ABSTRACT
Objective To observe and analyze the clinical effect of noninvasive sputum aspiration combined with atomization inhalation in the treatment of pediatric bronchiolitis. Methods Totally 79 children with bronchiolitis diagnosed from January 2016 to December 2017 were selected. The children were divided into observation group (40 cases) and control group (39 cases) by double blind method of stratified random sampling. The observation group were treated with atomization inhalation after noninvasive sputum aspiration;and the control group were treated with the traditional inhalation of sputum according to the condition of the disease.The improvement effect of the symptoms before and after the treatment of the two groups was compared. Results After treatment, the improvement of symptoms in the two groups included cough, fever, wheezing, shortness of breath, lung rales, daily sputum aspiration and hospital stay were (5.34±1.06) d, (1.82±0.35) d, (2.66±0.85) d, (1.76±0.39) d, (4.37±1.29) d, (6.38± 1.39) times, (6.31 ± 0.82) d in the observation group, (6.25 ± 0.98) d, (2.34 ± 0.41) d, (3.08 ± 0.94) d, (2.56 ± 0.41) d, (5.39 ± 1.33) d, (8.31 ± 1.52) times, (8.25 ± 1.09) d in the control group, the difference was statistically significant( t=2.084-8.954, P<0.05). Respiratory function improvement including arterial oxygen saturation,heart rate,respiratory rate was 0.96±0.03, (110.85±4.16) times/min, (29.49±1.87) times/min in the observation group, 0.92±0.03, (119.34±4.22) times/min, (35.14±1.95) times/min in the control group,the difference was statistically significant(t=5.925, 9.005, 13.146, P<0.05). The effective rate of the observation group was 97.50％ (39/40), which was significantly higher than that of the control group 79.49％(31/39), the difference was statistically significant (χ2=4.688, P<0.05).The satisfaction rate of the family members of the observation group of the nebulization and sputum suction service was 100.00％(40/40), which was significantly higher than that of the control group (87.18％, 34/39), the difference was statistically significant (χ2=13.698, P<0.05). Conclusions Noninvasive sputum aspiration combined with atomization inhalation is effective in the treatment of pediatric bronchiolitis. It can relieve airway obstruction, improve asthma symptoms, shorten the time of hospitalization, and the operation is convenient and safe.
