What this study is about

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.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.

Full registry criteria

Inclusion Criteria: * Patients acceptance to share in the study. * 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 a history of allergic reactions or contraindications to local anesthetics. * 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.

Treatments and study arms

retroclavicular infraclavicular brachial plexus block for

Other

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

Other

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
