About this trial
This study aims to compare ultrasound-guided inferior vena cava (IVC) assessment with central venous pressure (CVP) monitoring for the detection of hypovolemia in shock patients in the emergency department. The primary objective is to evaluate the diagnostic accuracy and clinical utility of IVC collapsibility index compared to CVP values in both early and post-resuscitation phases. The study will prospectively enroll shock patients, collect demographic and clinical data, and analyze the correlation between IVC and CVP measurements to determine their role in guiding fluid resuscitation and hemodynamic management.

Treatments tested in this trial
Ultrasound-Guided Inferior Vena Cava Assessment
DeviceThis intervention involves bedside ultrasound measurement of the inferior vena cava (IVC) diameter and calculation of the IVC collapsibility/distensibility index. Assessments will be performed both at initial presentation and after fluid resuscitation in shock patients. The procedure is non-invasive, rapid, and performed according to standardized emergency ultrasound protocols, distinguishing it from invasive monitoring methods.

Correlation Between IVC Collapsibility Index and Central Venous Pressure
The primary outcome is to assess the diagnostic agreement between ultrasound-guided inferior vena cava (IVC) collapsibility index and central venous pressure (CVP) values in detecting hypovolemia among shock patients in the emergency department. Measurements will be collected at two time points: during early presentation and after initial fluid resuscitation. The outcome will be evaluated by analyzing correlation coefficients, sensitivity, and specificity of IVC measurements compared with CVP
Time frame
IVC assessment will be performed at presentation and 1 hour post-resuscitation, while CVP will be monitored continuously during the first 6 hours after ED admission.Sponsors and contacts
