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

Table 4 Comparison of cerebral saturation between septic and surgical patients

Parameter	Septic	Surgical	p value
Number of patients with desaturations	12/15	9/30	< 0.01
Percent time below SctO₂ threshold	2.2 [0.9–10.9]	0 [0.0–8.8]	0.03
AUT/h	3.1 [0.3–14.5]	0.0 [0.0–6.9]	0.04

Septic patients had decreases in their SctO₂ more frequently and of a greater magnitude than surgical patients. Data are presented as median [interquartile range]. The number of patients with desaturations was compared using Fisher’s exact test, while percent time and AUT/Hr differences were compared with Mann-Whitney U test
Percent time percentage of time spent below an SctO₂ of 65 %
AUT area under threshold (% min⁻¹ hr⁻¹)
