What are the potential effects of cardiopulmonary bypass on the number of cerebral microemboli and the incidence of cognitive dysfunction after coronary artery bypass graft surgery?
A 2009 study conducted by Liu YH, Wang DX, Li LH, et al. investigated the effects of cardiopulmonary bypass on the number of cerebral microemboli and the incidence of cognitive dysfunction after coronary artery bypass graft surgery. The results showed that cardiopulmonary bypass can increase the number of cerebral microemboli and the incidence of cognitive dysfunction after coronary artery bypass graft surgery. Furthermore, they found that the incidence of cognitive dysfunction after coronary artery bypass graft surgery was significantly higher in patients who had undergone cardiopulmonary bypass compared to those who had not. Additionally, the study found that the incidence of cognitive dysfunction was associated with the duration of cardiopulmonary bypass. Therefore, it is important to consider the potential effects of cardiopulmonary bypass on the number of cerebral microemboli and the incidence of cognitive dysfunction when performing coronary artery bypass graft surgery.
