Abstract

In earlier research, studies were done to evaluate how well CVP was predicted by IVC diameter and collapsibility Index but a direct comparison of the efficacy of both indices for predicting CVP was seldom performed. The purpose of this study is to further characterize the association between IVC diameters, collapsibility index, and central venous pressure (CVP) for determining volume status in critically ill patients, as well as to compare the efficacy of IVC MIN, IVC MAX, and IVCCI for predicting CVP. Methods: A Cross-sectional comparative study was conducted at Department of Anaesthesia, Andhra Medical College, Visakhapatnam, Andhra Pradesh, India, between June 2022 to November 2022. After obtaining approval from the Hospital Ethics committee, and written informed patient content, we studied 50 patients who are critically ill with an intrathoracic central venous catheter that had been already inserted. Results: In this study, the sonographic parameters, such as IVC max and IVC min, demonstrated a strong positive correlation with invasive CVP, indicating that as CVP rises, so too does the value of the aforementioned parameters. The IVC Collapsibility Index demonstrated a strong negative correlation with invasive CVP, indicating that the IVC Collapsibility Index's value decreases as CVP rises. IVC max, IVC min, and IVC-Collapsibility Index were found to have better results in identifying CVP>10. In detecting CVP 6, the IVC min also produced better outcomes. Therefore, all three parameters may have a significant impact for states with high CVP. IVC min can have a big impact in low CVP states. Due to the non-invasive nature of the technique, no complications were noted in the study. Conclusion: From this study, we draw the conclusion that sonographic assessment of intravascular volume status in critically ill patients aids in the early detection of hemodynamic state and helps in directing early fluid resuscitation of the patient. IVC ultrasound can be used safely in a variety of clinical situations for better management of critical care patients and avoiding the risks connected with invasive procedures because it has a good approximation in predicting actual Central Venous Pressure, which estimates intravascular volume status.
