Summary

The first purpose of this study is to compare the effectiveness of the stellate ganglion block realized with two different approaches (blind and ultrasound-guided) in patients with a diagnosis of complex regional pain syndrome. The second purpose of this study is to determine the safest approach and to compare the safety profiles of the two approaches.

Detailed description

To evaluate whether the ultrasound guided approach is more effective than the blind technique in producing a greater than 1.5 degree Celsius rise in ipsilateral arm temperature after a stellate ganglion block. Blocks will both be performed with 10 mL of xylocaine/bupivacaine. Secondary outcomes will be the impact of the approach (blind vs ultrasound) on pain reduction, horner syndrome, side effects (hoarseness, dysphagia, pharyngeal discomfort) and complications (blood aspiration, intravascular injection).

Conditions

• Complex Regional Pain Syndromes
