Ultrasound Guided Retroclavicular Infraclavicular Versus Axillary Block as Regional Anesthesia in Obese Patients

Ultrasound Guided Retroclavicular Infraclavicular Versus Axillary Block as Regional Anesthesia in Obese Patients Undergoing Around and Below Elbow Surgeries: A Randomized Clinical Study

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.

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.
