Effect of Dexamethasone Adjuvant in Combined Supraclavicular Block and Suprascapular Block Versus Interscalene Block in Patients Undergoing Shoulder Arthroscopy

Not Applicable

Recruiting

• Conditions: Shoulder Arthroscopy Blocks; Dexamethasone
• Interventions: Procedure: Shoulder arthroscopy blocks

• Registration Number: NCT06262893
• Lead Sponsor: Assiut University

Brief Summary

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.

Primary Outcome Measures

Name	Time	Method
Postoperative analgesia by visual analog scale (VAS).	48 hours	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').

Secondary Outcome Measures

Name	Time	Method
Diaphragmatic excursion	1hour postoperatively	Assessment of diaphragmatic excursion by ultrasound preoperatively and 1hour postoperatively
