Ultrasound Guided Block for Postoperative Analgesia in Arthroscopic Shoulder Surgery

High Thoracic-ESPB The patient was placed in the lateral decubitus. The transverse process of T2 was identified. After negative aspiration, hydro dissection using 2 mL of saline was performed. Eventually, 30 mL of the LA bupivacaine 0.25% and epinephrine 5 µg/ mL was injected.

Shoulder Block Suprascapular nerve block (SSNB) approach: The needle was progressed in plane from medial to lateral after local infiltration of the skin with 1% lidocaine. We directed the needle towards the lateral side of the supra-spinous fossa if the neuro-vascular bundle was not evident. After careful aspiration, 10 ml of 0.5% bupivacaine was injected under the supraspinatus muscle. Axillary nerve block technique: The nerve approach had been described in plane from cranial to caudal. After local infiltration of the skin with 1% lidocaine, the needle tip must be visualized within the fascia below the teres minor muscle and just above the PCHA. After cautious aspiration, 10 ml of 0.5% bupivacaine was injected on the posterior aspect of the humerus.
