Study On The Incidence Of Complex Regional Pain Syndrome After The Upper Extremity Surgery With Brachial Plexus Anesthesia And Stellate Ganglion Block

Objective： Observed the incidence rates of complex regional pain after acomprehensive summary (CRPS) in the upper extremity surgery using brachial plexusblock and stellate ganglion block (SGB).Method：140cases (ASA classⅠ－Ⅱ) of upper brachial plexus surgery wererandomly divided into two groups (A group70cases, B group70cases). In anesthesiaprocedures, the cases in A group were treated with brachial plexus block and stellateganglion block (SGB), B group with non-stellate ganglion block. In A group, Hornersyndrome occured and obtained good anesthetic effect of sensorimotor in the surgicalarea before surgery. The local anesthetics were both:0.33%ropivacaine+1.33%lidocaine30ml in A and B group. We followed up these cases for3-month andcompared the incidence of complex regional pain syndrome (CRPS) between A and Bgroup. The diagnostic criteria of CRPS followed International Association for theStudy of Pain (IASP,2007).Result：The incidence of CRPS in A group was significantly lower than in Bgroup(P <0.05).Conclusion：treatment with brachial plexus block and stellate ganglion block(SGB) is helpful to reduce the incidence of CRPS, and helpful to improve the cases’limb physical function and quality of life.
