Evaluation of the Safety and Rapid Recovery Effect of the Tubeless Strategy in Lung Transplantation: a Prospective, Multicenter, Partially Double-blind, Randomized Controlled Clinical Study

Patients undergoing this surgery receive lung transplantation surgery without standard tracheal intubation. Instead, they will breathe on their own using a special airway device called a laryngeal mask airway (LMA), combined with a bronchial blocker to separate lung ventilation during surgery. Sedation is maintained with intravenous medications (propofol, remifentanil, and dexmedetomidine), and participants will remain spontaneously breathing or receive minimal breathing assistance as needed. The surgical incision will be numbed using local anesthesia with lidocaine and ropivacaine injections. After surgery, the LMA will be removed in the operating room, and participants will transition directly to non-invasive breathing support before being monitored in the ICU.
