Ultrasound Guided Retroclavicular Infraclavicular Versus Axillary Block as Regional Anesthesia in Obese Patients
Sponsor: Zagazig University
Summary
The purpose of this study is to compare the analgesic outcomes (time to first analgesic request, total amount of analgesic consumption, and pain scores) following the ultrasound-guided retroclavicular infraclavicular approach and the axillary approach in obese patients.

Interventions
retroclavicular infraclavicular brachial plexus block for
The patient will be placed supine, head facing the contralateral side. A high- frequency 13-6 MHz linear array transducer probe will be placed medial to the coracoid process below and perpendicular to the clavicle to obtain a short-axis view of the cords of the brachial plexus and the axillary vessels. The needle will be inserted in the supraclavicular fossa, approximately one cm posteriorly to the clavicle, and advanced in plane parallel to the probe. After passing the initial blind zone of about 2 cm caused by the clavicle's acoustic shadow, the needle tip will be continuously seen, until it appears posterior to the axillary artery. A single injection of the local an esthetic will be performed without needle repositioning unless paresthesia is elicited
axillary block
The axillary nerve block is performed from behind the patient with the patient seated. The axillary nerve will be identified within the quadrilateral space by placing high frequency linear probe parallel to the long axis of the humeral shaft. The nerve was identified next to the circumflex artery
