Clinical Studies Of Vitamin A Adjuvant Treatment Of Recurrent Respiratory Tract Infections

Purpose:To research the clinical effect of VitA adjunctive therapy for recurrent respiratory tract infection.Material and method:Divide the selected 80 cases into the treatment group and the control group according to the stochastic grouping principle. Each group contains 40 people. The selected 80 cases are given upper respiratory tract infection convention therapy, including drinking more water, anti-infection, defervescence, relieving cough and reducing sputum. The treatment group extra uses one tablet of VitA (25000units) once daily for thirty days. Criterion of therapeutical effect: produce effects is that the rate of incidence of RRTI decreased and the course of disease cut down. Effective result is that the rate of incidence of RRTI doesn't decrease but the course of disease cut down and clinical symptoms alleviated. Resultless is that the three norms aren't improved.Results:1. After one month-long treatment, the two groups of patients'conditions have the obvious change for the better. The overall curative effect: the treatment group (95.0%) is obviously better than the control group (67.5%).2. The clinical effect of VitA adjunctive therapy for recurrent respiratory tract infection is better.Conclusion:1. This research confirmed that both the VitA adjunctive therapy and the pure application routine treatment have the obvious treatment result to RRTI. But VitA adjunctive therapy for recurrent respiratory tract infection has a more remarkable clinical effect.2. The clinical effect of VitA adjunctive therapy for recurrent respiratory tract infection is well. It can decrease the rate of incidence of RRTI and cut down the course of disease.
