Background/aim: Pulsed radiofrequency (PRF) has been reported to be a safe and reliable method for the management of a variety of chronic pain syndromes. It is not known whether the preadministration of local anesthetic increases the size of the electrical field. We revealed the effects of administering local anesthetic on PRF and investigated whether they were related to local anesthetic or fluid effects. Materials and methods: Group 1 (n = 18) received PRF to the suprascapular nerve with 1 mL of bupivacaine, group 2 (n = 20) received PRF with 1 mL of physiological saline solution, and group 3 (n = 18) received PRF only. Results: There were significant improvements in visual analog scale (VAS) scores at 30 min, 1 month, and 3 months after treatment in group 1 (P < 0.05) and at 1 month and 3 months in groups 2 and 3 (P < 0.05). There was a significant improvement in VAS scores in group 1 compared with groups 2 and 3 at 30 min after treatment. Conclusion: PRF applied to the nerve along with local anesthetic may increase pain relief, especially in the early posttreatment period. The favorable effects may depend on the pharmacodynamic features of the local anesthetic .
背景/目的：据报道，脉冲射频（PRF）是一种用于治疗多种慢性疼痛综合征的安全可靠方法。局部麻醉药预给药是否会增加电场大小尚不清楚。我们揭示了局部麻醉药给药对PRF的影响，并研究了这些影响是否与局部麻醉药或液体效应有关。材料和方法：第1组（n = 18）接受向肩胛上神经注射1 mL布比卡因的PRF治疗，第2组（n = 20）接受注射1 mL生理盐水的PRF治疗，第3组（n = 18）仅接受PRF治疗。结果：第1组在治疗后30分钟、1个月和3个月时视觉模拟评分（VAS）有显著改善（P < 0.05），第2组和第3组在1个月和3个月时VAS有显著改善（P < 0.05）。治疗后30分钟时，第1组的VAS评分与第2组和第3组相比有显著改善。结论：与局部麻醉药一起应用于神经的PRF可能会增强疼痛缓解效果，尤其是在治疗后的早期。这些有利影响可能取决于局部麻醉药的药效学特性。
