In severe cases, the symptoms may be accompanied by congestive heart failure, respiratory failure, hypoxic encephalopathy, and water and electrolyte disturbances. The general temperature does not exceed 38.5℃ and the duration of the disease is 1~2 weeks. 2, what are the symptoms of pediatric bronchitis?

Blood gas analysis shows hypoxemia as well as decreased or increased partial pressure of arterial blood carbon dioxide. 2, patting the back when the child coughs and coughs up sputum, indicating an increase in bronchial secretions, in order to promote the smooth discharge of secretions, nebulized inhalants can be used to help expectoration, 2-3 times a day, 5-20 minutes each time. In the case of infants and young children, in addition to patting their backs, they should also be helped to turn over once every 1-2 hours to keep the children in a semi-recumbent position, which is favorable to the discharge of sputum. If the body temperature is below 38.5 degrees Celsius, there is no need to give antipyretic drugs, but mainly to treat the cause of the problem. If the body temperature is high, older children can be given physical cooling, that is, wet compresses with cold towels on the head or bath with warm water, but young children should not use this method, if necessary, the application of drugs to lower the temperature. 4, point rubbing breast root doctor one hand to hold the sick child, the other hand with the index finger or middle finger, respectively, placed under the sick child’s nipples two minutes outside, point rubbing 1 minute.

Sulfonamides can be used with cotrimoxazole, 20 mg per kg of body weight per day, divided into two oral doses.

Some children are allergic to sulfonamides. After the use of rash, exfoliative dermatitis, etc., if encountered with a history of allergies can not be used.

Phlegm-suppressing drugs can be used as phlegm-suppressing tablets, 1/2 a l tablet each time, 3 times a day.
