Summary

Primary objective of this study is to find out the incidence of hemi-diaphragmatic palsy associated with interscalene block done under ultrasound guidance.

Primary hypothesis:

• There is an incidence of hemidiaphragmatic palsy ranging fron 33-100 % after an interscalene block.

Secondary hypothesis

* The incidence of hemidiaphragmatic palsy is much less than 33% when the block is done using ultrasound.
* The incidence of hemi-diaphragmatic palsy is directly proportional to volume of local anaesthetic injected.
* The incidence of hemi-diaphragmatic palsy is directly proportional to concentration of local anaesthetic injected.
