Hands Free Technique: New Tool Possibility for Image Capture of Sublingual Microcirculation with Handheld Vital Microscopy - HVM

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...

Microcirculation changes in gingival tissue after ultrasonic tooth preparation in beagle dogs

J. appl. oral sci; 28 (), 2020
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...

Efeitos da morte cerebral na microvasculatura pulmonar em um modelo experimental de doador de pulmão

J. bras. pneumol; 46 (2), 2020
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...

Association between peripheral perfusion, microcirculation and mortality in sepsis: a systematic review

Rev. bras. anestesiol; 69 (6), 2019
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...

Near-infrared spectroscopy parameters in patients undergoing continuous venovenous hemodiafiltration

Einstein (Säo Paulo); 17 (1), 2019
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 ...

Effect of short-term ischemia on microcirculation and wound healing of adipocutaneous flaps in the rat

Acta cir. bras; 34 (12), 2019
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...

Is the early or delayed remote ischemic preconditioning the more effective from a microcirculatory and histological point of view in a rat model of partial liver ischemia-reperfusion?

Acta cir. bras; 33 (7), 2018
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 ...

Association of Inflammation and Endothelial Dysfunction with Coronary Microvascular Resistance in Patients with Cardiac Syndrome X

Arq. bras. cardiol; 109 (5), 2017
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...

Recentes avanços na avaliação da microcirculação à beira do leito em pacientes graves

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...
