Brief summary

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.

Interventions

DEVICEUltrasound assesment of FV,IJV and IVC collabsibillity indecis

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.
