CORRELATION BETWEEN INFERIOR VENA CAVA SONOGRAPHIC DIAMETER AND CENTRAL VENOUS PRESSURE IN SEPTIC SHOCK
Main Article Content
Abstract
Background: Assessing fluid responsiveness played a crucial role in hemodynamic support for patients with septic shock. The role of inferior vena cava sonographic diameter and correlation of inferior vena cava with central venous pressure have been increasingly mentioned to guide fluid responsiveness. Method: Prospective observational study at emergency department at University medical center. Fluid challenge was performed according to surviving sepsis campaign 2016. A ≥15% increase in stroke volume after fluid challenge was considered as fluid responsiveness. The CVP catheter was placed, and inferior vena cava sonographic diameters were measured before and after the fluid challenge. Results: 96 septic patients with a mean age of 66,5 ±13,5 were enrolled between 07/2020 and 12/2021, all of the patients were mechanically ventilated. APACHE II score 20,2 ± 2,8, SOFA score 7,1 ± 1,3. 38 patients were considered as fluid responders (39,6%). IVC measurements were statistically significantly correlated with CVP measurements, both inspiratory phase (r = 0,97, p < 0,001) and expiratory phase (r = 0,914, p < 0,001). IVC collapsibility measurements showed a negative correlation with CVP measurements (r = -0,49, p < 0,001). Conclusion: There is a strong correlation between CVP and IVC diameters, and ICV diameters may be used to predict CVP.
