The role of internal jugular vein Doppler ultrasonography in predicting hypovolemic shock in polytrauma patients

다국어 초록 (Multilingual Abstract)

Purpose: The aim of this study was to evaluate the accuracy of internal jugular vein (IJV) Doppler ultrasonography in predicting hypovolemic shock in polytrauma patients.Methods: This prospective observational study was conducted on 75 multiple trauma patients (injury severity score >15) with a mean age of 33.00±9.57 years. IJV Doppler ultrasonography was performed in all patients with stable vital signs and a negative extended focused assessment with sonography for trauma. Jugular pulsatility index (JPI) values were calculated using the equation (V_max-V_min)/V_max. Clinical and laboratory indices of hypovolemic shock were recorded at the time of admission. Patients were subsequently divided into those with hemorrhagic shock (n=36) and those without (n=39) based on the occurrence of hemorrhagic shock within 6 hours after admission. The results were compared between these groups.Results: IJV Doppler ultrasound parameters (JPI, V_min, and V_max-V_min) showed significant differences between the two groups. The JPI values of patients with hemorrhagic shock were significantly lower than those in the control group (0.43±0.21 vs. 0.78±0.24, P<0.001). The sensitivity, specificity, and discriminant ability (area under the curve) of JPI with a cutoff of 0.58 in detecting hemorrhagic shock were 86.11%, 82.05%, and 0.853 (P<0.001), respectively.Conclusion: IJV Doppler ultrasonography can reliably predict hemorrhagic shock in polytrauma patients with stable vital signs. Ultrasonography can be used in combination with clinical signs and laboratory findings to diagnose patients at risk of hypovolemic shock.
