Acute kidney injury in burns in the intensive care unit: A retrospective research

BACKGROUND: Acute kidney injury (AKI) is one of the common complications, associated with high mortality and morbidity in patients with burn injuries. This study aimed to determine the frequency of AKI development, its affective factors, and mortality rates according to kidney disease improving global outcomes (KDIGO) criteria in the burn patients.METHODS: The study included patients who are hospitalized for at least 48 h and aged >18 years, whereas patients with a renal transplant, chronic renal failure, undergoing hemodialysis, <18 years of age, with a glomerular filtration rate of <15 on admission, and toxic epidermal necrolysis was excluded from the study. KDIGO criteria were used to evaluate the occurrence of AKI. Burn mechanism, total body surface area, inhalation injury respiratory tract burn, fluid replacement at 72 h with Parkland Formula, mechanical ventilator support, inotrope/vasopressor support, intensive care unit, lenght of stay, mortality, abbreviated burn severity index (ABSI), acute physiology, and chronic health evaluation II (APACHE II) ve Sequential organ failure assessment (SOFA) were recorded.RESULTS: A total of 48 patients were included in our study, of which 26 (54.2%) developed AKI (+), whereas 22 (45.8%) did not (-). The mean total burn surface area was 47.30% in the AKI (+) group and 19.88% in the AKI (-) group. Mean scores of ABSI, II (APACHE II), and SOFA, the mechanical ventilation and inotrope/vasopressor support and the presence of sepsis were significantly higher in the AKI (+). No mortality was determined in the AKI (-) group, whereas 34.6% in the AKI (+) group which was significantly high.CONCLUSION: AKI was related to high morbidity and mortality in patients with burns. Using KDIGOs, classification in daily follow-up is useful in early diagnosis.
