Purpose
This is a double-blind randomized controlled trial to evaluate the efficacy of the sympathetic block via thoracic vertebra T3 for the treatment of CRPS I upper limb. Patients with CRPS I refractory to medical treatment will be subjected to four physical therapy sessions and then the randomized for experimental or control block and then more four physiotherapy sessions. Patients will be evaluated after one month of the blockade (primary outcome) and then up to 12 months. Will be evaluated by analgesic scale (Mcgill, brief pain inventory, dn4 questionnaire, NPSI, VAS), functional (ADM) and quality of life (HAD and WHOQOL-brief).

Experimental: thoracic sympathetic block
Sympathetic block of upper limb via thoracic vertebra T3
|
Procedure: thoracic sympathetic block
Thoracic sympathetic block is sympathetic block of upper limb described by Leriche e Fontaine em 1925. The block is performed under radioscopic view, positioning the needle lateral the body of thoracic vertebra T3, where infuse anesthetic solution. The theoretical advantage over the stellate ganglion is its greater specificity and efficiency. Solution block: 5ml ropivacaine 0,75% + 5ml de triamcinolone 2%

Active Comparator: control block
Same medication used in experimental group, but in dorsal subcutaneous
