Comparison 1 Plane-1 Injection and 2 Plane-2 Injection Ultrasound-guided Supraclavicular Brachial Plexus Block

• Status: Completed
• Trial end date: 2015-09-01
• Target enrollment: 0
• Participant gender: All

Summary

Ultrasound-guided supraclavicular brachial plexus block (US-SCBPB) has been a generalized regional anesthesia in upper extremity surgery. It is performed just above the clavicle, in which the neural cluster formed by the trunks or divisions of the brachial plexus is situated superolateral to the subclavian artery (SA).

In many approaches, corner pocket approach [deposit local anesthetic (LA) at the intersection of the SA, neural cluster, and the first rib] and cluster approach (direct deposit LA into the neural cluster after penetration of the sheath of brachial plexus) has been well known methods. And single or multiple injection techniques has been used with the above approaches.
