Study hypothesis
A gum elastic bougie is a semi rigid plastic covered rod which is commonly used to facilitate intubation with an endotracheal tube when difficulty arises as a result of an inadequate view of the larynx with a conventional laryngoscope. This involves 'blindly' placing the bougie in the trachea and guiding a trachael tube over it. Using a flexible fibreoptic bronchoscope has the advantages of allowing continuous visualisation of the airway. This study would compare the two techniques in anaesthetised patients.

Patient information sheet
Condition
Surgery: Tracheal intubation
Intervention
Randomised trial. Randomisation will be achieved by selecting an envelope containing one of the two methods being studied for guiding the tube into the trachea. The patient will be anaesthetised and therefore unaware of which method is used. It will be impossible to blind the operator (ie the person placing the tube into the trachea) or the assistant (another anaesthetist holding the laryngoscope).

Primary outcome measure
Time from visualisation of the vocal chords to passage of the tube into the trachea
Secondary outcome measures
The presence or absence of carbon dioxide in the expired gases as a measure of success or failure to pass the tube into the trachea
