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.
