Meadows YR 2020 UL http://openres.ersjournals.com/content/early/2020/09/17/23120541.00463-2020.abstract AB Rationale The use of veno-venous extracorporeal membrane oxygenation (VV-ECMO) in severe hypoxaemic respiratory failure from Coronavirus disease 2019 (COVID-19) has been described, but reported utilisation and outcomes are variable, and detailed information on patient characteristics is lacking. We aim to report clinical characteristics, management, and outcomes of COVID-19 patients requiring VV-ECMO, admitted over 2 months to a high-volume UK centre.Methods Patient information, including baseline characteristics and clinical parameters, was collected retrospectively from electronic health records for COVID-19 VV-ECMO admissions between 3rd March and 2nd May 2020. Clinical management is described. Data are reported for survivors and non-survivors.Results We describe 43 consecutive patients with COVID-19 who received VV-ECMO. Median age was 46 years [IQR 35.5–52.5], 76.7% were male. Median time from symptom onset to VV-ECMO was 14 days [IQR 11–17.5]. All patients underwent computed tomography imaging, finding extensive pulmonary consolidation in 95.3%, and pulmonary embolus in 27.9%. 79.1% received immunomodulation with methylprednisolone for persistent maladaptive hyperinflammatory state. Vasopressors were used in 86%, and 44.2% received renal replacement therapy. Median duration on VV-ECMO was 13 days [IQR 8–20]. Fourteen patients died (32.6%) and 29 survived (67.4%) to hospital discharge. Non-survivors had significantly higher d-dimer (38.2 versus 9.5 mg·L−1, Fibrinogen Equivalent Units; p=0.035) and creatinine (169 versus 73 umol·L−1; p=0.022) at commencement of ECMO.Conclusions Our data supports the use of VV-ECMO in selected COVID-19 patients. The cohort was characterised by high degree of alveolar consolidation, systemic inflammation, and intravascular thrombosis.FootnotesThis manuscript has recently been accepted for publication in the ERJ Open Research.
