The Association Between Perioperative Hemoglobin and Acute Kidney Injury in Patients Having Noncardiac Surgery

Abstract

Low preoperative and early postoperative decrements in hemoglobin concentrations are strongly associated with postoperative AKI in a graded manner. Given the frequency of low perioperative hemoglobin and decreases in hemoglobin concentration, research is needed to determine whether there are safe treatment strategies to mitigate the risk of AKI.
