Historical information

Kelene is the proprietary name used for ethyl chloride in France which became synonymous with the agent in Europe. The manufacturer, Gilliard P. Monnet and Cartier of Lyon, also supplied Redard with his ampoules in 1890.

Ethyl chloride was discovered by the French chemist Guillaume-Francois Rouelle in 1759; however it was not until 1901 that Frederic-Henri Basse manufactured sufficient for scientific study. Marie Jean-Pierre Flourens, Professor Comparative Anatomy at the University of Paris, first reported the effect of the inhalation of ethyl chloride after some experiments with and other agents in dogs. He described three experiments in which the dogs died, however death followed a period of insensibility as with ether although of much faster onset.
