Abstract
Shock was induced in dogs by the release of tourniquets which had been applied to the hind legs for 5 hours. The serum potassium level was followed by spaced sampling. It was seen to rise slightly (from an average of 4.02 mEq/l. to an average of 4.66 mEq/l.) during the prerelease period. Five minutes after the release of the tourniquets, the level had risen to an average of 7.50 mEq/l. and thirty minutes after the release, it had risen to an average of 8.56 mEq/l. At the critical point in the progress of the syndrome (when the mean blood pressure was approximately 50 mm Hg) the average value was 8.46 mEq/l. Ouabain was administered and the level of serum potassium was seen to rise, attaining values as high as 14.67 mEq/l. in one case. The results and significance of these increased levels are briefly discussed as well as an animadversion upon the effects of ouabain on the mean blood pressure.Keywords
