• Interscalene blockA vizsgált kezelés

  Under sterile precautions, a high frequency linear array transducer \[6-13 Megahertz (MHz), Sonosite M-Turbo\] probe will be placed in the transverse plane over the interscalene groove to visualize the carotid artery and the C5 and C6 nerve roots of the brachial plexus between the anterior and middle scalene muscles. A 5 cm 22 G insulated needle will then be inserted in line with the US probe in a lateral-to-medial approach until the needle tip is adjacent to the C5 and C6 roots. After negative aspiration for blood, 15 mL ropivacaine 0.5% will be injected in 5 mL aliquots in order to achieve spread adjacent to C5 and C6 nerve roots.

• Superior Trunk Nerve blockMár használt kezelés, összehasonlításként

  Under sterile precautions, a high frequency linear array transducer \[6-13 Megahertz (MHz), Sonosite M-Turbo\] probe will be placed in the transverse plane over the interscalene groove to visualize the carotid artery and the C5 and C6 nerve roots of the brachial plexus between the anterior and middle scalene muscles. The superior trunk will be identified by tracing the C5 and C6 nerve roots caudally towards the supraclavicular fossa on the anterior lateral portion of the neck. A 5 cm 22 G insulated needle will then be inserted in line with the US probe in a lateral-to-medial approach until the needle tip is properly positioned. After negative aspiration for blood, 15 mL ropivacaine 0.5% will be injected in 5 mL aliquots.
