Preoperative Hemoglobin and Acute Kidney Injury in Emergency Surgery

Optimization of hemoglobin levels for organ perfusion is essential, especially in critically ill patients. Although anemia is associated with severe organ failure, especially in coronary artery disease, the effects of blood transfusion or various interventions to increase hemoglobin levels on outcomes continue to be debated. The effects of hemoglobin levels in emergency surgery patients on the development of postoperative AKI have been investigated in a small number of studies in the literature, and clear results have not yet been reported. This study was designed to evaluate the effect of hemoglobin levels on the development of AKI after adjustment for known predictive factors.
