AB - COVER NOTE Marrett conducted a series of experiments with the apparatus using halothane in a closed circuit. “Consumption varied between 4 ml and 6 ml per hour. Considering the high price of halothane, this is very economical compared with the open- and semi-open administration.” The vaporizer was not calibrated and, in order to ascer- tain the relative strength of halothane, Marrett undertook what he referred to as a “personal trial. It is not clear from the article whether he actually inhaled the vapour himself but he reported that “with the control set at three fourths of the first division, no irritant effect was noticed; nor the buzzing in the head so characteristics of nitrous oxide and other inhalational anaes- thetics.” He went on to administer with the stopcock fully on to the closed circuit and reported “loss of consciousness in one minute, with ten minutes for recovery and again, no headache or nausea. It was therefore clear that the concen- tration was safe and that halothane was likely to be most Dr H. Rex Marrett of St Bartholomew’s Hospital first useful for inductions.” described his simple drawover vaporizer system in the He reported over 1550 halothane anaesthetics with the
