Study hypothesis
Does the laryngeal mask airway (LMA) have a superior efficacy to achieve manual ventilation compared with the current recommended technique (the oro-pharyngeal airway and face mask) for children who are not breathing when used by paediatric ward nurses?
Please note that this trial is a follow-on from the previously registered trial ISRCTN38042170 - A comparison of the laryngeal mask airway with the oropharyngeal airway and facemask to achieve manual ventilation in children as performed by critical care and anaesthetic nurses (see http://www.controlled-trials.com/ISRCTN38042170), which investigates the LMA used by critical care and anaesthetic nurses.
Ethics approval
Ethics approval received from the Oxfordshire Research Ethics Committee A on the 10th Septermber 2007 (ref: 07/H0604/76).

Condition
Manual ventilation
Intervention
The child would be anaesthetised in a standard way by a consultant anaesthetist. Once asleep the paediatric ward nurse would insert each airway device in random order and manually ventilate the lungs for a minimum of five breaths. Ventilation would be measured by an ultrasonic displacement device sited over the chest and compared to that achieved by the consultant paediatric anaesthetist. There is no follow up after the intervention.

Primary outcome measures
Chest expansion (as a percentage of that achieved by the consultant paediatric anaesthetist, averaged over five breaths), measured at the time of the intervention.
Secondary outcome measures
1. To assess the effectiveness of ventilation by paediatric ward nurses when using the facemask and oropharyngeal airway
2. To assess whether the paediatric ward nurses can be trained to successfully place the laryngeal mask airway in anaesthetised children after mannikin training
3. To assess whether a learning curve exists for successful insertion of the laryngeal mask airway
4. To compare the time taken to successful ventilation using both airway devices
All outcomes will be measured at the time of the intervention.
