The aim – to analyze the therapeutic efficacy of veno-venousextracorporeal membrane oxygenation(ECMO) in patients with acute respiratory distress syndrome (ARDS) caused by SARS-CoV-2.

Materials and methods. A retrospective analysis of patients with acute lung injury because of COVID-19, receiving veno-venous ECMO treatment from February 2020 to May 2021, was carried out.

Results. During thе period of the study, seven cases of veno-venous ECMO connection due to ARDS were recorded. Clinically they fell under the manifestations of COVID-19 infection. The most frequent complication during ECMO was thrombosis in the ECMO system – 42.9 %, which required replacement of the oxygenator – in two cases and replacement of the ЕСМО-system – in one case. Three patients had bleeding at the cannulation site in combination with epistaxis or gastrointestinal bleeding. In general, the mortality rate for ECMO among the examined patients was 57.1 %, while the 30-day mortality rate was 71.4 %.

Conclusions. Early consultation with ECMO center is a key strategy in the effective treatment of patients with COVID-19 with severe respiratory failure. However, the criteria for selecting such patients for ECMO, as well as the optimal strategy for anticoagulation therapy, remain unclear.

Key words: extracorporeal membrane oxygenation, acute respiratory distress syndrome, СOVID-19.
