A new technique of sciatic nerve block in the popliteal fossa was evaluated in 120 patients using an 18 s.w.g. cannula. Precise placement of the cannula was facilitated with the aid of a nerve stimulator. In addition to an initial dose of 1% prilocaine with adrenaline 1: 200,000 (5 mg kg-1), 5 mL 0.5% bupivacaine was used for blockade of the saphenous nerve distal to the medial tibial condyle. One-third or one-quarter of the initial dose was administered when required for augmentation of anaesthesia or post-operative pain relief. Satisfactory anaesthesia was achieved in 117 patients (97.5%); two patients required general anaesthesia, since repositioning of the cannula after initial application of local anaesthetic was strictly avoided. No post-operative complications relating to the nerve block were observed. This technique of sciatic nerve block in the popliteal fossa provides effective and safe anaesthesia of the lower leg.
采用18号规格套管针，对120例患者的腘窝坐骨神经阻滞新技术进行了评估。借助神经刺激器便于套管针精确放置。除了给予初始剂量的含1:200,000肾上腺素的1%丙胺卡因（5mg/kg）外，还使用5ml 0.5%布比卡因阻滞胫骨内侧髁远端的隐神经。麻醉增强或术后镇痛需要时，给予初始剂量的三分之一或四分之一。117例患者（97.5%）获得了满意的麻醉效果；2例患者需要全身麻醉，因为在最初应用局部麻醉剂后严格避免了套管针重新定位。未观察到与神经阻滞相关的术后并发症。这种腘窝坐骨神经阻滞技术可为小腿提供有效且安全的麻醉。
