杜克大学 | 超声引导收肌管阻滞要点提炼(中英文双语对照)
引言曾经,收肌管阻滞的主要目标是隐神经,并通过局麻药在收肌管内扩散,阻滞其他神经包括闭孔神经分支,股内侧肌支,甚至坐骨神经。但事实真的如此么?还是另有隐情?本期视频为我们揭示这样一个收肌管阻滞的细节。https://www.bilibili.com/video/BV1Xa411z7jf?share_source=copy_web杜克大学超声引导收肌管阻滞技术(中英文双语对照)

图1. 大腿中段神经解剖
At the mid thigh, this nerve has become primarily an articular nerve, innervating the anterior medial joint capsule.在大腿中段,该神经成为主要支配前内侧关节囊的关节神经。
图2.You can see here that the nerve to vastus medialis contributes significantly to the anterior medial joint capsule, while the saphenous nerve only supplies a few twigs.在此处可以发现,分布于前内侧关节囊的神经主要来自于股内侧肌支神经,很少一部分来自于隐神经。
图3.The adductor membrane stretches from the medial vastus muscle to the abductor group, separating the nerve to vastus medialis in the mid thigh from the saphenous nerve in most patients.在大多数患者中,股收肌膜从股内侧肌延伸到外展肌群,并且,在大腿中段,将股内侧肌支神经和隐神经分开。
图4.Here we see two hyperechoic structures, the one on the left is the saphenous, the one on the right could be nerve devices, but it could also just be an artifact. 这里,我们看到两个高回声结构,左边这个是隐神经,右边这个可能是神经,但也可能只是伪影。
图5.With adductor canal catheters we take care to ensure that spread through the multi-orifice catheter is spreading into both compartments to maximize efficacy.在收肌管留置导管时,我们要注意通过多孔导管,确保局麻药扩散到两个筋膜室中,以最大限度地提高阻滞效果。
图6.In summary, both the nerve to vastus medialis and the saphenous play a central role in the efficacy of the adductor canal block. These nerves are separated in many patients by the vastoadductor membrane. And oftentimes, the nerve to vastus is difficult to see. Nerve stimulation is easy and effective, in order to identify the nerve to protect it and to make sure it's blocked. Finally, make sure you get local anesthetic in both compartments to reduce the chance of a failed vastus medialis nerve block.
总之,股内侧肌支神经和隐神经在收肌管阻滞的中都起着重要作用,在很多患者中,这些神经被宽大的股收肌膜隔开。通常情况下,股肌支神经很难被看到,神经刺激仪可以方便且有效地识别神经,避免神经损伤,并确保神经阻滞成功。最后,尽量做到在两个筋膜室都注射局麻药,以减少股内侧肌支神经阻滞失败的可能性。
