Слуховая функция недоношенных детей различного возраста гестации в течение первого года жизни

Abstract

The frequency of the birth of premature babies is increasing every year; respectively, the quality and provision of care to such children are improving. Objective. To trace the dynamics of objective indicators of the functional state of the auditory analyzer during the first year of life in premature infants with different gestation periods in order to identify numerical values characterizing the functioning of the auditory analyzer in the first year of life in premature infants. Patients and methods. During the work, the auditory response was analyzed during the first year of life in 291 premature babies, of which 150 children with a gestation period of less than 28 weeks, 52 children born with a gestation period of 29 to 31 completed weeks, 47 children with a gestation period of 32 to full 34 weeks, 41 children with a gestational age of 35 to 36 weeks. The study was conducted at 3, 6, and 12 months of age. Audiological studies were carried out on the Eclipse device (Interacoustics, Denmark) in the state of physiological sleep of the child, ABR (Auditory Brainstem Response), ASSR (Auditory Steady-State Response) were recorded. Among the ABR indicators, the following were processed: threshold values of the V peak, latent values of the III and V peaks, peak-to-peak intervals between the III and V peaks at intensities from the threshold value to 60 dB. When registering ASSR, threshold responses at the tested frequencies and the average response threshold were determined. Results. In the course of the work, it was shown that the average threshold values for all premature babies in one year of life according to ABR data are 22,7 ± 6,3 dB; ASSR, 21,3 ± 5,9 dB.
