目的：分析喉罩在肥胖患者眼科日间手术中的应用特点。方法：选择 2021 年 1 月— 2024 年 3 月在中山大学中山眼科中心行日间眼科手术 且体质量指数（body mass index，BMI）≥25 kg/m²的男性患者进行分析，将患者分为2组：超重组（BMI 25~<30 kg/m2）及肥胖组（BMI≥30 kg/m²）。比较两组患者入室时（T₁）、诱导后（T₂）、喉罩置入后（T₃）、手术开始时（T₄）、手术开始10 min（T₅）、手术结束时（T₆）、入麻醉恢复室（post-anesthesia care unit，PACU）（T₇）、喉罩拔除时（T₈）的血流动力学和血氧饱和度变化情况；并分析喉罩置入后（T₃）、手术开始时（T₄）、手术开始10 min（T₅）、手术结束时（T₆）和喉罩拔除时（T₈）患者的呼吸参数变化情况，记录两组患者的喉罩通气成功率及复苏室的停留时间。结果：纳入 118 例患者，其中超重组 57 例、肥胖组 61 例。两组均未出现喉罩通气失败病例，肥胖组在T₃、T₄、T₅、T₆以及T₈等时点气道峰压均高于超重组（P < 0.05）；肥胖组的呼吸道不良事件发生率高于超重组（P < 0.05）。两组患者围术期生命体征平稳（P > 0.05），复苏室停留时间在组间比较差异无统计学意义（P > 0.05）且均顺利日间手术离院。结论：喉罩通气下全身麻醉能安全应用在肥胖患者眼科日间手术中，高BMI与高气道峰压相关。

Objective: General anesthesia using laryngeal mask airway (LMA) ventilation can facilitate ambulatory ophthalmic surgery, however, there remains debates about the use of LMA for obese patients. This study retrospectively analyzed the application of LMA in obese patients for ambulatory ophthalmic surgery. Methods: In this retrospective study, we analyzed all patients with a BMI≥25 kg/m2 who underwent ambulatory ophthalmic surgery under general anesthesia at the Zhongshan Ophthalmic Center of Sun Yat-sen University from January 2021 to March 2024.  The patients were divided into two groups: overweight group (BMI 25~<30 kg/m2) and obese group (BMI ≥30 kg/m2) . We compared the changes in hemodynamics and oxygen saturation at the several time points, baseline after entering operating room (T₁), anesthesia induction (T₂), LMA insertion (T₃), start of surgery (T₄), 10 minutes after surgery (T₅), surgery completion (T₆), transfer to PACU (T₇), and LMA removal (T₈);and analyzed the changes in respiratory parameters of the patient at T₃, T₄, T₅, T₆, and T₈ time points between both groups. We also observed the differences in success rate of LMA insertion and ventilation and PACU stay time as well as time to discharge home between two groups. Results: 118 cases were found suitable for the final analysis and divided into overweight group (n=57) and obese group (n=61). All patients in the two groups uneventfully completed the ophthalmic ambulatory surgery and discharged home under the laryngeal mask airway ventilation, none of patients in both group displayed LMA ventilation failure. The hemodynamics and oxygen saturation in both groups were stable during perioperative period(P > 0.05). The peak airway pressures in obese group were dramatically increased than in overweight group at T₃, T₄, T₅, T₆ and T8 time points (P < 0.05), and the incidences of adverse respiratory events in obese group were significant higher than in overweight group （P < 0.05）. The PACU stay time was comparable in both groups (P > 0.05). Conclusion: LMA can be safely used for obese patients undergoing ophthalmic surgery, high BMI is related to high peak airway pressures.

目的：分析全身麻醉在青光眼日间手术中的应用特点。方法：回顾性收集2023年1月—6月于中山大学中山眼科中心在全身麻醉下接受青光眼日间手术患者71例(全麻组)，并选择同时期在局部麻醉下接受青光眼手术患者154例(局麻组)，同时以年龄为配对因素行倾向评分匹配分析。主要观察指标为患者术后离院时间，并对患者的手术时间、手术前后眼压、视力、中央前房深度、周边前房深度、甘露醇使用情况以及术后较术前眼压降低差值进行分析。结果：与局麻组比较，全麻组患者术后离院时间未有延长(P>0.05)；全麻组患者术前眼压较高(P<0.001)、中央前房深度浅(P=0.018)、周边前房深度浅(P<0.001)；且全麻组患者在术后较术前眼压降低差值更大(P=0.002)。组间术后中央前房深度、术后使用甘露醇者比例及术后视力提高者比例比较差异均无统计学意义(P>0.05)。结论：术前眼部条件较差的青光眼患者能在全身麻醉下完成日间手术，且不延长术后离院时间。

Objective: To analyze the application of general anesthesia in the ambulatory glaucoma surgery. Methods: This retrospective study collected 71 patients who underwent ambulatory glaucoma surgery with general anesthesia at Zhongshan Ophthalmic Center of Sun Yat-sen University from January 2023 to June 2023, and 154 patients who underwent similar glaucoma surgery with local anesthesia during the same period. Age differences between the two groups were balanced by propensity score-matched analysis. The main outcome measures were the patients' post-operative discharge time, and the secondary end points included the duration of surgery, the patients' preoperative and postoperative intraocular pressure (IOP), visual acuity status, central anterior chamber depth, peripheral anterior chamber depth, mannitol use, the difference in IOP reduction after surgery compared to preoperative. Results: After propensity score-matched analysis, as compared with group L, general anesthesia did not prolong the patients' post-operative discharge time(P>0.05).Patients in the group G displayed significant higher IOP (P<0.001), shallower central anterior chamber depth (P=0.018), and shallower peripheral anterior depth (P<0.001). The dramatic reductions in IOP after surgery were exhibited in group G as compared with group L(P=0.002). There were no statistically significant differences in postoperative central anterior chamber depth, incidences in postoperative mannitol use, as well as incidences in visual acuity improvement on the first day after surgery. Conclusion: Glaucoma patients with poor preoperative ocular conditions were able to complete the complex glaucoma surgery under general anesthesia without prolonging their post-operative discharge time.

Objective: The aim of this study is to observe the efficacy and safety of propofol-alfentanil-lidocaine mixture in adult patients for cataract ambulatory surgery. Methods: Thirty adult patients undergoing cataract ambulatory surgery sedated by propofol-alfentanil-lidocaine mixture from January 2021 to June 2021 were enrolled in this retrospective study (sedation group, n=30). Meanwhile, another thirty patients with similar diagnosis performed by the same surgeons under topical anesthesia were matched in this study (topical anesthesia group, n=30). The scores of intraoperative eye position, the number of surgical interruptions due to poor cooperation, surgical time, emergence time, time to discharge, changes in blood pressure, surgical experience, as well as any adverse events were compared between the two groups. Results: The surgeries were successfully completed in all patients in both groups. Compared to topical anesthesia group, patients under sedation showed less surgical interruptions and more stable hemodynamics during the surgery, as well as better surgical experience (all P<0.05). Conclusion: Sedation with propofol-alfentanil-lidocaine mixture can significantly improve the surgical experience of patients undergoing cataract ambulatory surgery without prolonging duration of the surgery.

Objective: To observe the eye position, the incidence of eye movement and the efficacy of propofol on correcting eccentric eyeball position in children undergoing examination of outpatient fundus fluorescein angiography (FFA) with inhaled sevoflurane via laryngeal mask airway. Methods: Children undergoing FFA with sevoflurane anesthesia from June 2018 to December 2019 were retrospectively reviewed. Eye position at the beginning of examination, incidence of eye movement during examination, the efficiency of propofol on correcting eccentric eyeball position during procedure, the time to resume normal activities, and adverse events were recorded. Results: Fifty-four children aged 1–9 years were included in this study. The rates of eye position from grade one to grade three at the beginning of examination were 42.6% (23/54), 51.9% (28/54), and 5.6% (3/54), respectively. The incidence of eye movement during examination was 61.1% (33/54). 13% (7/54) of children with unsatisfactory eye-position needed intervention with propofol. The efficacy of propofol (1 mg/kg) in correcting eye position was 100%. The mean time to return normal activities was 24.4 min. There were no any adverse events during the peri-anesthetic period. Conclusion: Inhaled sevoflurane via LMA can provide appropriate anesthesia for outpatient FFA in children. Children can resume daily activities soon after anesthesia. Propofol can return the incorrect eye position during examination
