title: [The concentrations of halothane in the operating theatre and its dependance on various methods of removal (author's transl)].
abstract: Measurement of halothane concentrations by means of gas chromatography was used to compare the efficiency of 1) a filtration system and 2) ducting of gases into the exhaust of the ventilation system of our operating threatre. The concentrations were found to be lower when the latter method was used. Measurements made subsequently provided data on halothane concentrations occurring during routine service when different methods of anaesthesia were used, with and without ducting of gases into the ventilation exhaust system.
