Effect of Two Different Volumes of Ropivacaine and Lignocaine at Two Different Sites in Ultrasound-Guided Supraclavicular Brachial Plexus Block on Diaphragm Motility

Ultrasound (USG) guided supraclavicular brachial plexus block (BPB) helps in precise delivery of local anesthetic injection, reduced volume or dose drug providing excellent surgical anesthesia with fewer complications. Objective the study was to compare effect two different volumes Ropivacaine and Lignocaine at sites USG-guided BPB on diaphragmatic motility, quality tourniquet pain. A prospective randomized double-blinded comparative conducted among adult patient below elbow elective surgery. In group patients (n=17), 20ml solution injected corner pocket 10ml nerve cluster USG. B 15ml 5ml Hemodynamic parameters, excursion, onset effects were measured frequent intervals. The data analyzed using Statistical Package for Social Sciences P-value less than 0.05. profile similar both groups (P-value>0.05). Statistically significant hemi-diaphragmatic dysfunction (partial complete paralysis) after 15 30minutes blockade more common Group (P<0.05). At 30 minutes injection anesthesia, all had sensory motor territory. Tourniquet time lower (80.35±9.59 vs 84.12±7.75 minutes); however, it statistically not present showed that who received lesser half required anesthetics incidence hemidiaphragmatic successful rate blockage (100%) as compared greater anesthetics.
