Supraclavicular brachial plexus block is being routinely performed under ultrasound guidance for below elbow surgeries .It has many advantages as it allows the operator to visualize the needle and surrounding structures, minimizes the risk of contact with the pleural dome, and subclavian artery, decrease procedural times and increases block success .This study is a prospective ,randomized, double blind, single-centre trail to determine efficacy of supraclavicular brachial plexus block using blunt versus short bevel needle. A written informed consent from 60 patients American society of anesthesiologist (ASA) I�II, between 18 -60 years, of either sex, undergoing below elbow surgery will taken up for the clinical trial. The primary outcome measures will be efficacy of individual nerve blocks using blunt versus short bevel needle for supraclavicular block. The block effect will be assessed by an independent observer every 5 minutes in individual nerve territories both motor and sensory till the attainment of block or to a maximum of 60 minutes. Secondary outcome will be block performance time, procedure related pain, ideal block evaluation time, nerve block supplementation and early neurological sequel.
