Analysis of Peak Magnitude and Duration of Analgesia Produced by Local Anesthetics Injected into Sympathetic Ganglia of Complex Regional Pain Syndrome Patients

Abstract

The combination of these results provides evidence that duration of pain relief is affected by injection of local anesthetics into sympathetic ganglia. These results indicate that both magnitude and duration of pain reduction should be closely monitored to provide optimal efficacy in procedures that use local anesthetics to treat CRPS.
