Active Comparator
Active Comparator
group A: receive ultrasound-guided interscalene block
group B: receive ultrasound-guided selective nerve block
The patient will be put in the supine position, with the arm adducted a high-frequency linear ultrasound probe is oriented transversely across the lateral neck. When visualizing the ''stoplight sign,''15 to 30 mL of 0.25% bupivacaine consistent with the overall local anaesthetic dosing of less than 2.5 mg/kg. will be injected with low pressures to avoid intraneural injection.
The patient will be put in the sitting position, a linear 38-mm high frequency 10-12 MHz transducer will be placed first on the scapula to obtain a view of the suprascapular nerve a 22 G, 8 cm needle will be advanced in-plane and a total of 5-8 mL of 0.25% bupivacaine is injected then the arm adducted the linear probe will be placed at the junction of the pectoralis major muscle and the biceps muscle such that the axillary artery will be visualized in cross-section The probe will be moved towards the biceps muscle (laterally) until the musculocutaneous nerve is visualized and8 ml of 0.25% bupivacaine will be injected
