Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
ProSeal (TM) laryngeal mask airway.
The airway device will be inserted once the patient is anaesthetised, using a "railroad" technique over a bougie placed in the oesophagus by laryngoscopy.
The cuff will be inflated and the pressure adjusted to 60 cmH20 using a hand pressure gauge.
The airway device will remain in place for the duration of the surgical procedure. The device will be removed from the airway immediately prior to emergence from general anaesthesia.
Intervention code [1] 269299 0
Treatment: Devices
Comparator / control treatment
Standard Mallinckrodt endo-tracheal tube.
Following the induction of general anaesthesia, the patient will have a laryngoscopy performed, and then a standard size 7mm endotracheal tube will be inserted into the trachea. The cuff will be inflated and the pressure checked at 20 cmH20 using a hand pressure gauge.
The airway device will remain in place for the duration of the surgical procedure. The device will be removed from the airway immediately prior to emergence from general anaesthesia.
Control group
Active

Outcomes
Primary outcome [1] 279535 0
Post-operative pain
A verbal analogue scale (VAS) pain score will be recorded.
A quantitative assessment will be made of the consumption of analgesics prescribed on an as needed basis (prn) - morphine in the first two hours and oxycodone thereafter.
Timepoint [1] 279535 0
2 hours and 24 hours post-operatively
