Bronchitis-Causes, Symptoms And Bronchiolitis

What Is Bronchitis ?

Bronchitis is the name given to inflammation of the bronchitis the large air tubes to the lungs: in response to infection, the lining of the tubes becomes swollen, fluid-filled and engorged with blood. There are two distinct types of bronchitis: acute bronchitis, which is an infection; and wheezy bronchitis, which may be partly, or totally, caused by an allergy. Treatment of the two condition is quite different, so diagnosis is very important.

Causes

Any germ breathed in and carried down towards the lungs may settle in the bronchitis and cause infection. These air tubes may respond to this infection by becoming swollen, thus narrowing the diameter of the airway. Dead and dying infected tissue lining the bronchi will then be shed as sputum, more commonly knows as phlegm. The situation, however, is sometimes more complicated: the child may have inherited, possibly unknown to all, a tendency to asthma. And, if this becomes obvious only when the child has a cough or cold, his or her condition-may be temped by some doctors as wheezy bronchitis. Children do not suffer from the disease which in this, there is permanent bronchitis; in this, there is permanent bronchial damage due mainly to cigarette smoking. Nevertheless, bronchitis is commoner in children whose parent smoke. It is also more common in boys than in girls, in children who are overweight, or who live in crowded urban areas and in poor housing condition. A child may also be more prone to bronchitis if a member of his or her family suffer from asthma, eczema or hay fever.

Symptoms

Often, the first sings of bronchitis are those of a cold. But after a few days, the child develops a moderately raised temperature of 37.2° C to 37.8° C (99° F to 100° F), coughs, sounds chesty and may wheeze. In severe cases, the child may have difficulty breathing, and complain of tightness across the chest. Sucking in of the chest on breathing in, is a prolonged compared with breathing in, is a sign that the airway is obstructed. There may also be more obvious signs, such as coughing up a grayish white, yellow or green phlegm; however this is unlikely in a child under seven years old as younger children tend to swallow sputum. Fortunately, acute bronchitis is rarely severe and usually lasts about ten days, although there may be residual cough for some time. Wheezy bronchitis may last longer, occur repeatedly and eventually merge into typical asthma. If there is no wheeze, but after a week the cough gets much worse, then the child may have whooping cough.

Bronchiolitis

Between the ages of three and eighteen months, babies are prone to a related condition called bronchitis. The bronchioles are a smaller set of air tubes. This condition occur in epidemics every winter and is invariably caused by a virus (RSV). Symptoms are similar to bronchitis but the cough features less than the breathlessness and general difficulty in breathing; fine wheezes may be heard when the baby breathes out. Bronchiolitis is often very severe, with the baby becoming blue exhausted and unable to feed. Sometimes there is associated pneumonia and the heart is put under great strain. But with careful nursing in hospital, using oxygen, intravenous or stimulants, virtually all babies makes a complete recovery. READ MORE

Bronchitis-Complication, Treatment And Recovery

Complication

Apart from bronchitis, neither acute nor wheezy bronchitis is usually dangerous. Acute bronchitis may, however, be parents at the same time as acute larun-gotracheitis (inflammation of the voice box and windpipe) or may progress and develop into pneumonia.

Treatment

Sometimes an antihistamine or mild sedative is prescribed to be used particularly at night. Antibiotics are widely used, but often ineffective as acute bronchitis is often a viral infection or allergy. If wheezy is the main symptoms then the doctor may suspect that asthma is playing a part in the illness. If so, he may prescribe one of the many extremely effective drugs used to relax the muscles surrounding the bronchi and bronchi-oles, thus widening them and making breathing easier. The bronchi most widely used of these drugs are salbutamol and theophylline, given in the from of tablets, capsules or medicine. In other children, drug such as salbutamol are frequently given via a pocket aerosol spray. Children under the age of four find these sprays difficult to manage, so some family doctors and most hospitals use electrically driven nebulizers. In severe cases of wheezy bronchitis, steroid hormones may be usually prescribed in tabled from, but if the child is in hospital the first 48 hours of treatment, may be given intravenously. If there is evidence of a collapsed area of lungs, or of pneumonia, physiotherapy may be advised. This involves positioning the child so that main air tube from each area of lungs slopes downwards in turn. The chest is then vibrate and tapped to loosen phlegm and held clear it from the lungs.

Recovery

Acute bronchitis is not likely to be a repeated problem unless parents smoke a good deal in the house. Wheezy bronchitis may well be recurrent, and many of these children will eventually turn out to have asthma. Making the correct diagnosis is very important as in this condition anti-asthmatic drugs are extremely effective, whereas antibiotics and cough medicines are not. Asthma should be considered especially if either parent, grandparents, brothers or sisters have asthma, eczema or hay fever. Some doctors prefer not to use the world asthma: they fear it will distress parents because it implies a long-term problem. In fact, parents should not dread this diagnosis as the method of treatment currently available are remarkably effective.

Cough-Causes

What Is Cough ?

Cough are the very common problem in childhood and are usually a symptom of infections such as a cold, measles or whooping cough. The cough itself is a reflex action, designed to prevent anything other than air from entering the lungs. A cough clears the upper part of the breathing tube of phlegm, mucus or any inhaled foreign body. It is worth remembering that, if a child suddenly starts to cough with no other obvious signs of infection, a breathed-in foreign body, such a piece of food, may be the cause. But normally, cough clear up on their own and should not be dosed with strong medicines, unless prescribed by a doctor.

Causes

Most childhood cough starts as part of an obvious respiratory infection the commonest being a cold. A cold can be caught at any age from birth onwards and coughing is nearly always one of the symptoms. The infection of the cold can spread through the tubes which make up the lower respiratory tract. In the larynx, or voice-box, this can cause laryngitis. Infection of the trachea, or windpipe, will cause tracheitis, and infection in the lungs will cause bronchitis or pneumonia. Small children who are prone to bronchitis whenever they get a cold, may also develop wheezing. This can be diagnosed as wheezy bronchitis or, sometimes, as asthma. A cough may last for several weeks after a cold. In this case usually a noisy bark without any rattling noise and no sputum will be present. It will be worse at night when the child is lying down. This happen because, after a cold, the nose and sometimes which, during the day, can be cleared by blowing the nose, sniffing or swallowing (where the stomach can neutralized it harmlessly). At night time, however the discharge trickles down the back of the throat, irritates the entrance to the lungs, and sets off a reflex cough. The reflex prevents the discharge from entering the lungs and so prevents more serious problem arising. Sometimes, other factors, such as enlarged adenoids, a chronic infection of the sinuses or an allergy, can cause a similarly persistent discharge down the throat and so result in a long-lasting cough which is worse at night than in the day. Another cause is whooping cough which has once again become widespread as fewer children are being immunized against it. When it starts, the infection is often very like an ordinary cold but, gradually, the cough gets worse especially at night. Bouts of coughing, during which the child’s face goes red, followed by being sick or a characteristic whooping, make the diagnosis more obvious. Measles is another common cause of coughing. When a child first gets measles, he will suffer from a runny nose and a cough, and the eyes become pink. Small white spots inside the mouth appear followed by a rash on the body. A cough which starts suddenly, without any other signs of infection may be caused by a foreign body which has been breathed in and become lodged in one of the tubes leading to the lungs. Young children often put small toys in their mouths and can quite easily swallow sometimes or breathe it in through the nostrils. A child of any age can breathe in a small piece of food or a titbit such as a peanut. If such an accident happens, it is important to see a doctor any foreign body that remains in the lungs can cause serious infection. Another cough that has no signs of infection is the habit tic. A child who, for example, may have some emotional problem can develop a persistent, nervous cough. Whether or not the child has a habit tic will become apparent if the child stops coughing whenever happily occupied or asleep.READ MORE
