目的 探讨前置胎盘的类型、阴道出血状况与妊娠结局的关系。方法 将 89例前置胎盘分为轻度组 ( 4 3例 )及重度组 ( 4 6例 ) ,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均明显小于轻度组 (P <0 0 5) ;而产前出血发生率、出血次数及大出血例数无显著性差异 (P >0 0 5)。有产前出血者其诊断及分娩时的孕周、新生儿体重均显著低于无出血者 ( P <0 0 1 ) ;急诊剖宫产率显著高于无出血者(P <0 0 1 )。结论 前置胎盘患者妊娠结局有很大的差异 ,没有典型的临床特征可循。其类型及产前出血状况不能预测其结局 ,也不能据此提前做出处理方案。
Objective To investigate the relationship between placenta previa, vaginal bleeding and pregnancy outcome. Methods 89 cases of placenta previa were divided into mild group (43 cases) and severe group (46 cases). The clinical manifestations and pregnancy outcome were retrospectively analyzed. Results In the severe group, the initial hemorrhage and gestational week at the time of diagnosis were significantly less than those in the mild group (P <0.05). However, there was no significant difference in the incidence of hemorrhage, the number of hemorrhage and the number of major hemorrhage (P> 0.05). The gestational weeks and newborns with prenatal hemorrhage had significantly lower body weight at diagnosis and childbirth than those without hemorrhage (P <0.01). The rate of emergency cesarean section was significantly higher than that without hemorrhage (P <0.01) . Conclusion The placenta previa patients have great differences in pregnancy outcome, there is no typical clinical features to follow. Its type and prenatal bleeding can not predict its outcome, nor can it be made in advance of treatment options.
