Blood sampled at the end of the exsanguination
by CVP or CT contained additional 0.7%
of intracellular fluid and 16.4% of secondary
blood compared with the first 1.5 ml blood
sample (Exp. B). The width of the 95% confidence
intervals, however, does not exclude the
possibility that contamination by intracellular
fluid was similar at the beginning and at the
end of the exsanguination, nor that the additional
4.4% fluid in CT blood compared with
CVP blood (Exp. A) was represented only by
intracellular fluid or only by secondary blood.
