Effects of cardiopulmonary bypass perfusion temperature on perioperative renal function in adult patients undergoing cardiac surgery

Renal Outcome in Patients Undergoing Cardiac Surgery Using Cardiopulmonary Bypass

“…We suspect that the low sample size was the main reason that we got an insignificant association between postoperative renal dysfunction and CPB time. Our study has shown a significant association with preoperative renal function and postoperative renal dysfunction, and this is similar to many studies that show that preoperative renal dysfunction, as measured by serum creatinine levels, increases the risk of developing acute kidney injury [17][18].…”

“…There were more males compared to females, similar to the results from different articles that have been conducted with a male-to-female ratio of almost 3:1 [16][17][18][19]. Demographic data and cardiac co-morbidities, such as hypertension, diabetes, and dyslipidemia, did not show any statistically significant association with postoperative renal dysfunction.…”

“…Also, none of the participants required permanent dialysis, and only 8% of our population showed postoperative renal dysfunction. In contrast to the other articles that showed a higher incidence of mortality, dialysis, and renal dysfunction [16][17][18].…”

Predictive value of neutrophil to lymphocyte ratio on acute kidney injury after on-pump coronary artery bypass: a retrospective, single-center study

“…Previous studies showed that prolonged cardiopulmonary bypass time and ACC time were also independent risk factors for postoperative complications of AKI in patients undergoing ONCAB [22,23]. Since renal blood flow and perfusion are relatively insufficient during extracorporeal circulation, massive erythrocytes were destroyed, and the released free hemoglobin consequently caused tubular obstruction and reduced glomerular rate filtration.…”
