|---|---|---|---|---|---|---|---|---|
| Baseline | CDE | % change | P value | Baseline | CDE | % change | P value | |
| rSO2 (%) | 73 (59, 76.5) | 52 (43.8, 58.5) | −26.4 (−29.2, −22.9) | < 0.001 | 77 (70, 80.8) | 54 (50.8, 57.3) | −28.8 (−33.1, −22.5) | < 0.001 |
| Mean NIBP (mmHg) | 95.5 (90, 101) | 71.5 (62.8, 83) | −23.3 (−31.6, −17.8) | < 0.001 | 95 (90.5, 99.5) | 85* (65, 100) | −14.8 (−24.6, −4.2) | 0.035 |
| Mean eABP (mmHg) | 95 (88, 109) | 66.5 (59.8, 78) | −28.4 (−37.1, −27.9) | < 0.001 | 100 (86.5, 100) | 72 (65, 92) | −11.8 (−33.9, −6.5) | 0.003 |
Data are presented as median (interquartile range). rSO2: regional cerebral tissue oxygen saturation, NIBP: non-invasive blood pressure, eABP: invasive arterial blood pressure zeroed at the external auditory meatus, CDE: cerebral desaturation event.
