Abstract
BACKGROUND: Acute kidney injury (AKI) is associated with high morbidity and mortality. Recombinant human erythropoietin has been shown to exert cytoprotection against ischemia. This study examined the effect of erythropoietin in preventing AKI during thoracic aortic surgery with moderate hypothermic circulatory arrest. METHODS: In this double-blind, randomized study, 66 patients undergoing thoracic aortic surgery with moderate hypothermic circulatory arrest (target temperature, 28 degrees C) randomly received either erythropoietin 500 IU.kg(-1) or the same amount of normal saline intravenously after anesthesia induction. The primary endpoint was incidence of AKI defined according to the RIFLE criteria during the first 7 postoperative days. RESULTS: AKI occurred in 60% of all patients. The two groups did not show any differences in the incidence and severity of AKI. Also, there was no difference in the level of serum neutrophil gelatinase-associated lipocalin between the groups. The cardiac index was higher in the erythropoietin group, however, immediately after weaning from cardiopulmonary bypass (p = 0.02). Furthermore, postoperative cardiac complications and prolonged vasopressor dependence were reduced in the erythropoietin group (p = 0.04 and p = 0.049, respectively). CONCLUSIONS: A single bolus administration of erythropoietin 500 IU.kg(-1) at anesthesia induction failed to provide renoprotection in patients who underwent thoracic aortic surgery with moderate hypothermic circulatory arrest. However, erythropoietin significantly reduced cardiac complications, and lowered the incidence of prolonged vasopressor dependence.
