Tracheostomy Timing in Unselected Critically Ill Patients with Prolonged Intubation: A Prospective Cohort Study

Abstract

Background: Tracheostomy procedures are performed in the intensive care unit (ICU) for prolonged intubation, unsuccessful weaning and infection prevention through either percutaneous or surgical techniques. This study aimed to outline the impact of tracheostomy timing in the ICU on mortality, need for mechanical ventilation, and complications. Methods: Patients were included in the study on the day of tracheostomy. Demographic information, tracheostomy timing, technique, complications, sedation requirement and need for mechanical ventilation at discharge were recorded by an anesthesiologist, including the pre-tracheostomy period. Results: Tracheostomy was performed on 33 patients during the first 14 days of intubation and on 54 patients on the 15th day and beyond. There was no significant difference between the tracheostomy timing and mortality, sedation requirement, or weaning from the ventilator. We observed that patients who underwent tracheostomy with the surgical technique experienced more complications, but there was no significant difference. Tracheostomy performed after the 14th day was shown to be associated with prolonged hospital stay. Conclusions: Early tracheostomy does not have any influence on the need for mechanical ventilation, sedation and mortality. The optimal timing for tracheostomy is still controversial. We are of the opinion that randomized controlled trials involving patient groups with similar survival expectations are needed.
