Development, implementation, and evaluation of an institutional daily awakening and spontaneous breathing trial protocol: a quality improvement project.
While one controlled trial found that a daily awakening and spontaneous breathing trial (DA-SBT) decreases time on mechanical ventilation (MV), there is a paucity of real-world data surrounding the development, implementation, and impact of DA-SBT protocols. We describe a multidisciplinary process improvement effort in 2, 10-bed medical intensive care units (MICUs) at a 330-bed academic medical center that focused on the development, implementation, and evaluation of a new DA-SBT protocol. ⋯ Despite the implementation of a DA-SBT protocol that was individualized to clinician preferences and institutional resources and accompanied by substantial education and reminders for use, compliance to the DA component of this protocol was low and duration of MV remained unchanged. Additional quality improvement strategies are needed to overcome barriers to DA-SBT protocol use that may not exist in controlled clinical trials.

Ventilator practices in patients at risk for acute lung injury (ALI) and ARDS are unclear. We examined factors associated with choice of set tidal volumes (VT), and whether VT < 8 mL/kg predicted body weight (PBW) relates to the development of ALI/ARDS. ⋯ Clinicians seem to respond to ALI/ARDS with lower initial VT. Initial VT, however, was not associated with the development of post-intubation ALI/ARDS or other outcomes.

Case ReportsSuccessful management of warfarin-exacerbated diffuse alveolar hemorrhage using an extracorporeal membrane oxygenation.
Although diffuse alveolar hemorrhage complicating warfarin therapy is rare, it generally has a worsening clinical course and can be a life threatening condition. A 56-year-old male who had undergone a pulmonary lobectomy for lung cancer 2 years before had received warfarin for about 5 months due to pulmonary vein thrombosis. The patient presented with severe dyspnea and had prolonged anticoagulation values. ⋯ The reversal of anticoagulation was initiated, and extracorporeal membrane oxygenation was performed for refractory respiratory failure that did not improve despite maximal mechanical ventilatory support. The diffuse alveolar infiltrations resolved after 5 days, and we successfully weaned off both extracorporeal membrane oxygenation and mechanical ventilation. Herein we report the detailed course of a case that was successfully treated with extracorporeal membrane oxygenation as a bridge-to-recovery for warfarin- exacerbated diffuse alveolar hemorrhage.

Sedation in French intensive care units: a survey of clinical practice.
Sedation is used frequently for patients in intensive care units who require mechanical ventilation, but oversedation is one of the main side effects. Different strategies have been proposed to prevent oversedation. The extent to which these strategies have been adopted by intensivists is unknown. ⋯ Despite a low individual response rate, the respondents to our survey represent almost half of the ICUs in the French SRLF database. The presence of a written local sedation procedure, a cornerstone of preventing oversedation, is reported by only half of respondents; when present, it is used in for a limited number of patients. Sedation procedures mainly rely on titration of continuous IV hypnotics, but other strategies to limit oversedation also are included in sedation procedures. French intensivists no longer consider severely altered consciousness a sedation objective for most patients.
