Objective: to assess the relationship between oxygen delivery during cardiopulmonary bypass and the incidende of acute kidney injury in the immediate postoperative period of patients undergoing cardiac surgery, as well as to identify possible risk factors. Methods: A retrospective observational study of patients undergoing cardiac surgery scheduled between May 2016 and February 2018 was carried out in which the M-M4 System was used for online blood gases. Patients with preoperative diagnosis of chronic renal failure were excluded. For the oxigen delivery, the average of all M4 records was made. Results: 133 patients (35.3% women) with a mean age of 64.9 ± 10.9 years were studied. The incidence of acute kidney injury was 18.8% (AKI I: 12%; AKI II: 3%; AKI III: 3.8%). There was no correlation between acute kidney injury and O2 delivery (251 ± 43 vs 247 ± 52, ns), if there was a difference when patients needed renal replacement therapy (251 ± 43 vs 198 ± 18, p = 0.04). There was a significant increase risk in diabetes; HTA; pulmonary arterial hypertension; chronic atrial fibrilation; red blood cell concentrate and blood products administration in the operating room; redo for bleeding; high lactic acid and glycemia post cardiopulmonary bypass; prolonged pump and ischemia times; and combined surgery. Conclusions: There was no direct relationship between O2 delivery and acute kidney injury, although there was a significantly lower O2 delivery in patients who needed postoperative renal replacement therapy.

Objective: This study evaluated the relationship between the amount of urinary output during cardiopulmonary bypass and acute kidney injury in the postoperative period of coronary artery bypass grafting.Methods: Two hundred patients with normal preoperative serum creatinine levels, operated on with isolated CABG between 2012-2014 were investigated retrospectively. The RIFLE (Risk, injury, failure, loss of function, and end-stage renal disease) risk scores were calculated for each patient in the third postoperative day. Patients were distributed into two groups in relation to the presence of acute kidney injury or not and these two groups were compared.Results: The urinary output (mL/kg/hour) during cardiopulmonary bypass in the acute kidney injury negative group was significantly higher than in the acute kidney injury positive group (P = .022). In case of a urinary output value 3.70 and lower to predict acute kidney injury positivity, sensitivity was detected as 71.43%. Results of the analysis for urinary output predict positivity of acute kidney injury.Conclusion: We suggest that urine output during cardiopulmonary bypass is a significant criteria that could predict acute kidney injury following coronary artery bypass grafting with cardiopulmonary bypass. Attempts to increase the urine output during cardiopulmonary bypass could help to maintain the renal functions during and after surgery.

Urinary liver-type fatty acid binding protein (L-FABP) is a novel biomarker with promising performance in detecting kidney injury. Previous studies reported that L-FABP showed moderate discrimination in patients that underwent cardiac surgery, and other studies revealed that longer duration of cardiopulmonary bypass (CPB) was associated with a higher risk of postoperative acute kidney injury (AKI). This study aims to examine assessing CPB duration first, then examining L-FABP can improve the discriminatory ability of L-FABP in postoperative AKI. A total of 144 patients who received cardiovascular surgery were enrolled. Urinary L-FABP levels were examined at 4 to 6 and 16 to 18 h postoperatively. In the whole study population, the AUROC of urinary L-FABP in predicting postoperative AKI within 7 days was 0.720 at 16 to 18 h postoperatively. By assessing patients according to CPB duration, the urinary L-FABP at 16 to 18 h showed more favorable discriminating ability with AUROC of 0.742. Urinary L-FABP exhibited good performance in discriminating the onset of AKI within 7 days after cardiovascular surgery. Assessing postoperative risk of AKI through CPB duration first and then using urinary L-FABP examination can provide more accurate and satisfactory performance in predicting postoperative AKI.
