Pressure Support and Positive End Expiratory Pressure During Spontaneous Breathing Trial (SBT-ICU)

Impact of the Combination of Pressure Support and Positive End Expiratory Pressure During Spontaneous Breathing Trial Versus T-piece on the Time to Successful Extubation

The aim of this study is to assess if a bundle associating pressure support and positive end-expiratory pressure during spontaneous breathing trial and detection by T-piece of patients with high-risk of extubation failure can reduce the time to successful extubation in critically ill patients.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Assisted strategy; Ability to be weaned is determined with pressure support and positive end-expiratory pressure.	Procedure: Assisted strategy; Daily spontaneous breathing trial (SBT) with 7 cmH2O pressure support and 5 cmH2O positive end-expiratory pressure are performed to assess weanability. In case of success, a SBT with T-piece is performed to determine if the patients is at high risk of extubation failure. In this case and/or in the presence of risk factors, systematic non-invasive ventilation is applied after extubation.
Active Comparator: Non assisted strategy; Ability to be weaned is determined with T-piece.	Procedure: Non assisted strategy; Daily spontaneous breathing trials (SBT) with T-piece are performed to assess weanability. In the presence of risk factors, systematic non-invasive ventilation is applied after extubation.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Time (hours) to successful extubation	Successful extubation is defined as extubation without retintubation within the 7 following days.	90 days

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Rate of first extubation	percentage (%) of patients with a first successful extubation divided by the total number of patients per group	90 days
Invasive mechanical ventilation duration	time (hours) spent on invasive mechanical ventilation since inclusion	90 days
duration of non-invasive and invasive mechanical ventilation	time (hours) spent on invasive or non mechanical ventilation since inclusion	90 days
ventilator-free days at Day 90	90 minus the number of days spent on invasive mechanical ventilation (days) since inclusion. Zero day is allocated to dead patients.	90 days
Intensive care unit length of stay	time (days) spent in intensive care unit from inclusion until discharge or death	90 days
hospital length of stay	time (days) spent in the hospital from inclusion until discharge or death	90 days
Day 90 mortality	percentage (%) of patients dead at Day 90	90 days
reintubation rate	percentage (%) of the number of patients with any reintubation divided by the number of patients per group	90 days
