Multicenter StudyICU physicians' and nurses' perceptions of terminal extubation and terminal weaning: a self-questionnaire study.
Terminal extubation (TE) and terminal weaning (TW) are the methods available for withdrawing mechanical ventilation. Perceptions of TE and TW by intensive care unit (ICU) staff may influence bedside practices and the feasibility of studies comparing these methods. ⋯ Nearly two-fifths of ICU nurses and physicians in participating ICUs preferred TW or TE. This finding suggests both a need for shared decision-making and training before performing TE or TW and a high risk of poor compliance with randomly allocated TW or TE.

Meta AnalysisVolatile Agents in Medical and Surgical Intensive Care Units: A Meta-Analysis of Randomized Clinical Trials.
To comprehensively assess published randomized peer-reviewed studies related to volatile agents used for sedation in intensive care unit (ICU) settings, with the hypothesis that volatile agents could reduce time to extubation in adult patients. ⋯ In this meta-analysis of randomized trials, volatile anesthetics reduced time to extubation in medical and surgical ICU patients. The results of this study should be confirmed by large and high-quality randomized controlled studies.

Lung transplantation (LTx) has become an accepted treatment for carefully selected patients with end-stage lung disease. Critical care issues have gained importance concerning bridging of candidates by mechanical respiratory support and are involved in the care after transplantation. The nature of respiratory support varies from oxygen supply and noninvasive ventilation, to mechanical respiratory support either by mechanical ventilation and/or extracorporeal life support. ⋯ Primary graft dysfunction and prolonged mechanical ventilation are major obstacles to hospital survival after LTx. Clear evidence is lacking on how to ventilate and optimally manage patients after LTx. Prolonged extracorporeal life support after LTx may improve outcome in selected patients with a primary graft dysfunction.

Hospital emergency department (ED) strain is common in North America. Excessive strain may result in prolonged ED length of stay and may lead to worse outcomes for patients admitted to intensive care units (ICUs). ⋯ In this population-based study, less than half of adult ED patients were admitted to an ICU 6 hours or less after arrival to an ED, an internationally recognized performance indicator for ED care quality. ED and ICU strain generated by time-varying demand on capacity was an important determinant of ED length of stay. However, prolonged length of stay in an ED did not measurably reduce 90-day mortality.

Ultrasonographic assessment of diaphragm function with patients on low levels of pressure support (PS) predicts extubation outcomes, but similar information regarding extubation success under other conditions is lacking. The purpose of this study was to determine whether ultrasound (US) measurements of the diaphragm made on various levels of PS can predict time until successful extubation. ⋯ Diaphragm US is a valid predictor of extubation success at some but not all PS settings. Using a ∆tdi% of 20 % on PS levels up to 10/5 cm of H2O may reduce both unnecessarily prolonged intubations and prevent emergent reintubations.
