Perioperative Near Infrared Spectroscopy Measurements of Cerebral Regional Oxygen Desaturations Are Not Associated With Delirium After Cardiac Surgery
Authors' conclusion
Neither baseline nor intraoperative near-infrared spectroscopy-measured cerebral rSO2 parameters were associated with postoperative delirium.
Study context
- Population
- Adults aged 18 and older undergoing cardiac or open ascending thoracic aortic surgery, January 2016–April 2023, single tertiary care institutionincluded in the analysis
- Participants
- 3,696 adults
- Exposure
- rSO2 desaturation vs none
- Outcome
- Association of rSO2 with postoperative delirium
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
- Neither baseline rSO2 nor any perioperative rSO2 desaturation incidences or durations associated with postoperative delirium
Observational data: associations, not effects.
Further findings
Other factors associated with delirium
- Age, cerebral vascular disease, preoperative cognitive impairment, dexmedetomidine use, and durations of CPB and BIS values <40 associated with delirium
