Randomized Controlled Trial Clinical Trial[Brachial plexus block. Effect of low interscalenic approach on phrenic nerve paresis].
The aim of the paper was to determine the influence of the brachial plexus block on phrenic nerves paralysis in distal side of interscalenic space (between 1/3 medium and 1/3 inferior), with little volume of local anesthetic drug. Comparative, prospective, randomized study. ⋯ Brachial plexus anesthesia by low interscalenic tract, even using little local anesthetic drug volumes, like other supraclavear block techniques determines ipsilateral diaphragm paralysis.
