重复剖宫产对妊娠结局的影响

目的 探讨重复剖宫产对孕产妇及围产儿结局的影响.方法 回顾性分析1998年1月1日至2007年12月31日,在北京协和医院妊娠超过28周行再(多)次剖宫产手术分娩的产妇共412例,根据剖官产次数分为再次剖宫产组(repeated caesarean section group,RCS组,394例)和多次剖宫产组(multiple caesarean section group,MCS组,18例),随机选取同期行初次剖宫产手术分娩的480例为初次剖宫产组(first caesarean section group,FCS组)作为对照,分析三组孕妇的一般临床资料、产时产后并发症及围产儿结局.结果 近十年我院再次剖官产率为4.1%,呈逐年上升趋势.(1)一般临床资料比较:RCS组及MCS组平均年龄分别为(33.7±4.3)岁,(34.5±5.1)岁,大于FCS组(31.5±4.3)岁(P<0.05).RCS组及MCS组平均孕次分别为(3.5±1.4)次,(4.7±1.5)次,多于FCS组(2.1±1.2)次(P<0.05).(2)盆腔粘连发生率:RCS组及MCS组分别为13.5%和50.0%,高于FCS组(0.4%)(P<0.05).(3)子宫破裂发生率:RCS组(1%)高于FCS组(0%)(P<0.05).(4)RCS组及MCS组平均分娩孕周分别为(38.1±1.8)周,(37.3±2.5)周,与FCS组(38.9±2.1)周]比较差异有统计学意义(P<0.05).结论 再 (多)次剖宫产发生率逐年上升,其显著增加盆腔粘连及子官破裂的发生率,但并不增加围产儿并发症的发生率.

Effects of repeated caesarean section on maternal and neonatal outcomes

Objective To investigate the effects of repeated caesarean section (RCS) on maternal and neonatal outcomes. Methods From January 1998 to December 2007, 412 cases underwent RCS at Peking Union Medical College Hospital were reviewed and divided into two groups based on the number of CSs: RCS group (n= 394) and multiple caesarean section (CS) group (MCS group, n= 18). General conditions, maternal complications and neonatal outcomes were compared among RCS group, MCS group and first CS groups (FCS group) which consisted of 480 women underwent the first CS during the same period. Results The incidence of RCS was 4. 0% with an increasing trend during the past ten years. (1) The mean age of RCS and MCS group were (33.7± 4. 3) yrs and (34. 5±5.1)yrs respectively, higher than FCS group (P<0. 05). The average gravidity in RCS and MCS group were (3.5±1.4), (4. 7±1.5) respectively, higher than FCS group (2.1± 1.2, P<0. 05). (2) The rate of severe pelvic adhesion and uterus rupture were significantly higher in RCS group than in FCS group (13.5% vs 0. 4%, 1% vs 0%, P<0. 05). (3) The mean gestations of RCS group and MCS group were (38.1±1.8)weeks and (37.3±2.5)weeks respectively, while it was (38. 9±2. 1) weeks in the FCS group (P<0. 05). Conclusions RCS rate is growing. Although RCS would increase the incidence of dense adhesion and uterine rupture, it is a relatively safe procedure without increasing the neonatal morbidity.
