INTRODUCTION Rapid diagnosis of volume overload in patients with suspected congestive heart failure (CHF) is necessary for the timely administration of therapeutic agents. We sought to use the measurement of respiratory variation of inferior vena cava (IVC) diameter as a diagnostic tool for identification of CHF in patients presenting with acute dyspnea. METHODS The IVC was measured sonograph...

PURPOSE The purpose of this study was to assess the accuracy of carbon dioxide compared to iodinated contrast material for determining inferior vena cava (IVC) diameter prior to filter placement, and to assess the safety of CO2 when used for this purpose. PATIENTS AND METHODS Consecutive patients undergoing inferior vena cavography prior to filter placement were prospectively evaluated with u...

INTRODUCTION The early detection of critically ill patients together with the rapid initiation of effective treatment in emergency departments(ED) increase the survival rates. AIM This study investigated whether a correlation exists between haemodynamic parameters of critically ill patients and the diameter of the inferior vena cava (IVC). MATERIALS AND METHODS A cross-sectional study was p...

OBJECTIVE We aimed to present inferior vena cava (IVC) diameter as a guiding method for detection of relationship between IVC diameter measured noninvasively with the help of ultrasonography (USG) and central venous pressure (CVP) and evaluation of patient's intravascular volume status. METHODS Patients over the age of 18, to whom a central venous catheter was inserted to their subclavian vei...

BACKGROUND Some surgeons may lack proper experience in abdominal packing. Overpacking may directly compress the inferior vena cava (IVC). This reduces the venous return and possibly causes hypotension. Here, a new on table Point-of-Care Ultrasound application that has been recently used to assess the effect of abdominal packing on the IVC diameter is described. Following abdominal packing, a sm...

BACKGROUND We determined the value of the inferior vena cava (IVC) diameter for predicting acute blood loss in control and blunt trauma patients and compared this with other parameters of hemorrhagic shock. METHODS Fifty volunteers and 28 consecutive hemorrhagic shock patients were recruited prospectively to participate in the study. Vital signs, blood lactate, and serum bicarbonate were meas...

INTRODUCTION Both inferior vena cava (IVC) diameter and the degree of inspiratory collapse are used in the estimation of right atrial pressure. AIM The purpose of this study is to evaluate the utility of IVC diameter, using echocardiography as a marker of volume overload and the relationship between these parameters and N-terminal pro-B natriuretic peptide (NT-proBNP) in patients with systoli...

AIMS Although the inspiratory 'collapse' of the inferior vena cava (IVC) has been used to signify normal central venous pressure, the effect of the manner of breathing IVC size is incompletely understood. As intra-abdominal pressure rises during descent of the diaphragm, we hypothesized that inspiration through diaphragmatic excursion may have a compressive effect on the IVC. METHODS AND RESU...

Objective: Fluid resuscitation is necessary in almost all critical patients. The central venous pressure (CVP) is a well-established method of assessing resuscitation. Recently, there have been attempts to investigate less invasive methods like the diameters of inferior vena cava (IVC) or the jugular vein. We aimed to investigate this method in our research.Methods: Seventy eight critical...
