Cough what symptom? Let's talk about it

Cough what symptom?

It is characterized by severe cough, one cough after another, a cough can be more than ten to dozens, lasting for quite a long time. When coughing, the face and neck are red, and the breathing is affected. Deep breathing is often required after the cough is stopped. Severe cough often causes glottic spasm, which is similar to the sound of chicken crow,

Persistent and severe cough often causes retching. After a while of coughing, it is quiet for a while and then starts coughing again. It can cause tongue frenulum ulcer and subconjunctival hemorrhage in children.

If there is obvious spasm cough, peripheral blood count, white blood cell and lymphocyte classification are significantly increased, the clinical diagnosis of pertussis can be made. In addition, pertussis can be diagnosed by positive bacterial culture, serological immunology and PCR.

matters needing attention

In the treatment of cough, the first thing is to find out the cause of the disease. On the basis of the treatment of the primary disease, we should choose appropriate antitussive and expectorant drugs and pay attention to nursing. When the respiratory tract mucosa is stimulated by foreign bodies, inflammation, secretions or allergic factors, it can cause cough reflexively, which helps to eliminate the foreign bodies or secretions invading the respiratory tract from the outside world and eliminate the respiratory tract stimulating factors. For intractable cough, central antitussive can be selected to achieve the goal of relieving cough. When the amount of expectoration is large, antitussive drugs can not be used alone, but should be combined with expectorant drugs.
