Evaluation of Success Rate of Brachial Plexus Block by Selective Cord Stimulation
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2018, Vol 5, Issue 11
Abstract
Aims and Objectives: The aim is to study and compare the success rate of brachial plexus block achieved by stimulation of individual cord, that is, medial, lateral, and posterior cord. Introduction: Infraclavicular block is indicated for surgery of the forearm, wrist, and hand. It is performed by localizing one cord of the brachial plexus and injecting the local anesthetic solution at that location. In this study, we compare the success rate of brachial block achieved by stimulating individual cord, that is, posterior, medial and anterior. The approach used with the help of nerve stimulator at a stimulator current of 0.4 mA or less infraclavicular vertical brachial plexus block approach. Materials and Methods: A total of 108 patients who were planned to undergo forearm or hand surgeries were divided into three groups. Infraclavicular brachial plexus block (ICPB) was performed using 50-mm insulated nerve stimulator needle and B. Braun Stimuplex RC nerve stimulator with an initial stimulator current of 1.0 mA with 2 Hz frequency. The patients belonging to the respective groups would receive ICPB after attaining the evoked muscle response. Result: After prospective, randomized comparative study which was carried out in 108 patients, result achieved was that in comparison to the lateral and medial cord, posterior cord blockade was associated with rapid onset of motor block and sensory block with selective cord stimulation and this also decreased the incidence of block failure.
