AbstractThere has been a significant surge in admissions to critical care during the coronavirus disease 2019 (COVID-19) pandemic. At present, the demands on blood components have not been described. We reviewed their use during the first 6 weeks of the outbreak from 3 March 2020 in a tertiary-level critical care department providing venovenous extracorporeal membrane oxygenation (vv-ECMO). A total of 265 patients were reviewed, with 235 not requiring ECMO and 30 requiring vv-ECMO. In total, 50 patients required blood components during their critical care admission. Red cell concentrates were the most frequently transfused component in COVID-19-infected patients with higher rates of use during vv-ECMO. The use of fresh frozen plasma, cryoprecipitate and platelet transfusions was low in a period prior to the use of convalescent plasma.© 2020 British Society for Haematology and John Wiley & Sons Ltd.
