USG Brachial Plexus Block for Upper Extremity Surgery

Carpal Tunnel Syndrome Clinical Trial

Official title: Ultrasound-guided Brachial Plexus Block With the Single-penetration Multiple-injection-technique for Upper Extremity Surgery

Status Completed

Clinical Trial Summary

Ultrasound-guided (USG) brachial plexus (BP) block efficacy at the Supraclavicular (SCL), Lateral- Infraclavicular (LIC) and Axillary (AX) level: Randomized, observer-blinded study of the single-penetration multiple-injection-technique.

Clinical Trial Description

The investigators will compare the BP block efficacy (for surgical anaesthesia) with the USG single-penetration multiple-injection-technique at the SCL, LIC and AX level for upper-extremity surgery (elbow, forearm, wrist, hand). The investigators want to investigate whether the single-penetration multiple-injection-technique would provide for safe surgical anaesthesia with lower volumes of local anaesthetics than has previously been described in a comparative study at the three different levels.

120 patients will prospectively be randomized to an USG BP block administered as a single-penetration multiple-injection-technique at one of three different levels: (1) SCL (2) LIC (3) AX. Ropivacaine 0.75% (20 mL) will be used for all blocks prior to surgery. ;
