Summary

The aim of the study is to compare the post-operative analgesic effect of Shoulder anterior capsule (SHAC) block with Suprascapular nerve block for arthroscopic shoulder surgery with a hypothesis that both Shoulder anterior capsule (SHAC) block and Suprascapular nerve block are effective in providing postoperative analgesia for arthroscopic shoulder surgery.

Conditions

  • Shoulder Pain
  • Postoperative Pain

Interventions

PROCEDURE

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, the investigators also reach the intra-articular space .

PROCEDURE

suprascapular nerve block

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.
