Design outcomes

Primary

Measure	Time frame
To evaluate the analgesic efficacy of ISB versus A-SSB versus STB in patients undergoing elective arthroscopic shoulder surgery under GA , in terms of the duration of analgesia ( assessed as time to demand for first analgesic after LA administration).Timepoint: 0, 1, 2, 4, 6, 12 and 24 hours after surgery.	—

Secondary

Measure	Time frame
Secondary Objectives: 1. To evaluate analgesic efficacy of ISB versus A-SSB versus STB as assessed by NRS scores. 2. To evaluate total dose of additional analgesic consumed during intraoperative period & 24 hr postoperative period. 3. To note the incidence of side-effects (PONV, HDP, hypotension & bradycardia) in the 3 study groups (group I, Group A & Group S).Timepoint: 0, 1,2,4,6,12 & 24 hours after surgery.	—
