The authors have studied the anatomic peculiarities of the fascial case of the plexus in an experiment on 60 preparations of the brachial plexus as well as the ways of diffusion of the solution along the case making use of various methods of block. It has been shown that the fascial case forms a closed space determining the diffusion of the solution on a considerable way along the plexus. The main way of diffusion of the anaesthetic solution are the paravasal loose connective tissue structures. On the basis of the clinical application of this method in 85 patients the authors believe that the punction of the plexus case provides for a reliable and effective block and is characterized by safety and technical simplicity, which allows to recommend the case method for wide clinical use.
作者在对60例臂丛神经标本进行的实验中，研究了神经丛筋膜鞘的解剖学特点，以及利用各种阻滞方法使溶液沿鞘扩散的方式。结果表明，筋膜鞘形成一个封闭空间，在很大程度上决定了溶液沿神经丛的扩散。麻醉溶液扩散的主要途径是血管旁疏松结缔组织结构。基于该方法在85例患者中的临床应用，作者认为对神经丛鞘进行穿刺可实现可靠有效的阻滞，且具有安全性和技术操作简单的特点，因此推荐该鞘内阻滞法广泛应用于临床。
