The Relation Between Common Carotid Artery Diameter and Central Venous Pressure for Assessment of Intravascular Fluid Status After Major Surgeries: An Observational Study

Overview

Recently, bedside ultrasound has become an important tool for the simple and non-invasive hemodynamic assessment of critically ill patients. This applies not only to echocardiography but also to ultrasound of large extra-thoracic veins. The sonography can provide real time assessment of the vascular system and hemodynamic status at the bedside. To our knowledge, there is one report about the association between sonographically assessed carotid artery diameter and intravascular volume, which raised recommendation for further studies including the interplay between carotid geometry and intravascular fluid status. Aim of the study: The aim of this work is to evaluate the accuracy of noninvasive techniques for assessment of intravascular volume status by Sonographic assessment of both the common carotid artery diameter (CCA) and the central venous pressure (CVP) in response to a bolus of crystalloid solution infusion and to find the correlation between CCA diameter and CVP as the primary outcome in adults patients after major surgeries who needs close assessment and maintenance of the intravascular volume status.
