title: Impairment of tracheal ring ciliary activity by halothane.
abstract: The effects of varying concentrations of halothane on tracheal ciliary activity were studied using a ferret tracheal organ culture technique. Using 1% and 2% halothane produced no impairment of ciliary activity, while 3% halothane caused some ciliostasis; 4% and 5% halothane produced rapid cessation of ciliary activity. Recovery was prompt and complete after exposure to 4% halothane for as long as 3 days, but after 4 days of exposure recovery was incomplete and after a week of exposure death of ciliary cells occurred.
