Detailed Description

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

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.

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

Group Type ACTIVE_COMPARATOR

Interscalene block

Intervention Type OTHER

Redirection of the needle is allowed when spread of local anesthetics does not surround the brachial plexus appropriately and involuntary movement of the forearm or hand is not necessary to confirm the correct placement of the needle.

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

Group Type EXPERIMENTAL

Supraclavicular block

Intervention Type OTHER

Redirection of the needle is allowed when spread of local anesthetics does not surround the brachial plexus appropriately and involuntary movement of the forearm or hand is not necessary to confirm the correct placement of the needle.
