妊娠合并血小板减少89例临床分析

目的探讨妊娠合并血小板减少的病因、治疗及分娩方式。方法回顾性分析我院2006年1月-2009年3月收治的89例妊娠合并血小板减少患者的临床资料。结果妊娠期血小板减少的主要病因有妊娠相关性血小板减少症（PAT）65例（73．03％），妊娠期高血压疾病（HDCP）11例（12．36％），特发性血小板减少性紫癜（ITP）6例（6．74％），妊娠合并肝脏疾病5例（5．61％），系统性红斑狼疮合并妊娠2例（2．24％）。PAT孕期不需特殊处理，妊娠结局良好，对血小板〈50×10^9／L的12例患者分娩前给予地塞米松10～20mg／d，5例无效者分娩时输注血小板。结论妊娠期血小板减少以PAT多见，孕期不需特殊处理。其次为妊娠期高血压疾病（HDCP）。当血小板≤50×10^9／L分娩前给予地塞米松治疗，静脉点滴3—5d，无效者分娩时输注血小板，分娩方式以剖宫产为宜，产后出血发生率12．35％。
