Study hypothesis
Does the laryngeal mask airway (LMA) have a superior efficacy in achieving manual ventilation (breathing) compared with the current recommended technique for children who are not breathing, when used by critical care and anaesthetic nurses?
Ethics approval

Patient information sheet
Condition
Children undergoing ASA I or II surgery or an MRI scan
Intervention
Insertion of a LMA airway versus oropharyngeal airway. Patients have both airways inserted, however the order of the insertion is randomised, immediately prior to inserting the airway, the nurse opens a sealed opaque envelope generated using a table of random numbers which states which airway should be inserted first.
