Abstract
Relevance. Postoperative cognitive dysfunction (POCD) (decreased memory, attention, impaired neurodynamics, etc.) is a common complication especially in elderly patients of cardiosurgical and oncosurgical pathology, which reduces the quality of life and is an actual socially significant problem. Computer electroencephalography (EEG) is an informative method for assessing the functional state of the brain. Patients with cancer and competing cardiovascular pathology have the opportunity to perform staged or simultaneous operations on the heart and lung for further antitumor treatment.
Objective. Based on the literature data, to find out the role of EEG in diagnosis of postoperative cognition dysfunction (POCD) in patients with cardiovascular pathology after cardiac surgery without /under conditions of AC.
Methods. We found and analyzed data in specialized medical data base Pubmed, Scopus, Web of Science about EEG methods in patients after heart bypass with/without AC from 2004 to 2025 years.
Results. Computer EEG is very important for early diagnosis and prognosis for postoperative cognitive dysfunction in patients with coronary heart disease (CHD) after coronary artery bypass with/without AC. However, the studies did not included patients with oncopathology, people over 70 years of age. It opens possibilities for early diagnosis of central nervous system functional conditionin patients with lung cancer and cardiovascular disorders in simultaneous (concomitant heart and lung with/without AC) surgery.
