{Abstract}: <B>BACKGROUND: </B>Phosphorus is a vital mineral crucial for various physiological functions. Critically ill trauma patients frequently experience hypophosphatemia during the immediate post-traumatic phase, potentially impacting outcomes. This study aims to investigate the incidence of early hypophosphatemia in critically major trauma patients.<BR><B>METHODS: </B>In this prospective observational study, trauma patients admitted to the intensive care unit (ICU) within one day were enrolled. These patients were categorized into Hypo-P groups and Non-hypo groups based on the development of new-onset hypophosphatemia within 72 h after feeding. The primary outcome assessed was the incidence of new-onset hypophosphatemia. The secondary outcomes included ICU and hospital stay, ventilation duration, and mortality.<BR><B>RESULTS: </B>76.1% of patients developed a new onset of hypophosphatemia within 72 h after feeding. The Hypo-P group had significantly longer ICU stays (8.1 days ± 5.5 vs. 4.4 days ± 3.1; p = 0.0251) and trends towards extended hospital stay, ventilation duration, and higher mortality. Additionally, they demonstrated significantly higher urine fractional excretion of phosphate (FEPO4) on the first ICU day (29.2% ± 14.23 vs. 19.5% ± 8.39; p = 0.0242).<BR><B>CONCLUSIONS: </B>Critically ill trauma patients exhibited a significantly higher incidence of early hypophosphatemia than typical ICU rates, indicating their heightened vulnerability. The significantly high urine FEPO4 underscores the crucial role of renal loss in disrupting phosphate metabolism in this early acute phase after trauma. A significant correlation was observed between hypophosphatemia and longer ICU stays. Monitoring and managing phosphate levels may influence outcomes, warranting further investigation.
