Neutrophil, Lymphocyte, and Platelet Counts and Acute Kidney Injury After Cardiovascular Surgery

摘要

Objective: Postoperative low platelet count and perioperative high neutrophil/lymphocyte (N/L) ratio are associated with acute kidney injury (AKI) and mortality after cardiac surgery. The authors investigated whether (1) their combination neutrophil/lymphocyte x platelet (N/LP) ratio is an independent predictor of AKI and postoperative mortality and (2) whether the N/LP ratio increases predictive ability compared with the N/L ratio or platelet nadir.
