Clinical Efficacy of Supraclavicular Block for Arthroscopic Shoulder Surgery

N/ACompletedNCT01958801

Daegu Catholic University Medical Center104 enrolled

Overview

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

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.

Conditions

Horner's Syndrome

Interventions

Supraclavicular blockOTHER

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 blockOTHER

Outcomes

Primary Outcomes

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.

Time frame: 20 minutes after the end of local anesthetics injection

Secondary Outcomes

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).

Time frame: 20 minutes after the end of local anethetics injection

Side effects

Horner's syndrome (ptosis, miosis, anhidrosis) Subjective dyspnea Hoarseness

Time frame: 20 minutes after the end of local anethetics injection

Frequency of intraoperative analgesics or antihypertensives use

Frequency of intraoperative use of opioids (fentanyl) or antihypertensives (hydralazine)

Time frame: At the end of the surgery
