Objective To study the relationship between induced abortion and placental adherence, reduce placental adhesion rate. Methods A retrospective analysis was performed on parturient in our hospital from January 2006 to January 2009. Results There were 70 cases of placental adherence in 3296 parturients during the 3 years, and the incidence rate of placenta accreta was 2. 1％ , with an increasing rate year after year. 3296 case were divided into two groups: abortion group ( n = 964 ) and uninduced abortion group ( n = 2332 ). There were 56 cases of placental adherence in abortion group, accounting for 5.8％ , and 14 cases of placental adherence in uninduced abortion group, accounting for 0. 6％. There was significant difference of incidence rates between the two groups( x2 = 83.59, P ＜ 0.0l ). Further analysis found that there was significantly positive correlation between the occurrence of placenta adhesion and induced abortion times(r =0.181 ,P =0.000), and negative correlation between occurrence of placenta adhesion and the time of subsequent pregnancy after abortion ( r = - 0.167, P = 0. 000 ). Conclusion In order to reduce the occurrence of placenta adhesion, we should strictly control abortion indications and contraindications, strengthen sterile conception and improve surgical proficiency, and in addition, postoperative hygine should be enhanced and second time pregnancy shortly after operation should be avoided%目的 探讨胎盘粘连与人工流产术的相关性,以降低胎盘粘连发生率.方法 对我院2006年1月～2009年1月住院分娩产妇发生胎盘粘连的临床资料进行回顾性分析.结果 3年间住院分娩产妇总数3296例,发生胎盘粘连70例,总发生率2.1%,且逐年上升.将3296例分娩产妇分为有人工流产组和无人工流产组.人工流产组964例,发生胎盘粘连56例,发生率5.8%;无人工流产组2332例,发生胎盘粘连14例,发生率0.6%.两组胎盘粘连发生率比较差异有统计学意义(χ2=83.59,P＜0.01).胎盘粘连的发生与人工流产次数呈正相关(r=0.181,P=0.000),与人工流产术后至再次妊娠间隔时间呈负相关(r=-0.167,P=0.000).结论 严格掌握人工流产术的适应证及禁忌证,加强无菌观念,做好术后卫生宣教,避免短期内受孕,从而降低胎盘粘连的发生.
