目的：评估右美托咪定复合舒芬太尼用于老年青光眼患者经巩膜二极管激光睫状体光凝术 (transscleral diode laser cyclophotocoagulation，TDLC)术后自控静脉镇痛(patient-controlled intravenous analgesia，PCIA)的安全性和有效性。方法：选择行TDLC术老年青光眼患者80例，采用随机数字表法将患者分为SD组(n=40)和S组(n=40)。SD组术后PCIA采用舒芬太尼1.5μg/kg+右美托咪定1.5 μg/kg+托烷司琼4mg；S组采用舒芬太尼2μg/kg+托烷司琼4mg。将相应药物置入生理盐水配成100mL混合液加入电子镇痛泵，手术结束即刻行PCIA至术后24h。观察比较两组患者基本情况和手术情况，比较术前(T0)、术后即刻(T1)、术后6h(T2)、术后12h(T3)和术后24h(T4)患者的收缩压(systolic blood pressure，SBP)、舒张压(diastolic blood pressure，DBP)、心率(heart rate，HR)、NRS疼痛评分、Ramsay镇静评分及非手术眼的眼内压(intraocular pressure，IOP)，比较术后恶心呕吐、呼吸抑制、躁动等不良反应及使用其他辅助镇痛药物的情况。结果：两组患者基本情况和手术情况的差异无统计学意义。两组各时点DBP、非手术眼IOP及NRS评分差异无统计学意义。SD组T3、T4时点SBP，T2、T3、T4时点HR以及T2、T3时点Ramsay评分均低于S组，差异有统计学意义(P<0.05)。两组患者发生不良反应的总例数差异无统计学意义，但SD组恶心呕吐(1例)和烦躁(2例)发生率均低于S组(分别为6例和9例)，差异有统计学意义(P<0.05)。两组患者呼吸抑制和眩晕嗜睡发生率以及使用其他辅助镇痛药物例数差别无统计学意义，SD组舒芬太尼使用量低于S组(P<0.05)。结论：采用右美托咪定1.5μg/kg复合舒芬太尼1.5μg/kg行PCIA时不影响非手术眼IOP，可安全有效地应用于老年青光眼患者TDLC术后镇痛。

Objective: To evaluate the safety and efficacy of dexmedetomidine combined with sufentanil for postoperative patient-controlled intravenous analgesia (PCIA) after transscleral diode laser cyclophotocoagulation (TDLC) in elderly patients with glaucoma. Methods: Eighty elderly glaucoma patients undergoing TDLC were selected and randomly divided into a SD group (n=40) and a S group (n=40) by random number table method. In SD group (n=40), sufentanil 1.5 μg/kg, dexmedetomidine 1.5 μg/kg and tropisetron 4 mg were used for postoperative PCIA, and sufentanil 2 μg/kg and tropisetron 4 mg were used in S Group (n=40). The corresponding drugs in saline solution was added into 100 mL solution with electronic analgesia pump. PCIA was performed immediately after the operation until 24 h after the operation. The basic condition and operation situation of the two groups were observed and compared, and systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), NRS pain score, Ramsay sedation score and non-operation eye intraocular pressure (IOP) at preoperative (T0), after operation (T1), postoperative 6 h (T2), 12 h after operation (T3) and 24 h after operation (T4) were compared, and postoperative adverse reactions such as nausea and vomiting, respiratory depression, restlessness and use of other auxiliary analgesic drug were also compared. Results: There was no significant difference between two groups of patients’ basic and surgical conditions. There was no significant difference between two groups at each time point DBP, non-operation eye IOP and NRS score. SBP at T3 and T4, HR at T2, T3 and T4, and Ramsay score at T2 and T3 in SD group were lower than the S group, the difference was statistically significant. There was no significant difference in the total number of adverse reactions between two groups, but the incidence of nausea and vomiting and restlessness in group SD were lower than those in group respectively, the difference was statistically significant (P<0.05). There was no significant difference between the two groups in the incidence of respiratory depression, dizziness, lethargy and the use of other auxiliary analgesics. The sufentanil usage in group SD was lower than that in group S (P<0.05). Conclusion: PCIA with dexmedetomidine 1.5 g/kg combined with sufentanil 1.5 g/kg does not affect the non-operation eye IOP. It can be safely and effectively applied to postoperative analgesia for elderly patients with glaucoma after TDLC

目的：对比喉罩与气管插管在小儿眼科全身麻醉中的应用情况，选取小儿全身麻醉的适宜气道管理方式。方法：选取2019年6月至2021年4月在天津市眼科医院进行眼科全身麻醉手术的86例患儿为研究对象，根据全身麻醉诱导后置入气管导管或喉罩分为插管组与喉罩组，每组43例。麻醉诱导后插入气管导管或喉罩后实施容量控制通气。通过回顾收集麻醉记录单查询麻醉诱导前(T0)、麻醉诱导后(T1)、插入气管导管或喉罩时(T2)、手术开始时(T3)、手术结束时(T4)、移除喉罩或气管导管时(T5)检测心率、平均动脉压，以及插管后5、10、20 min时的平均气道压和呼气末CO2分压。根据麻醉记录单查询每例患者气管插管或喉罩置入的次数、苏醒期呛咳及躁动的发生情况。比较2组麻醉时间、置管/喉罩首次成功率、拔管/撤罩时间、自主呼吸恢复时间、麻醉复苏时间。观察2组患者并发症(呛咳、躁动发生情况)的发生情况。结果：在T2、T3和T5时，插管组心率明显高于喉罩组，差异有统计学意义(P<0.05)；在T2、T3、T4和T5时，插管组平均动脉压明显高于喉罩组，差异有统计学意义(P<0.05)。插管后5、10和20 min时，插管组平均气道压均高于喉罩组，差异有统计学意义(P<0.05)。2组不同时间点呼气末CO2分压的比较，差异无统计学意义(P<0.05)。喉罩组麻醉复苏期间呛咳和躁动的发生率明显低于插管组，差异有统计学意义(P<0.05)。结论：喉罩具有操作简单、对气道刺激较小等优点，用于小儿眼科全身麻醉时对血流动力学的影响较小，气道反应性低，并发症较少，值得在临床推广使用。

Objective: To select the appropriate airway management mode for children under general anesthesia by comparing the application of laryngeal mask and endotracheal intubation in pediatric ophthalmology. Methods: A total of 86 children who underwent ophthalmic general anesthesia surgery in our hospital in June 2019 and April 2021 were selected as the study subjects, and the tracheal catheter or laryngeal mask was placed after induction of general nesthesia, and the group of 43 cases were divided into intubation group and laryngeal mask group. Volumecontrolled ventilation is performed after induction of anesthesia after insertion of a tracheal catheter or laryngeal mask. Heart rate and mean arterial pressure were detected by retrospectively collecting anesthesia records alone before anesthesia induction (T0), after anesthesia induction (T1), when a tracheal catheter or laryngeal mask was inserted (T2), at the beginning of surgery (T3), at the end of surgery (T4), and when the laryngeal mask or tracheal catheter was removed (T5). As well as the average airway pressure and end-expiratory CO2 partial pressure at 5, 10, and 20 min after intubation. The number of endotracheal intubations or laryngeal hoods, the occurrence of cough during awakening, and agitation in each patient was queried according to the anesthesia record. The timing of anesthesia, the first success rate of catheterization/laryngeal mask, the time of extubation/uncommissioning, the time of spontaneous breathing recovery, and the time of anesthesia resuscitation were compared between the 2 groups. The occurrence of complications (choking cough, agitation) in both groups of patients was observed. Results: At T2, T3 and T5, the heart rate in the intubation group was significantly higher than that in the laryngeal mask group (P<0.05), and at T2, T3, T4 and T5, the mean arterial pressure in the intubation group was significantly higher than that in the laryngeal mask group(P<0.05). At 5, 10, and 20 min after intubation, the mean airway pressure in the intubation group was higher than that in the laryngeal mask group, and the difference was statistically significant (P<0.05). There was no statistical difference in the partial pressure of CO2 at the end of expiratory breath at different time points between the 2 groups (P<0.05). The incidence of choking cough and agitation during anesthesia resuscitation in the laryngeal mask group was significantly lower than that in the intubation group, and the difference was statistically significant (P<0.05). Conclusion: The laryngeal mask has the advantages of simple operation and less stimulation of the airway, and when used for pediatric ophthalmic general anesthesia, it has less hemodynamic effect, low airway responsiveness and fewer complications, and is worth promoting in clinical practice
