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 systolic heart failure (HF). METHODS: We included 136 consecutive patients with systolic HF (left ventricular ejection fraction, <50%), including 80 patients with acutely decompensated HF and 56 patients with compensated HF as well as 50 subjects without a diagnosis of HF...

OBJECTIVES: Our primary objective was to determine the prevalence and outcome of diastolic dysfunction in children with fluid refractory septic shock. The secondary objective was to determine possible early predictors of diastolic dysfunction. DESIGN: Prospective observational study. SETTING: PICU of a tertiary care teaching hospital. PATIENTS: Consecutive children 17 years old or younger with fluid refractory septic shock and not on mechanical ventilation admitted to our ICU from June 2011 to August 2012 were included...

PURPOSE: Assessment of volume status remains a challenge in critical care. Our purpose was to determine if Doppler waveform analysis of carotid artery blood flow correlates with changes in volume status. MATERIALS AND METHODS: Dehydrated patients receiving an intravenous fluid bolus were enrolled with exclusions including age less than 18 years, pregnancy, vasopressor administration, or atrial fibrillation. Ultrasound examination with Doppler analysis of the carotid artery was performed with measurements taken to calculate corrected flow time (FTc)...

OBJECTIVES: Previous studies demonstrated that the collapsibility index (percent decrease in inferior vena cava [IVC] diameter with inspiration) of 50% or greater and an IVC/aorta ratio of 0.8 or less correlated with a low intravascular volume. Our study sought to determine if bedside ultrasound (BUS) measurements of the IVC diameter correlate with central venous pressure (CVP) measurements as an indicator of intravascular volume status in acutely ill children. METHODS: A convenience sample of children younger than 21 years who were admitted to the pediatric critical care unit and required CVP monitoring had BUS measurements of both IVC and aortic diameters with simultaneous CVP measurement...

OBJECTIVES: Prospectively identifying children with significant dehydration from gastroenteritis is difficult in acute care settings. Previous work by our group has shown that bedside ultrasound (US) measurement of the inferior vena cava (IVC) and the aorta (Ao) diameter ratio is correlated with intravascular volume. This study was designed to validate the use of this method in the prospective identification of children with dehydration by investigating whether the IVC/Ao ratio correlated with dehydration in children with acute gastroenteritis...

OBJECTIVES: Bedside ultrasonography (US) measurement of the inferior vena cava (IVC) and aorta (Ao) may be useful in objectively assessing children with dehydration. The objectives of this study were 1) to compare the IVC and Ao diameters (IVC/Ao) ratio of dehydrated children with controls and 2) to compare the IVC/Ao ratio before and after intravenous (i.v.) rehydration in children with dehydration. METHODS: This prospective observational study was performed in an urban pediatric emergency department...
