Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Endotracheal Intubation | The insertion of a plastic breathing tube through the mouth and into the trachea.~Endotracheal Intubation: In this traditional model of OHCA airway management, advanced-level Emergency Medical Services (EMS) personnel will use ETI as the primary (initial) airway management intervention. If the EMS agency is assigned to this arm, basic-level EMS personnel will use bag-valve-mask ventilation only even if they would normally use an LT. | 121 | 1,495 | OG000 |
| Group 2 | Laryngeal Tube (King) | Insertion of a supraglottic airway (SGA)~Laryngeal Tube (King): In this test model of OHCA airway management, advanced-level Emergency Medical Services (EMS) personnel will use LT as the primary (initial) airway management intervention. Basic-level EMS personnel will use bag-valve-mask ventilation. If trained to use LT, basic-level EMS personnel may perform LT insertion. | 163 | 1,504 | OG001 |
