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 | Etomidate | Patients randomized to this group will receive etomidate immediately prior to emergency endotracheal intubation.~Etomidate: Patients randomized to this group will receive etomidate immediately prior to emergency endotracheal intubation.~Emergency Endotracheal Intubation: Patients enrolled in the study will be endotracheally intubated. (A breathing tube will be placed into the patient's mouth and trachea). This procedure is being done as part of standard emergency care. Standard endotracheal tubes will be used. Our hospital uses primarily Mallinckrodt (TM) brand endotracheal tubes.~Mechanical Ventilation: Patients enrolled in the study will be mechanically ventilated, using a standard ventilator used in our hospital. The mechanical ventilator is attached to the patient's endotracheal tube and helps sustain the patient's life. Our hospital uses several brands of mechanical ventilators. | 254 | 396 | OG000 |
| Group 2 | Ketamine | Patients randomized to this group will receive ketamine immediately prior to emergency endotracheal intubation.~Ketamine: Patients randomized to this group will receive ketamine immediately prior to emergency endotracheal intubation.~Emergency Endotracheal Intubation: Patients enrolled in the study will be endotracheally intubated.
