Researchers in the U.S. and England now report two separate, large cluster-randomized trials that compared outcomes when paramedics performed endotracheal intubation versus placed a supraglottic airway device.
In the U.S. trial, 27 emergency medical services (EMS) agencies were randomized in 13 clusters to initial airway management with a supraglottic laryngeal tube (1505 patients) or endotracheal intubation (1499 patients), with crossover to the alternate strategy every few months.
