Costoclavicular versus lateral-sagittal infraclavicular block for hand and forearm surgery

Official title: Comparison Between Ultrasound-Guided Costoclavicular and Lateral-Sagittal Infraclavicular Brachial Plexus Blocks in Adult Distal Upper Limb Surgeries : A Randomized Controlled Trial

Run by Ain Shams University · NCT07517809 · Data updated 2026-11-12

This study will see if the costoclavicular ultrasound-guided brachial plexus block produces a faster onset of numbness and motor block than the lateral-sagittal infraclavicular block in adults having hand or forearm surgery.

Is this trial a fit for you?

Likely a good fit

Adults (ASA I–III) scheduled for distal upper limb surgery who can give written informed consent and have no pre-existing neuropathy, local infection, coagulopathy, severe pulmonary disease, allergy to study drugs, or BMI over 40 kg/m².

Probably not a fit

Patients with coagulopathy, active infection at the puncture site, severe pulmonary disease, pre-existing neurological deficit in the limb, allergy to the anesthetic drugs, or who refuse participation are unlikely to benefit from participation.

What this trial studies

This is a prospective randomized controlled comparison enrolling 50 adult patients undergoing distal upper limb surgery who receive one of two ultrasound-guided infraclavicular brachial plexus approaches. Participants are randomly assigned to a costoclavicular (CC) group or a lateral-sagittal infraclavicular (LS-ICB) group, with 25 patients per arm. Both groups receive the same local anesthetic mixture (2% lidocaine and 0.5% bupivacaine, 1:1 ratio) at 0.3 mL/kg under real-time ultrasound guidance. The primary outcome is time to onset of complete sensory and motor block, with safety and block quality monitored throughout.

Why it matters

Potential benefit: If successful, the costoclavicular approach could provide faster block onset and more efficient anesthesia for hand and forearm surgery, improving patient comfort and operating-room workflow.

How similar studies have gone: Small studies and case series have reported promising results for the costoclavicular approach with clustered cords and rapid anesthetic spread, but randomized comparisons remain limited.
