Randomized Controlled TrialEvolution of practice patterns in the management of acute respiratory distress syndrome: A secondary analysis of two successive randomized controlled trials.
We sought to examine changes in acute respiratory distress syndrome (ARDS) management over a 12-year period of two successive randomized trials. ⋯ Clear trends were apparent in tidal volume, airway pressures, ventilator modes, adjuncts and rescue therapies. With the exception of prone positioning, and outside the context of rescue therapy, these trends appear consistent with the evolving literature on ARDS management.

Early detection and prevention of extubation failure offers the potential to improve patient outcome. The primary aim of this study was to compare the predictive ability of the Integrated Pulmonary Index and presence of high-risk factors in determining extubation failure. ⋯ Among subjects receiving mechanical ventilation for > 24 h, decreasing Integrated Pulmonary Index within the first hour postextubation was a predictor of extubation failure and was superior to other weaning variables collected in this retrospective study. The presence of ≥ 3 high-risk factors was also independently associated with extubation failure. Future clinical studies are required to prospectively test the ability of postextubation Integrated Pulmonary Index monitoring to guide additional interventions designed to reduce re-intubation rates and improve patient outcome.

Review Meta AnalysisEffect of different levels of PEEP on mortality in ICU patients without acute respiratory distress syndrome: systematic review and meta-analysis with trial sequential analysis.
To determine whether higher positive end- expiratory pressure (PEEP) could provide a survival advantage for patients without acute respiratory distress syndrome (ARDS) compared with lower PEEP. ⋯ Our results suggest that a lower PEEP ventilation strategy was non-inferior to a higher PEEP ventilation strategy in ICU patients without ARDS, with no increased risk of all-cause mortality and 28-day mortality. Further high-quality RCTs should be performed to confirm these findings.

The central nervous system during lung injury and mechanical ventilation: a narrative review.
Mechanical ventilation induces a number of systemic responses for which the brain plays an essential role. During the last decade, substantial evidence has emerged showing that the brain modifies pulmonary responses to physical and biological stimuli by various mechanisms, including the modulation of neuroinflammatory reflexes and the onset of abnormal breathing patterns. ⋯ This narrative review summarises current evidence of lung-brain crosstalk in patients receiving mechanical ventilation and describes the clinical implications of this crosstalk. Further, it proposes directions for future research ranging from identifying mechanisms of multiorgan failure to mitigating long-term sequelae after critical illness.
