"Trilene" is the brand name of the drug trichloroethylene, manufactured by Ayerst Laboratories. The chemical formula for trichloroethylene was discovered in 1863, and it became a popular analgesic in the 1940s and 1950s. It provides a light level of unconsciousness, and wears off quickly. It was recommended for analgesia (pain relief) in minor procedures such as the treatment of burns, stitching of wounds, and biopsies.

The Duke University Inhaler was made specifically to vaporize this liquid agent. Trilene, and the Inhaler, were marketed primarily for use with pediatric patients and women in labor.

Advertisements emphasized that it was non-explosive, and that it caused less nausea than did ether. But these advantages were outweighed by its environmental impact, and in 1977 the FDA banned its use as an anesthetic.
