Does subcutaneous infusion of lidocaine provide effective pain relief for CRPS patients? Context: Nine patients with Complex Regional Pain Syndrome types I and/or II (CRPS), previously known as reflex sympathetic dystrophy (RSD) and causalgia, respectively, were selected for treatment with a continuous four to eight week subcutaneous infusion of 10% lidocaine.

Five patients completed the infusion treatment. The treatment significantly alleviated much of the pain and other symptomatology (i.e., dysesthesia, allodynia, hyperpathia, color and temperature changes, decreased range of motion of involved extremities, changes in hair and nail growth, etc.) commonly observed for CRPS/RSD patients. Upon discontinuation of the continuous subcutaneous infusion, patients appear to maintain the pain relief obtained. Periodic maintenance infusions may be needed. Final Decision: yes
