The duration of ScO2 values < 50% or a drop > 20% from baseline were associated with the occurrence of early perioperative global cerebral ischemia within three days after cardiothoracic surgery.
Study context
- Population
- Consecutive cardiothoracic surgery patients with routine perioperative ScO2 (near-infrared spectroscopy (NIRS)) monitoring admitted to Intensive Care Unit (ICU), 2008–2017, with confirmed anterior circulation stroke on brain imaging39 with anterior stroke
- Participants
- 2,454 patients
- Exposure
- Stroke-affected vs non-affected hemispheres
- Affectedn = 44
- Non-affectedn = 34reference
- Outcome
- Association of intraoperative ScO2 (AUC, duration and total excursions below < 50% or > 20% reduction from baseline) with early perioperative stroke
- Follow-up
- Within three days after cardiothoracic surgery
