The equivalent dose of sufentanil and afentanil combined with laryngeal mask was used for complex bronchoscopy to observe the intraoperative effect and the influence on the recovery of patients

Afentanil is a powerful, fast-acting narcotic analgesic, which can effectively inhibit intubation reflex. Compared with sufentanil, it has a short half-life and is safer, and can be used as the first choice for short surgical analgesics. In this study, by comparing the use of equivalent dose sufentanil and afentanil combined with laryngeal mask for complex bronchoscopy, the intraoperative analgesic effect and the influence on the recovery of patients were observed, and a better anesthesia scheme was provided for tracheoscopy.
