100 participants in 2 patient groups

Supraclavicular approach group

Active Comparator group

Description:

probe placed firmly over the supraclavicular fossa, parallel to the clavicle to obtain a short-axis view of the divisions of the brachial plexus and the subclavian artery, lying on the first rib After skin infiltration with lidocaine 2% a 23-gauge 70mm block needle inserted in-plane with the ultrasound beam, in a lateral-to-medial direction, until the needle tip's positioned at the junction of the first rib and subclavian artery

Treatment:

Procedure: supraclavicular brachial plexus block

Retroclavicular approach group

Active Comparator group

Description:

the probe will be placed below and perpendicular to the clavicle, in a paramedian sagittal plane, medial to the coracoid process, to obtain a short-axis view of the cords of the brachial plexus and the axillary vessels. The needle will be then inserted in the supraclavicular fossa, approximately 1 cm posteriorly to the clavicle, and advanced in plane and strictly parallel to the ultrasound transducer. After passing the initial blind zone of about 2 cm caused by the acoustic shadow of the clavicle, the needle tip is constantly seen, until it is positioned posterior to the axillary artery

Treatment:

Procedure: Retroclavicular brachial plexus block
