Acoustic assessment of pulmonary ventilation in children with bronchial asthma on the background of a single exposure to microwave radiation

Abstract

Summary. Diseases of the respiratory organs of children, occurring with obstructive syndrome, represent one of the most serious problems in terms of transition to chronic forms. The chronic process is accompanied by a decrease in pulmonary ventilation, which leads to the search for effective methods of complex therapy of diseases.
 The purpose of this study was to evaluate the dynamics of acoustic indicators of pulmonary ventilation in children with bronchial asthma, against the background of non-invasive non-thermal microwave radiation.
 Materials and methods. 122 children with bronchial asthma aged from 3 to 17 years were examined. 113 patients underwent a single session of non-invasive microwave therapy with the Aster device. Comparison of acoustic characteristics of pulmonary ventilation was carried out taking into account the severity of the disease and the age of children with bronchial asthma. Acoustic assessment of ventilation function was performed using the computer bronchophonography complex Pattern-01 before the Aster procedure, after 5 and 15 minutes. In 20 (16.4%) patients with bronchial asthma, the dynamics of cough was evaluated against the background of Aster therapy for 7 days.
 Results. Improvement of bronchial patency was registered in all age groups with mild bronchial asthma. In the group of moderate asthma, exposure to electromagnetic radiation led to a significant reduction in ventilation disorders in children aged 711 years. As patients grow older, as well as with severe bronchial asthma, the smallest dynamics of the parameters of pulmonary ventilation was observed against the background of Aster therapy. The use of electromagnetic radiation in addition to traditional basic therapy for 7 days leads to a faster regression of cough in patients with bronchial asthma.
 Conclusion. The combination of traditional basic therapy with electromagnetic non-thermal radiation in patients with bronchial asthma reduces obstructive pulmonary ventilation disorders and promotes faster cough regression.
