Influence of Anesthesia on Circulatory Changes in Dogs Subjected to Graded Hemorrhage. ∗

Abstract

Summary and Conclusions

1. Circulatory responses to graded hemorrhage varied significantly with six anesthetic procedures studied. 2. Of the drugs studied with the criteria used, the changes with cyclopropane most nearly approached those observed in animals receiving only local procaine. 3. The effects of anesthetic drugs must be taken into consideration in evaluating experimental shock studies.
