Hexafluorodiethyl Ether (Indoklon) Convulsive Therapy: A Pilot Study

Abstract
In 1957 Krantz, Truitt, Ling and Speers found that the inhalation of small amounts of hexafluorodiethyl ether (Indoklon) produced convulsions in animals, and it was later used as a therapeutic convulsant for the treatment of psychiatric patients (Krantz, Truitt, Speers and Ling, 1957).
