简要总结
The aim of this study is to compare the efficacy of supraclavicular and interscalene brachial plexus blocks in the patients undergoing arthroscopic shoulder surgery.
详细描述
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.

研究组 & 干预措施
Interscalene block
Interscalene block is performed under ultrasound guidance. Linear probe is placed on the ipsilateral interscalene groove visualizing the brachial plexus located between anterior and middle scalene muscles. Using in-plane technique, nerve stimulation needle is advanced into the brachial plexus sheath, into which 25 ml of 1.5% mepivacaine is injected.
干预措施: Interscalene block (Other)
Supraclavicular block
Supraclavicular block is performed under ultrasound guidance. Linear probe is placed on the ipsilateral supraclavicular fossa visualizing the brachial plexus located lateral to the subclavian artery. Using in-plane technique, nerve stimulation needle is advanced into the brachial plexus sheath, into which 25 ml of 1.5% mepivacaine is injected.
干预措施: Supraclavicular block (Other)
结局指标
主要结局
Degree of sensory blockade
时间窗: 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.
次要结局
- Side effects(20 minutes after the end of local anethetics injection)
- Frequency of intraoperative analgesics or antihypertensives use(At the end of the surgery)
- Degree of motor blockade(20 minutes after the end of local anethetics injection)
