title: Intravenous regional block with lidocaine for treatment of complex regional pain syndrome.
abstract: OBJECTIVE
  The goal of this article is to report the successful treatment of a patient with complex regional pain syndrome (CRPS) type 1 involving the hand with the use of an intravenous regional block.
  
  
  METHODS
  The patient was a 35-year-old woman who developed CRPS during conservative therapy for a metacarpal fracture. An intravenous regional block with lidocaine alone, using a two-tourniquet technique, was delivered 10 times for at least 40 minutes. The first five treatments were given twice a week and the next five were delivered weekly. All affected joints, including the wrist, were manipulated without undue force. Functional physical measurements were assessed, including range of motion and performance of fine and gross motor tasks.
  
  
  RESULTS
  The visual analog scale scores for pain declined from 10 to 0 after treatment. Use of a pen, a pair of chopsticks, and a hammer improved, and edema decreased.
  
  
  CONCLUSIONS
  Intravenous regional block with lidocaine was well tolerated and associated with relief in this case of CRPS type 1.
