目的分析凶险性前置胎盘的临床特点及对母婴的危害性,进一步提高对凶险性前置胎盘的认识。方法对2012年1月至2014年6月新疆维吾尔自治区人民医院收治的129例凶险性前置胎盘中的中央型组与非中央型组孕产妇相关因素及妊娠结局进行回顾性分析。结果凶险性前置胎盘中央型与非中央型距前次妊娠间隔及发生产前出血时间差异有统计学意义(P<0.05),流产次数、剖宫产次数、术中出血量、弥散性血管内凝血(DIC)发生率、胎盘植入率及子宫切除率比较差异有统计学意义(P<0.05),两组孕妇年龄及新生儿结局差异无统计学意义(P>0.05)。结论凶险性前置胎盘中央型出血量明显高,易发生胎盘植入,发生DIC危及母婴生命安全。在临床实践中,应当严格掌握剖宫产手术相关指征,尽量降低剖宫产率,并做好计划生育,以降低人工流产率,能够有效预防凶险性前置胎盘发生。
Objective To analyze the clinical features of dangerous placenta previa and its harmfulness to mother and infant, and to further raise awareness of dangerous placenta previa. Methods Retrospective analysis was made on the maternal related factors and pregnancy outcomes in 129 cases of dangerous placenta previa from January 2012 to June 2014 in People’s Hospital of Xinjiang Uygur Autonomous Region. Results There were significant differences in the time between the previous pregnancy and the time of prenatal hemorrhage between the central placenta and the non-central precancerous placenta previa (P <0.05), the number of abortion, the number of cesarean section, intraoperative blood loss, disseminated blood vessels The incidence of internal coagulation (DIC), placenta accreta and hysterectomy rates were significantly different (P <0.05). There was no significant difference in the age and neonatal outcomes between the two groups (P> 0.05). Conclusions The risk of central placenta previa placenta was significantly higher, placenta accreta was easy to occur and DIC threatened the safety of mother and infant. In clinical practice, cesarean section should strictly control indications for surgery, cesarean section rate as much as possible and good family planning to reduce the rate of induced abortion, can effectively prevent the occurrence of dangerous placenta previa.
