This is a prospective and observational study designed to determine if the changes observed in finger photoplethysmographic waveform of surgical patients is related to a local or a sistemic changes in the vascular tone. The investigators will studied 15 patients undergoing regional brachial plexus anesthesia for upper limb surgeries. Photoplethysmography will be continuously recorded in the thumb of the tested hand (anesthetized hand) and in the thumb of the control, opposite hand. Duplex color and power Doppler will measure flow in the both brachial arteries and in the aorta (supraesternal view). The contour analysis of both, photoplethysmogram and arterial flow velocities will be analyzed, correlated and compared.
