PURPOSE
To evaluate the effectiveness of localized sub-Tenon's anesthesia for pain control during 23-gauge vitreoretinal surgery.
METHODS
Eighty patients were randomly divided into two groups as localized sub-Tenon's (group 1, n = 41) and retrobulbar (group 2, n = 39) anesthesia groups. In group 1, a small volume of anesthetic was injected into the sub-Tenon's capsules at the trocar entry sites. The 23-gauge vitreoretinal surgery was performed in all patients. In both groups, the pain levels during the surgical steps were evaluated using the visual analog pain scale.
RESULTS
Patients in group 1 experienced less pain than group 2 patients did during placement of the trocars and scleral depression (p = 0.041, p = 0.029). Pain during laser photocoagulation was higher in group 1 (p = 0.008). There was no serious complication due to anesthesia or surgery.
CONCLUSION
Localized sub-Tenon's anesthesia is as effective as retrobulbar anesthesia in many steps of vitreoretinal surgery for providing pain control. It can be considered an alternative form of local anesthesia.
目的
评估局部眼筋膜下麻醉在 23G 玻璃体视网膜手术中控制疼痛的效果。
方法
将 80 例患者随机分为局部眼筋膜下麻醉组（1 组，n=41）和球后麻醉组（2 组，n=39）。1 组在套管入口处的眼筋膜下囊内注射小体积麻醉剂。所有患者均行 23G 玻璃体视网膜手术。两组患者均采用视觉模拟疼痛量表评估手术各步骤的疼痛程度。
结果
在套管放置和巩膜压迫时，1 组患者的疼痛程度低于 2 组（p=0.041，p=0.029）。1 组患者在激光光凝时的疼痛程度更高（p=0.008）。麻醉或手术无严重并发症。
结论
在玻璃体视网膜手术的许多步骤中，局部眼筋膜下麻醉与球后麻醉一样有效，可控制疼痛。它可以被认为是局部麻醉的一种替代形式。
