First of all, you should know that this is an irreversible 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, strengthen physical exercise, enhance physical fitness, improve cold tolerance and physical resistance.

Prevention of colds: Avoiding colds can effectively prevent the occurrence or acute attack of chronic bronchitis. 2. Diet adjustment: The diet should be light and avoid spicy meat.

It will aggravate the condition, and the gas emitted by the coal stove at home will induce cough and asthma. Kitchen rooms should be ventilated or equipped with range hoods to keep the indoor air fresh. Parasites, pollen, fungi, etc. Can cause bronchial specific allergic reactions, so the indoor and outdoor environment should be kept clean and hygienic, and dirt should be removed in time to eliminate allergens. 5.
