摘要：Background. We analyzed the incidence, risk factors, and prognosis of acute kidney injury (AKI) in a cohort of patients undergoing major abdominal surgery. Methods. A total of 450 patients were retrospectively studied. AKI was defined by an increase in serum creatinine (SCr) ≥ 0.3 mg/dl or by an increase in SCr ≥ 50% and/or by a decrease in urine output to 0.5 ml/kg/hour for 6 hours, in the first 48 hours after surgery. Logistic regression method was used to determine predictors of AKI and in-hospital mortality. A two-tailed value <0.05 was considered significant. Results. One hundred one patients (22.4%) had postoperative AKI. Age (adjusted odds ratio (OR) 1.02, 95% confidence interval (CI) 1.01–1.05), nonrenal Revised Cardiac Risk Index score (adjusted OR 1.9, 95% CI 1.3–3.1, ), intraoperative erythrocytes transfusions (adjusted OR 2.2, 95% CI 1.4–3.5, ), and nonrenal Simplified Acute Physiology Score II (adjusted OR 1.03, 95% CI 1.01–1.06, ) were associated with postoperative AKI. AKI was associated with increased in-hospital mortality (20.8% versus 2.3%, ; unadjusted OR 11.2, 95% CI 4.8–26.2, ; adjusted OR 3.7, 95% CI 1.2–11.7, ). Conclusion. AKI was common in patients undergoing major abdominal surgery and was associated with in-hospital mortality.
