Actual (reported)Nonintubated anesthesia applied in combination with high-flow nasal oxygen (HFNO) is an alternative strategy for laryngeal microsurgery (LMS). LMS is a common procedure in otolaryngology that typically requires endotracheal tube intubation under general anesthesia. Endotracheal tube intubation causes complications; a nonintubated strategy can avoid these complications and provide a clearer surgical field of vision, enabling vocal cord inspection and disposal. Administering a muscle relaxant can also help prevent bucking during surgery but can engender apnea and hypercapnia, which may have negative effects on hemodynamics. Therefore, the investigators assessed the effectiveness of a superior laryngeal nerve block (SLNB) with intravenous general anesthesia in maintaining spontaneous breathing and improving safety during LMS with nonintubated anesthesia.
