Features of the Functional State of the CNS and Efficiency of Medical Workers of PCR Laboratories During Covid-19 Pandemic

Abstract

The functional state of the central nervous system was determined by the method of variational chronoreflexometry. The calculated criteria for assessing the functional level of the nervous system (FLS, conventional units), the stability of the nervous reaction (SR, conventional units), the level of functional capabilities of the formed functional system (LFC, conventional units) were analyzed. The observation group was made up of medical workers of PCR laboratories during the COVID-19 pandemic. The results were processed by the variational-statistical method with the calculation of average values (M), representativeness errors (±m), the reliability of differences was determined by the Student's t-test using applied statistical packages Statistica 6.0. It was found that the functional state of the central nervous system in PCR laboratory workers is characterized by the development of significant fatigue and depletion of the functional reserves of the central nervous system, as evidenced by a significant decrease in the level of the formed functional system (FSL) from 2.40±0.04 to 2.13±0.095 units, the stability of the reaction (SR) to 66.25-74.54%. The ability of the central nervous system to form and maintain an adaptive functional system of adaptation to environmental factors significantly decreased by the end of the shift in the observation group by 43.12%- 48.01%. The identified features of the functional state of the central nervous system and the working capacity of medical workers in PCR laboratories during the COVID-19 pandemic will be used for further causation of changes in their health status in difficult working conditions.
