A Prospective Observational Study on the Effect of Emboli Exposure on Cerebral Autoregulation in Cardiac Surgery Requiring Cardiopulmonary Bypass.
Overall, change in mean velocity index before and after cross-clamp removal did not differ between groups. However, most emboli entered the right cerebral hemisphere where this change was significantly greater in the open-chamber group, suggesting a possible association between embolic exposure and dysautoregulation.
