Does use of a bougie improve first-attempt emergency intubation success in difficult airway patients?

BEEM Bottom Line

Why is this study important?

Many emergency department (ED) patients requiring endotracheal intubation have anatomic features that indicate a possibly difficult airway. The optimal intubating strategy for these patients is not known. This study compares a strategy of bougie facilitated intubation-to-intubation with the standard endotracheal tube and stylet.

Which, if any, threats to validity are most likely to have an impact on the results and how?
