简要总结
We hypothesize that both ultrasound-guided supraclavicular and interscalene block provide similar analgesia after shoulder surgery.
详细描述
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.

研究组 & 干预措施
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.
干预措施: Interscalene block (Procedure)
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.
干预措施: Supraclavicular block (Procedure)
