Primary

Measure	Time frame
Comparison of perioperative analgesia efficacy and diaphragmatic function between interscalene block and superior trunk block, assessed by VAS score, ultrasound measurement of diaphragmatic excursion after block and changes in pulmonary function testTimepoint: Diaphragmatic function assessment - Baseline, 30mins post block, 4hrs post block VAS score - 1hr,2hrs,4hrs,6hrs,12hrs,24hrs	—

Secondary

Measure	Time frame
Onset & duration of sensory & motor blockade Patient satisfaction scoreTimepoint: Block onset time for sensory & motor blockade - assessed every 5mins upto 30mins after block Patient satisfaction score - at 24hrs postoperatively	—
