Supraclavicular Versus Interscalene Block

December 12, 2013 updated by: Cheju Halla General Hospital

A Randomized Comparison of Ultrasound-guided Supraclavicular and Interscalene Block After Shoulder Surgery

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

Status

Unknown

Conditions

Intervention / Treatment

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: 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.
Procedure: Interscalene block
Ultrasound-guided interscalene block is performed.
Experimental: 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.
Procedure: Supraclavicular block
Ultrasound-guided supraclavicular block is performed
