Pain Control After Arthroscopic Shoulder Surgeries

Comparative Study of Analgesic Efficacy of Ultrasound Guided Interscalene Block Versus Combined Shoulder Anterior Capsular Block and Suprascapular Nerve Block for Arthroscopic Shoulder Surgeries.

This study will be conducted to compare the perioperative analgesic efficacy of ultrasound - guided interscalene brachial plexus block versus combined shoulder anterior capsular block and anterior suprascapular nerve block for arthroscopic shoulder surgeries.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: group 1 Ultrasound-guided Interscalene Block group; In this group, ultrasound-guided ISB will be done using 10 ml of bupivacaine 0.25%.	Procedure: Ultrasound-guided Interscalene Block group; ultrasound guided interscalene block versus combined ultrasound guided shoulder anterior capsular block and suprascapular nerve block for arthroscopic shoulder surgery; Drug: Bupivacaine; bupivacaine 0.25%.
Active Comparator: group 2 Combined Ultrasound guided shoulder anterior capsular block and suprascapular nerve block; , ultrasound-guided SHAC block will be done using 10 ml of bupivacaine 0.25% injected in the interfacial plane between deltoid and subscapular muscle and 10 ml of bupivacaine 0.25% injected in the pericapsular space. Ultrasound-guided SSN block will be done using 10 ml of bupivacaine 0.25% injected at sub omohyoid space.	Drug: Bupivacaine; bupivacaine 0.25%.; Procedure: Combined Ultrasound guided shoulder anterior capsular block and suprascapular nerve block; Combined Ultrasound guided shoulder anterior capsular block and suprascapular nerve block

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
post operative analgesic consumption	The first 24 hours post operative analgesic consumption	24 hours after surgery

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Visual Analogue score (VAS) in the first 24 hours after surgery	- Postoperative pain intensity will be assessed in the first 24 hour using VAS score where (0 = no pain and 100 = the worst imaginable pain)	first 24 hours after surgery
Patient satisfaction score	Patient satisfaction score will be assessed on the basis of a questionnaire and graded on a 4-point scale (excellent/good/fair/poor).	first 24 hours after surgery
The incidence of hemi diaphragmatic paralysis	hemidiaphragmatic paralysis after block	immediately before block and immediately after procedure
