Ultrasound Measurement of Inferior Vena Cava Diameter Versus Central Venous Pressure As a Tool of Assessment of Intravascular Volume in Adult ICU Patients

Abstract

luid resuscitation in critically ill patients is a common and serious challenge, so careful management is an important determinant of outcomes of critically ill patients.Overtreatment causes many different complications such as pulmonary edema, abdominal hypertension, and compartment syndrome leads to progressive organ dysfunction and death. Measurements of central venous pressure (CVP), pulmonary arterial catheterization, esophageal Doppler, ultrasound, and trans-esophageal echocardiography may be used to determine the volume status of critically ill patients. Appropriate interpretation of the information offered by hemodynamic monitoring requires the integration of several variables. Echocardiography is increasingly used as a first tool to identify a problem and help select initial treatment. To improve patient management and outcome, the clinician must understand the advantages and the limitations of the various tools and parameters used during ICU stay. CVP refers to the pressure of the right atrium or superior vena cava and helps inform emergency departments and critical care units about what fluid and diuretic treatment to apply.However, hemodynamic monitoring with central venous ultrasound catheterization is limited in being costly and invasive. Considering complications such as infections,
