Most coughs and phlegm start with a cold, and most of them are viral in the early stage, so there is no special medicine. The frequency is better understood, but the degree is more difficult to explain: generally speaking, a continuous cough (each cough is several times in a row) is more serious than a single cough. As the disease worsens, you can feel that the cough is coming from the trachea or deeper, and the sound will be muffled, which often indicates that the lesion has reached the trachea. The main observation of coughing sputum is the stickiness of the sputum. Young children do not spit out sputum, and the sputum they cough into their mouths is swallowed into their stomachs, so parents cannot see the sputum. On the contrary, if the phlegm is still in the airway after 5-6 coughs, it means that the phlegm is sticky. When the condition is not very serious, the doctor’s physical examination will not be able to detect anything. At most, the breath sounds will be a little coarse, and a little phlegm sound will be heard if the parents can give more detailed information, which can be used as a reference for the doctor’s treatment. At least I pay attention to the parents’ accounts. The recovery of cough and sputum in young children is generally slow, especially in children with allergies, so parents should not be too anxious and focus on observing the changes in the condition, as the disease is always a dynamic process that either gets better slowly or gets worse slowly. The cough syrup and cough syrup for children are very different from those for adults, with very few coughing ingredients and mainly phlegm-suppressing and anti-inflammatory, and the lung power cough combination is a safe Chinese medicine. The main purpose of using phlegm medicine is to make the phlegm diluted and easy to cough out, usually about 5 days, you will obviously feel the phlegm “loose” when coughing (refer to the previous expression), and a few will also feel more phlegm at the same time, if you feel more phlegm, phlegm medicine should be stopped, to this stage mainly to The main purpose of this stage is to promote the discharge of phlegm or to reduce the amount of phlegm. Infants have poor coughing ability and phlegm is not easily eliminated, so you can use back patting to promote the flow of phlegm, the specific method: put your fingers together, bend your palms together slightly to form a slight depression in the palm part, gently pat your back so that there is a resonance effect, you need to pat in different positions, upright, lying down, lying on your side, 5-10 minutes each time. The main reason is that the airway is prone to allergic inflammation (antibacterial agents are ineffective), plus the small caliber of the airway and the underdevelopment of the cartilage around the airway in young children, which can easily lead to airway spasm and mucus production. It is necessary to add some anti-allergic drugs and bronchodilators. The use of antimicrobial agents: If it comes to tracheitis, bronchitis, antimicrobial agents should still be used, often seen in the clinical treatment of untimely development process pneumonia. The antimicrobials should be used in sufficient quantity, including the course of treatment, the dose is too small, can not completely kill the bacteria, but easy to produce drug-resistant bacteria, now commonly used oral cephalosporins, the recommended dosage on the manual is generally small, it is recommended to use the upper limit of the dosage in accordance with the manual.
