Summary

The goal of this prospective, multicenter, single-arm clinical study is to learn whether a spontaneous breathing-preserving perioperative management strategy can improve recovery and is safe in lung transplant recipients with very low body weight (body mass index \[BMI\] \<16 kg/m²).

The main questions it aims to answer are whether, in lung transplant recipients with very low body weight (BMI \<16 kg/m²), a spontaneous breathing-preserving anesthesia-surgical strategy combined with standardized nutritional optimization and a prehabilitation program can improve early postoperative recovery and perioperative survival. Specifically, the study will assess the proportion of participants who require postoperative invasive mechanical ventilation, postoperative length of hospital stay, and perioperative survival within the protocol-defined time window (e.g., through hospital discharge).

Participants will undergo lung transplantation using a perioperative strategy that preserves spontaneous breathing whenever clinically appropriate, with predefined criteria for conversion to endotracheal intubation and mechanical ventilation if needed. They will receive standard postoperative monitoring and supportive care, with respiratory support events and perioperative complications assessed during the index hospitalization (and up to 30 days after surgery, if specified in the protocol). Key outcomes will be collected from routine clinical care, including postoperative ventilatory support status, length of hospital stay, and major safety events.

Interventions

PROCEDURE

Lung transplantation that preserves spontaneous breathing function

This intervention uses a spontaneous-breathing-preserving anesthesia strategy during lung transplantation, which differs from conventional management based on endotracheal intubation and invasive mechanical ventilation. A supraglottic airway (laryngeal mask airway) is used when feasible instead of endotracheal intubation to maintain spontaneous breathing throughout the procedure. Neuromuscular blocking agents are minimized, and regional nerve blocks (such as intercostal nerve blocks or paravertebral blocks) are used to control pain and suppress cough while preserving the patient's ability to breathe independently. After surgery, patients receive protocol-guided noninvasive respiratory support (for example, high-flow nasal oxygen or noninvasive ventilation), with the goal of avoiding routine invasive mechanical ventilation.
