Effect of Auricular Acupressure on Uremic Pruritus in Patients Receiving Hemodialysis Treatment: A Randomized Controlled Trial.
Background. Uremic pruritus (UP) is a common symptom in patients undergoing maintenance hemodialysis for end-stage renal disease (ESRD). Objective. To determine the clinical efficacy of auricular acupressure therapy on pruritus in hemodialysis patients and to explore possible underlying mechanisms. Methods. Patients receiving maintenance hemodialysis at a referral medical center were recruited and assigned to intervention (n = 32) and control (n = 30) groups. The intervention group underwent auricular acupressure treatment three times a week for six weeks. Auricular acupressure was not applied to patients in the control group. However, tape without Vaccaria seeds was applied to the same six auricular acupoints as the intervention group. Pruritus scores were assessed using VAS scores, and enzyme-linked immunosorbent assays (ELISA) were used to measure levels of other possible contributory biochemical factors. Results. There was a significant difference in mean VAS scores between the postintervention and control groups during follow-up (3.844 ± 1.687 versus 5.567 ± 2.285, F = 22.32, P < 0.0001). Compared to the control group, serum histamine levels in the postintervention group at the six-week follow-up had decreased significantly (F = 5.01, P = 0.0290). Conclusion. Our findings suggest that auricular acupressure may be a useful treatment in the multidisciplinary management of UP in ESRD patients.
