Abstract Introduction The effect of various airway management strategies such as the timing of tracheostomy on liberation from mechanical ventilation MV is uncertain. We tested the hypothesis that tracheostomy when performed prior to active weaning does not influence the duration of weaning or of MV in comparison with a more selective use of tracheostomy. Patients and methods In this observational prospective cohort study surgical patients requiring 72 hours of MV were followed prospectively. Patients undergoing tracheostomy prior to any active weaning attempts early tracheostomy ET were compared with patients in whom initial weaning attempts were made with the endotracheal tube in place selective tracheostomy ST . Results We compared the duration of weaning the total duration of MV and the frequency of fatigue and pneumonia. Seventy-four patients met inclusion criteria. Twenty-one patients in the ET group were
