1 Reduced cerebral oxygen saturation measured by absolute cerebral oximetry during thoracic surgery correlates with postoperative complications  R. Kazan, D. Bracco, T.M. Hemmerling  British Journal of Anaesthesia  Volume 103, Issue 6, Pages (December 2009) DOI: /bja/aep309 Copyright © 2009 British Journal of Anaesthesia Terms and Conditions

2 Fig 1 SctO2 mean absolute values (median, first quartile, third quartile) during surgery, at five different time points for 50 patients; t-test was performed to compare values of different time points. The awake value is considered as the baseline value. After intubation, recorded immediately after intubation at Fio2=1.

3 Fig 2 (a) Cerebral desaturation: degree of maximal SctO2 decrease for all patients (n=50) in per cent relative to the baseline value (<15%, 15–19%, 20–25%, >25%). (b) Minimal absolute SctO2 values reached by patients (n=50) during SLV. British Journal of Anaesthesia  , DOI: ( /bja/aep309) Copyright © 2009 British Journal of Anaesthesia Terms and Conditions

4 Fig 3 Linear relation between the SctO2 minimum absolute value and (a) the SOFA (non-respiratory) score and (b) the Clavien score. British Journal of Anaesthesia  , DOI: ( /bja/aep309) Copyright © 2009 British Journal of Anaesthesia Terms and Conditions
