【摘要】 目的　探讨体外受精 胚胎移植 (invitrofertilizationandembryotransfer,IVF ET)后妊娠妇女的产科结局。方法　采用回顾性分析方法 ,对IVF ET后妊娠妇女 12 8例 (观察组 )与 11372例自然妊娠妇女 (对照组 )的产科结局进行比较。结果　观察组早产发生率为 2 0 .3% (2 6 /12 8) ,多胎发生率为 2 0 .3% (2 6 /12 8) ,妊娠高血压综合征 (妊高征 )发生率为 14.8% (19/12 8) ,低出生体重儿发生率为2 5 .5 % (41/16 1) ,剖宫产率为 88.3% (113/12 8) ,围产儿死亡率为 31.1‰ (5 /16 1) ;而对照组分别为3.3% (380 /11372 )、1.0 % (119/11372 )、7.6 % (86 3/11372 )、3.6 % (416 /11492 )、34 .7% (3946 /11372 )、8.9‰ (10 2 /11492 ) ,两组比较 ,差异有显著性。结论　IVF ET后妊娠妇女的产科并发症明显增高 ,多胎妊娠为一重要的高危因素更多还原

【Abstract】 Objective To evaluate the obstetrical outcome of in vitro fertilization and embryo transfer (IVF ET) pregnancy. Methods This study compared the obstetrical outcome of 128 cases of IVF ET pregnancy with that of 11 372 natural pregnancies as control group. Results There were 20.3%(26/128) multiple pregnancy, 20.3%(26/128) premature birth, 14.8%(19/128) pregnancy induced hypertension, 25.5%(41/161) small for gestational age, 88.3%(113/128) cesarean section rate and 31.1‰(5/161) perinatal mortality in the IVF ET group. However, these data in the control group were 3.3%(380/11 372),1.0%(119/11 372), 7.6% (863/11 372),3.6%(416/11 492),34.7%(3 946/11 372)and 8.9‰(102/11 492), respectively. Conclusion The incidence of obstetrical complications was significantly higher in IVF ET pregnancy. Multiple pregnancy is a high risk factor.更多还原
