Clinical Trial: Clinical Efficacy of Supraclavicular Block for Arthroscopic Shoulder Surgery

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title: Comparison Between Ultrasound-guided Supraclavicular and Interscalene Brachial Plexus Blocks in the Patients Undergoing Arthroscopic Shoulder Surgery

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 Summary: 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.
Sponsor: Daegu Catholic University Medical Center

Current Primary Outcome: Degree of sensory blockade [ Time Frame: 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.


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Degree of motor blockade [ Time Frame: 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).
  • Side effects [ Time Frame: 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 [ Time Frame: At the end of the surgery ]
    Frequency of intraoperative use of opioids (fentanyl) or antihypertensives (hydralazine)


Original Secondary Outcome: Same as current
