Efficacy of Different Anesthesia Methods in Transbronchial Biopsy

General anesthesia and local anesthesia are the primary anesthesia methods for interventional respiratory endoscopy. While general anesthesia offers greater comfort, it carries anesthesia-related risks. Local anesthesia, on the other hand, provides a relatively low surgical risk and cost-effectiveness. However, there is limited research on whether its diagnostic value is inferior to that of general anesthesia.This study investigates the efficacy of the two anesthesia methods (general anesthesia with laryngeal mask airway and local nebulized anesthesia) for transbronchial biopsy. The study retrospectively analyzed cases of transbronchial biopsy performed at the Respiratory Endoscopy Center of Sichuan Provincial People's Hospital from June 5, 2020, to June 5, 2024. Data collected included age, gender, primary diagnosis, anesthesia method, biopsy method(forcep/cryobiopsy), operation time (excluding general anesthesia and laryngeal mask airway placement time), lesion location and size, pathological results, and follow-up status(pneumothorax、hemorrhage).

Inclusion criteria

• Completed Transbronchial Biopsy；the platelets count and PT, APTT tests were normal, normal ECG, Anesthesiologist evaluation was needed in General anesthesia group.

Exclusion criteria

• patients with contraindication of bronchoscopy (such as respiratory failure and acute cardio-cerebrovascular events), and women who were pregnant.
