简要总结
Patients with indication of shoulder surgery will be submitted to ultrasound-guided interscalene brachial plexus block with 4ml or 15ml of bupivacaine- epinephrine 0,5%- 1:200,000 at level of C5-6 roots and will be evaluated their ventilation and pulmonary aeration by electrical impedance tomography
