医源性早产1823例临床分析

Clinical Analysis of 1823 Cases of Iatrogenic Preterm Birth

目的:研究医源性早产的发生率、发生因素以及分娩方式。方法:回顾性分析了2004年1月至2009年12月四川大学华西第二医院发生的医源性早产1823例。结果:2004年1月至2009年12月,四川大学华西第二医院医源性早产发生率为6.84%,占早产总例数的50.30%。妊娠期肝内胆汁淤积症(ICP)、产前出血、妊娠期高血压疾病是导致医源性早产的前3位因素,分别占医源性早产总数的26.77%、23.64%、19.53%。118例医源性早产由人为因素造成。剖宫产终止妊娠1598例(87.66%)。结论:医源性早产已逐步成为早产的主要原因,人为因素已成为医源性早产的一大原因,剖宫产是医源性早产终止妊娠主要方式,产科医师应严格选择医源性早产终止妊娠的方式。

Objective：To investigate the incidence, causes and delivery methods of iatrogenic preterm la- bor. Methods：1823 cases of iatrogenic preterm labor in theWest China Second University Hospital from Jan- uary 2004 to December 2009 were analyzed retrospectively. Results： From January 2004 to December 2009, the total incidence of iatrogenic preterm birth was 6.84%, accounting for 50.30% of the total recorded preterm births. The top three causes of the iatrogenic preterm birth were intrahepatic cholestasis of pregnan- cy （ICP）, placenta previa and severe pre-eclampsia. 118 pregnancies delivered prior to term were for hu- man factors. 1598 （87. 66% ） iatrogenic preterm births underwent cesarean section. Conclusions：The iatro- genic preterm birth has became the main reason of the preterm birth and the human factor has became an important cause of it. Cesarean delivery is the main delivery method among iatrogenic preterm births. Obste- tricians should choose the delivery method strictly.
