Intraoperative blood transfusion volume is an independent risk factor for postoperative acute kidney injury in type A acute aortic dissection

Table 3 Multivariable logistic regression analysis to estimate the independent association between blood transfusion volume and the risk of postoperative AKI

Variable	Model 1	P value	Model 2	P value	Model 3	P value
Blood transfusion volume ≤ 4000 ml
Increase per 200 ml	1.29 (1.08, 1.53)	0.004	1.30 (1.07, 1.57)	0.008	1.31 (1.01, 1.71)	0.044
Blood transfusion volume > 4000 ml
Increase per 200 ml	1.02 (0.96, 1.07)	0.57	1.01 (0.96, 1.07)	0.70	1.02 (0.96, 1.08)	0.61

Model 1: Crude model
Model 2: Adjusted for age, gender, hypertension, and diabetes mellitus
Model 3: Additional adjust for eGFR, emergency operation, CPB time, aortic cross clamp time, nasopharyngeal temperature, total arch replacement, semi-arch replacement, stented elephant trunk, Bentall procedure, ascending aorta replacement, intraoperative erythrocytes use, intraoperative platelets use and redo surgery
