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

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

Objective: To construct an ideal and practical method for managing ophthalmic high-value surgical supplies to strengthen the management of ophthalmic operating room. Methods: A visual management system of ophthalmic high-value surgical supplies was established by using information technology connected with hospital information systems, then the data were integrated to construct a monitoring system for real-time status of ophthalmic high-value surgical supplies, including the whole life cycle management of the surgical supplies. Results: Through the establishment of the system for whole life cycle of high-value ophthalmic surgical supplies, the whole process management realized the supplies for preoperative control, intraoperative monitoring and postoperative trace. Conclusion: Constructing the system solves the daily management problem of ophthalmic high-value surgical supplies, reduces the blind area of management, and strengthens the supervision of surgical supplies in the ophthalmic operating room.

近年来，眼科手术后的疼痛受到关注，部分患者术后表现出疼痛区域扩大，神经性畏光。术后这种 对伤害性刺激性信号反常性增加的现象称之为痛觉过敏。痛觉过敏的发展会导致患者延迟术后恢 复等问题。此外，痛觉过敏还会引起患者不适，诱使患者使用更多的止痛药而产生相关的不良反 应。而TRPV1/TRPA1是一种伤害性感受器，能够被伤害性刺激特异性激活而诱发痛觉过敏。尽管 如此，目前关于眼科术后的痛觉过敏发病机制未完全阐明，TRPV1如何增敏导致痛觉过敏的分子生 物学过程尚未明确。

The postoperative pain of ophthalmic surgery has been widely concerned in recent years. Some patients show enlarged painful areas and neurophotophobia postoperatively. This abnormal increase in noxious irritant signals after surgery is called hyperalgesia. The development of hyperalgesia can result in delayed postoperative recovery for patients. In addition, hyperalgesia can also cause discomfort for patients, and induce patients to use more analgesics, which can have related side effects. TRPV1/TRPA1 is a nociceptor, which can be specifically activated by nociceptive stimuli to induce hyperalgesia. Nevertheless, the pathogenesis of hyperalgesia after ophthalmology surgery has not been fully elucidated, and the molecular signal pathway of how TRPV1 sensitizes and causes hyperalgesia is not yet clear. 

球后阻滞是眼科手术中常见的麻醉方式之一，若操作不当，可造成严重并发症，包括局部麻醉药物的毒性反应等。现报告1例26岁诊断为“视网膜脱离”拟行眼底手术的女性患者，在球后阻滞10min后，患者出现心率增快、血压升高后下降、吞咽困难、声音嘶哑、呼吸困难及SpO2下降，伴随对侧眼球运动障碍，全身肌力下降等临床表现。及时给予生命支持等对症处理后，患者上述临床表现好转，并随后在全身麻醉下完成手术。

Retrobulbar block is one of the common anesthesia methods in ophthalmic surgery, however, misconducting the procedure would result in severe complications including central toxicity from local anesthetics. This study presented a 26-year-old female patient diagnosed retinal detachment for retinal surgery under retrobulbar block, 10 min after anesthesia, the patient initially exhibited increased heart rate and blood pressure, inability to swallow secretions (sputum), hoarseness, and dyspnea, then SpO2 decreased, the patient displayed contralateral eye movement disorder, reduced systemic muscle strength and other clinical manifestations. The condition was improved with the treatments for life support, and the surgery completed uneventfully under general anesthesia with tracheal intubation.
