Correlations among central venous pressure,inferior vena cava collapsibility index and right ventricular function in patients with pulmonary hypertension in intensive care unit
Objective:To analyze correlations among central venous pressure(CVP),inferior vena cava collapsibility index and right ventricular function in patients with pulmonary hypertension in intensive care unit(ICU).Methods:A prospective study was conducted on 63 patients with pulmonary hypertension admitted to the ICU of the hospital from January 2020 to March 2022.According to different pulmonary artery pressure,they were divided into moderate to severe group(n=30)and mild group(n=33).Another 30 healthy subjects were selected as the control group.CVP and inferior vena cava collapse rate were measured in all subjects.The right heart function[cardiac output(CO),tricuspid annulus systolic displacement,tricuspid annulus systolic velocity]was evaluated by pulse indicator continuous cardiac output monitoring(PICCO).Pearson correlation test was used to analyze the correlations among CVP,inferior vena cava collapsibility index with right ventricular function in the patients with pulmonary hypertension in ICU.Results:The levels of CVP and inferior vena cava collapsibility index in the moderate to severe group were higher than those in the mild group and the control group,those in the mild group were higher than those in the control group,and the differences were statistically significant(P<0.05).The levels of CO,tricuspid annulus systolic displacement and tricuspid annulus systolic velocity in the moderate and severe group were lower than those in the mild group and the control group,those in the mild group were lower than those in the control group,and the differences were statistically significant(P<0.05).Pearson correlation analysis showed that the inferior vena cava collapse index,CVP level were positively correlated with CO,tricuspid annular systolic displacement and tricuspid annular systolic velocity in the ICU patients with pulmonary hypertension(r>0,P<0.05).Conclusions:The inferior vena cava collapse index,CVP level are positively correlated with CO,tricuspid annular systolic displacement and tricuspid annular systolic velocity in the patients with pulmonary hypertension in ICU.
