Two ultrasound-guided infraclavicular nerve block techniques for hand and forearm surgery
Comparison of Conventional and Retroclavicular Approaches for Ultrasound-guided Infraclavicular Brachial Plexus Block in Obese Patients
This study tests whether the retroclavicular or the conventional ultrasound-guided infraclavicular nerve block works better for adults with obesity having forearm or hand surgery.

What this trial studies
Adults aged 18–80 with BMI over 30 and ASA II–III who are scheduled for forearm or hand surgery receive an ultrasound-guided infraclavicular brachial plexus block using either the conventional or retroclavicular approach. The study compares how well each technique provides surgical anesthesia and postoperative analgesia while monitoring for procedure-related complications. Blocks are performed in the operating room under ultrasound guidance by experienced clinicians. The main focus is on effectiveness and safety of the two approaches in this obese patient population.
Who should consider this trial
Good fit: Adults 18–80 years old with ASA II–III, BMI >30, who are suitable for forearm or hand surgery under regional anesthesia are ideal candidates.
Not a fit: Patients who prefer or require general anesthesia, have contraindications to regional anesthesia, or cannot perceive and report pain are unlikely to benefit from participation.
Why it matters
Potential benefit: If successful, the preferred approach could provide better anesthesia and pain control with fewer complications for obese patients having forearm or hand surgery.
How similar studies have performed: Ultrasound-guided infraclavicular blocks are well established for upper-extremity surgery, while the retroclavicular approach is a newer technique with limited but promising data.
