Pediatric bronchitis is usually preceded by symptoms of upper respiratory tract infections, followed by coughing as the main clinical manifestation, first dry cough, followed by sputum. So coughing up phlegm can only show that the bronchitis has progressed, it may be improved, or the disease may be aggravated. Improvement of pediatric bronchitis, generally manifested in the child’s spirit of appetite gradually returned to normal, coughing and asthma and other clinical manifestations significantly reduced, body temperature decreased and returned to normal, in addition, vomiting and diarrhea, lung rales and other signs and symptoms will also be reduced or disappeared. If the child can not cough up sputum, it will affect the recovery of the disease, therefore, in the treatment of bronchitis, generally do not recommend the use of cough suppressants, so as not to affect the sputum coughing out and aggravate the condition, only in the sputum thick and can not be coughed up, then consider the use of expectorant drugs such as aminobromine oral solution. If the child has a high fever, or high fever does not go away, accompanied by depression, loss of appetite and other symptoms, you need to actively consult the nearest hospital, identify the cause of the disease, and follow the doctor’s instructions for reasonable treatment.
