Frequency of Screening and Spontaneous Breathing Trial Techniques: A Randomized Clinical Trial.
The optimal screening frequency and spontaneous breathing trial (SBT) technique to liberate adults from ventilators are unknown. ⋯ Among critically ill adults who received invasive mechanical ventilation for more than 24 hours, screening frequency (once-daily vs more frequent screening) and SBT technique (pressure-supported vs T-piece SBT) did not change the time to successful extubation. However, an unexpected and statistically significant interaction was identified; protocolized more frequent screening combined with pressure-supported SBTs increased the time to first successful extubation.
