Adjusted hypervolemic hemodilution in acute ischemic stroke.
We prospectively randomized 47 patients with acute ischemic stroke of the middle cerebral artery of less than 24 hours' duration to either adjusted hypervolemic hemodilution or control treatment and followed them up for 90 days. Rapid hemodilution to a target hematocrit of 30-35% as monitored with bedside determinations was achieved by using infusions of dextran 40, venesections, and infusions ...
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...
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 کاملHypervolemic hemodilution in acute ischemic stroke: the Multicenter Austrian Hemodilution Stroke Trial (MAHST).
BACKGROUND AND PURPOSE Experimental studies suggest a beneficial effect of hemodilution on acute ischemic stroke. This was not proven by previous multicenter trials in the clinical setting. Various reasons have been suggested for the failure of these studies, which we attempted to consider in the Multicenter Austrian Hemodilution Stroke Trial (MAHST). METHODS MAHST is a randomized, double-bli...
