Perioperative Low Arterial Oxygenation Is Associated With Increased Stroke Risk in Cardiac Surgery.
Both patient characteristics and intraoperative factors have been associated with a higher risk of stroke after cardiac surgery. We hypothesized that poor systemic oxygenation in the perioperative period is associated with increased risk of stroke following cardiopulmonary bypass. ⋯ Odds of stroke after cardiac surgery are increased in patients with a low minimum PaO2 within 24 hours of surgery. Results should be validated in an independent cohort. Further characterizing the underlying etiology of hypoxic episodes will be important to improve patient outcomes.
