Application of Ventilating-Bronchoscopy-Adaptor by Fusing a Laparoscopic Trocar during Bronchial Thermoplasty under General Anesthesia

Bronchial thermoplasty (BT) is a novel procedure for patients with severe asthma who are refractory to pharmacotherapy.1,2 BT reduces this airway smooth muscle mass by applying radiofrequency energy to large airways.3 Although BT is generally performed under topical anesthesia and sedation, general anesthesia is needed when a patient is unable to cooperate or when unstable vital signs are expected.1 General anesthesia is also performed when it is considered necessary in the guidelines of institutional practice.1 When BT is performed under general anesthesia, air leakage in the bronchoscopy adaptor frequently develops during the procedure and thus mechanical ventilation becomes unstable. We solved this problem by fusing the flexible catheter mount to a trocar used in laparoscopic surgery
