How many days does the pneumonia vaccine take effect?
Pneumonia is a common infectious disease of the respiratory system. For the elderly who are frail, infants and young children who repeatedly suffer from pulmonary infections, and adults with immune deficiencies, it is an option to get vaccinated against pneumonia. Generally, antibodies are produced in the body 2 to 3 weeks after vaccination, which may protect against most types of pneumococcal bacteria. Different pneumonia vaccines vary in the duration the antibodies last in the body, with most lasting about one year. For bivalent and trivalent pneumonia vaccines, the immune protection can last about five years.
What medicine is used for bronchiectasis?
Bronchiectasis is particularly common clinically. The choice of medication for bronchiectasis needs to be determined based on the specific conditions of the patient. Generally, the aggravation of bronchiectasis is caused by recurrent infections, so controlling infections is fundamental in treatment. As for the application of antibiotics, the principle we follow is to select medications based on the different bacterial spectrums in different regions, with the most scientific method being the use of sensitive antibiotics identified through sputum bacterial culture and drug susceptibility tests. Additionally, we also use expectorants like ambroxol and bromhexine. If there is concurrent respiratory distress or a decline in lung function, inhalants such as budesonide-formoterol powder may also be used.
Symptoms of pneumonia in infants
Pneumonia is a particularly common infectious disease of the respiratory system. In infants and young children with pneumonia, the main clinical symptoms include fever, crying, vomiting, and so forth. Since infants cannot express their discomfort, it is difficult to make a diagnosis. However, when a patient presents with fever, we first need to consider the possibility of a lung infection. We can determine whether there is an infection of the lungs through listening to the chest, routine blood tests, imaging examinations, etc., and then treat the pneumonia with effective anti-inflammatory therapy.
Symptoms of pneumonia in children
Pneumonia is a particularly common infectious disease of the respiratory system, and infants and young children are especially susceptible to pneumonia because their immune systems are much weaker than those of healthy adults. When infants and young children develop pneumonia, their symptoms differ from adults; they often exhibit only fever, crying, nausea, vomiting, etc. The symptoms of coughing and phlegm are relatively less obvious, making the diagnosis of pneumonia in infants and young children somewhat more difficult. If a patient exhibits fever, auscultation and routine blood tests can be used to preliminarily determine the presence of an infection. If pneumonia is suspected, further comprehensive imaging examinations can be conducted to confirm the diagnosis.
Can people with bronchiectasis eat lamb?
Patients with bronchiectasis can eat mutton, as in traditional Chinese medicine, mutton is considered a warming and tonifying food. It generally benefits conditions like cold-induced cough, chronic bronchitis, and deficiency-cold asthma. Patients with bronchiectasis, who often suffer from repeated lung infections and have lower immune function, are generally weaker, so consuming an appropriate amount of mutton can be beneficial. However, it should not be consumed in excess as mutton can cause heatiness or indigestion, which are particularly detrimental for individuals with bronchiectasis.
How is bronchiectasis cured?
Bronchiectasis is a type of chronic respiratory disease characterized primarily by recurrent coughing and sputum production. Once diagnosed with bronchiectasis, it is incurable. Prevention is crucial, and the main reason for recurrent episodes of bronchiectasis is infection. Therefore, preventing infection is paramount, including annual vaccinations against influenza and pneumonia to prevent infections. Additionally, it is important to avoid excessive fatigue and extreme emotions, as these can trigger episodes of bronchiectasis. Bronchiectasis is caused by chronic suppurative inflammation and fibrosis of the bronchi and surrounding lung tissue, leading to the destruction of the muscular and elastic tissues in the bronchial walls, resulting in deformation and permanent dilation of the bronchi.
What to do if bronchiectasis causes chest tightness?
Patients with bronchiectasis often experience chest tightness, usually due to infections and a decline in lung function, so an initial effective pulmonary imaging examination is necessary. If an infection is present, actively controlling the infection can alleviate symptoms. Furthermore, lung function tests should be further refined. If there is concomitant ventilatory dysfunction and reduced lung function, inhaling bronchodilators or corticosteroids can improve symptoms. Since bronchiectasis is incurable once diagnosed, effective prevention is also very important. In summary, the causes of chest tightness in bronchiectasis are infections and decreased lung function.
Can bronchiectasis be treated with nebulization?
Patients with bronchiectasis can undergo nebulized inhalation, and nebulized inhalation has a very good therapeutic effect for the treatment of bronchiectasis. Commonly used nebulized medications include budesonide suspension and terbutaline nebulizer solution, among others. These medications work to dilate the bronchi and relieve airway spasms. For patients with excessive phlegm, these treatments can promote expectoration. They are also very effective for patients with bronchiectasis-caused breathing difficulties. Furthermore, there is now literature proving that inhaling budesonide suspension has a good anti-inflammatory effect on lower respiratory tract infections and helps in the absorption of inflammation.
Newborn pneumonia symptoms
Neonatal pneumonia is primarily aspiration pneumonia, which differs from the symptoms of pneumonia in adults. Neonates do not exhibit signs such as coughing or expectoration. Instead, they often show symptoms of anorexia, vomiting, gasping, and fever. During physical examination, wet rales can be heard through auscultation. Once pneumonia is diagnosed, the first step is to clear the newborn's respiratory tract to maintain its patency. At the same time, selecting appropriate antimicrobial drugs to actively control the infection can lead to recovery. (Please use medication under the guidance of a doctor.)
How to cure bronchiectasis?
Bronchiectasis is caused by chronic suppurative inflammation and fibrosis of the bronchi and the surrounding lung tissue, damaging the muscles and elastic tissues of the bronchial walls, leading to deformation and permanent dilation of the bronchi. Bronchiectasis is chronic in formation, thus once diagnosed, it is incurable. Prevention is very important. The main cause of recurrent episodes of bronchiectasis is infection, so preventing infections is crucial. It is advised to consume a high-quality protein diet, participate in appropriate physical activities, and get annual vaccinations for influenza and pneumonia to prevent infections.
