Association between baseline cerebral oxygenation and postoperative outcomes in older noncardiac surgical patients: An exploratory observational study
Authors' conclusion
The utility of baseline rSO2 as a biomarker of adverse postoperative outcomes can potentially extend to noncardiac surgical patients, especially for older populations.
Study context
- Population
- Patients over 65 years scheduled for elective noncardiac surgery, 2017–2019254 analysed
- Comparison
- Baseline rSO2 by 30-day readmission and mortality
- Primary endpoint
- Morbidity and mortality rates
- Follow-up
- 30 days
Methodological detailsexploratory, Unilateral baseline rSO2 measured on admission to the surgical ward
- Exploratory
- Unilateral baseline rSO2 measured on admission to the surgical ward
Primary result
As reported in the abstract
30-day readmission and mortality; association with baseline rSO2
- Readmitted within 30 days
- 17 (7 %)
- Died within 30 days
- 5 (2 %)
- Baseline rSO2 significantly associated with readmission, mean (SD) 58 (10) vs 65 (8)
- P = 0.003
- Baseline rSO2 significantly associated with mortality, mean (SD) 51 (15) vs 64 (8)
- P < 0.001
- Mortality prediction by baseline rSO2, AUC
- 0.801 (p = 0.021)
