Gameiro J, et al. - As major abdominal surgery has the second higher incidences of acute kidney injury (AKI), after cardiac surgery and the neutrophil, lymphocytes and platelets (N/LP) ratio is an independent predictor for AKI and mortality after cardiovascular surgery, researchers evaluated the post-operative N/LP ratio after major abdominal surgery for its prognostic value. Data of a retrospective analysis of 450 patients who underwent elective or urgent major nonvascular abdominal surgery at the Department of Surgery II of Centro Hospitalar Lisboa Norte from January 2010 to February 2011 were cross-examined for this work. Outcomes revealed an independent association of postoperative N/LP ratio with AKI after major abdominal surgery, however, the ratio had no association with in-hospital mortality.
