Associations between AKI and time under blood pressure threshold.
| Model | Time under SBP < 100 mmHg | Time under DBP < 60 mmHg | ||
|---|---|---|---|---|
| OR | p | OR | p | |
| Model 1 | 0.86 (0.56–1.32) | 0.500 | 1.42 (0.93–2.18) | 0.105 |
| Model 2 | 0.90 (0.58–1.38) | 0.625 | 1.31 (0.84–2.02) | 0.232 |
| Model 3 | 0.81 (0.51–1.27) | 0.360 | 1.28 (0.81–2.01) | 0.293 |
Note: Logistic regression models were used to calculate the ORs. Model 1 with no adjustment. Model 2 was adjusted for age and gender. Model 3 was adjusted for age, gender, hypertension, diabetes, CHD, contrast agent, NSAIDs, diuretics, albumin, anemia, operation duration, intraoperative red blood cell transfusion, intraoperative urine output, and intraoperative colloid transfusion.
Abbreviations: AKI, acute kidney injury; CHD, coronary heart disease; DBP, diastolic blood pressure; NSAIDs, nonsteroidal anti-inflammatory drugs; OR, odds ratio; SBP, systolic blood pressure.
