In this study the investigators aim to compare the effect of the suprascapular- supraclavicular nerve block in association with dexamethasone to that of the interscalene brachial plexus block on analgesic effect during arthroscopic shoulder surgery, as postoperative pain scores ,postoperative consumption of analgesic rescue medications and diaphragmatic excursion assessment.
ASA status 1,2.
Age 18 years or older
Elective shoulder arthroscopic surgery under general anesthesia and nerve block performed preoperatively.
• Patient refusal
Serious cardiac arrhythmias (including atrial fibrillation) or unstable coronary artery disease.
Use of drugs that act on the autonomic nervous system (including β- blockers).
Coagulation disorders..
Parallel
Shoulder arthroscopy blocks
Procedure/SurgeryEffect of dexamethasone adjuvant in combined supraclavicular block and suprascapular block versus Interscalene block in patients undergoing shoulder arthroscopy.
Postoperative analgesia by visual analog scale (VAS).
The primary outcome of this study will be to evaluate and compare between suprascapular-supraclavicular nerve block in association with dexamethasone to that of the interscalene brachial plexus block on postoperative analgesia by vas score during 48h postoperatively ( 2h , 6h , 12h, 24h and 48h). The VAS consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be').
Diaphragmatic excursion
Assessment of diaphragmatic excursion by ultrasound preoperatively and 1hour postoperatively
