Comparison 1 Plane-2 Injection and 2 Plane-2 Injection Ultrasound-guided Supraclavicular Brachial Plexus Block

• Status: Completed
• Trial end date: 2015-12-01
• Target enrollment: 0
• Participant gender: All

Summary

The supraclavicular block can provide effective surgical anesthesia of the forearm and hand. There have been many different approaches to ultrasound-guided supraclavicular brachial plexus block (US-SCBPB) according to the needle injection site (e.g. corner pocket approach, cluster approach) or number of needling (single or double injection). Numerous studies demonstrates good results (e.g. faster onset time) when using double injections rather than single injection. But double injection does not guarantee complete sensory block because ulnar nerve tends to be spared by its anatomical location.
