Results

We obtained perioperative free hemoglobin(fHb) and haptoglobin(Hp) levels during the study period in adult patients undergoing valvular and aortic surgery requiring cardiopulmonary bypass (CPB). The increase of fHb level and decrease of Hp level had independent associations with post operative AKI. And, we estimated cutoff values were 0.06g/dL at CPB1(1hr after CPB) , 0.12g/dL as preoperative maximum fHb(maxfHb), respectively.

Baseline Characteristics

We evaluated 120 patients without chronic renal failure who underwent cardiac surgery that required CPB . Among them, we excluded patients who were administered external haptoglobin in the perioperative period and patients in whom more than one CPB or reoperation was performed. We finally included 74 patients in this study.Postoperative AKI occurred in 25 (33.8%) of those patients.Patients with AKI were significantly older than patients without AKI (p=0.01) and had a lower preoperative eGFR (p=0.04) than that in patients without AKI. The median value of MAP during CPB in patients with AKI was 51.3 (43.9-63.4) mmHg, which was not significantly different from the median value of 54.5 (45.3-64.8) mmHg in patients without AKI (p=0.49). There was no significant difference in other demographics.

Participant flow

We evaluated 120 patients without chronic renal failure who underwent cardiac surgery that required CPB . Among them, we excluded patients who were administered external haptoglobin in the perioperative period and patients in whom more than one CPB or reoperation was performed. We finally included 74 patients in this study.

Adverse events

Nothing of note

Outcome measures

The primary outcome was postoperative AKI defined by Kidney Disease: Improving Global Outcomes. Postoperative AKI was determined by an increase in creatinine level of 0.3 mg/dl or more above the preoperative value or an increase in creatinine level of 50% or more within 48hours after the operation.
