Brachial Plexus Block, Pulmonary Ventilation
Conditions
Brief summary
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

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Variation of pulmonary function | 4 hour | Evaluation of variation of pulmonary aeration and ventilation after interscalene brachial plexus block with 4ml or 15 ml of bupivacaine- epinephrine 0,5%1:200,0000. The pulmonary function will be evaluated by electrical impedance tomography. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Opioid consumption | 24 hours | Opioid consumption (Tramal - mg) will be recorded during the first 24 hours. |
| Post-Operative pain | 24 hours | The post operative pain will be evaluated using Visual Analog Score for pain during the first 24 hours. |
