Comparison of Airway Scope and GlideScope in patients with Cervical Spine Immobilisation

INTERVENTION: A single tracheal intubation using the Airway Scope. The process involves placing a breathing tube in the trachea 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 patients mouth. The Airway Scope is a novel video laryngoscope with a number of design features that suggest its utility in the setting of cervical spine immobilisation. CONDITION: Cervical Spine immobilisation PRIMARY OUTCOME: Intubation Difficulty Scale (IDS) Score Time of intubation SECONDARY OUTCOME: Cormack & Lehane grade Number of intubation attempts Number of optimisation manoeuvres required to aid tracheal intubation Rate of successful placement of the tracheal tube INCLUSION CRITERIA: Patients presenting for elective surgery requiring tracheal intubation Americian Society Anesthesiologists (ASA) physical status 1‐3
