Bench-to-bedside review: early tracheostomy in critically ill trauma patients

A significant proportion of trauma patients require tracheostomy during intensive care unit stay. The timing of this procedure remains a subject of debate. The decision for tracheostomy should take into consideration the risks and benefits of prolonged endotracheal intubation versus tracheostomy. Timing of tracheostomy is also influenced by the indications for the procedure, which include relief of upper airway obstruction, airway access in patients with cervical spine injury, management of retained airway secretions, maintenance of patent airway and airway access for prolonged mechanical ventilation. This review summarizes the potential advantages of tracheostomy versus endotracheal intubation, the different indications for tracheostomy in trauma patients and studies examining early versus late tracheostomy. It also reviews the predictors of prolonged mechanical ventilation, which may guide the decision regarding the timing of tracheostomy.
