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.
Interventions
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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). |
| 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) |
