About

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

Full 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.

50 participants in 2 patient groups

Interscalene block

Active Comparator group

Description:

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.

Treatment:

Procedure: Interscalene block

Supraclavicular block

Experimental group

Description:

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.

Treatment:

Procedure: Supraclavicular block
