目的：探究可弯曲喉罩在经鼻内镜眼科日间手术中应用的安全性。方法：收集2023年1月—2024年1月在全身麻醉(全麻)下行经鼻内镜眼科日间手术成年患者资料，分析可弯曲喉罩使用的成功率，观察患者入室时、插管后、手术开始时、手术结束时的血流动力学变化情况；并记录喉罩置入后、手术开始5 min、手术开始30 min和手术结束时的呼吸参数及患者在麻醉恢复室（post-anesthesia care unit，PACU的停留期间的并发症。结果：共635例患者纳入分析，其中619例患者选用喉罩，607例患者喉罩置入成功，成功率98.1%，喉罩置入失败12例，均为诱导期间置入失败，占1.9%，无术中发生喉罩通气失败改气管插管病例。喉罩通气能满足经鼻内镜手术需求，表现为各时点通气量无显著变化及平稳的心率和平均动脉压。患者均顺利复苏，PACU停留时间为(34.6±11.2) min，喉罩拔除时间为(14.3±4.3) min，无二次气管内插管事件发生。结论：置入成功的可弯曲喉罩可安全应用在经鼻内镜眼科日间全麻手术中。

Objective: To investigate the safety of flexible laryngeal masks in the application of endoscopic ophthalmic ambulatory surgery. Methods: Data of adult patients undergoing endoscopic day ophthalmic surgery under general anesthesia from January 2023 to January 2024 were collected; the changes in hemodynamics at T1 (entry into the operating room), T2 (after intubation), T3 (before surgery), and T6 (after surgery) time points and the respiratory parameters at T2 (after intubation), T4 (5 minutes after surgery), T5 (30 minutes after surgery), and T6 (after surgery) time points were analyzed; meanwhile, the complications during the PACU stay were also analyzed. Results: A total of 635 patients were included in the retrospective analysis, of whom 619 patients were initially used FLMA, FLMA were successfully inserted in 607 patients with a rate of 98.1% while 12 patients suffered insertion failure during the period of anesthesia induction. Importantly, none of patients displayed FLMA ventilation failure and required tracheal intubation during the period of surgery. General anesthesia via FLMA ventilation can provide high quality of surgical field for endoscopic ophthalmic surgery, as evidenced by stable heart rates and mean arterial pressure and no significant change in minute ventilation at each time points. All patients recovered uneventfully with a PACU stay time of 34.6±11.2 min and FLMA removal time of (14.3±4.3) min. None of patients exhibited subsequently endotracheal intubation after FLMA removal. Conclusion: FLMA with successful placement can be safely used for endoscopic ophthalmic ambulatory surgery under general anesthesia.
