When September came, many parents cheered: 'The Divine Beast' finally started school!

　　However, the school season is also in autumn, which is a high incidence season of respiratory infection. One autumn rain and one cold. At this time, the temperature difference between morning and night changes greatly, which is the season when viruses and bacteria are easy to reproduce. However, children's resistance is weak. Some children are prone to respiratory diseases such as pneumonia due to poor physique or improper parental care.

　　When students start school, parents worry about whether children will cross infection in crowded and relatively closed classrooms

　　Pediatric pneumonia is the most common respiratory disease of children in China. It is characterized by acute onset, severe illness and rapid progress. It accounts for 65% of the diseases of hospitalized children in China, ranking first. The air in autumn and winter is dry. The most harmful part of autumn dryness is the lungs. Viral bacteria often cause upper respiratory tract infection, which then causes lung inflammation.

　　When we talk about pneumonia, especially when the COVID-19 epidemic has not abated, parents reveal various anxieties. Yes, pneumonia is the most worrying disease for parents, because infants are very susceptible to infection. Unlike neonatal pneumonia, pneumonia in infants is usually caused by bacterial or viral infection. Children with colds, chicken pox and other diseases are also prone to pneumonia. The severity of pneumonia complications is much higher than the symptoms of pneumonia itself. Severe pneumonia can cause heart failure in children, even death.

　　How to self check children's pneumonia?

　　1、Increased body temperature

　　By touching your forehead and measuring your body temperature, you can find your child's temperature changes. Most children with pneumonia have fever, and most of them are above 38 ℃. If antipyretic drugs are used, they can only temporarily subside. However, the duration of fever is not the only basis for judging pneumonia, and it needs to be judged in combination with other aspects.

　　2、Dyspnea

　　Suffered from infantile pneumonia, usually there will be more serious cough or asthma, dyspnea. If the child has cough, accompanied by rapid breathing, it is mild pneumonia; If there is rapid breathing and chest depression, it is severe pneumonia; If it is accompanied by inability to drink water and cyanosis, it is extremely severe pneumonia.

　　3、Mental impatience

　　If the child gets pneumonia, he will have some abnormal mental conditions, such as being often anxious, crying restlessly, or sleeping, and having a convulsion. If the child is in good spirits while having fever, cough and asthma, and can play and laugh, it indicates that the possibility of suffering from pneumonia is small.

　　4、Chest blister sound

　　When the room temperature is above 18 ℃, take off the child's coat, gently stick the ear to the chest wall on both sides of the child's spine, and listen carefully to see if there will be 'gurgling' or 'gurgling' sounds, which are called tiny blister sounds. This is the primary sign of lung inflammation.

　　What kinds of pneumonia do children have?

　　1、Bacterial pneumonia: it is the most common pneumonia, accounting for about 80% of pneumonia. Pathogens include gram-positive cocci such as Streptococcus pneumoniae, Staphylococcus aureus, Streptococcus hemolyticus, etc; Gram negative bacilli such as Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, Enterobacteriaceae, Acinetobacter, Haemophilus influenzae and anaerobic bacteria.

　　2、Viral pneumonia: including adenovirus, influenza virus, measles virus, cytomegalovirus, herpes simplex virus, etc.

　　3、Mycoplasma pneumonia: also known as primary atypical pneumonia and condensation positive pneumonia, it is caused by mycoplasma (MP) infection, showing interstitial pneumonia and bronchiolitis like changes, and its clinical manifestation is pulmonary inflammation of stubborn severe cough.

　　4、Pneumonia caused by other pathogens: including Rickettsia, Chlamydia pneumoniae, Toxoplasma gondii, parasites (such as Pneumoconiosis carinii, pulmonary hydatid, paragonimus), etc.

　　5、Other non infectious factors: such as radiation pneumonitis, lung injury and fibrosis caused by radiotherapy of tumor chest; Chemical pneumonia, caused by inhalation of irritating gas or liquid; Allergic pneumonia refers to pulmonary eosinophil infiltration caused by contact with allergen.

　　Prevention and rehabilitation of pneumonia in children

　　Academician Zhong Nanshan pointed out at the 3rd China Respiratory Leadership Forum that, at present, it is a prominent problem in the prevention and control of respiratory diseases in China to focus only on the treatment of acute attacks and neglect preventive treatment. Although pneumonia poses a threat to children's health and life, it can be prevented as long as it is actively prevented. In addition to strengthening immunity and preventing colds, environmental factors are also very important for the prevention of pneumonia in children! A quiet and tidy environment with appropriate temperature and humidity is conducive to the recovery of children's pneumonia. It is generally recommended that the room temperature should be kept at about 20 ℃ and the relative humidity should be 55-65% to prevent the respiratory secretions from drying, coughing up and cross infection.
