Asthma is a common chronic disease, currently about 200 million people worldwide suffer from asthma, and about 20 million patients in China. The disease seriously affects people’s quality of life, preventing them from enjoying a normal life, and in serious cases losing their ability to work, bringing heavy mental and economic burdens to patients and their families. More seriously, the current status of treatment for asthma patients in China is extremely unsatisfactory. In the 2000 Asia Pacific Asthma Survey, the results of a sample survey of asthma patients in three cities in China, Beijing, Shanghai and Guangzhou, showed that 43% of the patients’ sleep was affected by asthma, 22% of the patients missed work due to asthma, 49% of the children missed school due to asthma, 84% of the patients did not know that asthma could be treated or controlled by inhaled hormones, only 6% of the patients had used inhaled hormone therapy, 42% of the patients had never had a pulmonary function test, and only 10% of the patients had been treated with inhaled hormones. patients have never had a pulmonary function test, and only 15% of patients have been given a long-term treatment plan by their doctors. It can be presumed that the phenomenon of irregular asthma treatment is more serious in the vast rural areas. Therefore, the publicity and popularization of standardized treatment needs to be strengthened. As asthma is a bronchopulmonary disease, inhaled drugs can directly reach the lesion site with good efficacy and fast onset of action, therefore, inhalation therapy is recommended in the international standardized asthma treatment program. However, I found in my long-term clinical work that many asthma patients are not accustomed to or unwilling to apply inhalation therapy, one-sidedly believe that inhalation therapy has more side effects or is less effective than oral treatment, and blindly believe in some so-called secret recipes and prescriptions, resulting in some patients’ disease cannot be controlled or even aggravated, and some of them have serious side effects. There are two types of drugs most commonly used in the treatment of asthma. One category is bronchodilators, which are used to quickly relieve the symptoms of asthma, including β2 agonists (such as formoterol dry powder inhaler), anticholinergic drugs (such as ipratropium aerosol), and theophylline drugs (such as aminophylline). The other category is anti-inflammatory drugs, the most commonly used being glucocorticoids (hormones for short), which are currently the most basic and effective drugs for controlling chronic inflammation in the airways of asthma, blocking multiple links in the airway inflammatory response and preventing the progression of the disease. Whether in asthma exacerbation or remission, the airways of asthma patients have inflammatory lesions, and because this inflammation is not effectively treated with antibiotics, inhaled hormones (e.g., budesonide dry powder inhaler) should be preferred for treatment. In conclusion, the treatment of asthma is to use bronchodilators that provide rapid relief when chest tightness, breath-holding, wheezing and dyspnea occur on the basis of long-term inhaled hormones. When the symptoms are controlled, the bronchodilators can be discontinued, and the anti-inflammatory drugs must not be discontinued. If the symptoms are well controlled, the inhaled dose of anti-inflammatory drugs can be reduced every 3 months until the smallest effective dose is maintained for 1-2 years, and some patients even have to inhale small doses for life. Many patients have a fear of inhaled hormones. In fact, inhaled hormone therapy for asthma has been used clinically for decades, and as long as the drug is used correctly, side effects are minimal. On the contrary, irregular oral hormones (such as prednisone or dexamethasone) and so-called “secret formulas” containing hormones have obvious side effects. Why do many patients inhale drugs ineffectively? The key is not to master the correct method of inhalation. Statistics show that less than 10% of patients who learn how to use the inhalation device by reading the instructions are using it correctly. For patients who have been trained by doctors, the correct usage rate is 80%. Due to the incorrect method, many patients do not have any effect after using the medication and think that the medication is not effective. Doctors and nurses should instruct patients to use the inhalation device correctly, and instruct them to practice and imitate more until they really master it.
