Acute cardiac care & resuscitation
Association between burst-suppression with identical bursts and multimodal measures of cerebral oxygenation after cardiac arrest
Authors' conclusion
BSIB may represent a distinct subtype of PCABI characterized by impaired oxygen metabolism with preserved oxygen delivery and diffusion.
Study context
- Population
- Patients resuscitated from cardiac arrest who underwent EEG and SjvO2 or PbtO2 monitoringSjvO2 and PbtO2 cohorts · SjvO2 cohort 109 · PbtO2 cohort 33
- Exposure
- Associations between EEG and SjvO2, PbCO2 gap, PbtO2, and intracranial pressure (ICP)
- Outcome
- SjvO2

PbtO2
- PbtO2 was highest with BSIB
