Supraclavicular Versus Interscalene Block

Not Applicable

• Conditions: Pain
• Interventions: Procedure: Interscalene block; Procedure: Supraclavicular block

• Registration Number: NCT02014766
• Lead Sponsor: Cheju Halla General Hospital

Brief Summary

We hypothesize that both ultrasound-guided supraclavicular and interscalene block provide similar analgesia after shoulder surgery.

Detailed Description

Interscalene block provides effective postoperative analgesia after shoulder surgery. However, it can be associated with significant risk including the phrenic nerve palsy. Previous study reported that ultrasound-guided interscalene and supraclavicular blocks are effective and safe for shoulder arthroscopy.

Arm && Interventions

Group	Intervention	Description
Interscalene block	Interscalene block	Interscalene block is performed under ultrasound guidance. Linear probe is placed on the ipsilateral interscalene groove visualizing the brachial plexus located between anterior and middle scalene muscles. Using in-plane technique, an insulated needle is advanced into the brachial plexus sheath, into which 20 ml of 0.375% ropivacaine is injected.
Supraclavicular block	Supraclavicular block	Supraclavicular block is performed under ultrasound guidance. Linear probe is placed on the ipsilateral supraclavicular fossa visualizing the brachial plexus located lateral to the subclavian artery. Using in-plane technique, an insulated needle is advanced into the brachial plexus sheath, into which 20 ml of 0.375% ropivacaine is injected.
