Femoral Vein, Internal Jugular Vein and Inferior Vein Cava Collapsibility Indices in Polytrauma Patients by Sonographic Evaluation Before and After Resuscitation.

December 2, 2025 updated by: Mahmoud Ahmed Abdelrady Mahmoud, Assiut University

Comparative Study of Femoral Vein, Internal Jugular Vein and Inferior Vein Cava Collapsibility Indices in Polytrauma Patients Presenting to the Emergency Department by Sonographic Evaluation Before and After Resuscitation.

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.

Detailed Description

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.
