Objective:

To evaluate the necessity of bronchoscopic guidance in percutaneous dilatational tracheostomy (PDT) procedures.

Approach:

Key Findings:

• Bronchoscopic guidance did not reduce major complications or mortality but increased procedural duration.
• Ultrasound can visualize the pretracheal plane, which is crucial for safe needle advancement.
• A combined approach using both ultrasound and bronchoscopy may address procedural risks and complications.

Interpretation:

The authors suggest that a combined guidance strategy may provide better safety outcomes than using either modality alone.

Limitations:

• The trial by Nachshon et al. may not be representative of broader clinical practice due to its high-volume center context.
• Current evidence on bronchoscopic guidance is limited by low event rates.

Conclusion:

Future multicenter trials should compare the safety of single-modality guidance with a combined strategy.
