is There an Alternative to Ultrasound Guided Interscalene Block?

Not Applicable

• Conditions: Shoulder Surgery; Regional Anesthesia; Interscalene Block
• Interventions: Drug: bupivacaine; Device: ultrasound; Drug: morphine

• Registration Number: NCT02397330
• Lead Sponsor: Tunisian Military Hospital

Brief Summary

Interscalene brachial plexus block is the gold standard for perioperative pain management in shoulder surgery. However, this technique would have side effects and potential serious complications. The aim of this study is to compare between the combination of ultrasound guided suprascapular and supraclavicular nerve blocks versus ultrasound guided interscalene brachial plexus block for post operative analgesia after shoulder instability surgery with latarjet procedure.
