Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Advances in modern arthroscopy have contributed significantly to greater flexibility and efficacy in addressing shoulder pathology.Advantages of arthroscopy include less invasive approaches, improved visualization, decreased risk of many postoperative complications ,and faster recovery.
Shoulder surgery is well recognised as having the potential to cause severe postoperative pain.The aim of this review is to assess critically the evidence relating to the effectiveness of regional anaesthesia techniques commonly used for postoperative analgesia following shoulder surgery opioid analgesics are commonly used for analgesia when nerve block are not used. opoids are effective in relieving postoperative pain at rest but may increase postoperative nausea and vomiting (PONV),somnolence,constipation,urinary retention,respiratory depression ,and sleep disturbances.
supplementing general anesthesia (GA) with a regional nerve block might improve the quality of postoperative relief pain .
Throughout intraoperative and postoperative period, nerve blocks have been used more populary than others because of efficacy.For the regional nerve block,local anesthetic should be infiltrated close to the nerve for maximum effect.
Shoulder anterior capsule block (SHAC):is combination of two different blocks .the first block is the interfascial space between the deep layer of the deltoid fascia and the superficial layer of the subscapularis fascia , anterior to the subscapularis myotendinous junction . Thanks to this interfascial space,we can reach both the axillary nerve and the subscapular nerves,the lateral pectoral nerve and the musculocutaneous nerve.
Suprascapular nerve block(SSB) :The suprascabular nerve (SSN) originates from the nerve roots and provides sensation for the posterior shoulder capsule, acromioclavicular joint,subacromial bursa,and coracoclavicular ligament .Blocking it provides pre-emptive anesthesia , decreased intraoperative pain ,and postoperative pain relief in shoulder arthroscopy.

RANDOMIZED
PARALLEL
For suprascapular nerve block :
Patients will be placed in lateral position until supraspinatus or infraspinatus muscle contractions were elicited. Following negative aspiration,A 21G 10-cm needle will be inserted using an in-plane approach .The tip of the needle will be placed at the floor of the supraspinatus fossa where the nerve has passed .A volume of 15 mL of a mixture of 2% lidocaine (5 mL) and 0.5% levobupivacaine (10 mL) was injected.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
SHAC block group
For the SHAC block, with the patient in a beach-chair position and with the arm in extension, the subscapularis muscle is stretched posteriorly and becomes easily visible. With external rotation and abduction, the coracobrachialis and the biceps brachii muscles are displaced, allowing the visualization of the interfascial space between the deep lamina of the deltoid muscle fascia and the superficial lamina of the subscapularis fascia.Once the injection into the fascial space is achieved, the investigators can proceed towards the glenohumeral pericapsular space by crossing the subscapularis muscle with the needle. By injecting the pericapsular space, the investigators reach the terminal articular branches indistinctly from their origin. Furthermore, through the Weitbrecht foramen, a natural capsular foramen between the upper and middle glenohumeral ligaments, we also reach the intra-articular space .

Suprascapular nerve block group
Patients will be placed in lateral position by using A high - frequency linear ultrasound probe will be placed approximately 2 cm medial to the medial border of the acromion and about 2 cm cranial to the superior margin of the scapular spine until supraspinatus or infraspinatus muscle contractions were elicited. Following negative aspiration,A 21G 10-cm needle will be inserted using an in-plane approach .The tip of the needle will be placed at the floor of the supraspinatus fossa where the nerve has passed .A volume of 15 mL of a mixture of 2% lidocaine (5 mL) and 0.5% levobupivacaine (10 mL) was injected.
