Bronchiectasis, as the name implies, is an abnormal, irreversible dilation and deformation of the bronchial lumen caused by a variety of factors. Bronchiectasis can occur at any age, but is more common in children and young adults. Most of them are secondary to acute or chronic respiratory infections and bronchial obstruction, and most of them have a history of childhood measles, whooping cough or bronchopneumonia. Now, the change of seasons, weather changes, serious pollution, etc., do not trigger the nerves of patients with bronchiectasis, the slightest carelessness, the symptoms began to aggravate. These “original sins” have led to a series of clinical symptoms in patients with bronchiectasis, which seriously affect their health and quality of life. The course of bronchiectasis is mostly progressive, with the airway gradually enlarging, scarring and distorting in severe liquids. The bronchial walls can cause severe respiratory failure and death due to edema, inflammation and neovascularization. The main causes are bronchio-pulmonary tissue infection and bronchial obstruction. Bronchiectasis may also be caused by congenital developmental disorders and genetic factors, but it is less common. The etiology of bronchiectasis is unknown in about 30% of patients and may be related to genetic, immune imbalance or anatomical defects of the organism. All of the above diseases impair host airway clearance mechanisms and defenses, making them less capable of clearing secretions and prone to infection and inflammation. Repeated bacterial infections can thicken the mucous formation filled with inflammatory mediators and pathogenic bacteria. Inability to properly discharge sputum Flowing water does not rot, and the household pivot is not worm-eaten. The objective “original sin” of bronchiectasis patients, both internal and external, naturally makes patients forced to “suffer”. Simply put, patients with bronchial dilatation cannot expel sputum normally, and the sputum that slips in and out of the body invites bacterial reproduction, which leads to repeated bronchial infections, followed by concomitant vasodilation and even vascular rupture leading to hemoptysis, which in turn can lead to death by asphyxia. This progressive cycle makes the patient’s condition worsen with each attack. How to face this progression? We are not helpless to do anything. The important goal of treatment of bronchiectasis is to control the symptoms and slow down the progression of the disease. Bronchiectasis is usually secondary to other diseases, so the primary disease should be treated promptly and the combined sinusitis, etc. should be treated thoroughly. In the 12th National Conference on Respiratory Infections, Professor Huo Jieming made a deep appeal to patients with bronchiectasis to pay attention to the treatment of the stable phase of the disease. The unique structure of bronchial dilatation makes it difficult to expel sputum, so being able to expel sputum smoothly during the stabilization period is necessary to reduce bacterial reproduction and control infection. The unique principle of negative pressure pulsation is utilized in the Supreme Clear Lung Instrument to pump air outward regularly like a pulse, which can well help patients expel mucus sputum, and the efficacy of which has spread by word of mouth among patients and benefited many people. 2.Acute attack period The main measure is to actively control the infection. According to the condition, antibacterial drugs are selected with reference to the results of bacterial culture and drug sensitivity test, and antibiotics can be used empirically before the sputum culture results or when the sputum culture is negative: amoxicillin or cephalosporin can be chosen orally in mild cases; oral quinolones can be chosen in the presence of Pseudomonas aeruginosa infection; intravenous combination drugs are often needed in severe cases: metronidazole or tinidazole is added for treatment if there is anaerobic bacterial mixed infection. In patients with recurrent acute lower respiratory tract infections or hemoptysis, limited lesions, not easily controlled by drug therapy, and in good general condition, lung segment or lobectomy may be performed depending on the extent of the lesion. Prevention is particularly important in the prevention of bronchiectasis, which can effectively slow down the progression of the disease. To prevent the disease before it happens, we need to actively respond. 1, prevention of cold and flu, cold often induces the occurrence of bronchial dilatation infection. So the cold should increase and decrease the clothes in time, pay attention to keep warm and avoid the cold. 2.If you repeatedly cough up pus sputum, you should insist on using the lung clearer to discharge the mucous sputum smoothly to prevent choking. Or perform postural drainage and back patting every day. Exhausting accumulated sputum can effectively reduce secondary infection and toxic symptoms. For patients with a large amount of sputum, it is important to prevent choking due to excessive gushing of sputum. 3. When there is hemoptysis, make sure to hemoptysis the blood naturally, never hold it in, because the blood will soon clot in the trachea and block the airway causing asphyxia. 4, eat a high protein, high calorie, high vitamin and nutritious diet, such as eggs, fish, meat and fresh vegetables, fruits and so on. Do not drink strong tea, coffee and other stimulating drinks. 5, remission period can do breathing exercises and appropriate whole body exercise. Adhere to participate in appropriate physical exercise, such as walking, playing Tai Chi, etc., is conducive to the prevention of attacks. 6, avoid exertion and mood swings, keep a happy mood, avoid exposure to smoke and irritating gases. Bronchial dilatation varies in severity, early start of active prevention and positive response can significantly improve the prognosis of patients and their quality of life. No matter rain or shine, winter or spring, their smiles are still bright.
