JCLA:百草枯中毒患者血浆凝血酶原时间延长与预后不良有关

2019-01-18 MedSci MedSci原创

口服百草枯入血后可严重损伤血管内皮细胞,引起凝血功能障碍。在本研究中,研究人员的目的是寻找一种常规凝血指标,作为急性百草枯中毒患者预后的指标。 2012年1月~ 2016年12月,研究人员对209例口服百草枯自杀未遂收治患者开展研究。常规凝血指标包括血浆凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)、纤维蛋白原(Fbg)、凝血酶时间(TT)、D二聚体,分析其变化趋势及其与预后的关系。

口服百草枯入血后可严重损伤血管内皮细胞,引起凝血功能障碍。在本研究中,研究人员的目的是寻找一种常规凝血指标,作为急性百草枯中毒患者预后的指标。

20121~ 201612月,研究人员对209例口服百草枯自杀未遂收治患者开展研究。常规凝血指标包括血浆凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)、纤维蛋白原(Fbg)、凝血酶时间(TT)D二聚体,分析其变化趋势及其与预后的关系。

结果显示,30 mLPTAPTT值均显著高于<30 mL(P< .01)。入院1周内PTAPTT值逐渐降低,Fbg水平逐渐升高。单因素和多因素Cox回归分析表明,性别、摄食量和PT40天内死亡率的独立预测因素。PT <12秒患者与PT 12秒患者的累计生存率差异显著(P = 0.001)

研究结果表明,百草枯中毒患者凝血状态与预后密切相关。常规监测凝血功能,尤其是血浆PT,有助于分析PQ中毒患者的病情和预后。
