cyclopropane

 [si″klo-pro´pān]
a colorless, flammable gas with a characteristic odor and pungent taste that is an inhalational anesthetic; now little used because of its flammability.

cy·clo·pro·pane

(sī'klō-prō'pān),
An explosive gas of characteristic odor; in the past, widely used to produce general anesthesia.
Synonym(s): trimethylene

cyclopropane

/cy·clo·pro·pane/ (-pro´pān) a colorless, highly inflammable and explosive gas, C3H6, used as an inhalation anesthetic.

cyclopropane

cyclopropane

a powerful central nervous system depressant used as an inhalation anesthetic. The drug can be given in small doses and is particularly useful in anesthetizing poor-risk patients. This gas is highly explosive and requires special handling and precautions against sparks or flames, which would result in an explosion. No longer used for safety reasons.
