Orthogonal Polarization Spectral (OPS)/Sidestream dark field (SDF) imaging: a new method for the observation of the microcirculation in pediatrics
Microcirculation plays an important role both in physiological and pathophysiological states. Early recognition of changes in microcirculation is crucial for starting early therapeutic intervention and reversing the organ failure. Orthogonal polarization spectral (OPS) and Sidestream dark field imaging (SDF) are relatively new noninvasive methods that allow direct visualisation of the microcirc...
متن کاملOrthogonal polarization spectral imaging.
The microcirculation plays a crucial role in the interaction between blood and tissues both in physiological and pathophysiological states. Despite its critical role in numerous diseases including diabetes, hypertension, sepsis or multiple organ failure, methods for direct visualization and quantitative assessment of human microcirculation at the bedside are limited. Orthogonal polarization spe...
متن کاملSidestream Dark Field Imaging of the Microcirculation to Assess Preeclampsia Microvascular Dysfunction
Background Development of predictive models of preeclampsia has only yielded modest results. We hypothesized that impaired indices of microcirculatory function could be detected using sidestream dark field imaging. The objective of this study was to examine microvascular function in women at high risk for preeclampsia at mid-gestation. Methods Women between 16 and 22 weeks of gestation were s...
متن کاملImprovement of Sidestream Dark Field Imaging with an Image Acquisition Stabilizer
BACKGROUND In the present study we developed, evaluated in volunteers, and clinically validated an image acquisition stabilizer (IAS) for Sidestream Dark Field (SDF) imaging. METHODS The IAS is a stainless steel sterilizable ring which fits around the SDF probe tip. The IAS creates adhesion to the imaged tissue by application of negative pressure. The effects of the IAS on the sublingual micr...
متن کاملIn situ assessment of the renal microcirculation in mechanically ventilated rats using sidestream dark-field imaging.
For microcirculation research there is a need for baseline data and feasibility protocols describing microcirculation of various organs. The aim of our study was to examine the reliability and reproducibility of sidestream dark-field (SDF) imaging within the renal cortical microcirculation in rats. Renal microcirculation was observed using SDF probe placed on the exposed renal surface via the u...
