简要总结
Accurate assessment of intravascular volume status in critically-ill patients is crucial for their diagnosis and management. Traditional CVP measurement requires invasive central venous catheter placement which is time consuming and is associated with potential complications. Clinician performed bedside ultrasonographic evaluation of the IVC is a potential tool that could provide an instant and non-invasive measure of volume status. This cross sectional study aims to establish the accuracy of ultrasonography as a feasible, rapid and non-invasive method for assessment of intravascular volume status in spontaneously breathing critically ill patients.

排除标准
- •Patients in whom CVC is contraindicated, patients with overt right heart failure or with moderate to severe tricuspid regurgitation, patients with clinical signs of elevated intra abdominal pressure, Patients for whom required ultrasound examination would not be appropriate , mechanically ventilated patients, patients who refused to participate in the study.
结局指标
主要结局
To assess the correlation between inferior vena cava diameters, central venous pressure and IVC collapsibility index for estimating the volume status in critically ill patients
时间窗: Ultrasound image acquisition recording will be done initially. After one minute central venous pressure will be measured
次要结局
- To establish inferior vena cava diameter & IVC collapsibility index as a non invasive tool for the evaluation of intravascular fluid volume & to guide fluid management in critically ill patients(Baseline USG guided IVC diameter & IVC collapsibility index obtained. After 1 minute CVP will be measured & values will be correlated)
