Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Postoperative analgesia for shoulder surgery is typically achieved by providing an interscalene brachial plexus block. However, a very common side effect of this block is hemi-diaphragmatic paralysis, a state which may not be tolerated in patients with pulmonary conditions such as COPD.

Recently, clinicians have explored new ways to provide satisfactory analgesia while minimizing the pulmonary side effects of the interscalene nerve block. One of these solutions might be to offer the patient a suprascapular nerve block combined to costoclavicular block. Since these blocks are performed lower in the neck or under the clavicle, the phrenic nerve is less likely to be blocked. Thus, fewer respiratory side effects have been reported when using such blocks.

Hypothesis The main hypothesis of this study is that the addition of clonidine to suprascapular block combined with costoclavicular block is not inferior to the standard interscalene brachial plexus block in terms of postoperative analgesia. We postulate that pain score postoperatively and opioid requirements will not differ significantly in patients who receive either block.

Our secondary objectives will consist in looking at the differences in intraoperative , arm motor block , diaphragmatic paresis , patient satisfaction and time for readiness to discharge from PACU .we hypothesize that these outcomes will be similar in both groups , with the exception of a potential reduction in arm motor block and diaphragmatic paresis in the combined suprascapular and costoclavicular block group The primary objective of this study will be to evaluate the postoperative pain score during arthroscopic shoulder surgery assessed by the pain score when comparing the effect of addition of clonidine to suprascapular\_costoclavicular versus standard interscalene
