Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A single tracheal intubation using the Airtraq laryngoscope. The process of intubation involves placing a breathing tube in the 'windpipe' and it occurs after the patient is anaesthetised. The intubation procedure takes less than 2 minutes to complete. Intubation is usually aided by a device called a laryngoscope, which is placed in the patient's mouth. The Airtraq is a novel, single-use optical laryngoscope with a number of design features that suggest its utility in the setting of cervical spine immobilisation.

Comparator / control treatment
A single tracheal intubation using the McCoy laryngoscope. The process of intubation involves placing a breathing tube in the 'windpipe' and it occurs after the patient is anaesthetised. The intubation procedure takes less than 2 minutes to complete. Intubation is usually aided by a device called a laryngoscope, which is placed in the patient's mouth. The McCoy laryngoscope is a standard anaesthetic tool with an established place in the airway management of patients with immobilised cervical spines.
