ABSTRACT
In late 2020, during the second wave of COVID-19 in Germany, we started using the MobyBox, which is a novel fully pneumatically driven ECMO device, on a regular basis to meet the increasing demand for ECMO therapy. In this case series, we performed a retrospective chart review of seven patients with severe COVID-19-related acute respiratory distress syndrome (ARDS) requiring veno-venous (vv)-ECMO support with the MobyBox. During ECMO treatments we have observed no disadvantages in comparison to conventional ECMO systems. There were no system failures or adverse events directly attributable to the MobyBox system. Our data support that providing vv-ECMO with the MobyBox device is safe and feasible. Furthermore, our findings suggest that the MobyBox device might represent an advantage in terms of biocompatibility. Therefore, more data on this issue is needed to better understand how the pneumatically driven pump affects cellular blood components.

OBJECTIVES: Cardiac surgery training has become more challenging as patients and their diagnoses become more complex. Our goal was to develop a multicategorical assessment model for evaluating residents in cardiac surgery. This model is intended to ensure goal-directed progress in their training as well as to recognize and support their surgical talents. METHODS: We developed a new questionnaire in a multistage, 3-round process based on the Delphi method 'estimate-talk-estimate', using 55 competencies, including 38 general and 17 domain-specific competencies. Each competency is evaluated with 1 or more questions, to which 1 (not competent) to 6 (very competent) points can be chosen as an answer. RESULTS: The resulting model achieved 2 main goals: first, presenting a well-defined competency list for cardiac surgical training and second, providing an objective and realistic evaluation of trainees' abilities. Residents were assessed by all trainers to achieve a high level of objectivity. CONCLUSIONS: This evaluation model is highly objective, because residents are evaluated by multiple trainers. It allows individual support and enables better transparency in residency training. Talents and skills are evaluated, recognized and adopted as a base for individual feedback and personalized training programmes.
