Table 6

Independent predictors of delirium in a multivariate analysis-subanalysis in patients who underwent CABG and/or valve procedure.

Variable	Logistic OR	95% CI	“P”
Obstructive pulmonary disease (yes = 1)	4.809	1.264–18.296	0.02
Any blood transfusion (yes = 1)	3.904	2.054–7.420	<0.001
Postoperative cerebral ischemia (yes = 1)	2.743	1.211–6.210	0.01
Carotid artery stenosis (yes = 1)	2.491	1.272–4.878	0.008
Age > 65 years (yes = 1)	2.307	1.162–4.580	0.01
ΔpO2 (<ΔQ1 or >ΔQ3 versus ΔQ1−3)	1.011	1.008–1.015	<0.001
Liver disease in anamnesis (yes = 1)	0.104	0.011–0.964	0.046

OR: odds ratio, CI: confidence interval, pO₂: arterial oxygen partial pressure, Δ: intraoperative fluctuation (max − min).
