Brief Summary   This study is a prospective observational study comparing 6 ml and 10 ml of 0.5% Ropivacaine in Anterior Suprascapular nerve block in patients undergoing arthroscopic shoulder surgery. The primary objective of the study is to assess the diaphragm function following the block using ultrasonography and the secondary objective is to assess post operative pain score at 6 hours and 16 hours post operatively using numerical rating scale. Finding a phrenic sparing local anaesthetic volume with adequate post operative analgesia in anterior suprascapular nerve block achieves great relevance in patients with pulmonary compromise undergoing arthroscopic shoulder surgery. Identification of an adequate volume free of respiratory embarrassment as well as providing analgesia is the expected outcome of this study.
