About

The aim of this study is to compare the efficacy of supraclavicular and interscalene brachial plexus blocks in the patients undergoing arthroscopic shoulder surgery.

Full description

This study aims to compare supraclavicular brachial plexus block to interscalene brachial plexus block with regard to degree of sensory and motor blockades, side effects and complications of the blocks, and frequency of intraoperative analgesics or antihypertensives use.

Sex: All

Ages: 15 to 80 years old

Trial design

104 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, nerve stimulation needle is advanced into the brachial plexus sheath, into which 25 ml of 1.5% mepivacaine is injected.

Treatment:

Other: 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, nerve stimulation needle is advanced into the brachial plexus sheath, into which 25 ml of 1.5% mepivacaine is injected.

Treatment:

Other: Supraclavicular block
