Cardiothoracic & vascular anesthesia
Can near infrared spectroscopy (NIRS) be a surrogate indicator of elective shunt in carotid endarterectomy? A single-center observational retrospective study says no
Authors' conclusion
NIRS is inferior to multimodality IONM in detecting brain ischemia and predicting postoperative neurological status during CEA under general anesthesia.
Study context
- Population
- Consecutive patients undergoing carotid endarterectomy under GA
- Participants

- Comparison
- NIRS vs multimodality intraoperative neuromonitoring
- Outcome
- Detection of brain ischemia (indication of elective shunt) and prediction of postoperative neurological status: sensitivity, specificity, PPV, NPV
Methodological detailssingle-centre, consecutive patients
- Single-centre
- Consecutive patients

Further findings
| Outcome | Values |
|---|---|
| Prediction of postoperative outcome, EEG alone (within multimodality IONM) | EEG PPV 100% · NPV 100% |
Prediction of postoperative outcome, EEG alone (within multimodality IONM)
- EEG showed the best results among IONM methods
Demographic or clinical data, true-positive vs false-positive patients
- No significant difference
