COMPARISION OF DEXMEDETOMIDINE VS DEXAMETHASONE AS AN ADJUVANT FOR 0.5%ROPIVACAINE IN ULTRASOUND GUIDED SUPRACLAVICULAR BRACHIAL PLEXUS BLOCK IN UPPER LIMB ORTHOPAEDICS SURGERIES

A hospital based comparative study of  dexmedetomidine vs dexamethasone as an adjuvants for 0.5% ropivacaine in ultrasound guided supraclavicular brachial plexus block.

INTRODUCTION:Ultrasound guided Supraclavicular brachial plexus block (SCPB) is  used for upper limb orthopaedics surgeries with ease, reliability, and a few complication rates. Both addition of dexamethasone and dexmedetomidine have been found to prolong the duration of anaesthesia. However, there has been few studies conducted to compare the effects of dexamethasone and dexmedetomidine added as adjuvants to the ropivacaine for supraclavicular brachial plexus block. This study will be conducted with the primary aim of evaluating the effect of dexmedetomidine to that of dexamethasone as a better medication for a prolonged anesthesia and with minimum complications

ASA grade I & II  patients aged 18-60 years posted for   orthopaedic upper limb  surgeries at Sri Siddhartha Medical College and Research Centre, Tumkur will be selected for the study.Period of 24 months with sample size of 60 patients.

All patients as per inclusion and exclusion criteria posted for elective orthopaedics surgical procedures will be taken in the study
