Brief Summary

supraclavicular brachial plexus block is one of the common technique of anaesthesia for upper limb surgeries.One of the common adverse effect of supraclavicular brachial plexus block is ipsilateral hemidiaphragmatic paresis.

hfew studies have shown lower incidence of ipsilateral hemidiaphtrgamatic paresis (11.4%) following supraclavicular block,but the data is still insufficient,hence this study is planned to compare the incidence of ipsilateral hemidiphragmatic paresis between the supraclavicular and costoclavicular approach to brachial plexus block

It is a prospective,double blinded,randomised control trial,which has a primary objective to compare the incidence of hemidiaphragmatic paresis after supraclavicular nd infraclavicular block and secondary objective is to see the onset and duration and quality of sensory and motor block.we are recruting sample size of 60 ,30 in each group,satisfying all the inclusion criterias.GROUP A-Supraclavicular block with 30ml of 0.5% ropivacaine and GROUP B-Costoclavicular block with 30ml of 0.5% ropivacaine.

primary outcome will be measured by 1)M mode ultrasound to see the diaphragmatic excursion after 30 minutes and peak expiratory flow rate after the block post operatively

Primary Outcome Measures

Name	Time	Method
Incidence of Hemidiaphragmatic paralysis by M mode ultrasound,and measuring diaphragmatic excursion and peak expiratory flow rate	M mode ultrasound at 10 minutes interval after complete motor block and PEFR at 10 minutes interval

Secondary Outcome Measures

Name	Time	Method
Onset, duration and quality of blockade.	At 15-30 minutes we assess sensory blockade in the Musculocutaneous(lateral forearm),radial(dorsal hand),median(thenar eminence) and ulnar(hypothenar eminence) distributions with respect to temperature, pressure and touch through Validated 3 point scale.
