Urinary Output During The Aortic Cross-Clamping Period In Isolated Coronary Artery Bypass Grafting Surgery: An Indicator of Postoperative Acute Kidney Injury.

Methods: This prospective study was performed on patients who underwent isolated coronary artery bypass surgery between January 2016 and April 2017. Patients with an increase of more than 1.5 times in their preoperative creatinine values on their third postoperative day were considered to have acute kidney injury according to RIFLE criteria. The patients were divided into two groups as AKI (+) and AKI (-), regarding presence of AKI. Results: Acute kidney damage developed in 12 patients out of 146 patients studied. Demographic data, and intraoperative variables were similar between the groups (p>0.05). The urinary output during ACC (mL/kg/h) of the AKI (-) group was significantly higher than that of the AKI (+) group (p=0.045).
