ObjectiveTo observe the clinical efficacy of triple aerosol inhalation of pulmicort respules,ipratropine and ventolin in treatment of severe acute asthma exacerbations in adults. Methods46 cases of severe asthmatic patients with acute exacerbations admitted between May 2011 and May 2013 were recruited in the study.They were randomly divided into a treatment group and a control group,23 cases in each group.The control group received aminophylline and methylprednisolone intravenously,while the treatment group received triple aerosol inhalation of pulmicort respules,ipratropine and ventolin on the basic treatment of the control group.The clinical efficacy,the score of asthma symptom of the day and night,the time of disappearance of symptoms and wheezing sound,the glucocorticoid dosage and the incidence of adverse reactions of each group were compared. ResultsComparison of clinical efficacy of two groups drew significant differences (P<0.05) after 7 days.The score of asthma symptom of the day and night in the treatment group was lower than that of the control group (P<0.05).Except cough,the duration of wheezing,breathlessness,chest distress and extinction time of wheezing sound in the treatment group were shorter than those in the control group (P<0.05).The triple inhalation therapy can reduce the dosage and shorten the period of intravenous glucocorticoid treatment with slight adverse reactions (P<0.05). ConclusionIn the treatment of severe asthmatic patients with acute exacerbations,the clinical efficacy of triple aerosol inhalation of pulmicort respules,ipratropine and ventolin on the base of intravenous treatment is satisfactory with rapid onset,which can also reduce the glucocorticoid dosage and the incidence of adverse reactions.So the combination therapy is worthy of clinical use.
