Perfusion During Open-Heart Surgery
PERFUSION DURING OPEN-HEART SURGERY Since the description of the Azygos factor by Andreasen and Watson in 1951, perfusion criteria have been much debated. Early investigators fluctuated between a high and low flow rates and the debate continues today. 2 · 3 ' •· 5 '" Hypothermia has been both widely acclaimed and generally repudiated. 7 • 8 Anoxic arrest of the heart' 0 ' n. z, 12 versus corona...
متن کاملDonor Heart Preservation and Perfusion
Due to its technically simple and easily reproducible nature cold static preservation is still the current gold standard for myocardial protection in between donor explantation and recipient implantation. It allows “safe” overall ischemic periods of up to 4 hours with a primary graft failure rate less than 2%. Additional measures such as second rinsing or leucocyte depleted in-situ reperfusion ...
متن کاملPrognostic value of formulas estimating excretory renal function in the elderly with systolic heart failure.
BACKGROUND reduced renal excretory function (REF) is increasingly being appreciated as a potent prognostic factor in chronic heart failure (CHF). The Cockroft-Gault (CG) and the simplified Modification of Diet in Renal Disease (MDRD) equations have been recommended to estimate REF. However, limitations for both formulas have been reported in the elderly. Their prognostic performance in older CH...
متن کاملMyocardial perfusion characteristics during machine perfusion for heart transplantation.
BACKGROUND Optimal parameters for machine perfusion preservation of hearts prior to transplantation have not been determined. We sought to define regional myocardial perfusion characteristics of a machine perfusion device over a range of conditions in a large animal model. METHODS Dog hearts were connected to a perfusion device (LifeCradle, Organ Transport Systems, Inc, Frisco, TX) and cold p...
متن کاملA novel isolated dual perfusion/superfusion heart model for physiological and pharmacological evaluation of mammalian heart preparations
Abstract Introduction: Isolated perfused heart models such as perfusion and superfusion are commonly used for mammalian heart research. However, there are several fundamental limitations in the current techniques. In perfusion model, a suitable cannula is connected to the aorta and the perfusion is retrogradely performed. But, electrode displacement is a potential unwanted event resulted fr...
