摘　　要：目的探讨人工流产后再次妊娠时间与胎盘粘连及产后出血的关系。方法对我院2007年至2009年间住院分娩并具有人工流产史的792例产妇人工流产后再次妊娠时间、胎盘粘连、产后出血的资料进行分析。结果人工流产后0-3月内再次妊娠与人工流产后3-6月内再次妊娠者,胎盘粘连和产后出血的发生率有显著差异。（P〈0.01）;人工流产后3-6月内再次妊娠者与人工流产后6-12月内再次妊娠者,胎盘粘连、产后出血发生率有较显著差异（P〈0.05）;人工流产后6-12月内再次妊娠与12月以后再次妊娠者,胎盘粘连、产后出血发生率无显著差异（P〉0.01）。结论人工流产后再次妊娠时间间隔越短,胎盘粘连、产后出血发生率越高。Objective Discussion of relationships between the gestation time post-abortion and placental adherence and postpartum hemorrhage. Method Analysis of data on the gestation time post-abortion, placental adherence and postpartum hemorrhage of 792 cases of parturients who delivered in hospital between 2007 and 2009 and had a history of induced abortion. Results Comparison between gestation within 3 months post- abortion and gestation within 3-6 months post-abortion, there is a significant deviation of incidence rate of placental adherence and postpartum hemorrhage,（P〈0.01）. Comparison between gestation within 3-6 months post-abortion and gestation within 6-12 months post-abortion, there is a relative significant deviation of incidence rate of placental adherence and postpartum hemorrhage,（P〈0.05）. Comparison between gestation within6-12 months post-abortion and gestation over 12 months post-abortion, there is no significant deviation of incidence rate of placental adherence and postpartum hemorrhage,（P〉0.01）.Conclusion the shorter the intervals between post-abortion and re-gestation, the higher the incidence rate of placental adherence and postpartum hemorrhage.
