What is pediatric bronchitis?

Pediatric bronchitis, the name of the disease is "bronchiolitis." The pathogen of bronchiolitis is mainly respiratory syncytial virus, which can account for 80% or more; other orders are adenovirus, parainfluenza virus, rhinovirus, influenza virus, etc.; a few cases can be caused by Mycoplasma pneumoniae, after infection, small Capillary congestion, edema, increased mucus secretion, and necrotic mucosal epithelial cells shedding and blocking the lumen, leading to obvious emphysema and atelectasis. It usually affects the alveoli, alveolar wall and interstitial lung, so it can be considered a special type of pneumonia.

What is pediatric bronchitis?

Bronchiolitis, different from general bronchitis or bronchitis, clinical symptoms like pneumonia, but mainly wheezing, the disease mostly occurs in children under 2.5 years old, 80% within 1 year old, most of them are less than 6 months Children. Typical bronchiolitis often occurs in the upper respiratory tract infection 2 to 3 days after the onset of persistent dry cough and fever, body temperature in the middle and low fever, the onset of wheezing is characterized by 2 days after the onset of wheezing On the 3rd, the breathing was significantly increased. The breathing increased significantly, reaching 60 to 80 times per minute, accompanied by exhalation prolongation and Hohhot gasthoracic throat; severely ill children showed nasal discharge and "three concave signs". "(ie, there is a supraclavicular fossa when inhaling, a sternal upper fossa and a depressed upper abdomen), pale face, blue bruises, or cyanosis, children often irritated, more than stunned; more severely ill children may have heart failure or Respiratory failure, most cases can be relieved after treatment, and very few deaths occur.


Pediatric patients should be sent to hospital for treatment after the onset of illness. Because bronchiolitis is caused by viral infection, it is generally not necessary to use antibiotics in the early stage of the disease. Such as suspected secondary bacterial infection in the late stage of the disease can be treated with antibiotics, treatment is mainly symptomatic treatment, can be summarized as "stationary cough", in addition, good care is also very important, especially pay attention not to disturb the child, make it quiet rest, indoor To maintain a certain degree of humidity, severely ill children can be inhaled with aerosol, and suck in time to keep the airway open.


The majority of bronchiolitis is good, and the course of disease is usually 5 days to 9 days. However, it should be noted that children with capillary bronchitis are prone to asthma in the future. Through the epidemiological investigation of childhood asthma in children and follow-up of children with bronchiolitis in infants, 20% to 40% of them are found. Later, it develops into asthma in children. Therefore, it is necessary to actively prevent bronchiolitis to reduce the incidence of asthma.
