Physiological measurements during anaesthesia with fluoromar.

TRIFLUORO-ETHYL-VINYL-ETHER (Flutization with Fluoromar, according to the oromar) has been reported (Orth, 1955) to technique of Meek, Hathaway and Orth be a non-irritating, rapid-acting anaes(1937). thetic agent. The lower flammability limit is 4 per cent in oxygen or air (ethyl ether, 2 per cent) and the minimum ignition energy is higher by many fold than that of diethyl ether or divinyl ether at the same concentrations (Moen, 1956). It is obviously desirable to minimize the explosive hazard in operating rooms, so it seemed worth while to investigate some of the Surgical patients were anaesthetized by three different techniques. (1) Open drop technique was used with infants and children. (2) Anaesthesia was induced in patients with thiopentone and maintained using a closed circle absorption system with Fluoromar as the anaesthetic agent throughout the rest of the procedures. (3) Twelve patients were studied using variations in physiological functions that Fluoromar as the only anaesthetic agent, might occur during the use of Fluoromar Control chemical analyses were required, as an anaesthetic agent.
