Clinical Trial Summary

For ultrasound guided intermediate cervical plexus block this randomized comparison is testing the hypothesis, that an additional perivascular infiltration is associated with increased block quality.


Clinical Trial Description

The innervation of the neck is complex and involves the cervical and the brachial plexus as well as cranial nerves. So is the wall of the carotid arteries innervated by vagal and glossopharyngeal nerve as well as the sympathetic trunk. When carotid surgery was performed under regional anesthesia, so additional infiltration of local anesthetic by the surgeon was common, particularly during preparation of the carotid arteries.

Introduction of ultrasound guidance made it possible to guide the needle directly to the vascular wall. But this procedure is considered very demanding, because of guiding the needle in an anatomical region with artifacts (because of calcification), sudden movements (e.g. because of swallowing) and compromised coagulation (antithrombotic medication). On the other side there are no clinical data proving the benefit of an additional perivascular infiltration with local anesthetic. Therefore, this investigation is testing the hypothesis, that an additional perivascular infiltration is associated with increased block quality. ;
