Цель. Изучение летальности и факторов риска смерти больных с COVID-19, госпитализированных для респираторной поддержки в отделения реанимации и интенсивной терапии (ОРИТ) лечебных учреждений Российской Федерации. Материал и методы. Ретроспективное исследование было выполнено в Федеральном дистанционном консультативном центре анестезиологии и реаниматологии для взрослых пациентов с COVID-19 на базе Первого МГМУ им. И.М. Сеченова. В исследование включали всех пациентов с известными исходами (смерть от любых причин или выздоровление) SARS-CoV-2 пневмонии, осложнившейся острым респираторным дистресс синдромом (ОРДС), которые были проконсультированы с 16 марта по 3 мая 2020 г. Факторы риска смерти анализировали с помощью многофакторной регрессионной модели Кокса. Результаты. В исследование были включены 1522 пациента, 864 (56,8%) мужчины и 658 (43,2%) женщин. Медиана возраста-62 года. 922 (60,6%) больных находились в ОРИТ стационаров Москвы и Московской области, 600 (39,4%)-лечебных учреждений в 70 регионах Российской Федерации. У 995 (65,4%) больных диагноз SARS-CoV-2 инфекции был подтвержден с помощью ПЦР. Умерли 995 (65,4%) пациентов, выжили 527 (34,6%). Основными причинами смерти были ОРДС (93,2%), сер
Aim. In a retrospective study, we evaluated factors associated with the early development of septic shock in patients with severe COVID-19.
Materials and methods. We collected medical records of the intensive care unit patients submitted by the local COVID-19 hospitals across Russia to the Federal Center for the Critical Care at the Sechenov First Moscow State Medical University (Sechenov University). Septic shock in crticially ill patients requiring mechanical ventilation was defined as a need in vasopressors to maintain blood pressure.
Results. We studied 1078 patients with severe COVID-19 who were admitted to the intensive care units for respiratory support. There were 611 males and 467 females. The mean age was 61.013.7 years. Five hundred twenty five medical records (48.7%) were received from the Moscow hospitals, 159 (14.7%) from the Moscow region, and 394 (36.5%) from the hospitals located in 58 regions of the Russian Federation. In 613 (56.9%) patients, diagnosis of SARS-CoV-2 infection was confirmed by PCR, and in the other cases it was established on the basis of the clinical picture and the results of the chest CT scan. Septic shock developed in 214 (19.9%) of 1078 patients. In the logistic regression model, the risk of septic shock in patients older than 50 years was higher than in patients of a younger age (OR 2.34; 95% CI 1.533.67; p0.0001). In patients with more severe SARS-CoV-2 infection, there was an increase in the prevalence of cardiovascular diseases, including coronary heart disease and atrial fibrillation, type 2 diabetes and malignant tumors. The risk of septic shock in patients with three or more concomitant diseases was higher than in patients without any concomitant chronic diseases (OR 1.76; 95% CI 1.762.70).
Conclusion. The risk of septic shock in patients with acute respiratory distress syndrome induced by SARS-CoV-2 is higher in patients older than 50 years with concomitant diseases, although a severe course of the disease is also possible in younger patients without any concomitant disorders.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
