摘　　要：目的探讨前置胎盘类型、产前出血状况与妊娠结局的关系。方法71例前置胎盘按胎盘位置分为边缘型组(23例)、部分型组(18例)和中央型组(30例),分析其临床表现和妊娠结局。结果中央型组初次出血及诊断孕周均小于其他两组(P<0.05),部分型组与边缘型组无显著差异(P>0.05);产前出血发生率、出血次数及大出血例数三者无显著差异(P>0.05);有产前出血者其诊断及分娩时孕周、新生儿体质量均低于无出血者(P<0.01),急诊剖宫产率显著高于无出血者(P<0.01)。结论前置胎盘的妊娠结局不能以类型来预测。产前出血对急诊剖宫产率、新生儿体质量有一定影响。Objective To investigate the relationship between the types of placenta praevia, antepartum haemorrhage and clinical outcomes. Methods Medical records including outcomes of 71 patients with placenta praevia （23 with marginal praevia, 18 with partia praevia, 30 with total praevia） were reviewed retrospectively. Results The gestational week at first bleeding and diagnosis in total previa group was the smallest in the three groups （P 〈 0.05） , the gestational week at first bleeding and diagnosis in marginal praevia group and partial praevia group showed no significant differences （P 〉 0.05）. The incidence of antepartum haemorrhage, the times of bleeding and the number of patients suffered from severe bleeding in the three groups showed no significant differences （P 〉 0.05）. The gestational weeks at diagnosis and delivery and the birthweight were significantly smaller in patients with antepartum bleeding than those without bleeding （P 〈0.01 ）. The number of emergency caesarean sections in patients with antepartum bleeding was significantly higher than that in non-bleeding patients（P 〈 0.01 ）. Conclusion The pregnant outcome of placenta praevia can＇t be prognosed by the types of placenta praevia. Antepartum haemorrhage affects the incidence of emergency caesarean section and birthweight.
