I won't write some drugs and remedies here because there are risks. It is recommended to find a specialized hospital for a careful examination. 1. Children who rest and keep warm should reduce their activities and increase their rest time. When lying in bed, their heads and chests should be slightly raised to make their breathing smooth. Indoor air is fresh, maintain proper temperature and humidity, and avoid convection wind. 2. Ensure adequate water and nutrition supply, encourage children to drink plenty of water, and replenish them intravenously when necessary. Give a digestible and nutritious diet, and it is advisable to eat liquid or semi-liquid when you have a fever. 3. Keep your mouth clean. Because children have fever, cough and sticky phlegm, severe cough can cause vomiting, so oral hygiene should be maintained to increase comfort, stimulate appetite and promote the excretion of toxins. Infants can feed proper amount of boiled water to clean their mouths after eating. Older children should rinse their mouths in the morning, after meals and before going to bed. 4. Fever care If the fever is not high, no special treatment is needed. Physical cooling or drug cooling measures should be taken to prevent convulsions (refer to the nursing of high fever in the second section of this chapter). 5. Observe the nature of respiratory secretions and whether they can effectively cough up sputum, so as to guide and encourage children to cough effectively; If the sputum is sticky, the humidity of the sick room can be appropriately increased, and the indoor temperature can be kept at about 60% to humidify the air and dilute the secretions. Ultrasonic atomization inhalation or steam inhalation can also be used; For children with cough weakness, it is advisable to change positions frequently and pat the back, so that respiratory secretions can be easily discharged and inflammation can be dissipated; If secretions affect breathing more, use aspirator to expel phlegm in time to keep the respiratory tract unobstructed. People with cough and asthma can take oxygen. 6. Strengthen nutrition and health education, take appropriate outdoor activities, exercise, and enhance the adaptability of the body to temperature changes. Increase or decrease clothes according to the temperature change to avoid getting cold or overheating. During the epidemic of respiratory diseases, don't let children go to public places to avoid cross-infection. Actively prevent malnutrition, rickets, anemia and various infectious diseases, vaccinate on time, and enhance the body's immunity.
