Abstract EN
Cardiac surgery is commonly associated with brain ischemia.
Few studies addressed brain electric activity changes after on-pump operations.
Eyes closed EEG was performed in 22 patients (mean age: 45.2±11.2) before and two weeks after valve replacement.
Spouses of patients were invited to participate as controls.
Generalized increase of beta power most prominent in beta-1 band was an unambiguous pathological sign of postoperative cortex dysfunction, probably, manifesting due to gamma-activity slowing (“beta buzz” symptom).
Generalized postoperative increase of delta-1 mean frequency along with increase of slow-wave activity in right posterior region may be hypothesized to be a consequence of intraoperative ischemia as well.
At the same time, significant changes of alpha activity were observed in both patient and control groups, and, therefore, may be considered as physiological.
Unexpectedly, controls showed prominent increase of electric activity in left temporal region whereas patients were deficient in left hemisphere activity in comparison with controls at postoperative followup.
Further research is needed in order to determine the true neurological meaning of the EEG findings after on-pump operations.
