Clinical Trial Summary

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

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.

Related Conditions & MeSH terms

• Horner Syndrome
• Horner's Syndrome

Intervention

Other:
• Supraclavicular block
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.
• Interscalene block
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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Degree of sensory blockade	Sensory blockade of the C5 to T1 dermatomes was assessed by rating the absence of cold sensation between 100 (intact sensation) and 0 (no sensation) with an alcohol swab.	20 minutes after the end of local anesthetics injection	No
Secondary	Degree of motor blockade	Motor blockade was evaluated by elbow and wrist extension (radial nerve), finger abduction (ulnar nerve), wrist flexion (median nerve), and elbow flexion (musculocutaneous nerve). The muscle force was rated on a scale of 0 to 6 as follows (6: normal muscle force; 5: slightly reduced muscle force; 4: greatly reduced muscle force; 3: slightly impaired mobility; 2: greatly impaired mobility; 1: near complete paralysis; 0: complete paralysis).	20 minutes after the end of local anethetics injection	No
Secondary	Side effects	Horner's syndrome (ptosis, miosis, anhidrosis) Subjective dyspnea Hoarseness	20 minutes after the end of local anethetics injection	No
Secondary	Frequency of intraoperative analgesics or antihypertensives use	Frequency of intraoperative use of opioids (fentanyl) or antihypertensives (hydralazine)	At the end of the surgery	No
