TO CHARACTERISTICS OF THE ETIOLOGICAL STRUCTURE AND ANTIBIOTIC SENSITIVITY PATHOGENSOF INFECTIOUS RESPIRATORY ORGANS IN NEWBORN AFTER ARTIFICIAL PULMONARY VENTILATION

Objective. The study of the etiological structure, properties of pathogens of the Vinnytsia National Medical University named after E. Pirogova, respiratory process in newborns who have underwent artificial mechanical lung ventilation (MLV) and their resistance to antibacterial agents is especially relevant in modern conditions, expands the search for new approaches to pathogens, improves treatment and reduces mortality from this pathology. The purpose of the study - to determine the etiological structure, sensitivity to antibiotics of the leading pathogens of the infectious process of the respiratory system in newborns who were on mechanical ventilation. Materials and methods. In total, the species composition of the leading microorganisms that colonized the airways of 180 newborns treated in the Neonatal Intensive Care Unit (VAITN) of Vinnytsia Regional Children’s Clinical Hospital (VRCCH) was studied in 2020. A total of 285 isolates of microorganisms were isolated. 62 patients who underwent mechanical ventilation were involved in a prospective microbiological study, 86 clinical strains of microorganisms were isolated. The susceptibility of microorganisms to 30 antibacterial agents was determined according to the generally accepted method (order of the Ministry of Health of Ukraine №167; recommendations). Research results. The etiological significance of opportunistic pathogens (Enterobacter cloacae - 29%, Staphylococcus aureus - 24.4%, Pseudomonas aeruginosa - 18.6%, Candida albicans) was proved in patients who were on mechanical ventilation in VAITN VRCCH in 2020 for pneumonia. Clinical strains of S. aureus are sensitive to vancomycin, oxacillin and clindamycin. Conclusions. Pathogens of the respiratory process in newborns who have been on mechanical ventilation, are resistant to a number of antibiotic drugs (cefepime, gentamicin amikacin, piperacillin).
