Clinical manifestations of bronchopneumonia in children

The health of children is what parents are most concerned about. I believe every parent would feel very uncomfortable when seeing their child get sick. Bronchopneumonia is also a common disease in children, which causes children to suffer a lot. Children are helpless and I really wish I could bear it for them. What are the clinical manifestations of bronchopneumonia in children? Come and have a look!

1. Predisposing factors

Pneumonia is easy to occur in infants and young children due to the physiological and anatomical characteristics of the respiratory system, such as narrow trachea and bronchial lumens, low mucus secretion, poor ciliary movement, poor development of lung elastic tissue, abundant blood vessels and easy congestion, vigorous interstitial development, small number of alveoli, low lung air volume, and easy obstruction by mucus. Infants and young children at this age are prone to infectious diseases, malnutrition, rickets and other diseases because their immune system defense functions have not yet fully developed. These internal factors not only make infants and young children prone to pneumonia, but also make the disease more serious. Infants under one year old have very poor immunity, so pneumonia can easily spread, fuse and extend to both lungs. For older children with stronger physical constitutions, the body's responsiveness gradually matures and the ability to localize infection increases, so pneumonia often presents larger lesions. If it is limited to one lobe, it is lobar pneumonia.

2. Pathogens

Any pathogen that can cause upper respiratory tract infection can induce bronchopneumonia, but bacteria and viruses are the main ones, among which Streptococcus pneumoniae, Haemophilus influenzae, and respiratory syncytial virus (RSV) are the most common. Generally, most bronchopneumonia is caused by Streptococcus pneumoniae, while other bacteria such as Staphylococcus, Streptococcus, Haemophilus influenzae, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa are less common. In recent years, there has been an increasing trend of Mycoplasma pneumoniae, Chlamydia and Haemophilus influenzae. The pathogens often invade through the respiratory tract, and a few enter the lungs through the blood.

When children are sick, they are very worried. What are the clinical manifestations of bronchopneumonia in children? We must understand that if a child shows this symptom, he or she must go to the hospital for examination and treatment in time. This way, the treatment can be timely, the treatment effect will be better, and the child will suffer less pain.
