Evaluating the Analgesic Efficacy of Combined Individual Nerve Block in Comparison to Interscalene 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 will be injected

"the patient will be put in the sitting position, linear 38-mm high frequency 10-12 MHz transducer will be placed first on the scapula to view of the suprascapular nerve. 5-8 mL of 0.25% bupivacaine is injected to block the SSN.~The ultrasound probe put on the posterior aspect of the shoulder to view the circumflex artery, 10 mL of 0.25% bupivacaine this will lead to loss of sensation over the deltoid.lateral pectoral nerve block (LPNB) will be done by injecting a volume of 8 ml of a 0.25% bupivacaine The probe will be moved towards the biceps muscle until the musculocutaneous nerve is seen and 8 ml of 0.25% bupivacaine will be injected."
