Sequential Use of Hemadsorption Using Cytosorb® and Biosky® Filter-Technology in A COVID-19 Patient Suffering from Severe ARDS

In March 2020, the World Health Organization (WHO) declared the novel coronavirus disease (COVID-19) pandemic. Here, we present the case of a patient who was admitted to our hospital with acute respiratory distress syndrome (ARDS) following infection with COVID-19. After initial stabilization through restrictive fluid management, hemadsorption using Cytosorb® was performed and finally temporary extubation of the patient was possible. However, the patient again clinically deteriorated and needed ventilation and finally veno-venous (VV) extracorporeal membrane oxygenator (ECMO) -support and high catecholamine application. Whilst being on VV-ECMO, hemadsorption using Biosky® filter was performed. In this manuscript, after a brief overview of the role of hemadsorption in ARDS, a detailed case presentation is followed by a critical discussion of the current literature.
