摘　　要：【目的】探讨重症心力衰竭有创通气患者周围静脉压(PVP)与中心静脉压(CVP)的相关性和一致性。【方法】选择2021年1月至12月在重症监护病房接受有创通气的重症心力衰竭患者为研究对象,所有患者首次测量CVP时,均经肘正中或贵要静脉同步测量PVP,采用Pearson相关性分析CVP与PVP相关性,采用Bland-Altman方法分析CVP与PVP一致性。【结果】Pearson相关性分析显示,CVP与PVP呈正相关(r=0.93,P<0.05)。直线回归方程为y=0.98 x-0.44(y为CVP,x为PVP;F=846.02,P<0.05),校正决定系数R 2=0.87。138例患者,CVP测量值为(11.53±5.70)mmHg,PVP测量值为(12.28±5.46)mmHg,95%一致性限度为-4.8~3.3 mmHg。Bland-Altman分析显示,CVP与PVP一致性较好。【结论】PVP与CVP相关性、一致性好,对于接受有创通气的心力衰竭患者而言,PVP与CVP是一种快速、可靠、无创的容量状态评估指标。【Objective】To investigate the correlation and consistency between peripheral venous pressure and central venous pressure in patients with severe heart failure with invasive ventilation.【Methods】Patients with severe heart failure who received invasive ventilation in the intensive care unit from January to December 2021 were selected as the study subjects.When central venous pressure(CVP)was measured for the first time in each patient,peripheral venous pressure(PVP)was measured simultaneously through the median of the elbow or the main vein.Pearson correlation analysis was used to analyze the correlation between CVP and PVP.Bland-Altman method was used to analyze the consistency of CVP and PVP.【Results】Pearson correlation analysis showed that there was significant linear correlation between CVP and PVP(r=0.93,P<0.05).The linear regression equation was y=0.98 x-0.44(y was CVP,x was PVP;F=846.02,P<0.05),calibration determination coefficient R 2=0.87.In 138 patients,the measured values of CVP and PVP were(11.53±5.70)mmHg and(12.28±5.46)mmHg,and the 95%conjunctive limit was from-4.8 mmHg to 3.3 mmHg.Bland-Altman analysis showed that CVP had good consistency with PVP.【Conclusion】PVP and CVP have good correlation and consistency.For patients with heart failure receiving invasive ventilation,PVP and CVP are a rapid,reliable and non-invasive assessment index of volume status.
