Bronchitis includes both infectious and non-infectious induced changes in the bronchial mucosa, resulting in excessive mucus secretion and reduced enzymatic activity of the tracheal mucosa epithelium due to the lack of negative ions, which has a great impact on the alveolar secretory function and the ventilation and air exchange function of the lungs. The main manifestations are: prolonged cough, spitting, and difficulty in breathing. What are the symptoms of pediatric bronchiectasis? 1. Clinically, the symptoms of pediatric bronchitis Pediatric bronchitis is mostly a symptom of an existing upper respiratory tract infection, followed by a cough as the main symptom. The frequent and deeper dry cough appears at first, and then gradually there are bronchial secretions. The cough usually lasts for 7-10 days, sometimes for 2-3 weeks, or is recurrent. The symptoms of pediatric bronchitis are mild with no obvious appearance of illness and generally no systemic symptoms. In infants and young children, the symptoms are more severe, they feel easily fatigued and their appetite for sleep is affected. Fever can be 38-39℃, occasionally up to 40℃, more than 2-3 days to subside. Even vomiting, diarrhea, abdominal pain and other gastrointestinal symptoms occur. Older children then complain of headache and chest pain, which are all symptoms of bronchitis. 2, from the examination and diagnosis of the symptoms of pediatric bronchitis in the chest can be heard dry, wet rosing, rosing or coarse or fine, mostly moderate wet rosing, the symptoms of pediatric bronchitis mainly scattered in the lower chest, occasionally can be limited to one side. After coughing up secretions, the rales may be temporarily reduced. Occasionally, the breath sounds may be reduced due to too much sputum accumulation in the bronchi, but they return to normal after coughing up the sputum. In severe bronchial disease, the breath sounds of both lungs are coarse, and there may be irregular scattered dry and wet rales and coarse mid-wet rales. However, it should be difficult to distinguish from the early stage of pneumonia. If deeper rales or twanging sounds are heard and the rales do not decrease significantly after coughing, pneumonia should be considered for chest X-ray to confirm the diagnosis, which are all symptoms of bronchitis. What is the most effective medicine for pediatric bronchitis? First, for bacterial bronchitis patients, you can use some antibiotic drugs for treatment, such as cephalosporin, penicillin, aspirin, etc. These are some of the antibiotic drugs that we usually eat, but there are drugs that need to be selected according to the actual situation of the patient, especially the use of penicillin. Second, bronchodilator drugs. For bronchitis can also be used some anticholinergic drugs, such as ipratropium bromide (ipratropium bromide), such as salbutamol or terbutaline, through quantitative inhalers, or for oral administration, for the more serious people can choose to carry out intravenous injection. Third, for patients with bronchitis can take some expectorant drugs, such as salbutamol hydrochloride for oral administration, if it is not easy for some patients to cough up sputum can use some drugs can be nebulized for inhalation, which can moisten the airways in favor of sputum discharge. There are many ways to treat bronchitis, each person’s condition is different, do not blindly use drugs, even if the same disease may not have the same effect, so in the treatment must be tailored to their own situation for treatment. In addition, you must pay attention to exercise in your daily life, appropriate exercise is conducive to the recovery of the disease.
