I have had a few cases where we kept the patient on dexmedetomidine for the SBT's (and stopped other sedation such as propofol and fentanyl), because the dexmedetomidine helped with the patient's anxiety and allowed him/her to successfully pass the breathing trials and be extubated. In these patients, anxiety was felt to be the major contributing factor to failing earlier SBT's (when not on dexmedetomidine) including on same-day SBT attempts with and without dexmedetomidine. I'm wondering if this is one of the reasons why the dexmedetomidine group had an average of one more ventilator-free day compared to the usual care group.
