Effectiveness of Interscalene Brachial Plexus Block and Intra-articular Injection of Ropivacaine for Post-operative Analgesia in Arthroscopic Shoulder Stabilization Surgery

Not Applicable

• Conditions: Postoperative Analgesia
• Interventions: Procedure: Intra-articular Ropivacaine injection; Procedure: Interscalene brachial plexus block; Device: Ultrasound guided technique; Drug: Ropivacaine

• Registration Number: NCT01589354
• Lead Sponsor: NHS Grampian

Brief Summary

This study evaluates two anaesthetic techniques namely interscalene brachial plexus block and intra-articular local anaesthetic injection.
