Recognizing the Symptoms of Asthma in Children and Treatment of Asthma
Asthma is a recurring illness in which certain stimuli cause the airways to narrow for a moment and make a person difficult to breathing.
Though asthma can occur at any age, unfortunately most often children from the age of 5 years are the victims of asthma. Some children even suffer from asthma until their adulthood. Most children who have asthma can still interact with its environment if not in the event of an asthma attack. However, there are a few children who are resistant to drugs daily to prevent asthma and do their normal routine activities.
For some unknown reasons, children with asthma are usually reacting to certain stimuli (triggers). There are many factors that cause asthma attacks, but apparently the causes (triggers) on each individual child is different. Several factors trigger asthma attacks namely indoor irritants such as strong odors, irritant fumes (perfume, tobacco smoke, pollution from outside: cold air, exercise; emotional disturbance; respiratory infections due to viruses, and various kinds of substances like animal dander, dust, pollen and mold which make children become allergic.
All of these triggers produce a similar reaction, certain cells in the airways release chemical substances. These substances 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 production of mucus in the airways, making the spilling of cells lining the airways, and widen the muscle cells in the airway wall. Each reaction is triggered to the smaller airways suddenly (asthma attacks). However in most children the airway will be back to normal in between asthma attacks.
Doctors do not fully understand why some children suffer from asthma, but a number of known risk factors. A child with one parent with asthma has an increased risk of 25% to have asthma, if both parents have asthma, the risk increased to 50%. Children whose mothers smoked during pregnancy are more likely to develop asthma.
Children in urban environments are more likely to have asthma, particularly if they come from lower socio-economic groups. Although asthma affects a high percentage of black children compared with white children, the role of genetic influence in the increase of asthma is controversial because black children are also more likely to live in urban areas. Also children at an early age are more likely to suffer from asthma due to high concentrations of allergens like dust or cockroach droppings. Children who suffer from bronchiolitis at an early age often wheezing with advanced viral infection which can also be interpreted as asthma, but children are unlikely than others to have asthma during adolescence.
When airways constrict during an asthma attack, the child have difficulty breathing accompanied by his trademark sound wheezing. Wheezing is a loud noise that sounded high when the child breathes. Not all asthma attacks wheezing produce sounds, however mild asthma, particularly in young children, could only produce a 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 of too little air flow to generate 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 attacks, the child gasping for breath and sat upright, leaning forward. Sweating and pale skin or blue. Children with frequent acute attacks sometimes have a slow development, but their growth is usually chasing another child in adulthood.
A doctor suspected the cause of asthma in children who have wheezing repetitive is particularly when family members are known to have asthma or allergies. Children who wheezing events can often be tested for other disorders, such as fiber or gastro esophageal recurrent cysts. Older children sometimes perform lung function tests, although the stout children lung function is normal between relapses.
One of half or more of children with asthma control. Those with more severe disease were more likely to have asthma as a teenager.
Older children or teenagers can recognize asthma often have to use a peak flow meter, a small tool that records how fast a person can blow air-to measure the level of airway disorders. This tool can be used as an objective assessment of the condition of the child.
Treatment of a severe attack consists of opening the airways (bronchodilation) and stops the inflammation. Various kinds of inhaled medications to open airways (bronchodilator). This particular example is albuterol and ipratropium. Older children and teenagers are usually able to use these drugs using metered dose inhalation device. Children older than 8 years or often find it easy to use inhalation with a spacer or buffer room installed. Infants and very young children can sometimes use a spacer when inhaled and infant size masks fitted.
Children who do not use inhalation devices can receive inhaled drugs at home through a mask mounted on a nebulizer, a small tool that generates steam cure using compressed air. Tool inhalation and nebulizer are equally effective at removing the drug. Albuterol can also be used with the mouth, although it was not much successful than inhalation, Albuterol are usually used only in infants who did not use the nebulizer. Children who are experiencing severe attacks can also be administered via oral corticosteroids.
Children with severe attacks were treated in hospital by providing a bronchodilator in the nebulizer at least every 20 minutes at first. Sometimes the doctor uses an injection of epinephrine, a bronchodilator in children with severe attacks if they cannot breathe well enough on the steam nebulizer. Doctors usually give intravenous corticosteroids to children who have severe attacks.
Children who suffer from mild asthma, with infrequent attacks typically use medication only during the attack. However children with frequent or severe attacks 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 infrequent attacks that are not too bad usually use inhaled drugs, such as cromolyn or nedocromil, or a low dose of inhaled corticosteroids daily to help prevent attacks. These drugs prevent the release of chemicals that harm the airways, and reduce inflammation. Usage of the old theophylline is an inexpensive option for prevention in some children.
Children with recurrent or more severe also receive one or more drugs, including long-term bronchodilator such as salmeterol, leukotriene modifiers, zafirlukast or montelukast, and inhaled corticosteroids. If these drugs do not prevent the onslaught, the child may require inhaled corticosteroids by mouth. Children who experienced great develop during exercise usually inhale a bronchodilator dose prior to exercise.
