What should bronchitis pay attention to? What time is the attack?

Bronchitis refers to chronic nonspecific inflammation of trachea, bronchial mucosa and its surrounding tissues. The clinical manifestations are long-term cough, expectoration or wheezing, and repeated attacks. Chronic cough, expectoration or wheezing lasts for 3 months every year for more than 2 years, and often occurs repeatedly in cold season and climate change. Other cardiopulmonary diseases can be ruled out, and some patients can develop obstructive emphysema and chronic pulmonary heart disease.

In order to prolong the remission period, reduce the recurrence and prevent the further development of the disease, patients and their families should pay attention to prevention and nursing.

1. Actively control infection: choose effective antibacterial drugs according to doctor's advice in acute stage. Commonly used drugs are: compound sulfamethoxazole, potent toxin, erythromycin, penicillin and so on. When the treatment fails, you can also choose drugs that the patient has never used or used less, such as midecamycin, spiramycin and cephalosporin. After acute infection control, stop using antibacterial drugs in time to avoid side effects caused by long-term application.

2. Promote expectoration: Patients in acute phase should use antitussive and expectorant drugs while using antibacterial drugs. For elderly patients who are too weak to expectorate or patients with a large amount of sputum, expectoration should be the main treatment, and strong antitussive drugs should not be used, so as not to inhibit the central nervous system from aggravating respiratory inflammation and lead to the deterioration of the condition. Helping critically ill patients to change their posture regularly and gently massage their chest and back can promote the discharge of sputum.

3. Maintain good household hygiene, fresh indoor air circulation and a certain humidity, control and eliminate all kinds of harmful gases and smoke, quit smoking habits and pay attention to keep warm.

4. Strengthening physical exercise, strengthening physical fitness, improving respiratory resistance, preventing upper respiratory infection and avoiding inhaling harmful substances and allergens can prevent or reduce the occurrence of this disease.

5. In the climate change and cold season, pay attention to increase or decrease clothes in time to avoid catching a cold and prevent the flu. Pay attention to observe the changes of the disease and master the law of the disease, so as to take measures in advance. If the patient has symptoms such as dyspnea, purple lips and nails, edema of lower limbs, trance and drowsiness, he should be sent to the hospital for treatment in time.
