目的：探讨初产妇胎盘粘连与既往流产史的关系，分析既往流产史对再次妊娠分娩的主要影响。方法：对经阴道分娩的单胎初产产妇有流产史的９９３例（观察组）和无流产史的６６０例（对照组）从胎盘粘连发生率、流产次数与胎盘粘连的关系，以及胎盘粘连与产后２小时出血量的关系等方面进行比较分析。结果：胎盘粘连的发生率观察组为７９６％，对照组为３７９％，两组之间比较，差异有极显著性意义（χ２＝１１６８，Ｐ＜０００１，ＯＲ＝２１９５）。流产２次组与流产１次和流产３次组比较，差异有显著性意义（Ｐ＜００１）。既往无流产史和有１次、２次以及３次以上流产史的初产妇组，其发生胎盘粘连与产后２小时出血量经方差分析，无流产史组和流产２次组比较有显著性差异，其余各组间的比较Ｐ＞００５。结论：初产妇胎盘粘连与既往有流产史间的关系、流产次数增加与胎盘粘连的发生率间的关系差异均有极显著性意义。无流产史组和有流产史各组的初产妇发生胎盘粘连与产后２小时出血量之间差异有显著性意义，但其组与组之间的差异可能还有待增加例数进一步研究。
Objective: To investigate the relationship between primipara placenta adhesion and past history of abortion, and to analyze the main influence of past abortion history on the second trimester of pregnancy and childbirth. Methods: Ninety-three cases of abortion (observation group) and no abortion history (control group) of single-birth primipara with vaginal delivery were analyzed from the incidence of placenta accreta, the relationship between the number of abortion and placenta adhesion, And 2 hours postpartum bleeding and other aspects of the relationship between the comparative analysis. Results: The incidence of placental adhesion in observation group was 796% and in control group was 379%. There was significant difference between the two groups (χ2 = 1168, P <0001, OR = 2 195). There was significant difference between abortion group 2 and abortion group 1 and abortion group 3 (P <001). Previous abortion history and 1, 2 and 3 abortion history of primipara group, the occurrence of placenta accreta and 2 hours postpartum hemorrhage were analyzed by ANOVA, no abortion history group and miscarriage second group were significantly different , The rest of the comparison between groups P> 0 05. CONCLUSION: The relationship between primipara placenta adhesion and past history of abortion, the relationship between the increase of abortion frequency and the incidence of placenta adhesion have extremely significant significance. There was a significant difference between the first trimester of placenta accreta and the second postpartum amount of bleeding in the abortion group and abortion history group, but the difference between the group and the group may have to be further studied.
