There is currently no standardized way to determine suitability for extubation of pediatric ICU (PICU) patients, potentially resulting in prolonged duration of mechanical ventilation. We aimed to design and implement a protocol for screening all intubated PICU patients for extubation readiness. ⋯ An acceptable and safe ERT protocol was implemented and found to improve outcomes in PICU subjects on mechanical ventilation.

Randomized Controlled Trial
The PROMIZING trial enrollment algorithm for early identification of patients ready for unassisted breathing.
Liberating patients from mechanical ventilation (MV) requires a systematic approach. In the context of a clinical trial, we developed a simple algorithm to identify patients who tolerate assisted ventilation but still require ongoing MV to be randomized. We report on the use of this algorithm to screen potential trial participants for enrollment and subsequent randomization in the Proportional Assist Ventilation for Minimizing the Duration of MV (PROMIZING) study. ⋯ The trial algorithm permitted identification of 93 (25%) patients who were ready to extubate, while their clinicians predicted a duration of ventilation higher than 24 h.

Whether targeting the driving pressure (∆P) when adjusting the tidal volume in mechanically ventilated patients with the acute respiratory distress syndrome (ARDS) may decrease the risk of ventilator-induced lung injury remains a matter of research. In this study, we assessed the effect of a ∆P-guided ventilation on the mechanical power. ⋯ As compared to a conventional PBW-guided ventilation, a ∆P-guided ventilation strategy targeting a ∆P between 12 and 14 cm H2O required to change the tidal volume in 90% of the patients. Such ∆P-guided ventilation significantly reduced the mechanical power. Whether this physiological observation could be associated with clinical benefit should be assessed in clinical trials.
