Effect of Qinghua Kechuan Decoction on Treatment of Acute Exacerbation of Chronic Bronchitis in Elderly Patients with Syndrome of Phlegm-heat Stagnated in Lungs and Its Impact on Blood Gas Indexes
Objective:To observe the effect of Qinghua Kechuan Decoction in the treatment of elderly patients with acute exacerbation of chronic bronchitis(syndrome of phlegm-heat stagnated in lungs)and its impact on blood gas indexes.Methods:90 elderly patients admitted were selected.Patients were randomly assigned to a con-trol group(n=45)receiving conventional western medical treatment and a study group(n=45)receiving conven-tional nursing care.The treatment outcomes of both groups were compared.Results:The effective rate of treat-ment in the study group was 95.56％,which was significantly higher than 82.22％in the control group(P＜0.05).After treatment,the scores for cough,sputum volume,sputum characteristics,and chest fullness in the study group were significantly lower than those in the control group(P＜0.05).After treatment,the serum inflammatory factor levels(SAA,CRP,PCT)were significantly lower in the study group compared with the control group(P＜0.05).Af-ter treatment,the blood gas indexes(PaCO2,PaO2,pH)were higher in the study group compared with the control group,while SaO2 levels were lower in the study group compared with the control group(P＜0.05).Conclusion:Qinghua Kechuan Decoction shows significant clinical effects in the treatment of acute exacerbation of chronic bronchitis in elderly patients with syndrome of phlegm-heat stagnated in lungs.After treatment,inflammatory fac-tor levels are significantly reduced,and blood gas indexes are significantly improved.
