Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group (R)
Patients will recieve retroclavicular infraclavicular brachial plexus block
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
Group (A)
Patients will receive the axillary brachial plexus
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

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Patients with ASA physical status I-II.
* Obese patients (BMI 30-40 kg/m²) undergoing around and below elbow surgeries under regional anesthesia.
* Patients requiring a single injection infraclavicular retroclavicular brachial plexus block or axillary block for around and below elbow surgeries.
Exclusion Criteria
* Patients with significant comorbidities (e.g., severe cardiovascular, neurological, or musculoskeletal disorders).
* Patients with a history of previous shoulder or clavicle surgery that may distort anatomy and affect the efficacy of the block.
* Pregnant or breastfeeding women.
* Patients with a history of systemic infections or skin infections in the area of the block.
