Over half of the nearly two million healthcare-associated infections can be attributed to indwelling medical devices. In this review, we highlight the difficulty in diagnosing implantable device-related infection and how this leads to a likely underestimate of the prevalence. We then provide a length-scale conceptualization of device-related infection pathogenesis. ⋯ Using this framework, we describe how current and developing preventative strategies target specific processes along the entire length-scale. In light of the significant time horizon for the development and translation of new preventative technologies, we also emphasize the need for parallel development of in situ treatment strategies. Specific examples of both preventative and treatment strategies and how they align with the length-scale conceptualization are described.

Increased microcirculatory flow and perfusion has been reported to improve clinical outcomes following shock. The optimal resuscitation fluid to restore the flow dynamics of the microcirculation is unknown. This review summarizes the preclinical literature to inform the direction and most important hypotheses for future clinical interventional studies. ⋯ The ideal resuscitation fluid for restoration of the microcirculation following haemorrhagic shock is likely to contain a preparation of haemoglobin, favor higher oncotic potential, and viscosity, protect and reconstitute the endothelium, and attenuate inflammation. These hypotheses that are derived from preclinical research warrant further exploration in the clinical context.
