The Clinic Effects of Thoracic Dorsal Root Ganglion Pulsed Radiofrequency in Treating Post - thoracotomy Pain Syndrome / 现代医院

ABSTRACT

Objective To observe the clinic effects and safety of thoracic dorsal root ganglion(DRG) pulsed radiofrequency in treating post-thoracotomy pain syndrome(PTPS). Methods 47 PTPS patients were treated with thoracic DRG pulsed radiofrequency. VAS, Oxycodone dosage, medicine side effects before and after operation were recorded. Results The VAS before operation and 1 d, 15 d, 1 m, 3 m, 6 m, 12 m after operation were 6. 3 ±2. 4, 4. 1 ±1. 8, 3. 2 ±1. 3, 2. 5 ±1. 5, 2. 1 ±0. 9, 2. 0 ±0. 8 and 2. 2 ±1. 1 respectively. The oxycodone dosage were (28. 5 ±10. 2)mg, (12. 3 ±5. 7)mg, (8. 3 ±3. 8)mg, (7. 6 ± 3. 1) mg, (7. 0 ± 3. 4) mg, (6. 6 ± 2. 7) mg and (7. 2 ± 3. 2) mg respectively. The difference was significant compared with the preoperative (P＜0. 05). No serious complications occurred. Conclusion Thoracic DRG pulsed radiofrequency was a safe and effective method in treating PTPS.
