Tracheostomy: update on why, when and how.

PURPOSE OF REVIEW: The aim of this review is to summarize available data, including the most recent ones, to help develop the best possible strategy regarding the use of tracheostomy in ICU patients requiring prolonged mechanical ventilation or who experience loss of airway-protecting mechanisms.

RECENT FINDINGS: Tracheostomy facilitates the weaning process by reducing the patient's work of breathing and increasing comfort. It thus allows for a reduction in sedation levels. It also helps with secretions clearance, facilitates disconnection from the ventilator, and enables earlier phonation, oral intake, and mobilization. Despite these advantages, tracheostomy does not reduce mortality and is associated with both early and late complications, particularly tracheal stenosis. The timing of tracheostomy remains a subject of debate, and only a personalized approach that considers each patient's specific characteristics can help find the best possible compromise between avoiding unnecessary delays and minimizing the risks of performing a needless invasive procedure. In the absence of contraindications, the percutaneous single dilator technique under fibroscopic guidance should be the first choice, but only if the team is properly trained.

SUMMARY: A step-by-step individualized approach based on the available evidence allows identifying the best strategy regarding the use of tracheostomy in ICU patients.
