The aim of this study was to investigate the use of ultrasound (US) guidance to perform sciatic and saphenous nerve blocks in dogs. Five dogs were sedated with medetomidine and butorphanol. A high-resolution US transducer was used to locate the nerves, guide placement of the needle and visualise the perineural injection of lidocaine 2%. Electrostimulation was used to confirm correct placement prior to the sciatic block. Nerve functions were evaluated over a 3 h period following administration of atipamezole. Successful identification of the nerves and the quality of the blocks were recorded. Location of the nerves, complete sensory block of the saphenous nerve, and partial to complete sensory and motor blocks of the sciatic nerve were achieved in all dogs. The resultant US guidance is potentially valuable for blocking the sciatic and saphenous nerves in dogs, although further work will be required to ensure a complete block of the sciatic nerve.
本研究旨在探讨在犬中使用超声（US）引导进行坐骨神经和隐神经阻滞的方法。五只犬用咪达唑仑和布托啡诺镇静。使用高分辨率 US 换能器定位神经，引导针的放置并可视化利多卡因 2%的神经周围注射。在进行坐骨神经阻滞之前，使用电刺激确认正确的位置。在给予阿替美唑后 3 小时内评估神经功能。记录神经的成功识别和阻滞的质量。在所有犬中均成功定位神经，并实现了隐神经的完全感觉阻滞，以及坐骨神经的部分至完全感觉和运动阻滞。尽管需要进一步的工作来确保坐骨神经的完全阻滞，但这种超声引导具有潜在的应用价值，可用于犬的坐骨神经和隐神经阻滞。
