Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Ambu AuraGain LMA 'Registered Trademark'. The Ambu AuraGain will be inserted and after achieving satisfactory ventilation via the supraglottic airway device, fibreopitc-guided tracheal intubation will then commence. A maximum of 2 attempts at intubation will be given. The intubation will be performed by an experienced anaesthetist (>10 years’ since commencement of specialist training) who is familiar with the use of both devices (>10 uses on each device) prior to the study. Assessment of any complications will occur directly post-operatively in recovery by the anaesthetist performing the intubation.

Treatment: Devices
Comparator / control treatment
LMA Fastrach 'Registered Trademark'. The LMA Fastrach will be inserted and after achieving satisfactory ventilation via the supraglottic airway device, fibreopitc-guided tracheal intubation will then commence. A maximum of 2 attempts at intubation will be given. The intubation will be performed by an experienced anaesthetist (>10 years’ since commencement of specialist training) who is familiar with the use of both devices (>10 uses on each device) prior to the study. Assessment of any complications will occur directly post-operatively in recovery by the anaesthetist performing the intubation.
