Evaluating the efficacy of intraoperative near-infrared spectroscopy (NIRS) cutoff values in detecting spinal cord ischemia during surgery
Authors' conclusion
In this limited cohort, intraoperative NIRS cutoff values did not significantly correlate with postoperative neurological deficits following TAAA repair.
Study context
- Population
- Patients undergoing open thoracoabdominal aortic aneurysm (TAAA) repair17 included
- Participants
- 25 patients
- Exposure
- Intraoperative spinal NIRS drops vs postoperative neurological outcome
- New neurological deficitsn = 7
- Outcome
- Association between significant NIRS drops (<80% of baseline) and postoperative neurological outcomes (paralysis, hemiparesis or extremity weakness)
Methodological detailsBayesian analysis, 8 patients excluded for poor signal quality
