ALB and acute kidney injury: We identified that age (adjusted OR, aOR = 1.112; 95% CI, 1.020–1.212), serum albumin (aOR = 0.900; 95% CI, 0.829–0.977), eGFR < 60 (aOR = 3.401; 95% CI, 1.479–7.820), IOH (aOR = 3.509; 95% CI, 1.553–7.929) and combined therapy of HES with NSAIDs (aOR = 3.596; 95% CI, 1.559–8.292) or HES with furosemide (aOR = 5.724; 95% CI, 1.476–22.199) were independent predictors of the development of postoperative AKI (Table 2).
