Comparison of three point-of-care ultrasound techniques to confirm endotracheal tube placement: A randomized clinical trial

This study aimed to compare the diagnostic performance and speed of three point-of-care ultrasound techniques—transtracheal ultrasound (TUS), lung-sliding ultrasound (LUS), and diaphragm ultrasound (DUS)—for confirming endotracheal tube placement after emergency intubation. The results showed that all three techniques had high accuracy in detecting tracheal placement, but TUS was the fastest method for confirmation. The findings suggest that TUS may be the preferred ultrasound technique in emergency settings for rapid verification of endotracheal tube position.
