Are near-infrared spectroscopy (NIRS)-derived cerebral autoregulation and ABPopt values different between hemispheres in hypoxic-ischemic brain injury patients following cardiac arrest?
Authors' conclusion
We found no differences between left and right-sided NIRS recordings or CA estimation in comatose and ventilated HIBI patients.
Study context
- Population
- Comatose, ventilated patients with hypoxic-ischemic brain injury (HIBI) after cardiac arrestABPopt compared in 9
- Participants
- 11 participants
- Exposure
- Left vs right-sided bifrontal NIRS recordings
- Outcome
- Differences in NIRS-derived cerebral autoregulation (CA) (COx) and ABPopt values between left and right-sided recordings
Methodological detailspaired comparison of left vs right recordings, Average recording time 26 (IQR, 22-42) hours
- Paired comparison of left vs right recordings
- Average recording time 26 (IQR, 22-42) hours
Main finding
As reported in the abstract
ABPopt, left vs right NIRS recordings
P = 1.0
- Intraclass correlation coefficients (ICC) for ABPopt (agreement between bifrontal recordings), high
- 0.95
- ICC for ABPopt, interval
- 0.78-0.98
- ICC for ABPopt, P
- P < 0.001
Observational data: associations, not effects.
Further findings
rSO2 and COx
- Similar results to ABPopt (no left-right difference, high agreement)
- Compared in 10 patients
