Blood volume and extracellular fluid volume in anesthesia.
From every day experience we find that the accepted standards and indices for the quantitative adequacy of the circulating blood, such as hemoglobin-gms and hematocrit percents, are not adequate and do not reflect volume or mass. The laboratory tests that we have habitually adopted as guidelines denote percentage concentration per unit volume and not absolute amounts. There is all the differenc...
متن کاملRegulation of extracellular fluid volume and blood pressure by pendrin.
Na(+) is commonly designed as the culprit of salt-sensitive hypertension but several studies suggest that abnormal Cl(-) transport is in fact the triggering mechanism. This review focuses on the regulation of blood pressure (BP) by pendrin, an apical Cl(-)/HCO(3)(-) exchanger which mediates HCO(3)(-) secretion and transcellular Cl(-) transport in type B intercalated cells (B-ICs) of the distal ...
متن کاملModifications of blood volume alter the disposition of markers of blood volume, extracellular fluid, and total body water.
Recirculatory pharmacokinetic models for indocyanine green (ICG), inulin, and antipyrine describe intravascular mixing and tissue distribution after i.v. administration. These models characterized physiologic marker disposition in four awake, splenectomized dogs while they were normovolemic, volume loaded (15% of estimated blood volume added as a starch solution), and mildly and moderately hypo...
متن کاملMechanisms of proximal tubule sodium transport regulation that link extracellular fluid volume and blood pressure.
One-hundred years ago, Starling articulated the interdependence of renal control of circulating blood volume and effective cardiac performance. During the past 25 years, the molecular mechanisms responsible for the interdependence of blood pressure (BP), extracellular fluid volume (ECFV), the renin-angiotensin system (RAS), and sympathetic nervous system (SNS) have begun to be revealed. These v...
متن کاملDetermination of Extracellular Fluid Volume in Healthy and Azotemic Cats
BACKGROUND Methods for determining extracellular fluid volume (ECFV) are important clinically for cats. Bromide dilution has been studied in cats to estimate ECFV. Markers of GFR also distribute in ECFV and can be used for its measurement. HYPOTHESIS/OBJECTIVES The primary objective was to develop a method of determining ECFV from iohexol clearance in cats and evaluate agreement with that det...
