Editorial Randomized Controlled Trial Multicenter Study
THE ASSOCIATION BETWEEN PHYSIOLOGIC DEAD-SPACE FRACTION AND MORTALITY IN PATIENTS WITH THE ACUTE RESPIRATORY DISTRESS SYNDROME ENROLLED INTO A PROSPECTIVE MULTI-CENTERED CLINICAL TRIAL.
We tested the association between pulmonary dead-space fraction (ratio of dead space to tidal volume [V(D)/V(T)]) and mortality in subjects with ARDS (Berlin definition, P(aO2)/F(IO2) ≤ 300 mm Hg; PEEP ≥ 5 cm H2O) enrolled into a clinical trial incorporating lung-protective ventilation. ⋯ Markedly elevated V(D)/V(T) (≥ 0.60) in early ARDS is associated with higher mortality. Measuring V(D)/V(T) may be useful in identifying ARDS patients at increased risk of death who are enrolled into a therapeutic trial.

EditorialNewly identified precipitating factors in mechanical ventilation-induced brain damage: implications for treating ICU delirium.
Delirium is 1.5 to 4.1 times as likely in intensive care unit patients when they are mechanically ventilated. While progress in treatment has occurred, delirium is still a major problem in mechanically ventilated patients. ⋯ This argues for minimizing the duration and tidal volumes of mechanical ventilation and for more effectively reducing sustained D2R signaling than achieved with haloperidol alone. The latter might be accomplished by reducing D2R cell surface expression and D2R-mediated Akt inhibition by elevating protein expression of dysbindin-1C.
