Summary

Recently, the Combined suprascapular nerve block and axillary nerve block (SSNB+ANB) was proposed to provide anesthesia and postoperative analgesia for shoulder surgery as a safe alternative to interscalene block. These two peripheral nerves are responsible for the majority of the sensory innervation of the shoulder.

PENG block has been studied extensively in hip surgeries, but its place in shoulder surgeries is not yet clear. It is a new technology reported for block of articular branches of the shoulder and well pericapsular spread around the glenohumeral joint Therefore, achieving pain relief while avoiding motor block allows us not only to provide an early rehabilitation program in the postoperative period, but also to control the chronic nociceptive activation secondary to pain-induced movement

Conditions

  • Post Operative Pain

Interventions

PROCEDURE

ultrasound guided pericapsular nerve group shoulder block

The patient's arm is placed in external rotation and abducted at 45 degrees. A linear ultrasound probe will be placed longitudinally between the coracoid and the humeral head. After defining the humeral head, the tendon of the subscapular muscle and the deltoid muscle over it, a 50-mm needle will be inserted using the ''in plane'' technique. When the needle pass through the deltoid muscle and touched the subscapularis tendon, a bone-like hard tissue will be felt and the needle could not be advanced further. The needle tip will be placed between the deltoid muscle and subscapularis tendon, and 20 cc of 0.25% bupivacaine hydrochloride with 4mg dexamesathone will be injected

PROCEDURE

ultrasound guided suprascapular and axillary nerve block

The patient will be positioned in a semi-recumbent position with the operating arm on the contralateral shoulder. The probe will be kept over the scapular spine to identify the trapezius and the supraspinatus muscle. Then, it will be moved laterally to identify the concavity of the supraspinatus fossa and the hyper-echoic fascia of the supraspinatus muscle. In the concavity of the fossa, the suprascapular artery and the suprascapular nerve run in close proximity. 10 ml of 0.25% bupivacaine with 2mg dexamethasone will be injected below the supraspinatous fascia then the posterior surface of the humerus will be visualised in the short axis view. So, the AN and posterior circumflex artery will be visualised longitudinally. 10 ml of 0.25% bupivacaine with 2mg dexamethasone will be injected into space
