Clinical Efficacy of Supraclavicular Block for Arthroscopic Shoulder Surgery

Not Applicable

Completed

• Conditions: Horner's Syndrome

• Registration Number: NCT01958801
• Lead Sponsor: Daegu Catholic University Medical Center

Brief 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.

Detailed 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.

Primary Outcome Measures

Name	Time	Method
Degree of sensory blockade	20 minutes after the end of local anesthetics injection	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.

Secondary Outcome Measures

Name	Time	Method
Side effects	20 minutes after the end of local anethetics injection	Horner's syndrome (ptosis, miosis, anhidrosis) Subjective dyspnea Hoarseness
Frequency of intraoperative analgesics or antihypertensives use	At the end of the surgery	Frequency of intraoperative use of opioids (fentanyl) or antihypertensives (hydralazine)
Degree of motor blockade	20 minutes after the end of local anethetics injection	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).
