Abstract

The occurrence of cognitive disorders is a common problem after surgery. The degree of worsening of cognitive functions after surgery and anesthesia has a significant impact on the patient's health and is significantly associated with prolonged recovery in the hospital, increased morbidity and delayed functional recovery. The aim of the study was to increase the effectiveness of the diagnosis of moderate cognitive impairment and to determine its gender and age characteristics in patients before and after cardiac surgery in the early postoperative period (3 and 7 days). We examined 56 patients who underwent cardiac surgery for coronary heart disease in 37 (66.1 %) and valvular heart defects in 19 (33.9 %) patients. Assessment of cognitive functions was performed before surgery, on the 3rd and 7th day of the postoperative period. Testing was performed using the Montreal Cognitive Test. Statistical processing of the obtained data was performed on a personal computer using the statistical software package SPSS 12.0 for Windows using parametric and non-parametric methods. It was found that presence of cognitive disorders before surgery was registered in 37 (66.1 %) patients, mostly among the age of group of 60-74 years and had no gender difference. It was found that in the early postoperative period there is a significant worsening of cognitive functions in patients after cardiac surgery on 3rd day – in 45 (80.4 %), on 7th day – in 44 (78.6 %) patients, respectively.
