Abstract:
Objective：To explore the effect of adjunctive therapy of Zhichuanling oral liquid combined with magnesium sulfate in the treatment of children with asthmatic bronchial pneumonia.
Methods：A total of 110 cases of asthmatic bronchial pneumonia were randomly divided into control group(n=55) and treatment group(n=55). The control group was given conventional clinical therapy, while the treatment group was given adjunctive therapy of Zhichuanling oral liquid combined with magnesium sulfate. Then, the extinction time of symptoms and physical signs, length of hospital stay, total effective rate and adverse effect were compared between the two groups.
Results：Extinction time of coughing, gasping and wheezing rale and length of hospital stay in the treatment group were much shorter than the control group(P＜0.01) after treatment. The total effective rate of the treatment group was 92.7%, much higher than the control group(76.4%, P＜0.05). The adverse effect rate in the treatment group was 16.4%, the difference being no statistical significance compared with the control group(18.2%，P＞0.05).
Conclusion：For children with asthmatic bronchial pneumonia，adjunctive therapy with Zhichuanling oral liquid combined with magnesium sulfate could obviously improve clinical symptoms and physical signs, increase curative effect and reduce adverse effect, which deserves to be used in clinics.
