Abstract：Objective To explore the clinical effect of Salmeterol Fluticasone + low-dose Erythromycin in the treatment of bronchiectasis.Methods A total of 120 patients with bronchiectasis admitted to our hospital from June 21, 2018 to June 21, 2019 were selected as the research objects, and they were randomly divided into two groups according to the single and double numbers, 60 cases in each group, and the control group was treated with Erythromycin, the observation group was treated with Salmeterol Fluticasone + low-dose Erythromycin, and then the forced vital capacity (FVC),peak expiratory flow rate (PEF), forced expiratory volume in one second (FEV1), cough sputum score, cough score,shortness of breath score, total incidence of adverse reactions, time of disappearance of sputum, time of disappearance of lung rales, and time of body temperature returning to normal were compared.Results The PEF ([4.76±0.37] L/s), FVC([2.76±0.41] L), FEV1([1.92±0.46] L) of the observation group after treatment were higher than those of the control group PEF ([3.49±0.42] L/s), FVC ([2.11±0.19] L), FEV1 ([1.45±0.11] L), the differences were statistically significant (P＜0.05).The observation group′s shortness of breath score ([0.37±0.08] points), expectoration score ([0.44±0.19] points), cough score ([0.62±0.19] points), the total incidence of adverse reactions (3.33%) were lower than those of the control group for shortness of breath score ([1.54±0.27] points), expectoration score ([1.65±0.28] points), cough score ([1.43±0.28]points), total incidence of adverse reactions (26.67%), the differences were statistically significant (P＜0.05), the time of disappearance of lung rales in the observation group ([3.16±0.52] d), the time of disappearance of sputum ([1.26±0.68]d), the time of body temperature returning to normal ([2.27±1.54] d) were all shorter than those of the control which the disappearance time of lung rales [(4.87±1.55) d], the disappearance time of sputum ([3.68±1.53] d) and the time of body temperature returning to normal ([4.61±1.27] d), the differences were statistically significant (P＜0.05).Conclusion Salmeterol Fluticasone plus low-dose Erythromycin in patients with bronchiectasis has a significant effect, which can reduce the incidence of adverse reactions.
