METHOD FOR DETERMINING THE RISK OF POSTOPERATIVE BRAIN DYSFUNCTION IN ONCOSURGERY Russian patent published in 2022 - IPC A61B10/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to operative oncology. Prognostically valuable factors are determined, namely: age over 75 years (A), for which the probability of developing postoperative cerebral dysfunction is 69.03%; maximum systolic blood pressure intraoperatively more than 150 mmHg (B), for which the probability of developing postoperative cerebral dysfunction is 70.76%; compliance with the antihypercholesterolemic diet (C), for which the probability of developing postoperative brain dysfunction is 1.11%: a protective factor. Then the probability of the risk of developing postoperative brain dysfunction is determined with a combination of the above factors, namely: with a combination of factor A + C, 15.33%; with a combination of factor B + C, 16.43%; with a combination of factors A + B + C, 75.98%; with a combination of factor A + B, 97.5%. At the final stage, patients are stratified into groups of “low” and “high” risks. At the same time, the “low” risk group includes patients with a risk probability of developing postoperative brain dysfunction of less than 20%, and the “high” risk group includes patients with a risk probability of developing postoperative brain dysfunction of more than 20%.

EFFECT: method makes it possible to more accurately determine the risk of developing postoperative brain dysfunction by taking into account all possible combinations of risk factors.
