A case study of airway management using laryngeal mask airway combined with Bronchial blocker for surgical treatment of tracheal tumors with pulmonary nodules

A 60-year-old female with a tracheal tumor near the glottis and a lung nodule underwent surgery for resection. The tumor's proximity to the glottis prevented the safe use of a tracheal tube, as it risked crossing the tumor and causing injury. Given this challenge, a 4^# single-lumen laryngeal mask airway (LMA) was used in combination with a 9^# bronchial blocker to achieve one-lung ventilation. This approach minimized the risk of tracheal injury, bleeding, and tumor dissemination. The procedure, including the resection of the lung nodule and tracheal tumor, was completed successfully, with stable postoperative recovery. This case demonstrates the efficacy of LMA and bronchial blocker in complex airway management.
