Reducing Pneumonia with LMA in Lung Wedge Resection

Sponsor: Hai Feng

Summary

This retrospective cohort study aims to evaluate whether spontaneous breathing laryngeal mask anesthesia (LMA-SBA) reduces the incidence of postoperative pneumonia compared to single-lung isolation mechanical ventilation in patients undergoing thoracoscopic wedge resection. Using propensity score overlap weighting, we will adjust for multiple confounders, including age, COPD, surgical duration, and preoperative laboratory values. Secondary outcomes include postoperative recovery time, fever severity, white blood cell count, neutrophil percentage, length of hospital stay, and ICU admission rate. The study has been approved by the Ethics Committee of the First Affiliated Hospital of Shandong First Medical University (Approval No. YXLL-KY-2025(037)).
