Design outcomes

Primary

Measure	Time frame
To compare the incidence of hemidiaphragmatic paresis after conventional volume with low volume Superior Trunk block in patients undergoing arthroscopic shoulder surgery as determined by diaphragmatic excursion using ultrasound.Timepoint: Pre op, 30 mins post block ,1hr Post Op	—

Secondary

Measure	Time frame
1. To compare the PFTs ( Pulmonary Function Tests) after conventional volume with low volume Superior Trunk block in patients undergoing arthroscopic shoulder surgery. 2. To compare the efficacy of postoperative analgesia provided by the different volumes of ropivacaine used in superior trunk block by NRS score. 3. To assess the duration of analgesia , intra op fentanyl consumption and total postoperative opioid consumption within the first 24 hours among the three groups.Timepoint: NRS pain scoring at 1hr,2hr,4hr & 24hr postoperative	—
