The definition of asthma
Asthma is a recurring situation in which certain stimuli Airways narrow for a while so that makes a person breathing.
Although asthma can occur at any age, but usually occurs in children, particularly in children from the age of 5. Some children suffer from asthma to their adulthood. Most children with asthma can still interact with their environment, but if an asthma attack. Only some children who are resistant to drugs to prevent asthma and need daily to be able to do sports and play normally.
For unclear reasons, children with asthma are usually in response to specific stimuli (triggers). There are many factors that cause asthma attacks, but each child usually causes (triggers) is different. Several factors trigger asthma attacks, ie indoor irritants, such as strong odors, irritant fumes (perfume, tobacco smoke); contamination outside, cold air, exercise; emotional disturbance; respiratory infections due to viruses, and various materials that make children have allergies, such as animal dander, dust, pollen and mold
All these calls produce a similar reaction. certain cells in the airways free agents. These chemicals cause the airways to become inflamed and swollen and stimulate the muscle cells in the airway walls to contract. Reduce stimulation with chemicals to increase the production of mucus in the airways, makes pouring cells lining the airways and increase the muscle cells in the airway wall. Each reaction is called small airways suddenly (asthma attacks) .In most children, airway back to normal between asthma attacks.
Doctors do not fully understand why some children suffer from asthma, the number of known risk factors. A child with one parent with asthma have an increased risk of 25% have asthma, if both parents have asthma, the risk increases to 50%. Children whose mothers smoked during pregnancy are more likely to develop asthma.
Children in urban areas are more likely to have asthma, especially if they come from lower socioeconomic groups. Although asthma affects a high percentage of black children compared to white children, the role of genetic influence on the increase in asthma is controversial because black children are also more likely to live in urban areas. Children are faced with high concentrations of allergens, such as dust or cockroach droppings, at a young age are more likely to suffer from asthma. Children who suffer from bronchiolitis at a young age often wheezing with advanced infection. Wheezing first sound can be interpreted as asthma, but children are not more likely to have asthma in adolescence.
When airways constrict in asthma attack, the child can be difficult breathing, along with his trademark sound wheezing. Wheezing is a loud noise that sounded high when the child breathes. Not all asthma attacks wheezing produce sound, however. Mild asthma, especially in young children, could only produce cough; some older children with mild asthma tend to cough only during exercise or when exposed to cold air.
Also, children with acute asthma may not wheeze because too little airflow to create noise. In acute asthma, breathing becomes difficult sincerely, sound wheezing usually becomes tighter, and the child is breathing rapidly and with greater effort, and ribs prominent when the child is breathing (inspiration). With acute attack, the child gasping for breath and sat upright, leaning forward. Sweating and pale skin or blue.
Children with frequent acute attacks sometimes slow development, but their growth is usually chasing another child in adulthood.
doctor suspected asthma in children who have recurrent wheezing, especially when family members are known to have asthma or allergies. Children Wheezing events can often be tested for other diseases, such as fiber or gastric esophageal recurring cysts. Older children sometimes stand lung function test, although Stout children lung function is normal between relapses.
One of half or more of children with asthma. Those with more severe were more likely to have asthma as a teenager.
Older children or adolescents can recognize asthma often use a peak flow meter, a small tool that records how fast a person can blow air to quantify airway diseases. This tool can be used to objectively assess the child’s condition.
Treatment of severe consists of opening the airways (bronchodilation) and stop inflammation. Various inhaled medicines to open the airways (bronchodilators). This particular example is albuterol and ipratropium. Older children and adolescents are usually able to use these drugs with metered dose inhalation device. Children older than 8 years old often find it easy to use the inhaler with spacer or buffer room installed. Infants and very young children can sometimes use spacer inhalation and infant size masks come.
Children who do not use inhalers may receive inhaled drugs at home through a mask attached to the nebulizer, a small tool that generates steam cure with compressed air. Tool inhalation and nebulizer are equally effective removal of the product. Albuterol can also be used with the mouth, although this activity was not much better than inhalation and are usually only used in infants who did not use a vaporizer. Children who are experiencing severe attacks can also give an oral corticosteroid.
Children with severe attacks were treated in hospital by providing a bronchodilator in a nebulizer at least 20 minutes at first. Sometimes the doctor uses injections of epinephrine, a bronchodilator, in children with severe attacks if they can not breathe well enough steam vaporizer. Doctors usually intravenous corticosteroids to children who have serious attack.
Children who suffer from mild asthma, with few attacks typically use medication only on the attack. Children with frequent or severe attacks also need to use drugs, even when they are not under attack.
Other drugs used, based on the frequency and severity of attacks in children. Children with few attacks that are not too bad usually use inhaled medications, such as cromolyn or nedocromil, or a low dose of inhaled corticosteroids daily to prevent attacks. These drugs prevent the discharge of substances harmful to the airways, and reduce inflammation. Preparing to use the old theophylline is a cheap option for prevention in some children.
Children with recurrent or severe also receive one or more drugs, including long-term bronchodilator such as salmeterol, leukotriene modifiers, such as zafirlukast or montelukast and inhaled corticosteroids. If these drugs do not prevent the onslaught, the child may have inhaled corticosteroids by mouth. Children who have experienced great development in training spirit usually bronchodilator dose just practice
