Effects of Pectin and Saline Solutions on Survival Time of Dogs in Hemorrhagic Hypotension. ∗ †

Summary

Results on 50 dogs submitted to variable periods of 50 mm Hg. post-hemorrhagic hypotension confirm the conclusions of Middleton and Wiggers 1 that infusions of pectin solutions do not materially increase the chance of recovery unless they are given during an interval which does not exceed 30 minutes of such hypotension. They extend these observations in showing that these beneficial effects are certainly no better than those achieved by administration of simple saline solutions. Finally, they once more stress the fact that the latter are not wholly useless provided they are administered before deleterious effects of prolonged hypotension become operative.
