目的对前置胎盘类型、阴道出血情况及妊娠状况做全面系统了解。方法将72例前置胎盘分轻度组及重度组,对其临床表现及妊娠结局做回顾性分析。结果重度组初次出血及诊断时孕周明显小于轻度组,而产前出血发生率、出血次数差异无统计学意义(P>0.05)。结论期待治疗和采用放宽剖宫产指征,是处理前置胎盘,降低围生儿病死率最关键要点。 Objective To conduct a comprehensive and systematic understanding of the type of placenta previa, vaginal bleeding and pregnancy status. Methods 72 cases of placenta previa were divided into mild group and severe group, and their clinical manifestations and pregnancy outcomes were analyzed retrospectively. Results In the severe group, the initial hemorrhage and gestational weeks at the time of diagnosis were significantly less than those in the mild group. There was no significant difference in the incidence of hemorrhage and the number of hemorrhage between the two groups (P> 0.05). Conclusion It is the most important point to deal with placenta previa and to reduce the rate of perinatal mortality by looking forward to treatment and adopting cesarean indications.
