Comparison of analgesic efficacy of caudal Dexmedetomidine versus caudal Tramadol with Ropivacaine in paediatric infraumblical surgeries: A Prospective randomised study

This will be a prospective randomised study conducted to evaluate injection dexmedetomidine 2mcg/kg and inj. tramadol 2mg/kg as an adjuvant with injection ropivacaine 0.75% caudally in paediatric patient who are between 1 to 8yr old 

ASA grade 1 or 2 with exemption of all exclusion criteria mention above and undergoing infraumblical surgeries under caudal analgesia with primary objective of  comparing the duration of analgesia secondary objective being onset and duration  of sensory block and cardiovascular effect, side effect. Participant will be allocated in two group each with 17 sample size.
