简要总结
This randomized controlled open label trial aims at comparing a weaning strategy including a spontaneous breathing trial as a prerequisite for extubation to a weaning strategy without a spontaneous breathing trial (direct extubation) in patients with readiness to be weaned criteria and considered at low risk of extubation failure. The main endpoint will be the proportion of patients successfully extubated within the 24 hours after randomization as compared to extubation after a successful spontaneous breathing trial (SBT).
详细描述
Weaning from mechanical ventilation is a critical step in the course on an ICU stay. Separation from the ventilator should be done at the earliest possible time, but extubation failure is an adverse event that should be avoided. The most common decision-making strategy regarding weaning and extubation is to combine a daily assessment of the patient's "readiness to wean" and a spontaneous breathing trial before to extubate.
The result of the SBT (passed of failed) is often viewed as a "go - no go" indicator of whether or not patients are ready for extubation, but daily practice indicates that the assessment of the SBT is subjective with a frequent natural tendency for clinicians to keep their patients on the 'safe' side, i.e., considering them as not being ready for extubation. However, the results of the SBT should be interpreted based on the pre-test probability. Conducting a SBT in patients while the pre-test probability of success is high will result in false negatives which are likely to delay the decision of extubation. In addition, a pointless SBT may expose patients to anxiety, air hunger and dyspnea which are poorly detected by caregivers. The hypothesis of the present project is that in patients who are at low risk of extubation failure, a SBT is useless and once readiness to wean criteria are met, direct extubation would increase the proportion of patients successfully extubated within the 24 hours after randomization as compared to extubation after a successful SBT.
