Incidence and Outcomes of Acute Kidney Injury in Trauma Patients Admitted to Critical Care

Trauma can cause high mortality and morbidity by affecting different organ systems. Acute kidney injury (AKI) is a common complication in trauma patients admitted to the intensive care unit (ICU). Direct kidney injury, hypotension, hypoperfusion, rhabdomyolysis, abdominal compartment syndrome, sepsis and critical care medications are possible causes of AKI in trauma patients. The incidence of AKI can be up to 10%, and mortality rate up to 60-80% in trauma patients. Since AKI is not only a rare complication but also a risk factor for mortality in critically ill trauma patients, it is essential to establish a strategy to prevent AKI and related complications, to determine the incidence and risk factors of AKI, and to improve patients outcomes. Survivors of AKI may have variable recovery of kidney function and might prone to late morbidity and mortality. In this study incidence of AKI was defined using the KDIGO criteria according to the change of serum creatine levels.

171 all type of trauma patients admitted to level 3 ICU, from January 2014 to December 2018 included the retrospectve observational study. Demographic data, type of injury, rates of complications, risk factors for AKI, mortality, lenght of stay (LOS) in ICU were evaluated. Acute Physiology and Chronic Health Evaluation (APACHE II and IV) score, Simplified Acute Physiology Score (SAPS II and III), Glasgow Coma Scale (GCS), Injury Severity Score (ISS) and, Trauma Injury Severity Score (TRISS) were calculated on the day of admission. AKI was defined using the KDIGO criteria according to the serum creatinine. The SPSS 11.5 program was used for statistical analysis.
