Sub-Tenon's block (STB) is a good technique of local anaesthesia for many types of eye surgery. It has a relatively good risk profile, in that sight- and life-threatening complications appear to be extremely rare. STB has gained popularity in the last three decades, with refinements including different types of blunt metal cannula, plastic cannulae and 'incisionless' approaches. Usage of STB varies significantly across the globe. This narrative review documents the historical evolution of STB techniques, anatomical and physiological considerations, its utility and suitability, complications, explores the current practice and possible future applications.
球后阻滞(STB)是一种广泛应用于多种眼科手术的局部麻醉技术。它具有相对较好的风险特征,因为严重影响视力和危及生命的并发症极为罕见。STB 在过去三十年中得到了广泛应用,不断改进,包括不同类型的钝头金属套管、塑料套管和“无切口”方法。STB 的使用在全球范围内差异很大。本综述记录了 STB 技术的历史演变、解剖学和生理学考虑、它的效用和适用性、并发症,探讨了当前的实践和可能的未来应用。
