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 ECMO-support and high catecholamine application. Whilst being on VV- ECMO, hemadsorption using Biosky® MG 350 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.
A 35-year-old woman was admitted to the hospital with a 2-day history of increasing cough and chest congestion. Two days before admission, the patient noted the onset of sore throat, sinus congestion, and a worsening nonproductive cough. She reported having chills and fever coinciding with the onset of the cough. A review of systems was remarkable only for markedly diminished oral intake during the 48 hours before admission. The patient's medical history was notable for spinal muscular atrophy diagnosed at the age of 6 months and an episode of communityacquired pneumonia 2 years before the current admission. Her only medication was an enema once weekly to facilitate bowel movements, and she had no known drug allergies. Her family history was remarkable for 2 siblings who died in infancy secondary to spinal muscular atrophy. She denied alcohol, tobacco, or illicit drug use. On physical examination, the patient was afebrile, her pulse rate was 117/min, and her blood pressure was 79/43 mm Hg. Respirations were 12/min, and pulse oximetry revealed an oxygen saturation of 99% while the patient breathed room air. Her height and weight were 152.4 cm and 32.4 kg, respectively (body mass index, 14 kg/m 2). The patient appeared thin and had marked muscular atrophy but was in no acute distress. The mucous membranes appeared dry, and heart sounds were normal. Decreased inspiratory effort was noted, and bronchial breath sounds were heard at the base of the left lung. She had absent deep tendon reflexes and diffuse muscular weakness (proximal greater than distal). Findings on the remainder of her examination were unremarkable. Chest radiography revealed a left lower lobe infiltrate. Laboratory test results were as follows (reference ranges shown parenthetically): white blood cell count, 21.4 × 10 9 / L
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.
