Abstract

Introduction: Hypovolemia is the commonest cause of shock and death in traumatic patients, resulting in multiple organ failures due to inadequate circulating volume and subsequent inadequate oxygen perfusion to organs and tissues.
Fluid disturbance and resuscitation can be assessed and monitored by clinical observation by an invasive or non-invasive method. One of the non-invasive methods is urine osmolality, an easy and non-complicated method.
Objective: Enhance the management of traumatic hypovolemic shock in the emergency department through rapid evaluation of quantity and quality of hydration by a single physiological non-invasive method: urine osmolality.
Methods: This diagnostic cross-sectional comparative study was conducted in the emergency department and randomly 40 patients with hypovolemic shock after severe major trauma during the preceding 8 hours according to the inclusion and exclusion criteria. Assessment is done according to the primary survey for multiple trauma patients (ABCDE) approaches.
Results: The urine osmolality was significantly decreased during follow-up, from 1009±103.2 mOsm/kg H2O at admission to 759.8±69.1 mOsm/kg H2O at 8 hours (p
