Abstract

The purpose of this study was to study changes in the structure of postoperative cognitive dysfunction (POCD) in cardiac surgery patients under the influence of multitask training.

Material and methods. The cohort sample study involved 90 patients who underwent elective coronary artery bypass grafting (CABG), who were divided into two groups: the control group with standard postoperative care (n = 45) and the main group (n = 45), which, starting with 3–4 days after CABG, a course of cognitive rehabilitation was conducted using multi-task training.

Results. It was found that the combined disorders of psychomotor and executive functions, short-term memory and attention were more common in the control group than in the group with multitask training, χ2 = 4.12, p = 0.04. However, the training group patients more often showed impairments in the combination of two domains – attention and memory than in the control group, χ2 = 5.1, p = 0.02.

Conclusion. The structure of POCD in cardiac surgical patients after a course of multitask training changed towards a lower frequency of combined cognitive decline in three domains (neurodynamics, attention and memory), but the percentage of attention and memory impairments increased compared to the control group. Possible reasons for the identified changes in the structure of POCD may be the limited physical and cognitive resources of patients, as well as the selection of multitask training components, which had a greater impact on executive and psychomotor functions.
