Abstract: Veno-venous extracorporeal membrane oxygenation (V-V ECMO) is used to sustain blood oxygenation and decarboxylation in severe acute respiratory distress syndrome (ARDS). It is under debate if V-V ECMO is as appropriate for coronavirus disease 2019 (Covid-19) ARDS as it is for influenza. In this retrospective study, we analyzed all patients with confirmed SARS-CoV-2 or influenza A/B infection, ARDS and V-V ECMO, treated at our medical intensive care unit (ICU) between October 2010 and June 2020. Baseline and procedural characteristics as well as survival 30 days after ECMO cannulation were analyzed. A total of 62 V-V ECMO patients were included (15 with Covid-19 and 47 with influenza). Both groups had similar baseline characteristics at cannulation. Thirty days after ECMO cannulation, 13.3% of all patients with Covid-19 were discharged alive from our ICU compared to 44.7% with influenza (P = .03). Patients with Covid-19 had fewer ECMO-free days (0 (0-9.7) days vs. 13.2 (0-22.1) days; P = .05). Cumulative incidences of 30-day-survival showed no significant differences (48.6% in Covid-19 patients, 63.7% in influenza patients; P = .23). ICU treatment duration was significantly longer in ARDS patients with V-V ECMO for Covid-19 compared to influenza. Thirty-day mortality was higher in Covid-19, but not significant

Abstract: Background and aim: Liver cirrhosis in patients treated in the intensive care unit (ICU) is associated with high mortality. Well established scores are useful to allow for assessment of prognosis and support ICU treatment guidance. However, currently used scoring systems often do not reflect the complexity of critically ill patients. Therefore, we tested the newly developed Freiburg index-of post-TIPS survival (FIPS) score in order to assess its potential role for prognostication of cirrhotic patients in the ICU. Methods: A total of 310 patients with liver cirrhosis treated in the ICU between 2010 and 2021 were enrolled in this retrospective observational study. Prognostic factors for mortality and 28-day mortality were assessed. Moreover, using c indices the prognostic discrimination of different prognostic scores was analyzed. Results: The FIPS score allowed to discriminate patients with high ICU mortality and within 28-days after ICU treatment (ICU mortality: 42.2 vs. 59.9%, p = 0.008 and 28-day mortality: 43.3 vs. 74.1%, p 0.001). However, the FIPS score in its current composition showed no superior prognostic discrimination compared to other established scores. Multivariable analyses identified the FIPS score (HR 1.25 [1.04-1.49], p = 0.015) and lactate at admission (HR 1.07 [1.04-1.09], p 0.001) as significant predictors of ICU mortality. Lactate at admission substantially improved patient risk stratification within each FIPS risk groups.
