简要总结
EARLY-VENT is a multicenter, open-label, three-period cluster-randomized crossover trial designed to evaluate whether early transition from controlled to assisted ventilation improves outcomes in critically ill patients. The study will enroll approximately 1,600 adult patients across 10 ICUs who are expected to require mechanical ventilation for at least 48 hours and meet specific stability criteria (e.g., hemodynamically stable, light sedation). Participating centers will alternate between an experimental strategy, where patients transition to an assisted mode (preferably Pressure Support Ventilation) within 6 hours of eligibility, and a control strategy based on standard care practices. The primary endpoint is the rate of successful extubation at day 28, aiming to demonstrate that transition from controlled to assisted ventilation can reduce ventilation duration and improve prognosis compared to delayed transition.

主要结局
the rate of successful extubation at day 28
时间窗: the rate of successful extubation at day 28
1. No re-intubation or death occurred for 7 consecutive days after extubation, or the patient survived ICU admission with non-invasive mechanical ventilation within 7 days post-extubation-whichever occurs first. 2. For tracheostomy patients: Successful extubation is defined as achieving spontaneous ventilation through the tracheostomy for seven consecutive days without any form of assisted ventilation, or discharge from the ICU without assisted respiratory support, whichever occurs first.
