A comparison of the laryngeal mask airway (LMA) with the facemask and oropharyngeal airway for manual ventilation by PAediatric Ward nurseS in children
ISRCTN ISRCTN38888037
ClinicalTrials.gov identifier
Public title A comparison of the laryngeal mask airway (LMA) with the facemask and oropharyngeal airway for manual ventilation by PAediatric Ward nurseS in children
Scientific title
Acronym PAWS 2
Serial number at source Sponsor ref: 5339
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).
Study design An interventional un-blinded, randomised single centre study.
Countries of recruitment United Kingdom
Disease/condition/study domain Manual ventilation
Participants - inclusion criteria 1. All children aged 6 months to 8 years, scheduled for elective surgery or a magnetic resonance imaging (MRI) scan in which a laryngeal mask airway would be placed routinely
2. Paediatric ward nurses
Participants - exclusion criteria 1. Children in whom a laryngeal mask airway is contradicted, e.g., gastro-oesophageal reflux disease, known difficult airway or obesity
2. Children outside the inclusion age range
Anticipated start date 24/09/2007
Anticipated end date 24/12/2008
Status of trial Completed
Patient information material
Target number of participants 35 nurses, 105 children
Interventions 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 measure(s) 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 measure(s) 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.
