Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Use of suction enhanced laryngeal mask airway
Insertion is by a consultant anaesthetist at induction of anaesthesia which occurs five minutes prior to surgical start time.
Duration of anaesthesia and use of the suction enhanced laryngeal mask airway will be less then two hours
Removal will be either by the consultant anaesthetist in theatre or a qualified recovery nurse in the stage one post anaesthesia care unit.
Strategies to monitor adherence to the intervention will be review of anaesthetic record and data collection form.


The suction enhanced laryngeal mask airway sits in the same position/location in the airway and functions to ventilate the patient in exactly the same way. It differs from the standard laryngeal mask airway in that suction can be applied to the oropharyngeal surface. Suction applied via the Suction Enhanced Laryngeal Mask Airway will be between 80-200mmHg, which is accepted safe levels of suction applied to airways via other devices such as in line suction catheters down endotracheal tubes.

Efficacy
Statistical methods / analysis
Qualitative pilot study - clinician feedback will be most useful part of data, statistical analysis will be limited to percentage of cases were clinicians deemed effective.
Number of participants was not statistically derived, rather reflects the number of cases the investigators assess the clinicians need to assess efficacy of suction enhanced laryngeal mask airway.
