ABSTRACT
Objective: In critically ill intensive care unit patients, the link between central venous pressure (CVP) readings and ultrasound measurements of the inferior vena cava diameter and collapsibility index was investigated. Methods: This prospective, observational study included 90 patients aged 18 to 65 years of either sex, ASA II-III, admitted to the ICU (intensive care unit) of ALzahraa teaching hospitals with a working central venous catheter implanted for any clinical indication. Hemodynamic measurements were taken on a regular basis, such as non-invasive mean arterial blood pressure. When the CVP (central venous pressure) measurements were performed, the patient was in a supine position. The maximum and minimum collapsibility indexes are then determined using ultrasonography to measure the diameter of the IVC (inferior vena cava). The association between CVP and the IVC collapsibility index was assessed using Spearman's correlation coefficients. Results: In our study, there was a significant correlation between CVP and the two studied ultrasound parameters, IVC CI and IVCdmax. According to the receiver operating characteristic curve (ROC), the inferior vena cava collapsibility index (IVC CI) had the best performance of the two ultrasonography measures in predicting CVP 10 cm H2O, according to the receiver operating characteristic curve (ROC). Conclusions: The collapsibility index of IVC and CVP were discovered to have a strong negative connection in this study. This finding suggests that the IVC collapsibility index could be used instead of CVP to determine the intravascular volume status.
