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. | 361 | 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. | 420 | 1,505 | OG001 |

Outcome
- Type
- SECONDARY
- Title
- Return of Spontaneous Circulation (ROSC)
- Description
- Presence of palpable pulses on Emergency Department arrival. Patients pronounced dead in the field coded as ROSC=\[none\].
- Time frame
Patients will be followed from the time of the CA until death or ROSC whichever occurs first. The time frame for this secondary outcome may vary from minutes to hours, but is not expected to last longer than 12 hours.
