Insufflation Anaesthesia and the Kelly-Mott Machine

Insufflation Anaesthesia and the Shipway Apparatus

“…These experiments led Meltzer and Auer to their experiments in dogs and rabbits, using a tracheal tube of smaller diameter than the trachea so the air stream was able to exit around the tube and via the trachea, nose and mouth 2,5 . They also used curare to paralyse the animals and physostigmine to reverse the curarisation 3 .…”

“…Other similar devices were developed, including the Kelly-Mott machine 5 . Although the air stream was passed through a humidifying bottle (sometimes heated), the warming effect was probably limited by the high air flows used (up to 30 l/minute) and patients invariably became hypothermic during long operations 3 .…”
