Abstract:
Objective To observe the efficacy of bacterial lysate(bronchovaxom) in the acute phase of respiratory tract infection and to prevent recurrent respiratory tract infections.Methods From April 2014 to A-pril 2015,in pediatric respiratory ward of Shengjing hospital of China Medical University,80 children with recur-rent respiratory tract infection were randomly divided into treatment group and control group,with 40 cases in each group.The control group patients were received routine anti-infection and symptomatic treatment,the treat-ment group patients were received oral bacterial lysis products for 3 months on basis of the conventional anti-in-fection and symptomatic treatment.To observe the duration of clinical symptoms of two groups of children with respiratory tract infection in the acute phase,antibiotic use and hospital stay changes;observed the number of re-spiratory infections occurred again within 1 year;measured the levels of serum immunoglobulin before and 6 months after treatment. Results Compared with the control group,the duration of symptoms such as fever, cough and other symptoms of respiratory tract infection,the duration of pulmonary rales,the use of antibiotics and the length of hospital stay were significantly shortened in the treatment group,and the number of respiratory infections was significantly reduced,the difference significant(P<0.05).After treatment,the levels of IgG and IgA in the treatment group were significantly higher than those before treatment,and the immunoglobulin IgG and IgA in the treatment group were significantly higher than those in the control group(P<0.05).Conclusion Oral bacterial lysis products to prevent respiratory infections,not only can reduce the duration of various clini-cal symptoms of respiratory tract infection,shorten the use of antibiotics and hospital stay,and can improve chil-dren's immunity,reduce the number of respiratory infections again.
