目的系统研究妊娠相关性血小板减少症的临床特征。方法回顾分析了该院2003年1月～2004年12月住院分娩的52例妊娠相关性血小板减少症(PAT)孕妇临床表现、血小板减少程度与出血的关系、分娩方式与出血量的关系以及分娩后血小板的恢复情况。结果52例PAT孕妇87%(45/52例)属于轻度血小板减少(50-99×109/L),一般无明显自发出血、剖宫产与自然分娩两种方式出血量比较无显著差别,产后血小板在2～12周恢复正常。结论PAT诊断首先应排除其他原因引起的血小板减少,轻度血小板减少PAT可自然分娩,血小板计数<20×109/L,应输注单采血小板并采取剖宫产分娩。
Objective To study the clinical features of pregnancy-related thrombocytopenia. Methods The clinical manifestations, the relationship between thrombocytopenia and hemorrhage in 52 pregnant women with hospitalization and delivery during January 2003 to December 2004 in our hospital were analyzed retrospectively. The relationship between the mode of delivery and the amount of bleeding and the relationship between labor and delivery After the recovery of platelets. Results In the 52 cases of PAT, 87% (45/52) were mild thrombocytopenia (50-99 × 109 / L), with no obvious spontaneous bleeding. There was no significant difference in bleeding between cesarean section and spontaneous delivery. Postpartum platelets returned to normal in 2 to 12 weeks. Conclusion PAT should first rule out other causes of thrombocytopenia, mild thrombocytopenia PAT spontaneous delivery, platelet count <20 × 109 / L, should be infused single platelet collection and cesarean delivery.
