Design outcomes

Primary

Measure	Time frame
Te test the hypothesis that a local anesthetic volume of 20ml injected extrafascially would reduce rate of hemidiaphragmatic paralysis vs intrafascial intrascalene brachial plexus block.Timepoint: 15 minutes and 30 minutes post operatively	—

Secondary

Measure	Time frame
To assess quality of block with extrafascial approach versus intrafascial approach.Timepoint: 15 minutes & 30 minutes post operatively	—
