Most patients with chronic bronchitis, for the most part, show no abnormalities upon lung auscultation. This means their breath sounds are relatively clear, without diminished or enhanced breath sounds, nor any dry or wet rales typically heard. This is the case for the majority of patients; however, a small number of patients during acute exacerbations might present with some dry or wet rales at the back or the base of the lungs. Moreover, these rales may disappear after the patient coughs, indicating that in chronic bronchitis, the sounds heard upon auscultation can change and are not constantly present. You might hear dry or wet rales one moment, and after the patient coughs or receives treatment, these sounds could potentially alleviate. Additionally, if a patient with chronic bronchitis starts to wheeze or develops asthma, they might exhibit sounds such as wheezing or prolonged expiration.

Chronic Bronchitis Nursing Measures

Chronic bronchitis is a chronic inflammation of the respiratory system, which tends to be prolonged and recurrent. For those suffering from this disease, it is primarily important to quit smoking, which is a crucial preventive measure against acute attacks of chronic bronchitis. It is also essential to control occupational or environmental pollution to avoid the irritation of harmful gases such as dust and smoke. Additionally, it is advisable to strengthen the body through regular exercise, enhance immunity, and increase cold resistance. It is recommended to wash the face with cold water all year round to enhance the skin's ability to prevent and fight diseases. During the flu season, getting a flu vaccine to prevent the onset of a cold, reinforcing dietary hygiene, and enhancing health education is also advised.

Chronic bronchitis etiology

The etiology of chronic bronchitis is not very clear at present, and it is now believed to be caused by the long-term interaction of various factors. The most closely related factors are harmful gases or particles that act on the respiratory tract for a long time, causing damage to some structures of the respiratory tract, such as cigarette smoke, fumes, dust, irritating gases, sulfur dioxide, nitrogen dioxide, etc. These physicochemical factors cause damage to the airways. Additionally, some infectious agents, such as bacteria, mycoplasma, or viral infections, along with some immune-related factors, are believed to play a certain role in the development of chronic bronchitis.

Causes of Chronic Bronchitis

The causes of chronic bronchitis are not yet very clear. It is currently speculated that it may be the result of multiple factors interacting over a long period. The factors most closely associated with the occurrence of chronic bronchitis primarily include smoking, cigarette smoke, dust, and irritants such as sulfur dioxide, nitrogen dioxide, chlorine, ozone, etc. Additionally, some infectious factors may also be somewhat related to the occurrence of chronic bronchitis, with the most common possibly being infections by mycoplasma, bacteria, or viruses. Furthermore, chronic bronchitis may be related to age, climate, and other factors. Overall, the triggers of chronic bronchitis are not very clear at present, and it is advised to eliminate these risk factors as much as possible if present.

What are the symptoms of chronic bronchitis?

Chronic bronchitis is also colloquially known as "old chronic bronchitis." From this name, we can tell that patients usually develop the disease slowly with a long duration, lasting for years, even decades. The symptoms, such as coughing and expectoration, can acutely worsen repeatedly. Most patients cough and produce phlegm mostly when indoors, particularly noticeable upon waking in the morning and also possibly at night. The phlegm is typically white, sticky, or serous and foamy; occasionally, it may be blood-streaked. During acute exacerbations of chronic bronchitis or when accompanied by an infection, pus-like yellow phlegm or green bloody sputum may appear. Additionally, a small number of patients may experience wheezing, also known as asthmatic bronchitis.

Can chronic bronchitis be treated?

Chronic bronchitis, commonly known as "chronic obstructive bronchitis," is treatable. The primary symptoms of chronic bronchitis are coughing and expectoration. If the disease occurs for more than three months each year, for two consecutive years, while excluding other organic diseases, chronic bronchitis can be diagnosed. Treatment for chronic bronchitis is divided into two parts. During acute exacerbations, which typically present with worsened coughing and expectoration, increased sputum volume, or the presence of purulent sputum and possibly accompanied by wheezing and fever, the main treatment is anti-infection. The primary medications for anti-infection are antimicrobial drugs, which include macrolides, quinolones, cephalosporins, etc. Additionally, treatment can be aimed at alleviating symptoms of coughing and expectoration and might include expectorants and cough suppressants, such as ambroxol. For wheezing, medications like aminophylline or nebulized treatments may be necessary. Most of the time, patients with chronic bronchitis are in a remission phase. The primary treatment here initially involves addressing known triggers, such as insisting smokers quit and minimizing exposure to dust or harmful gases at work. Chronic bronchitis patients are encouraged to exercise moderately, strengthen their physique, and prevent colds. For patients who experience repeated respiratory infections, vaccination or immune modulators, such as BCG, may be considered. Always follow a physician’s guidance regarding specific medication use.
