Multivariable analysis of AUT of absolute SrrO2 (baseline-3 SD) and AKI
| Variables | OR (95% CI) | P-value |
|---|---|---|
| SrrO2 AUT (per min%, baseline -3SD)a | 4.629 (1.238, 17.314) | 0.023 |
| Euroscore II (< 1.18 versus ≥ 1.18) | 0.702 (0.276, 1.788) | 0.458 |
| Intraoperative inotropic score (< 5 versus ≥ 5) | 2.228 (0.504, 9.860) | 0.291 |
| Length of CPB (< 140 min versus ≥ 140 min) | 0.423 (0.168, 1.066) | 0.068 |
| Lowest MAP during CPB (per 5 mmHg increase) | 0.935 (0.625, 1.398) | 0.742 |
| Torsemide during CPB (yes versus no) | 0.189 (0.021, 1.724) | 0.140 |
Abbreviations: CI confidence interval, OR odds ratio, SrrO2 renal region tissue oxygen saturation
The confounders included in this multivariable logistic regression are Euroscore II, intraoperative inotropic score, length of CPB, lowest MAP during CPB, and Torsemide during CPB
aWhen using the absolute SrrO2 desaturation (baseline-2.5 SD) in multivariable logistic regression, the OR is 2.84 (95% CI, 1.03, 7.88; P = 0.045)
