What does bronchospasm mean?

Bronchospasm is a very common respiratory disease in normal times. It is usually caused by bronchitis, allergies, nerve stimulation, etc. However, when bronchospasm occurs, it must be treated in time. However, during treatment, the cause must be found out, and then symptomatic treatment should be given according to the cause. Only in this way can the symptoms of cough and asthma be effectively relieved. The following is a detailed introduction to what disease bronchospasm is.

What does bronchospasm mean?

Bronchospasm is a functional state of the bronchi caused by a variety of diseases and is not an independent disease. Bronchospasm is usually caused by upper respiratory tract infection or its repeated infection, which leads to tracheal (bronchial) mucosal lesions, making it sensitive to external stimuli and causing cough and asthma. In addition, certain allergens and nerve irritants may cause bronchospasm. Find the primary disease that causes bronchospasm, treat it according to the cause, relieve bronchospasm symptomatically, and alleviate cough and asthma symptoms.

Causes and common diseases

Upper respiratory tract infection or its repeated infection leads to tracheal (bronchial) mucosal lesions, which makes the patient sensitive to external stimuli and causes cough and asthma. In addition, smoking, certain allergens, and nerve stimulation may cause bronchospasm. Common diseases:

1. Chronic bronchitis in the elderly

Wheezing, hypercapnia, dyspnea, coarse breath sounds, low breath sounds, rales, etc.

2. Ammonia poisoning

Nausea and vomiting, cyanosis, fatigue, laryngeal edema, dyspnea, etc.

3. Hay fever

Nasal congestion, nasal congestion and reflex headache, runny nose, itchy skin, bronchospasm, etc.

4. Nitrogen dioxide poisoning

Nausea, miliary shadows in both lungs, blood in sputum, wheezing, bronchospasm, etc.

5. Small Intestinal Carcinoid

Valve thickening, cyanosis, fatigue, abdominal pain, diarrhea, dyspnea, etc.

6. Acute attack of bronchial asthma

Cough, chest tightness, wheezing, and difficulty breathing.

Differential Diagnosis

1. Influenza

The onset is acute, with an epidemiological history. In addition to respiratory symptoms, systemic symptoms such as fever and headache are obvious, and virus isolation and positive complement fixation tests can be used for identification.

2. Upper respiratory tract infection

Symptoms such as nasal congestion, runny nose, and sore throat are obvious, but there is no cough or sputum, and no abnormal signs in the lungs.

3. Bronchial asthma

Patients with acute bronchitis accompanied by bronchospasm may experience wheezing and wheezing, which should be differentiated from bronchial asthma, the latter of which has symptoms and signs such as paroxysmal dyspnea, labored expiratory breathing, wheezing, full lung wheezing, and orthopnea.

Treatment principles

Find the primary disease that causes bronchospasm, treat it according to the cause, relieve bronchospasm symptomatically, and give muscle relaxants to reduce the increase in respiratory impedance caused by choking and coughing. The use of drugs such as β2 agonists is relatively safe. Inhaled administration has the same effect as parenteral administration, with fewer side effects. Hormones can relieve bronchospasm.
