INFLUENCE OF MINE-BLAST INJURY AND COMBAT STRESS ON THE STATE OF THE VEGETATIVE NERVOUS SYSTEM

Aim. In order to study the disorders of the autonomic nervous system as a result of mine-blast trauma and combat stress, as well as to analyze the dependence of the manifestation of these disorders on the age and duration of the injury, 62 people were examined. Materials and methods. The main group consisted of 37 servicemen with mine-blast trauma (MBT) and surgical interventions, and the control group consisted of 25 civilian men. The age of the subjects ranged from 18 to 45 years. The state of the autonomic nervous system was determined using ANS Analysis equipment and included three main parameters: resting heart rate, sympathetic nervous system parameters, and parasympathetic nervous system parameters. The significance of the difference between the groups of results was checked using the Mann-Whitney test, and the relationship between them, the age of patients and the time interval from the injury was checked using the Spearman rank correlation coefficient. Results. According to the results of the study, changes in the autonomic nervous system indices were absent in the group of civilians, while significant changes in the ANS indices in the group of servicemen with combat trauma were found for all three parameters: heart rate, sympathetic and parasympathetic autonomic nervous system indices. Also, in the group with MBT, a pronounced dissonance between the indicators of the autonomic nervous system was revealed: against the background of a significant increase in sympathetic status, a significant decrease in parasympathetic status was observed (179,0 (57,5; 309,0) vs. 13,0 (10,0; 28,0). Changes in the indicators of autonomic nervous system with combat trauma did not depend on the age of patients. Instead, there was a weak but statistically significant positive correlation between the duration of the injury and the parasympathetic nervous system: rs=0.325 (p=0.049). Therefore, the early use of a set of measures that increase the activity of the parasympathetic nervous system is logical. Conclusions. There were no changes in the autonomic nervous system parameters in the civilian group, but significant changes in the ANS parameters were found in the group of military personnel with combat trauma.
