A cluster randomised trial of paramedics within one ambulance service in England over a 12-month period, split into groups using either the i-gel or LMA Supreme or usual practice for all patients with non-traumatic adult OHCA. Primary outcome was study feasibility, including recruitment and protocol adherence. Secondary outcomes included survival to hospital discharge and to 90 days. 184 of 535 paramedics consented, with 615 patients recruited. The LMA Supreme arm was suspended following 'adverse incidents'. No differences were reported in secondary outcomes.
