Three patients underwent foot surgery to correct hallux valgus and other toe deformities. Postoperative analgesia was provided by a sciatic nerve block in the popliteal fossa through a 21-gauge 64 mm needle and a 50 cm catheter connected to a nerve stimulator. Ropivacaine 0.125% was perfused continuously at a rate of 7 mL/h for 48 h. All 3 patients were very satisfied with the level of analgesia, given that the intensity of pain upon movement was never more than slight. Hallux valgus surgery causes intense postoperative pain that can be prevented by a peripheral nerve block. A continuous popliteal block through a catheter equipped with a nerve stimulator is an easy technique that provides very good pain management after this type of surgery, with few undesirable side effects.
三名患者接受了足部手术，以矫正拇外翻和其他脚趾畸形。通过一根21号64毫米的针头和一根连接神经刺激器的50厘米导管，在腘窝处进行坐骨神经阻滞，提供术后镇痛。0.125%的罗哌卡因以7毫升/小时的速度持续灌注48小时。所有3名患者对镇痛水平非常满意，因为运动时的疼痛强度从未超过轻微程度。拇外翻手术会导致剧烈的术后疼痛，而周围神经阻滞可以预防这种疼痛。通过配备神经刺激器的导管进行持续腘窝阻滞是一种简单的技术，在这类手术后能提供很好的疼痛管理，且不良副作用很少。
