组急产发生率为5.1%(6/117),自然l临产组为0,两组比较,差异有统计学意义(P<0.05).(4)住院天数自然临产组平均为(5.7±1.9)d,引产组为(6.9±2.7)d,两组比较,差异有统计学意义(P

Effect of induction delivery on maternal-neonatal outcomes in 41 gestational weeks primiparae

Objective To estimate the maternal.neonatal morbidity associated with induction deliveries compared with spontaneous deliveries in 41 gestational weeks uncomplicated primiparae.Methods Three hundred and seventy.four uncomplicated primiparous deliveries at 41 gestational weeks at Peking Union Medical College Hospital from Sept 2002 to Apr 2007 were reviewed.including 225 women undergoing induced labor and 149 women undergoing spontaneous labor.The induction methods included drug induction (173),rupture of membrane induction(5)and combined drug with rupture of membrane induction(47).The maternal morbidity,delivery method,matemal cost on hospital stay and neonatal asphyxia associated with induction deliveries or spantaneous deliveries were retrospectively analyzed.Results (1)There was no maternal death.The caesarean section rate in the induction group(44.0%,99/225)was significantly higher than that of spontaneous group(18.1%,27/149;P<0.05).(2)No statistically significantdifference(P>0.05)was observed between induction group and spontaneous group in the following puerperal complications:postpartum hemorrhage(2.7%,6/225 and 1. 3%,2/149 respectively),puerperal morbidity(0.9%,2/225 and 0.7%,1/149 respectively),severe amniotie fluid contamination (11.6%,26/225 and 13.4%,20/149 respectively),wound infection(0.9%,2/225 and 0.7%.1/149 respectively),urinary retention(4.4%,10/225 and 3.4%,5/149 respectively),traumata(0.4%,1/225and 0 respectively)and neonatal asphyxia(1.3%,3/225 and 2.0%,3/149 respectively).(3)The average duration of first stage of labor in the induction group(413 min)Was not significantly different from tllat of spontaneous group(461 min;P>0.05).In the induction group,more women had precipitate lahore(P
