Objective. assessment of the evolution of the microbiological landscape of the hospital for the period of operation in 2020 into a pandemic of a new coronavirus infection in various departments, including intensive care units; change depending on the results of antibacterial therapy regimens. Materials and Methods. In a retrospective study, conducted from June to December 2020, in a multidisciplinary hospital working with COVID-19 infection, the resistance of isolated strains of microorganisms was analyzed in patients of different age groups. Resistance was assessed with test points in June and November 2020; depending on this, proposals were made to correct the internal (local) protocols of antimicrobial therapy. Results. The need for frequent and regular microbiological monitoring was confirmed. Further, we understood that the territories of the main and temporary hospital of the City Clinical Hospital No. 40 are heterogeneous and there are obvious differences both in structure and in the level of sensitivity. “In practice, these are two different hospitals”. Within the territories, the branches also differ from each other. When analyzing resistance in ICUs, it was revealed that within each hospital in each department, albeit similar in structure and profile of patients, there is a different level of resistance of strains. Conclusions. The structure of sensitivity generally corresponds to the world data, but for some pathogens it differs significantly. Microbiological monitoring should be carried out not only inside the hospital, but also inside the department. The increase in consumption of carbapenems and protected cephalosporins requires a reassessment of the practice of using AMP in any covid hospital, due to the impact on the epidemic situation both in the ICUs and in the hospital.

<p><strong>Aim.</strong> To evaluate the dynamics and prognostic significance of serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) level in patients with severe abdominal sepsis.</p><p><strong>Methods.</strong> We analysed survey data of 54 patients (28 men and 26 women) aged 64.5 years [56.25–78.00] with abdominal sepsis or septic shock. Disease severity scored according to the Acute Physiology and Chronic Health Evaluation II criteria was 16.3 ± 0.8 and according to the Sequential Organ Failure Assessment (SOFA) was 3 [3–6]. Statistical analysis of these data was performed using correlation analysis, logistic regression and receiver operating characteristic analysis.</p><p><strong>Results.</strong> Serum NT-proBNP level during the 1st week following admission to the intensive care unit (ICU) exceeded normal values, i.e. 2,570 [116.25–6,559.5] to 4,600 [1,680–18,200] pg/ml. At all disease stages, serum NT-proBNP level correlated with sepsis severity scores (SOFA), procalcitonin (PCT) levels, lactatemia, mean arterial pressure, heart rate and inotropic and vasoactive–inotropic scales (rho = 0.329–0.433; p &lt; 0.02). On ICU days 3–4, serum NT-proBNP level of &gt;5100 pg/ml was associated with increased risk of mortality [65.6%–88.2%; area under the curve (AUC) = 0.806; р &lt; 0.0001]. Similarly, during this interval, elevated serum NT-proBNP level was associated with the use of inotropic drugs (OR = 1.0001, 95% CI = 1.000–1.0002, p &lt; 0.0059). Notably, we found that 76.9%–79.0% of the patients with serum NT-proBNP level of &gt;5250 pg/ml were receiving inotropic drugs including adrenaline, dopamine and dobutamine. We were unable to identify a specific association between serum NT-proBNP level and norepinephrine administration. On ICU days 7 and 8, among patients with serum NT-proBNP level of &gt;3450 pg/ml, we observed a very close relationship between serum NT-proBNP level and PCT (sensitivity = 63.6%, specificity = 66.7%, AUC = 0.708; р = 0.0041).</p><p><strong>Conclusion.</strong> Serum NT-proBNP level is considerably elevated in patients with abdominal sepsis or septic shock. NT-proBNP level was associated with both traditional indicators of sepsis severity and indicators characterising the state of systemic circulation. Notably, serum NT-proBNP level correlates with cardiac failure and inotropic drug requirement. Although the mechanisms underlying the observed increases in serum NT-proBNP level remain unclear, the present findings indicate that this mediator is clearly a significant biomarker and predictor of adverse outcomes related to abdominal sepsis and septic shock.<br /><br />Received 22 January 2020.

INTRODUCTION. The literature has accumulated enough data on the treatment of children with acute bronchiolitis (OB). However, this information is formed mainly on the general population of patients with OB and is often not applicable to patients with a severe course of the disease. From the standpoint of evidence-based medicine, routine use of medications is not recommended in modern consent documents, and there are also no clear recommendations on respiratory support and certain aspects of intensive care in children with OB. OBJECTIVES. To analyze approaches to therapy in children with severe acute course in need of intensive care, and to assess the validity, effectiveness and safety of the use of the analyzed groups of drugs and respiratory strategies. MATERIALS AND METHODS. The analysis of publications in the electronic databases PubMed and the Russian Scientific Citation Index on the keywords “bronchiolitis”, “intensive care units”, “critical care”, “fluid therapy”, “respiratory therapy”, “ventilation”, “co-morbidity”; “respiratory syncytial virus”; “hypertonic saline” was carried out, “corticosteroids”; “epinephrine”; “high-flow oxygen therapy”, “inhalation”, “infant”, “bronchiolitis in children”. The date of the last search is January 15, 2022. RESULTS. This systematic review provides information on the etiology and risk factors of severe acute respiratory syndrome in children, from the standpoint of evidence-based medicine, studies on the treatment of severe acute respiratory syndrome are characterized, including in the intensive care unit with glucocorticosteroids, inhalations of bronchodilators, epinephrine, 3 % hypertonic sodium chloride solution, respiratory support, high-flow oxygenation, noninvasive ventilation, artificial ventilation, antibiotics, air-helium mixture. CONCLUSIONS. Currently, there is more information that infants with OB show a high degree of heterogeneity, while the main uncertainty lies in a misunderstanding of the processes, which patients will benefit most from a particular treatment method. Further research is needed to fill the research deficit in children with a severe course of OB.

Introduction. The prevalence of rhabdomyolysis among people admitted to the hospital due to acute poisoning reaches, according to various foreign sources, from 30 to 40%. In 60% of cases, the development of rhabdomyolysis in adult patients is associated with acute exogenous intoxication. Currently, data on the prevalence, structure and outcomes of treatment of rhabdomyolysis in toxicological patients are mainly presented by the results of foreign clinical and epidemiological studies. The aim is to study the prevalence, structure, frequency of complications and outcomes of treatment of rhabdomyolysis in acute exogenous intoxication in a multidisciplinary hospital. Material and methods. The study included 1,363 patients who were treated from 2017 to 2020 with acute exogenous intoxication. During the study, 98 patients with rhabdomyolysis were selected from the general group. The frequency of poisoning with various toxicants was analyzed, the effects of which led to the development of rhabdomyolysis in acute exogenous intoxication. The incidence of acute kidney injury (AKI) was detected, the outcomes of acute poisoning treatment, the duration of inpatient treatment were determined, and a comparative analysis was carried out between groups of patients with rhabdomyolysis in acute exogenous intoxication (n=98) and without it (n=1265). Results. The prevalence of rhabdomyolysis among patients hospitalized for acute poisoning was 7%. The main reason for the development of rhabdomyolysis was the use of narcotic drugs - 87% of cases. The development of rhabdomyolysis in acute exogenous intoxication in 59.2% of cases is accompanied by the occurrence of AKI, which is significantly higher than among patients without rhabdomyolysis (11.6%). The occurrence of rhabdomyolysis in toxicological patients increases hospital mortality from 6.1 to 10.2%, as well as the duration of inpatient treatment and intensive care by 5.2 and 3.3 days, respectively. Limitations. The study was conducted based on only one multidisciplinary hospital in Moscow in the period from 2017 to 2020. Conclusion. Rhabdomyolysis is a serious complication of acute poisoning, the development of which significantly worsens the outcomes of treatment of patients with a toxicological profile, which requires the development of effective methods for the prevention, diagnosis and treatment of rhabdomyolysis in acute exogenous intoxication.
