AbstractParameters of cognitive evoked potentials P300 were studied in 40 patients with ischemic heart disease subjected to coronary artery bypass graft surgery in conditions of cardiopulmonary bypass before and 7-9 days after operation. Patients underwent also neurological and neuropsychological examination. The most significant P300 parameters proved to be P3 and N2 latency, an increase of which correlated with the level of developing cognitive deficiency. A neuroprotective effect of Tracilol during the surgery was confirmed. In patients receiving this drug, cognitive deficiency and changes of P300 parameters were less pronounced. A study of cognitive evoked potentials P300 may be recommended for detecting early cognitive dysfunction and estimation of neuroprotective therapy in patients operated on in conditions of cardiopulmonary bypass.
