Numerical Pain Rating System (NRS) Pain ScoresPrimary· Average pain scores at rest recorded Day of Surgery every 30 minutes until discharge according to Post Anaesthetic Discharge Scoring System
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.
