Abstract
Objective: to evaluate the efficacy and safety of Thermal versus pulsed radiofrequency application of Stellate ganglion in sympathetic mediated pain in cancer patients Methodology: 60 patients randomly integrated into 2 equal groups: group (A): pulsed or group (B): thermal R.F therapy was done under fluoroscopy integrated by ultrasound guidance. Patients were assessed for pain relief (VAS score) at 1st day then 1 and 3 months after. Oxycodone and pregabalin consumption were assessed prior to block and at 3 months Results: Percentage of patients who had complete pain response was significantly higher in thermal group than pulsed group at first day, first month and three months. There is significant higher number of patients with higher percentage reduction of pregabalin and oxycontin consumption in the thermal group compared to the pulsed group. Conclusion: Thermal RF of the Stellate ganglion is a safe and successful treatment for cancer patients with sympathetic mediated pain. It appears to be more effective than pulsed RF of the Stellate ganglion.
