Clinical effect of millimeter wave applied to acupoints on treatment of COVID-19

ABSTRACT

OBJECTIVE: To retrospectively observe the clinical effect of integrated Chinese and Western medicine combined with millimeter wave therapy on treatment of non-critical COVID-19 patients. METHODS: A total of 47 patients with COVID-19 who were treated in the People's Hospital of Hong'an County from Feb 2, 2020 to Feb 19, 2020 were enrolled in the study, the patients were given integrated Chinese and Western medicine therapies such as oxygen therapy, antiviral treatment, supportive treatment and Chinese patent medicine, and the millimeter wave therapy was applied to the acupoints twice a day. The respiratory function indexes such as oxygenation index and oxyhemoglobin saturation, chest CT, number of times of cough in a day and blood test indexes were collected after the millimeter wave treatment system was used for 1 day (T1), 3 days (T2), 10 days (T3) and 14 days (T4). RESULTS: The oxygenation index and blood oxygen saturation of the 47 patients were significantly higher at T2, T3 and T4 than at T1 after the integrated Chinese and Western medicine combined with millimeter wave therapy (P<0.05). There was significant difference in the percentage of the patients with grade 3 chest CT among all the time points except for T2 and T1 (P<0.05). There were significant differences in the number of times of cough and body temperature between the time points and T1 (P<0.05). The lactic dehydrogenase(LDH) level was slowly reduced, and there was significant difference between T4 and T1 (P<0.05). There were no significant differences in the white blood cell, lymphocyte, hemoglobin, potassium, sodium and chlorine at the admission. 4 patients were tested positive at T4, and the negative conversion ratio was 91.5%. CONCLUSION: The integrated Chinese and Western medicine combined with millimeter wave therapy can achieve remarkable effect on improvement of clinical symptoms of the COVID-19 patients such as oxygenation index and promote the nucleic acid to turn negative, and it has certain clinical application value.
