Decreases in cerebral saturation in patients with septic shock are associated with increased risk of death: a prospective observational single center study

There was no difference in SctO₂ between groups with respect to the presence of acute kidney injury (AKI) nor being Confusion Assessment Method (CAM-ICU) positive. Patients who died had decreases in SctO₂ of greater magnitude than those that survived. Data are presented as median [interquartile range]. Values are represented as median [interquartile range]
% Time percentage of time spent below an SctO₂ of 65 %
AUT area under threshold (% min⁻¹ hr⁻¹)
