Abstract
Properties: Vinyl ether, CH2:CH2:O:CH2:CH2, a volatile liquid. Lipoidsoluble but highly inflammable.
Toxicity.—Has little effect on liver function; overdoses produce respiratory paralysis, but not cardiac paralysis.
Indications.—Replaces ethyl chloride for short operations, and can be added to gas and oxygen instead of ether or chloroform. Is a safe and portable anæsthetic for the general practitioner.
Administration.—Open method convenient, but not very satisfactory, a closed method produces better anæsthesia. Special inhaler described and illustrated.
Vinyl ether is obtainable in ampoules of 3 c.c., a sufficient quantity for the average case.
Induction is rapid; signs of anæsthesia described. Patient's colour remains excellent.
Apparatus required when vinyl ether is to be added to gas-and-oxygen.
