Laryngeal mask anesthesia in video-assisted thoracoscopic surgery for pulmonary bulla: comparison with intubation anesthesia / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To assess the feasibility and safety of thoracoscopic bulla resection under laryngeal mask anesthesia with low tidal volume high-frequency lung ventilation.</p><p><b>METHODS</b>Sixty patients with pulmonary bulla were randomized into two groups (n=30) to undergo video-assisted thoracoscopic surgery (VATS) for bulla resection with laryngeal mask anesthesia and high-frequency low tidal volume lung ventilation general anesthesia and or with intubation anesthesia and one-lung ventilation through double-lumen endotracheal intubation.</p><p><b>RESULTS</b>No significant differences were found in anesthesia time, surgery time, intraoperative lowest SpO2, intraoperative highest PetCO2, operative field, anesthetic effects, or blood loss between the two groups. The post-operative WBC and NEU% showed significantly smaller increments in the mask anesthesia group than in the intubation group, and the postoperative awake time, initial eating time, ambulation time, in-hospital stay, and drainage time were significantly shortened in the former group with also lower incidences of gastrointestinal reactions, throat discomfort and hoarseness.</p><p><b>CONCLUSION</b>Thoracoscopic bulla resection under laryngeal mask anesthesia with low tidal volume high-frequency lung ventilation is safe and feasible and results in better patient satisfaction and shorter in-hospital stay than procedures performed under intubation anesthesia with one-lung ventilation.</p>
