Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Incidence of Hemidiaphragmatic Paralysis (HDP)	Our primary outcome will be the incidence of hemidiaphragmatic paralysis (HDP) with superior trunk block and interscalene blocks as measured by ultrasound before and after the surgery.	Day of Surgery, diagnosis confirmed from trained anesthesiologist ultrasound readers
Primary	Numerical Pain Rating System (NRS) Pain Scores	Numerical Pain Rating System Pain scores after the superior trunk block and interscalene block at rest measured after the surgery every 30 minute until discharge according to the Post Anaesthetic Discharge Scoring System.; Numerical Rating Scale 0-10; with 0 being no pain and 10 pain as bad as you can imagine.	Average pain scores at rest recorded Day of Surgery every 30 minutes until discharge according to Post Anaesthetic Discharge Scoring System
Secondary	Block Duration	Length of nerve block reported by Phone call on POD 1 and POD 2 by patient phone call	Time of block wearing off recorded on Post Operative Day 1 and Post Operative Day 2 as reported via patient phone call.
