Assessement of a new approach of an ultrasound guided brachial plexus blockade between the infraclavicular and axillary area.
After an assessement of this new approach of ultrasounded-guided brachial plexus blockade in cadavers, the aim of this human study was to asssess the validity of this method in humans. The probe will be disposed on the shoulder, and the brachial plexus will be seeked below the deltoid, lateral to the major pectoralis muscle and in the vicinity of the brachial artery. At this area, an ultrasounded guided needle was inserted with an in-plane direction towards the brachial artery and local anesthetics was disposed all around the artery, without puncturing the differents nerves. Regional blockade will be evaluated by measuring onset and duation time for sensitive and motor blockade, effectiveness of this blockade, patient's confort during the procedure, ease of the procedure for practitionner, quality of ultrasound image's interpretation before and after injection.
