The aim of this study is to evaluate correlation between the collapsibility indices of the FV or IJV to IVC-CI among polytrauma patients presenting to the ED by sonographic evaluation before and after resuscitation.
Polytrauma patients often present with hemodynamic instability where rapid and accurate assessment of intravascular volume is crucial. Central venous pressure monitoring, though considered a standard, is invasive and not always feasible in emergency settings. Point-of-care ultrasound (POCUS) provides a non-invasive alternative through assessment of venous collapsibility indices.
The inferior vena cava (IVC) collapsibility index is commonly used, but its evaluation may be limited in cases of abdominal trauma, obesity, or technical difficulties. The internal jugular vein (IJV) and femoral vein (FV) are superficial, easily accessible, and may provide reliable alternatives.
This study aims to compare the collapsibility indices of the IVC, IJV, and FV in polytrauma patients before and after resuscitation using sonographic evaluation. The objective is to determine their relative accuracy and feasibility as non-invasive markers of intravascular volume status to guide resuscitation in emergency settings.

The study population will include adult patients aged 18-65 years presenting with shock to the emergency department and requiring volume status assessment through both IVC,FV and IJV collabsibility indecis by ultrasound.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Ultrasound-Guided Inferior Vena Cava,femoral vein and internal jugular vein collabsibilty indecis Assessment This 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.
correlation between the collapsibility indices of the FV or IJV to IVC-CI among polytrauma patients presenting to the ED before and after resuscitation.
Time frame: correlation between the collapsibility indices of the FV or IJV to IVC-CI among polytrauma patients at time of presentation to the ED and after one hour of resuscitation.
