title: Acute kidney injury after cardiac surgery in eastern Saudi Arabia.
abstract: Acute kidney injury is a serious complication after cardiac surgery. This study was conducted to determine the frequency of acute kidney injury and the associated risk factors following cardiac surgery at Dhahran health centre in eastern Saudi Arabia. All patients who underwent cardiac surgery between June 2005 and December 2008 were included. Of 293 patients who fulfilled the criteria and were included in the final analysis, 85 (29.0%) developed acute kidney injury. Using multivariate analysis, the factors significantly associated with acute kidney injury were age, diabetes, preoperative chronic kidney disease and emergent surgery. Mortality associated with acute kidney injury was 10.5% overall and 42.9% when dialysis was required. Acute kidney injury following cardiac surgery is a serious problem among patients in eastern Saudi Arabia. Measures to prevent this complication are essential.
