Our approach for out-of-center initiation of extracorporeal membrane oxygenation and subsequent interhospital transport.

Extracorporeal membrane oxygenation (ECMO) initiation at a non-ECMO-capable facility by specialized mobile teams aims for a stabilization prior to center admission, internationally referred to as ECMO retrieval. It is a recommended strategy to avoid primary interhospital transfer of compromised patients with a high risk of life-threatening incidents and potentially death. Deploying the unique skill set of ECMO installation and transportation to an unfamiliar environment, however, adds a further degree of complexity to the demanding fields of both transporting the critically ill and ECMO management itself.

Unexpected Observation of Disorder and Multiple Phase-Transition Pathways in Shock-Compressed Zr.

The response of materials under dynamic compression involves a complex interplay of various deformation mechanisms aimed at relieving shear stresses, yielding a remarkable diversity in material behavior. In this Letter, we utilize femtosecond x-ray diffraction coupled with nanosecond laser compression to reveal an intricate competition between multiple shear-relieving mechanisms within an elemental metal. Our observations in shocked-compressed single-crystal Zr indicate a disorder-mediated shear relaxation at lower pressures.

Incidence of heparin resistance and heparin failure in patients receiving extracorporeal membrane oxygenation: an exploratory retrospective analysis.

Background: Unfractionated heparin (UFH) is used in most centers for extracorporeal membrane oxygenation (ECMO) anticoagulation. When standard doses do not achieve desired target values, heparin resistance is reported, most commonly defined as doses of UFH > 35 000 IU/d.

Objectives: To study the incidence of heparin resistance and its association with thromboembolic complications in patients requiring ECMO support.

Release dynamics of nanodiamonds created by laser-driven shock-compression of polyethylene terephthalate.

Laser-driven dynamic compression experiments of plastic materials have found surprisingly fast formation of nanodiamonds (ND) via X-ray probing. This mechanism is relevant for planetary models, but could also open efficient synthesis routes for tailored NDs. We investigate the release mechanics of compressed NDs by molecular dynamics simulation of the isotropic expansion of finite size diamond from different P-T states.

Comparison of Weaning Strategies in Patients Receiving Venovenous Extracorporeal Membrane Oxygenation: An Exploratory Retrospective Study.

Venovenous extracorporeal membrane oxygenation (VV ECMO) facilitates the reduction of mechanical ventilation (MV) support in acute respiratory failure. Contrary to increasing evidence regarding its initiation, the optimal timing of VV ECMO weaning in interaction with MV weaning is undetermined. In this retrospective study, 47 patients who received VV ECMO between 2013 and 2021 and survived ≥1 day after ECMO cessation were divided according to their MV status before ECMO removal: 28 patients were classified into an "ECMO weaning during assisted MV/spontaneous breathing" group and 19 into an "ECMO weaning during controlled MV" group.
