Ultrasonography for the Confirmation of Endotracheal Tube Intubation: A Systematic Review and Meta-Analysis.

Intubation is routinely performed in the emergency department, and rapid, accurate confirmation is essential to avoid potentially serious adverse outcomes. The number of studies assessing ultrasonography for the verification of endotracheal tube placement has expanded rapidly in recent years. We performed this systematic review and meta-analysis to determine the sensitivity and specificity of transtracheal ultrasonography for the verification of endotracheal tube location.
