The role of ultrasound scanning in spinal anesthesia is principally limited to preprocedure imaging and identification of anatomical structures. We describe our experience with a real-time ultrasound technique for visualization and performance of spinal anesthesia. An initial cadaver study was performed in 5 unembalmed cadavers to develop a technique for real-time performance of ultrasound-guided spinal anesthesia via Taylor's approach (paramedian approach to the L5-S1 interspace). Subsequently, 10 patients scheduled for joint arthroplasty underwent real-time ultrasound-guided spinal anesthesia in the prone position. The relevant anatomy and the needletip were visualized easily and all spinals were effective for joint arthroplasty.
超声扫描在脊髓麻醉中的作用主要限于术前成像和解剖结构的识别。我们介绍了一种实时超声技术，用于可视化和进行脊髓麻醉。最初在 5 具未经防腐处理的尸体上进行了一项尸体研究，以开发通过 Taylor 入路（L5-S1 椎间的正中入路）实时进行超声引导脊髓麻醉的技术。随后，10 名计划进行关节置换术的患者在俯卧位接受了实时超声引导下的脊髓麻醉。相关的解剖结构和针尖很容易被可视化，所有的脊髓麻醉都对关节置换术有效。
