Volume Dilution of Sodium Thiocyanate as a Measure of Extracellular Fluid Volume in the Horse

Abstract

SUMMARY Volume dilution of sodium thiocyanate as a measure of extracellular fluid volume was determined in 24 normal adult horses and 4 ponies. The method employed yielded highly reproducible results on multiple determinations in individual horses. A highly significant ( P < .001) correlation between thiocyanate space and body weight was demonstrated.
