Which patients is suitable for bronchoalveolar lavage?

Which patients is suitable for bronchoalveolar lavage? Definition: Bronchoalveolar lavage (BAL) is a new technology developed on the basis of fiberoptic bronchoscopy. It is a method of injecting physiological saline into the bronchoalveolar with a bronchoscope and then sucking it out, collecting the effective liquid on the surface of the alveolar, and then checking its cellular components and soluble substances. Clinically used to diagnose a variety of lung diseases: such as alveolitis, pulmonary fibrosis, asbestosis, lung cancer, pneumocysticercosis, alveolar proteinosis, etc. Clinical diagnosis, differential diagnosis, and research on the etiology and pathogenesis of lung diseases. To evaluate the efficacy and prognosis. Indications for bronchoalveolar lavage: 1. Diagnosis, differential diagnosis and prognostic evaluation of interstitial lung diseases. 2. Etiological examination of lung infection. 3. Cytological diagnosis of lung cancer and other lung tumors. 4. Diagnosis of other lung diseases, such as alveolar proteinosis, pulmonary hemosiderinosis, diffuse alveolar hemorrhage, asbestos lung, etc. 5. Remove sputum retained in the airways of patients with intractable lung infections. 6. Treatment of persistent bronchial asthma, excessive sputum during bronchiectasis, chronic bronchitis and interstitial pneumonia. “Bronchoalveolar lavage” contraindications: 1. Heart failure, severe arrhythmia, recent myocardial infarction, severe pulmonary insufficiency and acute respiratory failure, etc.; 2. Recently there is massive hemoptysis, exclude patients with diffuse alveolar hemorrhage; 3. Active pulmonary tuberculosis without treatment; 4. Patients with obvious electrolyte abnormalities. Precautions for bronchoalveolar lavage: 1. During operation, avoid trauma and cause the patient to cough, otherwise it may cause obvious contamination of mucus and blood. 2. During the entire lavage process, the bronchoscope must always be kept in a proper position to prevent overflow of lavage fluid and contamination of airway secretions. 3. The negative pressure suction should be less than 80mmHg, otherwise the distal airway may collapse and the recovery will be affected. 4. During the lavage process and within 2 hours after lavage, all patients should be routinely observed vital signs and pulse oxygen saturation, and oxygen therapy should be given to hypoxic patients. Summary: This operation is mainly used to diagnose the differential diagnosis of various lung diseases, study the etiology and pathogenesis of lung diseases, evaluate the efficacy and prognosis, and has little therapeutic effect. The above knowledge is partly taken from the Internet.

Can genital warts flush the vagina?

  Some women in sexual life do not want to use condoms, often use lavage to prevent condyloma acuminatum, is this practice scientific?   In fact, lavage of the vagina is not good. Regular lavage will cause the natural healthy secretions and bacteria in the vagina to be cleared, destroying the acidic environment in the vagina, and susceptible to infection. At the same time, the bacteria may be washed into the uterine cavity, causing ascending infections, such as appendicitis and pelvic inflammatory disease. And frequent lavage will cause vaginal dryness and itching, and it is easy to cause damage to the vaginal mucosa during intercourse. This makes it very easy for HPV and other viruses to enter the human body through the injury gap of the vaginal mucosa, causing condyloma acuminatum infection. Rinse gently with warm water and do not use hot water to clean it at any time, because hot water will cause local irritation and damage, and it is not suitable to use cold water. This is not only because cleaning the cold water will feel uncomfortable, but it is not easy to secrete locally. Washing things; female sex organs have a natural defense function. This natural defense mechanism mainly refers to the large amount of lactobacilli that reside in the female vagina. They can make the glycogen in the vaginal epithelial cells into lactic acid, so as to keep the vagina. The acidic environment prevents other pathogenic bacteria from growing. For whatever reason, the acidic environment in the vagina is destroyed, and various pathogenic bacteria will take advantage of it. At this time, various gynecological infections are difficult to avoid.
