[Pay attention to the clinical application of radiofrequency ablation in the treatment of neuropathic pain].

Neuropathic pain is the pain triggered or caused by primary damage and dysfunction of the nervous system. Its pathogenesis is complex, involving changes in ion channel function, abnormal action potential generation and expansion, and central and peripheral sensitization. Therefore, it has always been the most intractable problem in clinical pain diagnosis and treatment, and there are many kinds of treatment methods. In addition to various oral drugs, nerve block, pulsed radiofrequency, radiofrequency ablation, central nerve electrical stimulation, peripheral nerve electrical stimulation, intra-thecal infusion system, craniotomy nerve decompression or carding, the dorsal root entry zone disfigurement, etc. various methods have mixed efficacy. So far, radiofrequency ablation of peripheral nerves is still the most simple and effective means for the treatment of neuropathic pain. In this paper, the definition, clinical manifestations, pathological mechanism and the treatment methods of radiofrequency ablation of neuropathic pain were expounded, in order to provide reference for related clinicians in radiofrequency ablation.
