Official Title: Diagnosis of Diaphragmatic Paralysis After Interscalene Block by Measuring the Inspiratory Diaphragmatic Thickening: Feasibility and Impact Observed

Brief Summary:

  1. INTRODUCTION AND MAIN OBJECTIVES The incidence of diaphragmatic paralysis after an inter-block scalénique varies between 30 and 100% in the literature. Its clinical impact is mostly absent and paralysis regresses after the block lifted. When it is suspected, it can be diagnosed by a chest radio, showing an elevation of the dome.

    The objective of this study is to evaluate the incidence of diaphragmatic paralysis by measuring the thickness diaphragmatic as quantitative assessment of diaphragmatic contraction noninvasive ultrasound scan and feasibility of this measure in SSPI unit (post-interventional monitoring unit) with scan (ultrasound) in the usual way used for the block under ultrasound scan.

  2. STUDY TYPE Prospective, single-center clinical study routine care involving 50 consecutive patients scheduled to undergo surgical procedures in the area of the shoulder or arm for which locoregional analgesia inter-block type scalénique or supraclavicular ultrasound scan is indicated below.
  3. START OF THE STUDY February 2014 with an expected duration of six months.
