Summary

The purpose of this study is to compare the efficiency and safety of 2ml versus 5ml of local anesthetics used in stellate ganglion blocks for the treatment of complex regional pain syndrome of the arm.

Detailed description

To evaluate if 2ml of 0.2% ropivacaine is less effective in decreasing pain scores by more than 50% when compared to 5ml of 0.2% ropivacaine. To evaluate if 2ml of 0.2% ropivacaine is causes less side effects when compared to 5ml after a stellate ganglion block.

Conditions

• Complex Regional Pain Syndromes

Interventions

Type	Name	Description
PROCEDURE	stellate ganglion block with ropivacaine 0.2% 5 mL	Each patient will undergo two stellate ganglion blocks and receive both volumes of local anesthetics in random order. The stellate ganglion blocks will be separated by 3 weeks in order to assure that no residual effects from the previous block will influence the results.
PROCEDURE	stellate ganglion block wit ropivacaine 0.2% 2 mL	Each patient will undergo two stellate ganglion blocks and receive both volumes of local anesthetics in random order. The stellate ganglion blocks will be separated by 3 weeks in order to assure that no residual effects from the previous block will influence the results.
