RESUMEN
OBJECTIVE: To explore the short-term and long-term efficacy of buccal acupuncture therapy in the treatment of patients with primary dysmenorrhea (PD). METHODS: A total of 90 patients with PD who were admitted to the Second Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine from January 2020 to December 2021 were included in this study and randomly divided into three groups, including the observation group, the control group, and the placebo group, with 30 patients in each group. Patients in the observation group were treated according to the syndrome types of Traditional Chinese Medicine, those in the control group were treated with Saridon, and those in the placebo group received a placebo. The visual analog scale (VAS) scores of these patients were evaluated at different time points (before treatment, 5 min after needle retention, 30 min after needle retention, 1 h after treatment, 2 h after treatment, 1 d after treatment, and 2 d after treatment). The Cox Menstrual Symptom Scale (CMSS) scores were assessed before the treatment and after three courses of treatment. Besides, these two scales were also evaluated during follow-up. Moreover, the pain score and adverse reactions of these patients were assessed during treatment. RESULTS: After treatment, the VAS and CMSS scores in the observation group decreased significantly (P < 0.05) 5 and 30 min after needle retention and after treatment. CONCLUSION: Buccal acupuncture therapy is verified to have short-term efficacy in the treatment of PD. In addition, this therapy has an immediate analgesic effect and long-term efficacy in reducing the severity and frequency of PD.
