Cardiothoracic & vascular anesthesia
Association between regional oxygen saturation and central venous saturation in pediatric patients undergoing cardiac surgery: A prospective observational study
Authors' conclusion
Cerebral rSO2 , SpO2 , and BNP were significantly correlated with ScvO2 , although the cerebral rSO2 correlation was greater for lesions without atrial mixing.
Study context
- Population
- Children (weight < 10 kg) undergoing cardiac surgery for congenital heart disease, February 2018 to November 2021
- Participants
- 33 children
- Exposure
- Cerebral and somatic rSO2 vs ScvO2
- Outcome
- Correlation and agreement (Pearson's correlation, Bland-Altman) between rSO2 and ScvO2
- Follow-up
- After anesthesia induction and central venous catheter placement
