目的:觀察雷射針灸治療末期腎病血液透析患者尿毒搔癢症之療效。方法:使用真、偽雷射針灸儀器三盲隨機試驗。雷射針灸組以雷射針灸儀器刺激患者雙側曲池(LI11)、神門(HT7)穴位。每穴位刺激時間40秒,每週3次連續4週。偽雷射針灸組的治療與取穴模式與雷射針灸組相同。其中治療組20例和安慰組18例,在治療前、後及治療後4週應用視覺類比量表(Visual Analogue Scale; VAS)及搔癢量表(Pruritus Score)進行問卷評估。結果:雷射針灸組與偽雷射針灸組,患者的VAS及搔癢量表於實驗結束後及實驗結束後4週無明顯差異。全數受測者無任何不良反應。結論:使用雷射針灸治療血液透析患者尿毒搔癢症,以曲池、神門穴為處方的療效與偽雷射針灸組相比無明顯差異。
Purpose: To investigate the effect of laser acupuncture on hemodialysis patients with refractory uremic pruritus. Method: In a triple blinded randomized controlled trial, 20 patients treated with laser acupuncture, 18 patients received sham laser acupuncture. Each patient received 40 seconds treatment for each acupuncture point on bilateral LI11 and HT7 three sessions per week for four weeks. The visual analogue scale (VAS) and pruritus score were evaluated before, after and 4 weeks after treatments. Result: Both laser acupuncture and sham laser acupuncture group showed no difference on VAS and pruritus score before, after and 4 weeks after treatments. No subject had any adverse reaction. Conclusion: The effect of laser acupuncture treatment using LI11 and HT7 was not significantly different compared to sham laser acupuncture on refractory uremic pruritus in hemodialysis patients.
