Correlation between Central Venous pressure and Inferior Vena Cava Diameter for Fluid assessment in patients with Chronic Obstructive Pulmonary Disease

Abstract

Background: Chronic obstructive pulmonary disease (COPD) is now the third leading cause of death globally.3 Although COPD primarily affects the lungs, it is now also recognized as a complex multi-component disease characterized by chronic systemic inflammation that frequently coexists with other conditions known as co morbidities. Objective: To determine the correlation between central venous pressure (CVP) and the IVC collapsibility index for estimating the fluid status in COPD patients. Patients and Methods: After obtaining the approval of the Ain Shams University Ethical Committee and written informed consent, 20 patients aged 21 - 60 years of either sex, admitted in the ICU of Ain Shams teaching hospitals who have a functioning central venous catheter inserted for any clinical indication, were involved in this correlational study. CVP measurements were taken with the patient in the supine position from the zero point and the middle line. Results: The current study showed that there was no statically significant correlation Between CVP (cmH2O) and Heart Rate (beat /min), MABP (mmHg), IVCd max (cm) and IVC CI % at Baseline, After PLR test, After Bolus fluid administration, After 3 hours and After 6 hours. Conclusion: The measurement of the IVC diameter has a good correlation with CVP and useful for assessment of the volume status. The measurement of the IVC by ultrasonography may be an important additional evaluation of critically ill patients. Keywords: Chronic obstructive pulmonary disease, central venous pressure
