Patient‐reported outcomes of laryngeal mask anesthesia in thoracoscopic pulmonary wedge resection: A randomized controlled study

BACKGROUND: To assess the effectiveness and safety of laryngeal mask anesthesia (LMA) in thoracoscopic pulmonary wedge resection based on patient‐reported outcomes (PROs). METHODS: This randomized controlled trial included 107 patients who underwent thoracoscopic pulmonary wedge resection between June 2017 and December 2021 for pulmonary nodule or pulmonary bullae. In one group, LMA was applied for general anesthesia, and in the other group, endotracheal intubation (ETT) was used. RESULTS: A total of 107 patients were included in the study. The symptom assessment based on PROs showed that the incidence of pharyngodynia, trachyphonia, and cough were lower in the LMA group, while the postoperative gastrointestinal reaction did not significantly differ between the two groups. The pain score and global satisfaction score were significantly better in the LMA group. The satisfaction degree of anesthesia and the surgical field did not significantly differ between the two groups. The anesthesia recovery time, indwelling days of chest catheter, and postoperative hospital stay of the LMA group were all shorter, while the operation time, intraoperative blood loss and lowest intraoperative oxygen saturation did not significantly differ between the two groups. The highest intraoperative partial pressure of CO(2) was significantly higher in the LMA group. The artery blood gas analysis after the operation did not significantly differ between the two groups. CONCLUSION: Compared with ETT, the application of LMA may demonstrate promising advantages in airway management for thoracoscopic pulmonary wedge resection.
