Clinical Trial Summary

The main objective will be to compare the number of ventilator-free days within the 28 days following the first spontaneous breathing trial between strategies of extubation performing spontaneous breathing trials with T-piece trials or with Pressure-Support trials. To do that, the study director proposed to conduct a prospective multicenter randomized controlled open-label trial comparing these 2 strategies of weaning in patients at high-risk of extubation failure in the Intensive Care Unit. Patients included will be randomized before performing the first spontaneous breathing trial and will be assigned to one of the following two groups according to the weaning strategy: T-piece trial group or Pressure-Support trial group.

Related Conditions & MeSH terms

• Extubation
• Respiratory Aspiration
• Weaning From Mechanical Ventilation

Intervention

Procedure:
• T-piece trial
T-piece trial will be performed for around 1 hour with a T-piece connected to the extremity of the endotracheal tube by simply disconnecting the patient from the ventilator and by providing additional oxygen (= 6 L/min)
• Pressure-support trial
Pressure-Support trial will be performed for around 1 hour without disconnecting the patient from the ventilator, by using a low level of pressure-support (PS 8 cm H2O) with a FiO2 = 40% and without positive end-expiratory pressure (PEEP), while continuously monitoring the respiratory rate and tidal volume on the ventilator display.
