背景：腓深神经是进行踝关节阻滞时麻醉的5条神经之一。已经描述了多种阻断腓深神经的技术，但几乎没有证据表明任何一种技术的有效性。我们假设，超声将增加成功率和质量的腓深神经阻滞在ankle.Methods：18名健康志愿者参加了这项随机，对照，前瞻性研究。每名受试者被随机分配接受右踝或左踝的超声引导下腓深神经阻滞。采用传统的标志技术阻断对侧腓深神经。受试者对所使用的技术不知情。所有组织块均用5 mL 3% 2-氯普鲁卡因预处理。我们评估了感觉和运动阻滞在10分钟的时间间隔为60 mins.Results：块在两组在20至30分钟最大。在10分钟时，温度感觉和运动功能存在统计学显著差异，有利于超声组。在20和60分钟之间，运动功能、温度或针刺感没有统计学差异。结论：超声的使用似乎可以改善踝部腓深神经阻滞的起效，但不能改善阻滞的整体质量，
Background: The deep peroneal nerve is I of 5 nerves anesthetized when performing an ankle block. Multiple techniques of blocking the deep peroneal nerve have been described, but little evidence exists to delineate the efficacy of any one technique. We hypothesized that ultrasound would increase both the success rate and the quality of a deep peroneal nerve block at the ankle.Methods: Eighteen healthy volunteers participated in this randomized, controlled, prospective study. Each Subject was randomly assigned to receive an ultrasound-guided deep peroneal nerve block of either the right or the left ankle. The deep peroneal nerve on the opposite side was blocked rising a conventional landmark technique. Subjects were blinded to the technique used. All blocks were preformed with 5 mL of 3% 2-chloroprocaine. We evaluated both sensory and motor blocks at 10-min intervals for 60 mins.Results: Blocks were maximal in both groups at 20 to 30 mins. There was a statistically significant difference in temperature sensation and motor function at 10 mins favoring the ultrasound group. There was no statistical difference in motor function, temperature, or pinprick sensation between 20 and 60 mins.Conclusions: The use of ultrasound seems to improve the onset of deep peroneal nerve block at the ankle but does riot improve the over-all quality of the block,
