Background. Klebsiella pneumoniae (K. pneumoniae) is one of the main causes of hospital infections (pneumonia, urinary tract infections, blood infections) in children with congenital heart disease in the intensive care unit. Multidrugresistant strains significantly complicate and treatment, but with rational antibiotic therapy it is possible to achieve effective treatment results.

The aim. To analyze the detection of different strains of K. pneumoniae in children with congenital heart disease in the intensive care unit and the principles of antibiotic therapy in the treatment of infections caused by them.

Materials and methods. At the Department Of Congenital Heart Disease Surgery for Newborns and Young Children, of the National Amosov Institute of Cardiovascular Surgery we examined 2548 patients in 2018-2020. Microbiological examination was performed in 370 children. Bacteriological culturing (sputum, blood) of the studied material on special medium for bacterial growth was analyzed on VITEK-2 analyzer for 72 hours. If a progenitor was seen, the sample was considered as positive, and the resulting columns were tested for sensitivity to antibiotics.

Results. The bacterial growth was positive in 277 (75%) children, of whom K. pneumoniae was found in 98 (25%) patients in 138 tests. We obtained the following data: K. pneumoniae in 79 (57%) patients, extended spectrum betalactamase (ESBL)-producing K. pneumoniae in 47 (34%), carbapenem-resistant K. pneumoniae in 11 (8%), multiresistant K. pneumoniae in 1 (1%) patient. We prescribed standard or specific therapy in accordance with the recommendations for the treatment of infections caused by K. pneumoniae and its susceptibility to the antibiotics.

Conclusions. It is important to follow the rules of rational antibiotic therapy (taking into account the sensitivity of the stimuli, pharmacodynamic and pharmacokinetic properties of the drugs) when treating infections. The spread of carbapenem-resistant strains of microorganisms leads to the loss of the possibility of using carbapenems as a reserve antibiotic, which significantly complicates the treatment of infections, and ceftazidime/avibactam should be the drug of choice in wards where the number of carbapenem-resistant strains equals to/exceeds 20%.
