Introduction: Patients at risk for acute renal failure include the elderly, those with diabetes mellitus, heart failure, liver failure, chronic kidney disease, hypotension, and bloodstream infections. The aim of this study was to investigate the underlying factors of acute lung failure in trauma patients admitted to the ICU of Imam Khomeini Hospital in Urmia.
Material and Methods: Patients were classified into three categories: perrenal, renal and postrenal. The differentiation of these three categories was based on the diagnosis recorded in the file and the summary of the patient''s case. Incomplete records and patients with a history of dialysis, ESRD, and GN patients who do not meet the criteria for acute renal failure were excluded.
Results: Out of 10 patients with acute kidney injury, there was no case of disease and out of 110 patients without acute kidney injury, 18 (16.4%) had the disease. According to Fisher Exact test, there was no significant relationship between comorbidity and acute kidney injury (P = 0.18).
Conclusion: Older patients with AKI have more severe disease and sepsis. The mortality rate in patients with AKI is higher than patients without AKI, especially in patients with oliguria. Data analysis showed that age, SAPS II, heart failure, liver cirrhosis, body fluid balance and mechanical ventilation were independently associated with 60-day mortality in these patients.
