Closed circuit halothane anaesthesia. Use of the Narkotest as an in-line monitor in a nonpolluting technique.
Theoretical considerations of closed circuit anaesthesia using oxygen and halothane are examined. Clinical experience has confirmed the value of the Narcotest as a reliable in-line monitor of inspired halothane concentration, while the use of an oxygen analyser is a desirable adjunct. The advantages of economy and elimination of theatre pollution are discussed.
