THE TOXICITY OF THORACIC DUCT FLUID AFTER RELEASE OF TOURNIQUETS APPLIED TO THE HIND LEGS OF DOGS FOR THE PRODUCTION OF SHOCK

Abstract

The thoracic duct fluid becomes blood-stained after the release of tourniquets applied to the hind legs of dogs. When this fluid is injected intraven. its effect upon blood pressure is variable. The vasodepressor effect is more frequent when large doses of nembutal have been used for narcosis. When narcosis is controlled to avoid vasodepression, inj. of thoracic duct fluid from normal dogs has no significant effect. In contrast, a fall in blood pressure follows in 50% of the animals injected with the thoracic duct fluid of animals shocked by the tourniquet method.
