摘要 目的研究慢性肺源性心脏病急性加重期(AECCP)患者血液凝固状态与动脉血气的相关性及其对预后的影响,并探讨其可能机制。方法对AECCP住院患者血小板计数(Pit)、凝血酶原时间(PT)、活化部分凝血活酶时间(APIrr)、纤维蛋白原(Fib)、凝血酶时间(TT)的水平和动脉血酸碱度(pH)、氧分压(PaO2)、二氧化碳分压(PaCO2)、实际碳酸氢根(nco;)作回顾性分析,并与30例正常人比较,探讨AECCP患者血液凝固状态与动脉血气的量变关系及其对预后的影响。结果患者PT、APTr、Fib、Tr水平高于正常人(P〈0.001);呼吸衰竭发生率为72.3%,其中I型呼吸衰竭19.O%,低于Ⅱ型呼吸衰竭(53.3%)(P〈0.001);酸血症发生率为37.9%,高于碱血症(10.8%)(P〈0.001);死亡组pH、Plt水平低于生存组(P〈0.05);PaC02、HC03-水平高于生存组(P〈O.01,P〈0.05);pH、Ph预计患者生存机会的ROC曲线下面积(AUC)分别为0.641(95% CI:0.536—0.745;P〈0.01)和0.620(95%CI:0.523-0.718;P〈0.05);PaCO,、HC03-预计死亡风险的ROC曲线AUC分别为0.634(95% CI:0.534—0.734;P〈0.01)和0.625(95%CI:0.524~0.727;P〈0.05)。ptt与Pll水平呈正相关,与PaCO2、HC03-水平呈负相关;Plt与Fib呈正相关,与胛呈负相关。结论易栓状态、出血倾向、低氧血症、高碳酸血症和酸中毒通常同时存在于AECCP患者当中;凝血功能紊乱和呼吸功能障碍严重程度密切相关;Plt、pH、PaCO2、HCO3-水平可作为判断AECCP患者预后的指标。
