Study Comparing Two Ultrasound-Guided Brachial Plexus Block Techniques for Adult Distal Upper Limb Surgeries

What this Trial Is About

Researchers are comparing two ultrasound-guided techniques for brachial plexus block used in adults undergoing distal upper limb surgeries. The study aims to evaluate the time it takes for the anesthesia to start working between the newer costoclavicular approach and the traditional lateral-sagittal infraclavicular approach. This research may help identify the most effective and safe method for regional anesthesia in these surgeries. Participants will be randomly assigned to receive either the costoclavicular brachial plexus block or the lateral-sagittal infraclavicular brachial plexus block. Both procedures involve injecting a mixture of 2% lidocaine and 0.5% bupivacaine in a 11 ratio, with a total volume of 0.3 mLkg, guided by real-time ultrasound. The blocks are performed using a high-frequency linear ultrasound probe to target the cords of the brachial plexus. During the study, researchers will assess the time until full sensory and motor block occurs, with sensory block evaluated by pinprick tests on specific nerves. Additional measurements include block performance time, success rate, complications, postoperative pain scores, and analgesic use in the first 24 hours after surgery. Safety and effectiveness are monitored throughout, and the study is expected to conclude in September 2026.
