Estudo Comparativo entre Ultrassom e Neuroestimulação no Bloqueio do Plexo Braquial pela Via Axilar * A Comparative Study between Ultrasound and Neurostimulation Guided Axillary Brachial Plexus Block*

SUMMARY Conceicao DB, Helayel PE, Oliveira Filho GR – A Comparative Studybetween Ultrasound- and Neurostimulation-Guided Axillary BrachialPlexus Block. BACKGROUND AND OBJECTIVES: The use of ultrasound in Re-gional Blocks is increasingly more frequent. However, very fewstudies comparing ultrasound and neurostimulation have beenconducted. The objective of this study was to compare neurostimu-lation-guided axillary brachial plexus block with double injectionand ultrasound-guided axillary plexus block for hand surgeries. Thetime to perform the technique, success rate, and complications werecompared. METHODS: After approval by the Ethics on Research Committeeof the Hospital Governador Celso Ramos, 40 patients scheduled forelective hand surgeries under axillary plexus block were selected.Patients were randomly divided into two groups with 20 patientseach: Neurostimulation (NE) and Ultrasound (US) groups. The timeto perform the technique, success rate, and complication rate werecompared. RESULTS:
