一、脓毒症血流动力学管理的意义及关键 从脓毒症的病理生理机制出发,脓毒症血流动力学管理具有非常重要的意义。通过优化液体治疗,增加每搏输出量(stroke volume,SV),改善脏器灌注,减少脏器损伤。在整个液体治疗过程中,必须关注循环系统的几个环节,即容量(前负荷)、心脏泵功能(收缩和舒张功能)、血管张力(后负荷),这三个环节缺一不可,这样才能真正纠正脓毒症病理生理的恶化。 二、脓毒症血流动力学监测指标 三、个体化脓毒症液体管理 当进入第二阶段,符合Sepsis 3.0诊断,患者会出现一系列脏器损伤,血乳酸进一步升高,甚至出现代谢性酸中毒,此时如果按照脓毒症集束化治疗策略及时进行液体治疗,患者仍会有良好的液体反应性。 参考文献 [1] Marik P E, Baram M.
