New microcirculatory imaging techniques allowed direct observation of microcirculation at the bedside. This study presents a new device that assists the operator with the unprecedented Hands Free technique. To this end, a replica of Handheld Vital Microscopy was developed to simulate the method of captur...
Abstract Ultrasonic wave technology is widely used during dental treatments. We previously demonstrated that this method protects the gingival tissue. However, the physiological change on the gingival microvasculature caused by this method remains unclear. Objective The aim of this study was to investi...

RESUMO Objetivo A morte cerebral (MC) desencadeia alterações hemodinâmicas e inflamatórias importantes, comprometendo a viabilidade dos órgãos empregados em transplantes. Para compreender melhor as alterações microcirculatórias nos pulmões de doadores com MC, o presente estudo investigou a mic...
Abstract Although increasing evidence supports the monitoring of peripheral perfusion in septic patients, no systematic review has been undertaken to explore the strength of association between poor perfusion assessed in microcirculation of peripheral tissues and mortality. A search of the most important...
ABSTRACT Objective To investigate the impacts of continuous venovenous hemodiafiltration on the microcirculation in patients with acute kidney injury. Methods A prospective observational pilot study conducted in a 40-bed, open clinical-surgical intensive care unit of a private tertiary care hospital ...
Abstract Purpose Composite flaps used in reconstructive surgery may intra- and postoperatively suffer from hypoperfusion and/or ischemia-reperfusion influencing wound healing. We aimed to follow-up the effect of ischemia on adipocutaneous flaps' wound healing and microcirculation. Methods In anesthet...

Abstract Purpose: To compare early- and late-effect remote ischemic preconditioning (RIPC) by analysing the microcirculatory, hemodynamic and histological changes in partial liver ischemia-reperfusion of rats. Methods: 60-minute partial liver ischemia followed by 120-minute reperfusion was performed ...

Abstract Background: Although a proportion of CSX patients have impaired brachial artery flow-mediated dilatation (FMD) in response to hyperemia, suggesting that endothelial dysfunction in these patients may be systemic and not just confined to the coronary circulation; the underlying mechanisms trigger...
RESUMO Parâmetros relacionados à macrocirculação, como pressão arterial média, pressão venosa central, débito cardíaco e saturação venosa mista e central de oxigênio, são comumente utilizados na avaliação hemodinâmica de pacientes graves. No entanto, diversos estudos demonstram que existe...
