Changes in muscle metabolism lead to weakness and reduced mobility of the diaphragm, which exacerbates the progression of respiratory failure.</p> <p><bold>Aim.</bold> To evaluate the effect of a meglumine sodium succinate 1.5% solution on the dynamics of metabolic blood parameters and respiratory function of the lungs in patients with COVID-19.</p> <p><bold>Material and methods.</bold> The observational prospective study included 105 patients with severe COVID-19 treated in the intensive care unit. As an infusion therapy, patients in the control group (n=54) received Ringer's solution, in the main group (n=51) — 1.5% solution of meglumine sodium succinate. Infusion therapy was carried out for 11 days. All patients underwent standard laboratory tests. Diaphragm mobility was assessed using an ultrasound scanner. Intergroup comparisons were performed using the Mann–Whitney test, and intragroup dynamics were assessed using the Kruskal–Wallis test.</p> <p><bold>Results.</bold> Upon admission to the intensive care unit, in 36.2% of patients, the development of respiratory failure was accompanied by a decrease in the excursion of the right dome of the diaphragm to less than 1.7 cm, in 92.4% of patients — the development of hyperglycemia and hyperlactatemia. By the 11th day of ongoing treatment, hyperglycemia persisted in 16.7% of patients in the control group and 3.9% of patients in the main group, hyperlactatemia — in 53.7 and 9.8% of patients, respectively. Maintenance and then gradual restoration of diaphragm excursion in patients of the main group, a decrease in hypercapnia and a gradual increase in the pO2/FiO2 index were registered. Therapy with a solution of meglumine sodium succinate significantly reduced the duration of hospital treatment after transfer from the intensive care unit (p=0.007).</p> <p><bold>Conclusion.</bold> The inclusion of a 1.5% solution of meglumine sodium succinate in the therapy of patients with severe COVID-19 can reduce the duration of metabolic disorders, which has a positive effect on the degree of respiratory dysfunction, diaphragmatic excursion depression and the treatment duration after transfer from the intensive care unit.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность.</bold> Метаболические расстройства, часто выявляемые у пациентов с тяжёлым течением коронавирусной инфекции COVID-19, указывают на тяжесть инфекционного процесса и играют важную роль в патогенезе заболевания. Изменения в метаболизме мышц приводят к слабости и снижению подвижности диафрагмы, что усугубляет прогрессирование дыхательной недостаточности.</p> <p><bold>Цель.</bold> Изучить влияние 1,5% раствора меглюмина натрия сукцината на динамику метаболических показателей крови и респираторную функцию лёгких у пациентов с COVID-19.</p> <p><bold>Материал и методы исследования.</bold> В наблюдательное проспективное исследование включены 105 пациентов с тяжёлым течением COVID-19, получающих лечение в условиях отделения реанимации и интенсивной терапии. В качестве инфузионной терапии пациенты контрольной группы (n=54) получали раствор Рингера, в основной группе (n=51) — 1,5% раствор меглюмина натрия сукцината. Инфузионную терапию проводили 11 сут. Всем пациентам назначали стандартные лабораторные исследования. С помощью ультразвукового сканера оценивали подвижность диафрагмы. Межгрупповые сравнения проведены при помощи критерия Манна–Уитни, оценка внутригрупповой динамики — с помощью критерия Краскела–Уоллиса.</p> <p><bold>Результаты.</bold> При поступлении в отделение реанимации и интенсивной терапии у 36,2% пациентов развитие дыхательной недостаточности сопровождалось снижением экскурсии правого купола диафрагмы менее 1,7 см, у 92,4% пациентов — развитием гипергликемии и гиперлактатемии. На фоне проводимого лечения к 11-м суткам гипергликемия сохранялась у 16,7% пациентов контрольной группы и 3,9% пациентов основной, гиперлактатемия — у 53,7 и 9,8% пациентов соответственно. Зарегистрированы поддержание, а затем и постепенное восстановление экскурсии диафрагмы у пациентов основной группы, снижение гиперкапнии и постепенный рост индекса рО2/FiО2. Терапия раствором меглюмина натрия сукцината достоверно сократила сроки лечения в стационаре после перевода из отделения реанимации и интенсивной терапии (р=0,007).</p> <p><bold>Вывод.</bold> Включение 1,5% раствора меглюмина натрия сукцината в состав терапии у пациентов с тяжёлым течением COVID-19 позволяет сократить продолжительность метаболических нарушений, что оказывает положительное влияние на степень респираторной дисфункции, депрессии экскурсии диафрагмы и сроки лечения после перевода из отделения реанимации и интенсивной терапии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>lactate</kwd><kwd>glucose</kwd><kwd>meglumine sodium succinate</kwd><kwd>ultrasound</kwd><kwd>diaphragm</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>лактат</kwd><kwd>глюкоза</kwd><kwd>меглюмина натрия сукцинат</kwd><kwd>УЗИ</kwd><kwd>диафрагма</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Carrasco-Sánchez FJ, López-Carmona MD, Mar­tínez-Marcos FJ, Pérez-Belmonte LM, Hidalgo-Jiménez A, Buona­iuto V, Suárez Fernández C, Freire Castro SJ, Luordo D, Pesqueira Fontan PM, Blázquez Encinar JC, Magallanes Gamboa JO, de la Peña Fernández A, Torres Peña JD, Fernández Solà J, Napal Lecumberri JJ, Amorós Martínez F, Guisado Espartero ME, Jorge Ripper C, Gómez Méndez R, Vicente López N, Román Bernal B, Rojano Rivero MG, Ramos Rincón JM, Gómez Huelgas R; SEMI-COVID-19 Network.
