A total of 55 patients (26 males and 29 females) were included in our study. These patients were hospitalized because of positive RT-PCR results. The patients were randomly divided into two groups, 32 cases in the control group and 23 cases in the experimental group. The minimum and maximum ages were 35 and 100 years old, respectively. Patients were treated according to the procedure shown in Flow chart of the clinical trial.Several important factors such as gender, age, and health status were studied. The mean ± SD of these factors are shown in Statistical analysis of difference between the two groups.Scatter plots of hospitalization time.We proposed three possible reasons for this: (1) the main infection area of coronavirus is the upper respiratory tract. Most coronaviruses were washed away during nasal irrigation and oral rinse (Nasal irrigation and oral rinse is very simple, which can be operated by the patient. In addition, sodium bicarbonate is a cheap and widely used alkaline reagent. COVID-19 patients can rinse nose and mouth with sodium bicarbonate solution to clear coronaviruses even at home, which is significant for areas lack of medical resources. We believe this method is not only effective for COVID-19, it might be useful for some other diseases such as influenza.
