ANAESTHESIA BY THE INTRATRACHEAL INSUFFLATION OF AIR AND ETHER

Ether, Note on the Intratracheal Insufflation of

Changes in respiratory physiology during ether--air anaesthesia.

Measurements of arterial oxygen and carbon dioxide tension, alveolar ventilation, alveolar to arterial oxygen difference, and ratio of deadspace to tidal volume have been made to show the changes induced by ether/air anaesthesia with spontaneous respiration, with mechanical ventilation, and with mechanical overventilation. There was a disproportionate fall in oxygen tension during spontaneous r...

An Experimental Study of the Question of Aspiration of Foreign Material into the Air Passages during Intratracheal Insufflation

The foregoing experiments clearly justify the following conclusions :- Intratracheal insufflation protects the respiratory tract very efficiently against any invasion from the pharynx. The filling up of the pharynx with extraneous material, whether it be from the stomach or from the mouth, brings no danger to the trachea and bronchi. This holds true even if the animal is under deep anesthesia. ...
