What are the symptoms of bronchitis?

Bronchitis can cause symptoms such as cough, sputum production, asthma, and recurrent infections.

1. Cough. After bronchitis, the most obvious symptom is coughing. The cough is more pronounced in the morning when the temperature is cooler, and the cough is milder during the day.

In summer and fall, cough symptoms lessen or disappear. If chronic bronchitis is more severe, the cough will be more severe throughout the year, and the cough will be worse in the winter and spring.

2. Coughing up phlegm. Patients with chronic bronchitis will have a sputum cough, which is usually white foamy mucus. In general, there is more phlegm after waking up in the morning. If you have a cold, the phlegm will also increase. Some patients are so sick that they have blood in their sputum.

3. Asthma. When patients with chronic bronchitis are severely ill, they may be complicated by respiratory infections. At this point, asthma symptoms appear.

4. Recurrent infection. In patients with chronic bronchitis, respiratory infections often occur in the cold season of winter and spring, especially in the elderly and frail patients. Patients with bronchitis should first of all, pay attention to drinking plenty of water and rest.

Patients with bronchitis have significant cough, sputum production, and fatigue. Therefore, one should pay attention to drinking plenty of water and resting more. In addition, an intravenous drip with some antibiotics or antivirals is required**.

If there is a bacterial infection, antibiotics can be given intravenously**. For example, if you are not allergic to a cephalosporin, ceftriaxone sodium may be used. If the infection is viral, ribavirin can be given intravenously or Tamiflu taken by mouth.

Patients often have cough and sputum production as the main manifestations. Among them, chronic bronchitis mostly has a slow onset, and the patient has a long course of disease, and repeated acute attacks are aggravated. Patients with acute bronchitis have an acute onset and mild symptoms.

1. Symptoms Systemic symptoms are generally mild, with fever, about 38, and more than 3-5 days to normal. Cough and sputum production, first dry cough or a small amount of mucinous sputum, and then can turn into mucopurulent or purulent, the amount of sputum increases, the cough is aggravated, occasionally there is blood in the sputum, the cough can last for 2-3 weeks before disappearing, if it is not healed, it can evolve into chronic bronchitis. If the bronchi spasm, there may be varying degrees of shortness of breath and a feeling of tightness behind the hemisternum.

2. Body Body: There are not many body bodies, breath sounds are often normal, and scattered dry and wet rales can be heard in both lungs. The rales are not fixed and may decrease or disappear with coughing.

Laboratory tests.

There is no significant change in the white blood cell count and differential in the peripheral blood. In severe bacterial infection, the total number of white blood cells and neutrophils is elevated, and sputum cultures can detect the causative organism. On chest x-ray, most of the findings are normal or only have thickened lung markings.

It should be differentiated from the following diseases:

First, the epidemic ** onset is abrupt, fever is high, systemic poisoning symptoms such as body aches, headache, fatigue and other obvious and local respiratory symptoms are mild. There is often an epidemiological history and can be differentiated by virus isolation and serologic testing.

2. Acute upper respiratory tract infection Nasopharyngeal symptoms are obvious, generally including cough and sputum, and there is no abnormal body in the lungs.

3. Other diseases such as bronchopneumonia, tuberculosis, lung cancer, lung abscess, measles, whooping cough and other diseases can be accompanied by symptoms of acute bronchitis, which should be examined in detail for identification.

**。1. General** Rest, keep warm, drink plenty of water, and replenish enough calories.

2. Antimicrobial drugs** Antimicrobial drugs are selected according to the pathogen of infection and drug susceptibility test**. In general, drugs such as macrolides, penicillins, cephalosporins, and quinolones can be used before a positive result for pathogenic bacteria is obtained. Most patients can take oral antimicrobials, and those with more severe symptoms can be given intramuscular injections or intravenous infusions.

3. Symptomatic** For cough without phlegm, dextromethorphan, pentovereline (cough must be clear) or codeine can be used. If the cough has phlegm and is not easy to cough up, ambroxol hydrochloride and bromhexine can be used, etc., and it can also be nebulized to help phlegm. Chinese patent medicines can also be used for cough and phlegm medicines.

In the case of bronchospasm, antiasthmatic drugs such as theophylline and receptor agonists can be used. Fever can be treated with antipyretic analgesics.

Prevention Strengthens the body and prevents colds. Improve the labor and health environment, prevent air pollution, and purify the environment. Remove lesions in the nasopharynx, larynx, and other parts.

Bronchitis, generally with cough and sputum as the main clinical manifestations, of which acute tracheobronchitis generally has a rapid onset, usually mild systemic symptoms, fever and chronic bronchitis, generally slow onset, long course of repeated acute attacks, and aggravation.
