Design outcomes

Primary

Measure	Time frame
To observe the difference in PI value between blocked and unblocked arms. To observe change in PI value before and after interscalene block in each arm. To calculate a cut off value of PI and PI ratio as predictors of successful block Timepoint: -baseline that is before the administration of block -after successful block (20 mins after administration of block)	—

Secondary

Measure	Time frame
To calculate a cut off value of PI and PI ratio as predictors of successful blockTimepoint: before start of surgery	—
