Pollution Control in the Operating Room: A Simple Device for the Removal of Expired Anaesthesia Vapours

HAROLD CAMERON M.B., CH.B., C.R.C.P.(C)1

1 Department of Anaesthesia, University of Western Ontario and Westminster Hospital, London, Ontario

A modification of the Bird Mark II gas balance valve is described for the purpose of controlling the pollution of the operating room by the fumes of volatile anaesthetic agents. This modification can be carried out by any good machine shop. The valve is adaptable to all anaesthetic machines and is easily dismantled for cleaning and sterilizing. In regular use it has completely eliminated the odour of halothane and methoxyflurane in the operating room and for that reason it has been nicknamed the "stink valve" by the staff. Its use has resulted in a subjective improvement in the symptoms experienced by the author.
