Scientific title	Randomised comparison of the effectiveness of the Laryngeal Mask Airway Supreme, i-gel and current practice in the initial airway management of pre-hospital cardiac arrest: a feasibility study (REVIVE-Airways)
Study acronym	REVIVE
Study objectives	Cardiac arrest occurs when the heart suddenly stops beating, and is one of the most extreme medical emergencies. Outcomes remain poor with most patients not surviving. Effective treatments for cardiac arrest are limited and represent a major unmet health need. The main treatment is cardiopulmonary resuscitation (CPR), which is a combination of rescue breathing and chest compressions. Prompt and effective CPR is essential to prevent damage to the brain and other organs. Minimising interruptions of continuous chest compressions improves survival. Current evidence supports a change in rescue breathing. Historically, placing a breathing tube in the windpipe (tracheal intubation) was viewed as the best pre-hospital airway management in cardiac arrest, but we now know that attempting intubation can lead to significant complications and prolonged interruptions in chest compressions. As a result, national recommendations advocate using newer airway devices (supraglottic airway devices: SADs). These are quicker to insert and cause minimal interruption to chest compressions. However the best type of SAD and their effectiveness in comparison to current practice is unknown. This research study is a preliminary investigation to determine whether our proposed design will allow us to compare the two most promising SADs (i-gel and LMAS) with current practice during pre-hospital cardiac arrest. This will be done by dividing paramedics working in Great Western Ambulance Service, and who agree to take part, into three groups. Each group will be given structured education on CPR and rescue breathing. One group will be taught to use the i-gel, one group the LMAS and one group will continue as usual. If this research design works, and produces useful results, we will proceed to a large scale study to determine whether one of these approaches improves patient survival. This will shape future guidelines and benefit cardiac arrest patients in the UK and internationally. More details can be found at http://public.ukcrn.org.uk/Search/StudyDetail.aspx?StudyID=11962
Ethics approval(s)	First MREC 31/10/2011 ref: 11/EE/0407
Health condition(s) or problem(s) studied	Injuries and Emergencies
Intervention	i-gel Arm, Patients attended by a paramedic who has been randomised to this arm will receive resuscitation according to the Resuscitation Council (UK) and JRCALC Advanced Life Support Guidelines, with the exception that the i-gel supra-glottic airway device will be used initially to manage the airway. All standard advanced life support interventions will be provided including drug administration, defibrillation and chest compressions as required.; LMAS Arm, Patients attended by a paramedic who has been randomised to this arm will receive resuscitation according to the Resuscitation Council (UK) and JRCALC Advanced Life Support Guidelines, with the exception that the Laryngeal Mask Airway Supreme (LMAS) supra-glottic airway device will be used initially to manage the airway. All standard advanced life support interventions will be provided including drug administration, defibrillation and chest compressions as required. Usual Practice Arm, Patients attended by a paramedic who has been randomised to this arm will receive resuscitation according to the Resuscitation Council (UK) and JRCALC Advanced Life Support Guidelines. All standard advanced life support interventions will be provided including drug administration, defibrillation and chest compressions as required.; Follow Up Length: 3 month(s)
Intervention type	Other
Primary outcome measure	Assess if it is possible to conduct a full-scale study
Secondary outcome measures	No secondary outcome measures

Eligibility

Participant type(s)	Patient
Age group	Adult
Lower age limit	18 Years
Sex	All
Target number of participants	Planned Sample Size: 534; UK Sample Size: 534; Description: The sample size of 534 comprises 150 paramedics and 384 patients
Key inclusion criteria	Paramedics: Working in Great Western Ambulance Service and consenting to participate Patients: 1. Have had a cardiac arrest in the pre-hospital setting 2. Attempted resuscitation is appropriate according to standard guidelines 3. Aged 18 years or older 4. Target Gender: Male & Female
Key exclusion criteria	Patients: 1. Less than 18 years old 2. Estimated weight is less than 50 kg 3. Mouth opening is less than 2 cm 4. The latter two exclusions have been applied because the SGAs evaluated in this trial are not designed for use in patients with low body weight or significantly reduced mouth opening.
