Implication

Retrospective study finds lower stroke incidence in cardiac surgery patients with cerebral oximetry, indicating targeted oxygen optimization protects the brain.

Key Points

To determine whether intraoperative optimization of cerebral oxygen delivery using noninvasive cerebral oximetry decreases stroke incidence in cardiac surgery patients.
Retrospective comparative study evaluating cardiac surgery patients monitored with noninvasive cerebral oximetry to maintain baseline saturation (n = 1,034; January 2002–June 2003) versus an unmonitored historical control cohort (n = 1,245; July 2000–December 2001).
Surgical teams adjusted intraoperative oxygen delivery and consumption parameters to keep cerebral oximetry values at or near preinduction baselines, evaluating permanent stroke defined by Society of Thoracic Surgeons criteria.
Permanent stroke occurred in 10 patients (0.97%) in the oximetry-guided group compared to 25 patients (2.5%) in the control group (P < .044), an effect that remained significant after adjusting for NYHA functional class and on-pump or off-pump status.
The oximetry-guided group experienced significantly lower rates of prolonged mechanical ventilation (6.8% vs. 10.6%; P < .0014) and significantly shorter hospital stays (P < .046).
