Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Supraclavicular approach group

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

Group Type ACTIVE_COMPARATOR

supraclavicular brachial plexus block

Intervention Type PROCEDURE

group will receive brachial plexus block above clavicle,Injection of anaesthetic will be done in brachial plexus around subclavian artery

Retroclavicular approach group

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

Group Type ACTIVE_COMPARATOR

Retroclavicular brachial plexus block

Intervention Type PROCEDURE

group will receive brachial plexus block inferior to the clavicle,injection of anaesthetic will be done around axillary artery
