简要总结
This study is aims to compare between combined suprascapular and axillary nerve blocks versus interscalene nerve block regarding phrenic nerve affection assessed by ultrasound guided diaphragmatic excursion in shoulder arthroscopy surgeries.
详细描述
Interscalene approach of brachial plexus nerve block is recognized as the gold standard technique for postoperative pain control after shoulder arthroscopy surgeries . However, it is associated with major adverse effects and possibly critical complications including phrenic nerve affection. Combined suprascapular and axillary nerve blocks are considered to be a safe and effective alternative to interscalene nerve block for shoulder surgery. Futher studies had been done regarding postoperative analgesia after shoulder arthroscopy surgeries using intersalene nerve block versus suprascapular and axillary nerve blocks.
In this study, we will Compare between combined suprascapular and axillary nerve blocks vs interscalene nerve block regarding objective phrenic nerve affection known as a serious complication of interscalene nerve block.
