THE IMPORTANCE OF MODIFIED BRONCHOPHONOGRAPHY IN THE DIAGNOSIS OF RECURRENT BRONCHOOBSTRUCTIVE SYNDROME IN CHILDREN

Abstract

Abstract. Purpose of the study: to establish the diagnostic and prognostic significance of modified bronchophonography in bronchobstructive syndrome in children. Material and methods of research. The paper presents the results of examinations of children with bronchoobstructive syndrome. The patients were divided into 3 groups of 60 patients: Group I - patients with acute obstructive bronchitis (AOB), acute bronchiolitis (ABL), Group II - children with recurrent obstructive bronchitis (ROB) and bronchial asthma (BA), Group III - patients with acute bronchitis without bronchial obstruction (BA). Results of the study and discussion. Analysis of modified bronchophonography indices in groups I-II showed that on admission, E:I index>1.6 indicating bronchial obstruction of the II degree (P<0.001). On the 2nd day of observation, E:I index significantly decreased in patients with ROB, BA and was significantly lower in comparison with indices of patients with OOB, OBL (P<0,05). On the 3rd day of observation and at discharge, the indices were relatively equal, no significant difference was observed (P>0.2; P>0.1). When constructing the ROC-curve and analysing the curve coordinates, it was found that in determining the risk of ROB and AD in children, the diagnostic significance of the E:I index≥1.78, with a sensitivity of 71.7% and specificity of 61.1%. Conclusions. The values of E:I index≥1.78 are predictors of the risk of ROS and BA development, the diagnostic significance of which is confirmed by high sensitivity and specificity, which can be recommended for detecting the risk of recurrent course of BOS in children.
