Study of Two Different Volumes of 0.75% Ropivacaine for Ultrasound Guided Supraclavicular Brachial Plexus Block on Successful Blockade and Diaphragmatic Motility

Background 
 Use of ultrasound guidance during supraclavicular brachial plexus block allows the usage a lower anesthetics dose and minimizing unwanted effects anesthesia.
 Objective To compare success sensory blockade incidence hemidiaphragmatic dysfunction in patients receiving two different volume 0.75% Ropivacaine for guided block.
 Method A prospective randomized double-blinded comparative study was conducted. Group (n=30) received 20 ml B 25 block. Hemodynamic parameters, oxygen saturation, diaphragmatic excursion, onset time completion were measured. Independent t-test, Chi-square test Mann-Whitney U used to analyze data at p value less than 0.05 using Statistical Package Social sciences (version 11.5).
 Result At 30 minutes, 29 (96.67%) group 27 (90.0%) had no sensation median, radial, ulnar, musculocutaneous medial cutaneous nerves territories; however, it not significant statistically (p > 0.05). minutes A, (83.33%) hemiparesis five (16.67%) partial hemiparesis. However, three (10%) B, (6.67%) complete < Age sex effect on both groups 0.05).
 Conclusion The with similar as compared higher Ropivacaine.
