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.

Conditions

  • Shoulder Fractures
  • Arm Fractures

Interventions

OTHER

Ultrasound scan

Non-invasive and non-irradiating. The diaphragmatic thickening in recovery is measured before and after the completion of the anesthetic block using the ultrasound system, the ultrasound probe and of an aqueous gel by trans-thoracic approach. It measures the thickness on deep inspiration and expiration in supine position. Each measurement is repeated twice. This measurement series lasts 4 minutes, is repeated 15 minutes after completion of the engine block when a block is found and contralateral. The total measurement time is about 12 minutes.
