Shenfu Injection for the Prevention and Treatment of Ventilator Dependence in Mechanically Ventilated Patients

This multicenter randomized controlled trial aims to evaluate the efficacy of Shenfu Injection in preventing and treating ventilator dependence and ventilator-induced diaphragm dysfunction (VIDD) in critically ill adult patients receiving invasive mechanical ventilation. Eligible participants will be randomly assigned to receive Shenfu Injection or control treatment in addition to standard clinical care. Diaphragm function will be monitored using daily bedside ultrasonography, including diaphragm excursion and diaphragm thickness. Clinical outcomes will include successful ventilator weaning, time to successful weaning, and the need for resumption of mechanical ventilation within 48 hours after initial weaning. The study is intended to determine whether Shenfu Injection can improve diaphragm function and facilitate liberation from mechanical ventilation.
