摘要(Abstract)：

目的通过脉搏指示连续心输出量监测(Pi CCO)评价心原性休克患者使用多巴胺治疗后血流动力学变化与住院期间死亡的相关性,进一步探讨使用Pi CCO评价患者预后的可行性。方法将15例接受Pi CCO监测的心原性休克患者分为生存组8例和死亡组7例,收集患者的病史和一般资料,并在基线和多巴胺治疗6 h后测定Pi CCO指标。结果死亡组患者的基线血管外肺水指数(EVLWI)显著高于生存组(9.20 ml/kg比15.40 ml/kg,Z=1.415,P=0.037);多巴胺治疗6 h后,生存组患者的心指数(CI)改善率显著高于死亡组患者(51.13%比8.10%,Z=-2.315,P=0.021);生存组患者全身血管阻力指数(SVRI)显著降低,而死亡组则轻度升高(-27.05%比0.90%,Z=-2.777,P=0.004)。以EVLWI>10.90 ml/kg为界值预测住院期间死亡的敏感性为85.7%,特异性为62.5%;以治疗后SVRI下降率>17.85%为界值预测住院期间死亡的敏感性为85.7%,特异性为75.0%;以治疗后CI增加率<16.16%为界值,预测住院期间死亡的敏感性为71.4%,特异性为87.5%。结论心原性休克患者经多巴胺治疗前的EVLWI水平、治疗后的CI改善程度和SVRI降低幅度可能作为预测住院期间死亡的重要指标,Pi CCO用于实时评价多巴胺治疗前后血流动力学变化具有很高的可行性。
