RESUMEN
INTRODUCTION: Prevention of acute kidney injury during cardiopulmonary bypass (CPB) is still a challenge and has been the object of numerous studies. The incidence of acute kidney injury in the context of CPB is related to a multifactorial etiology. The role of hemadsorption in relation to cell-free hemoglobin and haptoglobin preservation is not well defined in the literature on CPB during cardiac surgery procedures. METHODS: This is a single-center pilot randomized report including 20 patients undergoing elective CPB procedures with an expected time > 120 minutes for each extracorporeal procedure. Patients were randomly allocated to either standard of care (n=10) or Jafron HA380 (n=10) during CPB. The primary outcome measured was the incidence of postoperative acute kidney injuries. RESULTS: The Jafron study group vs. control group reported postoperative values for cell-free hemoglobin at 10 minutes after CPB (mg/L) (11.6 ± 0.6 vs. 29.9 ± 0.3) (P-value 0.021), haptoglobin 10 minutes after CPB (mg/dl) (129.16 ± 1.22 vs. 59.17 ± 1.49) (P-value 0.017), creatinine peak after CPB (mg/dL) (0.92 ± 0.17 vs. 1.32 ± 0.9) (P-value 0.030), and acute kidney injury after 48 hours (number of patients) (one vs. four) (P-value 0.027). CONCLUSION: This pilot study suggested that the use of Hemoperfusion Cartridge HA380 Jafron for extended CPB time for complex cardiac surgery procedures was safe and effective and is associated with a better postoperative preservation of haptoglobin with a reduction of cell-free hemoglobin values and less incidence of acute kidney injury, though larger studies are warranted to confirm our result.

Cardiac surgery with cardiopulmonary bypass (CBP) is essential for different cardiac procedures in order to perform surgery with a clear sight field.To safely perform surgery with CPB and preserve brain, kidney, and patient tissue from ischemic damage, cold cardioplegia, and mild to deep hypothermia are induced during the operation.Cryoglobulinemia is a hematological/infective-related disease (in certain cases idiopathic) in which temperature-dependent antibodies tend to aggregate and form emboli in the vascular system causing tissue damage if exposed to low temperature.The patient with cryoglobulinemia (known and unknown) can be at risk of a major ischemic event during CPB and induced hypothermia.This article's aim is to evaluate the present scientific literature in order to understand how, in years, the therapeutic or preventive approach, is evolving, and to analyze and make improvements to the management of a cryoglobulinemic patient who must undergo elective or emergency cardiac surgery.In the last part of our article, we expose our single-center experience during a 32-month-long period of survey.In all cases, our medical team (anesthesiologists, perfusionists, and cardiac surgeons) opted for a normothermic cardiopulmonary bypass to lower the risk of cryoglobulin-associated complications.In our experience, along with therapeutic intervention to lower the cryoglobulin titer, normothermic management of cardiopulmonary bypass is as safe as hypothermic management.Notwithstanding our results, further studies with a larger population are needed to confirm this perioperative management in a cardiac surgery setting.

ABSTRACT Introduction: Prevention of acute kidney injury during cardiopulmonary bypass (CPB) is still a challenge and has been the object of numerous studies. The incidence of acute kidney injury in the context of CPB is related to a multifactorial etiology. The role of hemadsorption in relation to cell-free hemoglobin and haptoglobin preservation is not well defined in the literature on CPB during cardiac surgery procedures.
