GroupInterventionDescription
Supraclavicular approach groupsupraclavicular brachial plexus blockprobe 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
Retroclavicular approach groupRetroclavicular brachial plexus blockthe 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

Secondary Outcome Measures
NameTimeMethod
Duration of procedureone year

Time which took the investigator to administrate each type of block
