I. What is asthma a disease? Asthma is a chronic disease. The clinical manifestations are recurrent episodes of expiratory dyspnea with croup, chest tightness and cough. Most of the symptoms can be relieved on their own or with treatment. If prolonged, attacks can lead to narrowing of the airways, resulting in irreversible airway obstruction. Airway hyperresponsiveness is a phenomenon in which the tracheobronchial tubes overreact to various physical, chemical or biological stimuli; and cause asthma attacks; it is the main pathophysiological feature and diagnostic basis of bronchial asthma and is due to the persistence of chronic inflammation of the airways in asthma. The bronchial mucosa epithelium is damaged and the sensory nerve endings within the epithelial tissue are exposed and are particularly sensitive to external stimuli. Second, the current status of asthma control in children. Asthma is one of the most common chronic diseases of the pediatric respiratory system in the world, and the results of the epidemiological survey of childhood asthma in China in 2002 showed that the number of children with asthma reached 10 million nationwide, an increase of 64.8% compared with 10 years ago, and it has become a serious social problem, which not only seriously affects the life, learning and growth of children, but also brings heavy economic and It has become a serious social problem. The incidence of asthma will increase year by year as the environmental problems faced by human beings become more and more serious. However, due to the long course of treatment and the fact that most of the treatment is carried out at home, many people lack the relevant knowledge and often fail to adhere to formal control and preventive measures, resulting in recurrent asthma attacks and persistent treatment. Third, the general knowledge of asthma prevention. Some children can find the corresponding allergens, and if they can avoid contact with these specific allergens, they can effectively prevent asthma attacks. Common asthma-causing factors include: 1, dust mites, cockroaches, fungi, animals, pollen, etc.; 2, drugs and food additives; 3, respiratory tract infections; 4, passive and active smoking; 5, exercise and hyperventilation; 6, emotional overexcitement, allergic rhinitis and gastroesophageal reflux, etc. IV. How to diagnose asthma? Asthma has many different causes and manifestations, and many other diseases can also manifest symptoms of asthma; wheezing symptoms can easily appear in infancy and early childhood due to the anatomical and physiological characteristics of children; therefore, the diagnosis of asthma needs to be made carefully, especially in infants and children under 5 years old. The first step is to clarify the presence of an asthma attack and, after excluding other diseases, to look for allergens if possible and try to avoid exposure. The diagnosis of asthma should also be graded according to the degree of the attack, and then the corresponding treatment should be given according to the graded level. V. Specific treatment of asthma. The asthma prevention and treatment guidelines developed by the World Health Organization and our asthma control institutions are the most authoritative programs available. The treatment of asthma is given according to the exacerbation or interval of asthma, respectively, control treatment and preventive treatment. The choice of specific treatment plan depends on the specialist. After remission, it is also necessary to be guided by a doctor to gradually reduce the dosage and not to stop the medication on your own. In other words, it is necessary to follow the guidelines for stepwise treatment. Sixth, how to self-monitor asthma patients. Since the condition of asthmatic children varies greatly on an individual basis, treatment measures must be taken according to the actual situation of each child; this requires that parents should configure a peak flow meter for all asthmatic patients over 5 years old, in addition to noting down the usual attacks and medications used. This simple instrument can help you get a good grasp of the condition, provide the most reliable basis for the doctor to increase or decrease the medication, and foretell the asthma attack in advance, etc. Seven, the goal of asthma control. With proper treatment, most asthma patients can be completely controlled or even clinically cured, especially in children. Therefore, through the joint efforts of parents and doctors, you can keep your child away from asthma.
