Association of oxygenation levels after successful mechanical thrombectomy under general anesthesia and 3-month functional outcome in patients with acute ischemic stroke: A prospective observational study
Authors' conclusion
No association was found between 3-mo functional outcomes and post-procedure oxygenation levels in patients with AIS treated successfully with EVT under general anesthesia.
Study context
- Population
- Mechanically ventilated patients with acute ischemic stroke (AIS) (proximal anterior circulation occlusion) after successful endovascular treatment (EVT) under GA, admitted to ICU for delayed extubationmet inclusion criteria
- Participants
- 210 participants
- Exposure
- PaO2 <150 mmHg vs PaO2 ≥150 mmHg within the first hour of ICU admission
- PaO2 <150 mmHgn = 100reference
- PaO2 ≥150 mmHgn = 108
- Outcome
- Favorable functional outcome (mRS ≤ 2)
- Follow-up
- 3 mo
