About this study

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.

Treatment and study plan

Supraclavicular block

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.

Interscalene block

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.

Primary outcomes

  1. 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.

Secondary outcomes

  1. 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).

  2. Side effects

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

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

  3. 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)
