A Successful Treatment for Toxic Symptoms resulting from Ether Anaesthesia, based on a Biochemical Investigation.

(1) Blood-sugar rises and blood-pressure falls as ether anaesthesia 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 anaesthesia.-(4) Insulin administration is a successful method of treatment for post-anaesthetic 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 anaesthesia.
