摘要 目的 :评价脓毒症患者脉搏灌注变异指数(PVI)和中心静脉压(CVP)、平均动脉压(MAP)及中心静脉氧饱和度(Scv O2)的相关性。方法 :选择老年脓毒症患者29例,行中心静脉置管,测CVP,留取中心静脉血测Scv O2,测无创动脉血压,计算MAP=舒张压+1/3(收缩压-舒张压),同步采用Masimo Radical 7脉搏血氧仪测量PVI及脉搏氧灌注指数(PI)。结果:PVI与CVP、PVI与Scv O2均呈显著负相关(分别为r=-0.622,P<0.01和r=-0.784,P<0.01),PVI与MAP呈轻度负相关(r=-0.299,P<0.05)。结论:PVI在老年脓毒症患者的容量复苏评价中与CVP、Scv O2及MAP有良好的相关性。
