Clinical observations of elderly patients with severe chronic obstructive pulmonary disease and inhaled corticosteroids

Abstract

Objective To investigate the curative effects of old age severe chronic obstructive pulmonary disease (COPD) patients inhaled Glucocorticoids with the special devices (Turbuhaler).Methods Seventy-six cases of elderly patients with severe acute exacerbation of COPD patients (53 males,23 females) were divided into experimental group(n =38) and control group(n =38),respectively,according to the random number table.In 10 days of therapy,patients of experimental group inhaled budesonide powder of inhalation 0.2 mg twice daily;Control group inhaled oxygen atomization budesonide suspension 1mg twice daily.The changes of panting symptom were observed.Three months followed-up,the test team inhaled budesonide powder of inhalation 1 mg twice daily,control group stopped inhaling drugs,all patients of panting symptom were observed,also were six-minutes walking distance,the frequency of acute exacerbation and adverse reaction.Intent and compliance program data analysis were performed of the experimental data.Results At the end of the stage of therapy,panting symptom of two group patients were all improved (F =8.746,7.952 respectively,P ＜ 0.05) ; Wheezing score between the two groups 1,5,10 days of treatment differences were not statistically significant(P ＞ 0.05).But the incidence rate of adverse reaction in experimental group was significantly lower than that of control group(x2 =11.372,P ＜0.01),and the treatment costs of test team was significantly lower than that of control group(t =4.573,P ＜ 0.01).At the start of the follow-up period (week 0),two groups of acute exacerbation frequency,wheezing,peak expiratory flow and 6 minutes walking distance had no significant difference(P ＞ 0.05).When follow-up period was at tne end of 12 weeks.The test group of patients with acute exacerbation frequency was significantly lower than the control group(aF within grouP =9.343,aF between groups =16.343,the aF interaction =20.017 ; P ＜ 0.05),wheezing in the control group was significantly mitigate (bF within group =8.537,b F between groups =11.453,bF interaction =13.071 ; P ＜ 0.05),and peak expiratory flow rate than the control group improved significantly (cF within group =9.015,cF between groups =12.426,cF interaction =14.852 ;P ＜ 0.05),6 min walking distance increased significantly compared with the control group (d F within group =12.263,d F between groups =21.371,d F interactive =24.651 ; P ＜ 0.05),the differences were statistically significant.Conclusion Elderly patients with moderate to severe COPD inhaled Glucocorticoids,with the special devices(Turbuhaler),not only in acute exacerbation stage the panting symptom was controlled; but also in stable phase the frequency of acute exacerbation was decreased,and the exercise tolerance was improved.Curative effect is obvious withsafety and well-tolerated.
