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.
摘要: 球筋膜下麻醉技术 (Sub-Tenon’s block, STB) 是许多眼科手术优选的局部麻醉技术。STB风险相对较低, 威胁视力和生命的并发症极为罕见。在过去的三十年里, STB不断发展并广泛应用, 其改进技术包括使用不同类型的钝性金属注射管、塑料注射管以及 “无切口”的方法。STB在全球的应用差异很大。这篇叙述性文献综述回顾了STB技术的历史演变、解剖学和生理学相关理论依据、实用性及适用性、相关并发症, 并探讨了STB当前的应用及未来展望。.
