Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type ACTIVE_COMPARATOR

Interscalene block

Intervention Type PROCEDURE

Ultrasound-guided interscalene block is performed.

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.
