Clinical Analysis For Common Incentives Of Acute Asthma Attack

ObjectiveTo investigate the incentives of asthmatic exacerbation and provide a theoretical basis forthe prevention and treatment of asthma.Methods1.250cases of asthma acute attack patients from the department of the First HospitalAttached to Shanxi Medical University are the research object.Cases were divided into threegroups according to age. The factors to trigger asthma attacks were analyzed2.Allergens were tested of70patients by sensitive screening method. Allergens were testedincluding households dust mites, house dust, dog and cat fur, eggs, milk, crabs, shrimp, beef andmutton, cashew, mould, Short ragweed, study, oak, elm grass, phoenix and so on..Result1.Respiratory tract infection was one of the most common causes led to asthmaticexacerbation，accounting for46.4%. Followed by inhaled allergen, accounting for26.4%. Foodallergens account for2.8%. Cold air stimulation accounts for4.4%. Mood changes accounts for1.6%. Drug accounts for0.8%. Movement accounts for0.4%. The other17.2%.2.Respiratory tract infection was also the most common causes led to asthmaticexacerbation in different age groups.Accounting for38.2%in the young group,45.1%in themiddle group and77.8%in the elderly group. Elderly group VS young group and middle groupwere significant different in statistics（P＜0.01）. As the inducing factors, inhaled allergensaccount for30.9%in the young group,27.5%in the middle group and8.3%in the elderly group.Young group VS ederly group were significant different in statistics（P＜0.01）.Middle groupVS ederly group were significant different in statistics（P＜0.05）.Other factors that led toasthmatic exacerbation had no statistically significant in different groups.3.In the70cases of patients with asthma exacerbation,40cases allergiced to a kind of ormore allergens, Overall positive was57.1%. Mildew detection rate was highest, accounting for27.1%. Followed by artemesia(25.7%), house dust mites(21.4%),house dust(14.2%),dog and catfur(10%). In all the allergens, inhaled allergens detection rate was higher, accounting for54.3%.Food allergens accounted for11.4%.Conclusion1.Respiratory tract infection and inhaled allergens were the most common causes lead toasthmatic exacerbation.2.Older patients were more likely to cause acute asthma attacks because of respiratoryinfections. In young group and middle group,more patients led to asthmatic exacerbation beause of inhaling allergens.3. Dust mites, artemesia, mould, house dust, dog and cat fur may be the common allergensled to asthmatic exacerbation in local.4.Positively preventing the respiratory tract infection, keeping out of allergens could reduceasthma exacerbation frequency and improve outcomes in patients with asthma.
