目的:讨论人工流产对胎盘的影响,分析既往流产史对再次妊娠分娩的影响。方法:对初孕有人工流产史300例(观察组)与初孕无人工流产史300例(对照组)人工流产与胎盘异常关系进行比较分析。结果:两组胎盘异常发生率有统计学差异(P<0.01)。结论:人工流产致胎盘异常发生率增高,应加强对初孕人工流产进行控制及指导。
OBJECTIVE: To discuss the effect of induced abortion on placenta and to analyze the effect of past abortion history on second trimester pregnancy and childbirth. Methods: The relationship between induced abortion and placenta was analyzed in 300 cases of abortion history in the first trimester (observation group) and 300 cases of no abortion in the first trimester (control group). Results: There was a significant difference in the incidence of placental abnormalities between the two groups (P <0.01). Conclusion: The incidence of abnormal placenta abortion caused by induced abortion is increasing. The control and guidance of induced abortion should be strengthened.
