Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older who are undergoing mechanical ventilation and require treatment with a neuromuscular blocker.

Probably not a fit

Patients with acute or chronic neurologic injuries that impair assessment or those who die before extubation will not benefit from this study.

What this trial studies

This trial aims to evaluate the effects of different neuromuscular blockers on patients who are mechanically ventilated in emergency departments. It will involve screening and enrolling eligible patients across five medical centers over three years, using a stepped wedge cluster randomized design. Initially, all sites will provide usual care, followed by a transition to using succinylcholine as the default neuromuscular blocker in a staggered manner. The study will assess the impact of these interventions on patient outcomes, particularly focusing on awareness and complications related to intubation.

Why it matters

Potential benefit: If successful, this study could improve the management of mechanically ventilated patients and reduce complications associated with intubation.

How similar studies have gone: Previous studies have shown varying success with similar approaches, but this specific design and focus on neuromuscular blockers in emergency settings is relatively novel.
