Abstract
(1) Blood-sugar rises and blood-pressure falls as ether anæsthesia progresses.—(2) Blood-sugar is high and blood-pressure low when symptoms of shock are present.—(3) There is some justification for thinking that the pancreatic hormone is deficient as the result of the ketosis produced in connection with ether anæsthesia.—(4) Insulin administration is a successful method of treatment for post-anæsthetic toxic symptoms, which are always associated with a high blood-sugar, and also prevents these from developing. It tends to increase a fallen blood-pressure and reduce a raised blood-sugar during ether anæsthesia.
