Acute respiratory distress syndrome secondary to severe acute respiratory syndrome coronavirus-2 pneumonia or coronavirus disease 2019-related acute respiratory distress syndrome is the primary cause of mortality in coronavirus disease 2019. Some studies have described the concept of "high and low" elastance coronavirus disease 2019-related acute respiratory distress syndrome and proposed individualized management for the acute respiratory distress syndrome, deviating from low tidal volume ventilation. We report simultaneously measured respiratory parameters (static lung compliance, alveolar dead space ventilation, and shunt fraction) in 14 patients with advanced coronavirus disease 2019-related acute respiratory distress syndrome. The results were consistent with typical acute respiratory distress syndrome and did not support the concept of high-type coronavirus disease 2019-related acute respiratory distress syndrome and low-type coronavirus disease 2019-related acute respiratory distress syndrome.

The primary objective was to evaluate ICU mortality at 28 days in patients with severe hypoxemic respiratory failure due to coronavirus disease 2019 infection who received tocilizumab. The secondary objectives were to evaluate ICU-, hospital-, mechanical ventilation-, and vasopressor-free days at day 28 and development of secondary infections.

Practices regarding anticoagulation use in coronavirus disease 2019 focus primarily on its efficacy in the critically ill without a clear understanding of when to begin anticoagulation. We sought to understand the association of preinfection daily oral anticoagulation use and the short-term mortality of patients hospitalized with coronavirus disease 2019. ⋯ In this retrospective cohort study evaluating oral anticoagulant use among patients with coronavirus disease 2019, we found that patients who are on daily oral anticoagulation at the time of infection and throughout their disease course had significantly lower risk of all-cause mortality at 21 days. Validation of these findings should be performed on population-based levels. While research regarding anticoagulation algorithms is ongoing, we believe these results support future randomized control trials to understand the efficacy and risk of the use of early oral anticoagulation.

Liberal fluid strategies in critically ill patients are associated with harm, thought to be due to endothelial and glycocalyx injury. As the restrictive versus liberal fluid therapy for major abdominal surgery trial not only failed to report survival benefit with restrictive fluids but was associated with a higher rate of acute kidney injury, we hypothesized that factors other than endothelial and glycocalyx injury were likely to account for these findings. Consequently, we measured injury biomarkers in a cohort of the restrictive versus liberal fluid therapy for major abdominal surgery trial.
