Suspension laryngoscopy under general anaesthesia. A technique using an injector.
A technique is described of laryngoscopy under general anaesthesia and curarisation using a modification of the Sanders oxygen injection. A plastic catheter is introduced into the trachea through a brass tube fitted on to the laryngoscope blade and oxygen is injected intermittently through the catheter to provide ventilation. Operating conditions are excellent and serial blood-gas measurements on six patients showed that a safe level of Pao2, Paco2 and pH can be maintained.
