During the COVID-19 pandemic, authorities set up lockdown measures and infection-prevention strategies to avoid an overburdened health-care system. In cases of situational overload of ICU resources, when transporting options are exhausted, the question of a tertiary triage of patients arises.</p><p><strong>Methods: </strong>We provide data-driven analyses of score- and non-score-based tertiary triage policies using simulation and real-world electronic health record data in a COVID-19 setting. Ten different triage policies, for example, based on the Simplified Acute Physiology Score (SAPS II), are compared based on the resulting mortality in the ICU and inferential statistics.</p><p><strong>Results: </strong>Our study shows that score-based tertiary triage policies outperform non-score-based tertiary triage policies including compliance with the German Triage Act. Based on our simulation model, a SAPS II score-based tertiary triage policy reduces mortality in the ICU by up to 18 percentage points. The longer the queue of critical care patients waiting for ICU treatment and the larger the maximum number of patients subject to tertiary triage, the greater the effect on the reduction of mortality in the ICU.</p><p><strong>Conclusion: </strong>A SAPS II score-based tertiary triage policy was superior in our simulation model.

In acute respiratory distress syndrome (ARDS), ECCO₂R has been used to reduce tidal volume, plateau pressure, and driving pressure (\"ultraprotective ventilation\"). Despite achieving these goals, no benefits in outcome could be shown. Thus, in ARDS, the use of ECCO₂R to achieve ultraprotective ventilation can no longer be recommended. Furthermore, ECCO₂R has also been used to avoid intubation or facilitate weaning in obstructive lung failure as well as to avoid mechanical ventilation in patients during bridging to lung transplantation. Although these goals can be achieved in many patients, the effects on outcome still remain unclear due to lack of evidence. Despite involving less blood flow, smaller cannulas, and smaller gas exchange membranes compared with extracorporeal membrane oxygenation, ECCO₂R bears a comparable risk of complications, especially bleeding. Trials to define indications and analyze the risk-benefit balance are needed prior to implementation of ECCO₂R as a standard therapy.

So far, ECPR is not the standard of care but has become part of clinical routine for select patients in many places. As ECPR is a highly invasive support option associated with considerable risks for fatal complications, premature use in patients who may have return of spontaneous circulation should be avoided. However, the selection criteria for ECPR are still evolving, as the search for evidence is ongoing. Recent randomized controlled trials of different ECPR strategies support its use within integrated systems built around highly specialized ECPR centers. The ECPR caseload is an important predictor of patient survival, and continuous training is key for evidence-based quality of care. Typical complications after ECPR include vascular injury or malposition of cannulas, thrombotic complications, hemolysis, and bleeding events that require early detection and interdisciplinary management.

Unfractionated heparin is still the anticoagulant of choice in most centers due to longstanding familiarity with the agent. Disadvantages include alterations in drug responses due to its capability to bind multiple heparin-binding proteins that compete with antithrombin and the potential for heparin-induced thrombocytopenia. In such cases, direct thrombin inhibitors are the treatment of choice but pose difficulties in monitoring due to the limited experience and target ranges for non-aPTT-guided management (aPTT: activated partial thromboplastin time). The current trend toward low-dose anticoagulation, especially for venovenous ECMO, is supported by data associating bleeding complications with mortality but not thromboembolic events, which include circuit thrombosis. However, only prospective data will provide appropriate answers to how to individualize anticoagulation, transfusions, and bleeding management which is currently only supported by expert opinion. Empiric therapy for ECMO patients based on laboratory coagulation alone should always be critically questioned. In summary, only collaboration and future studies of coagulation management during ECMO will help us to make this life-saving therapy that has become part of daily life of the intensivist even safer and more effective. Until then, a fundamental understanding of coagulation and bleeding management, as well as pearls and pitfalls of monitoring, is essential to optimize anticoagulation during ECMO.
