chemical bronchitis
Introduction
Introduction to chemical bronchitis Chemical bronchitis is a bronchitis caused by aspiration of some chemical gases that stimulate the bronchial mucosa. Frequent inhalation of chemical gases caused by cough, chest tightness, suffocation, at first serious, breathing difficulties, three months later, the symptoms have eased, but more sputum, more difficult to cough, chest pain, chest tightness, hernia symptoms still exist. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: non-infectious Complications: chronic bronchitis
Cause
Causes of chemical bronchitis
Coughing, chest tightness, and suffocation caused by inhalation of chemical gas were more serious at first, and difficulty breathing. After three months, the symptoms were relieved, but there were more sputum, and it was more difficult to cough up, chest pain, chest tightness, and hernia still existed.
Prevention
Chemical bronchitis prevention
1. Avoid chemical gas contact.
2. Strengthen self-protection when exposed to irritating gases or harmful substances, and take protective measures such as wearing a mask.
Complication
Chemical bronchitis complications Complications chronic bronchitis
Acute bronchiolitis, chronic cough, acute tracheal-bronchitis, acute tracheobronchitis, chronic bronchitis
Symptom
Symptoms of chemical bronchitis Common symptoms Chest tightness, chest tightness, suffocation, difficulty breathing
(1) Cough: Long-term, repeated, and gradually worsening cough is a prominent manifestation of this disease. The mild ones only occur in the winter and spring seasons, especially before and after getting up in the morning, and there is less cough during the day. Cough reduces or disappears during summer and autumn. In severe cases, the cough in the four seasons, the winter and spring intensified, coughing day and night, especially in the morning and evening.
(2) Cough: Generally, the sputum is white mucus foam, which is more often in the morning, often because it is sticky and not easy to squirt out. Symptoms rapidly increase after infection or cold, increased sputum, increased viscosity, or yellow purulent sputum or wheezing. Occasionally because of a cough and blood in the sputum.
Examine
Examination of chemical bronchitis
Airway allergy test, histamine inhalation test, repeated breath test, effluent lysozyme, challenge test
Because cough is a non-specific symptom of many diseases, it is necessary to ask for detailed medical history, comprehensive physical examination, chest X-ray or CT, airway responsiveness measurement, pulmonary function, electrocardiogram, fiberoptic bronchoscopy and some special cases. Check to rule out other diseases that can cause chronic, intractable cough.
Diagnosis
Diagnosis and diagnosis of chemical bronchitis
The disease is often exposed to irritating chemical gases, and is significantly different from other respiratory diseases in the etiology.
Chronic bronchitis: refers to chronic non-specific inflammation of the trachea, bronchial mucosa and surrounding tissues. It is clinically characterized by a cough, cough, or chronic process accompanied by wheezing and recurrent episodes.
Acute bronchitis: The main symptom is cough, the beginning of the disease, short, dry and cough. After 3 to 4 days, as the exudate increases, it becomes wet and coughs, and the pain is reduced. It is often accompanied by vomiting after coughing.
Allergic bronchitis: A specific type of asthma with chronic cough as the primary or only clinical manifestation. In the early stage of asthma, about 5-6% are persistent cough as the main symptom, mostly at night or in the early morning, often irritating cough, which is often misdiagnosed as bronchitis.
