Importance of intraoperative oliguria during major abdominal surgery: findings of the Restrictive versus Liberal Fluid Therapy in Major Abdominal Surgery trial

摘要

Background: The association between intraoperative oliguria during major abdominal surgery and the subsequent development of postoperative acute kidney injury (AKI) remains poorly defined. We hypothesised that, in such patients, intraoperative oliguria would be an independent predictor of subsequent AKI.
