Cough usually lasts for 7 to 10 days, sometimes for 2 to 3 weeks, or recurrent. If not treated properly, it can cause pneumonia, white blood cells are normal or slightly lower, and those who are elevated may have secondary bacterial infections.

Children with healthy bodies rarely have complications, but in children with malnutrition, low immune function, congenital respiratory malformations, chronic nasopharyngitis, and rickets, they are not only prone to bronchitis, but also complicated by pneumonia, otitis media, laryngitis, and parasinusitis. .

Causes of bronchitis in infants

Why do babies get bronchitis easily? Compared with adults, babies (especially infants under one year old) have the following different characteristics:

1. The diameter of the trachea is small, so the air resistance is large.

2. In terms of aerodynamics, the percentage of air resistance in the lungs of the children's peripheral lungs is relatively large, so if there is something wrong, breathing will be very laborious.

3. The development of cartilage and smooth muscles of the trachea is still not sound. Once there is a problem, it is easy to collapse, resulting in increased respiratory resistance.

4. The elasticity of the entire thorax and the pectoral muscles of children are relatively fragile, which makes them more likely to have difficulty breathing.

Therefore, if infants and young children have bronchitis, symptoms will be particularly serious.

Characteristics of bronchial inflammation in infants

(1) It is more common in children under 1 year old, especially in infants under 6 months.

(B) the disease can occur all year round, but more common in winter and spring.

(3) The onset is relatively rapid, with early symptoms of colds, such as cough and sneezing, and the cough worsens after 1 to 2 days, and there is paroxysmal drowsiness [1] Difficulty, wheezing, pale complexion, cyanosis of lips, tricuspid sign, lung Early signs of wheezing are the main signs, followed by wet sounds. Severe symptoms can be associated with congestive heart failure, respiratory failure, hypoxic encephalopathy, and water and electrolyte disorders. Generally, the body temperature does not exceed 38.5 ° C, and the course of disease is 1 to 2 weeks.

(4) The white blood cells are usually normal or slightly increased. Blood gas analysis showed that hypoxemia and arterial blood carbon dioxide partial pressure decreased or increased. Chest x-rays showed thickened lung texture, enhanced bilateral lung transparency, or small shadows and atelectasis. Conditions can be used for rapid diagnosis of respiratory secretion virus to determine the virus type.

When suffering from bronchitis, children often have varying degrees of fever, cough, loss of appetite or vomiting, diarrhea, etc. Smaller children may also have wheezing, wheezing and other symptoms of bronchiolitis. Although a small number of children may develop bronchial pneumonia, most of the children are relatively mild. They are mainly treated and treated at home with medicines. Parents should follow the doctor's advice to give the children medicine and time home care:

Therefore, parents should add or remove clothing to children in time with temperature changes, especially to cover children during sleep. Good quilt to keep your body temperature above 36.5 .

Second, feed more water: children with bronchitis have varying degrees of fever, water evaporation is large, you should pay attention to feed more water to children. It can be replenished with sugar water or sugar salt water, or with rice soup or egg soup. The diet is mainly semi-liquid to increase the body's moisture and meet the needs of the body.

Third, adequate nutrition: children with bronchitis have a large consumption of nutrients, coupled with fever and bacterial toxins affecting gastrointestinal function, digestion and malabsorption, so the nutritional deficiency of children should not be ignored. In this regard, parents should take a small number of multiple meals method for children, giving a light, adequate nutrition, balanced and easy to digest and absorb semi-liquid or liquid diet, such as porridge, cooked noodles, egg custard, fresh vegetables, fruit juice and so on.

In order to promote the smooth discharge of secretions, aerosolized inhalants can be used to help expectorants, 2-3 times a day, 5-20 minutes each. If it is an infant, in addition to patting the back, it should also help to turn over every 1 to 2 hours to keep the child in a semi-recumbent position to facilitate the discharge of sputum.

V. Antipyretic; children with bronchitis usually have moderate to low fever. If the body temperature is below 38.5 ° C, antipyretics are generally not needed, mainly for the treatment of the etiology and fundamentally solving the problem. If the body temperature is high, older children can be physically cooled, that is, wet the head with a cold towel or wipe with warm water, but children should not use this method, if necessary, use drugs to cool down.

6. Maintain a good family environment: The child's room should be warm, well ventilated and well-lit, and there must be some humidity in the air to prevent excessive drying.
