脉冲射频治疗三叉神经痛时射频电压与疗效的关系

摘要

目的 探讨脉冲射频治疗三叉神经痛时射频电压与术后镇痛效果的关系.方法 选取脉冲射频治疗后效果欠佳的原发三叉神经痛患者22例(无效组)及同期随机选取脉冲射频效果满意的患者22例(有效组),比较两组患者术中射频电压、局部电阻、刺激电压等数据,并且比较两组术后并发症发生情况.结果 有效组射频电压明显高于无效组(P＜0.01),面部麻木患者明显多于无效组(P＜0.01).结论 脉冲射频电压高的患者治疗效果更好.%Objective To investigate the relationship between pulsed radiofrequency voltage and therapeutic effect on idiopathic trigemi-nal neuralgia. Methods 22 idiopathic trigeminal neuralgia patients treated with standard pulsed radiofrequency ineffectively and other 22 patients with satisfactory effect were included. The pulsed radiofrequency voltage, electric resistance, stimulating voltage and postoperative complications were compared. Results Pulsed radiofrequency voltage in the effective group was more than that in ineffective group (P< 0.01). More patients suffered from mild numbness in the pulsed radiofrequency effective group (P<0.01). Conclusion The pulsed radiofrequency voltage is an important factor affecting the therapeutic effect.
