Great attention to respiratory medicine

Date:2020-03-03

Spring is the peak of all kinds of respiratory diseases. Once respiratory diseases attack, they are often accompanied by infection, fever, cough, asthma and other symptoms. At this time, drug treatment is essential. Professor Chen Guozhong of the respiratory department of the people's Hospital of Wuhan University reminded that in the process of treating respiratory diseases, special attention should be paid to the use of the following drugs.


Antibiotics: insist on application for 3-5 days


Respiratory diseases are mainly infection, and antibiotics are often needed. There are many pathogenic microorganisms that cause respiratory diseases. For different pathogenic microorganisms, the choice of antibiotics is different. In addition, we should pay attention to its usage, dosage, course of treatment and side effects in the application of antibiotics. Therefore, antibiotics must be used under the guidance of doctors. In particular, do not change antibiotics frequently. It takes 3-5 days for an antibiotic to work. Do not expect the symptoms to disappear as soon as the drug is used. An antibiotic should be used for 3-5 days to judge whether it is effective or not, and to decide whether to change antibiotics.


Antitussive drugs: try not to use or use less


Coughing is a protective reflex that removes foreign bodies or secretions (sputum) from the respiratory tract. Therefore, if cough does not affect daily life, sleep, work, try not to use or use less antitussive drugs, the fundamental problem of cough relief is to eliminate the inflammation of the respiratory tract.


Expectorant drugs: suitable for elderly patients


Another important treatment for respiratory diseases is sputum drainage. If the sputum drainage is not good, any antibiotic application is ineffective. Therefore, it is often difficult to control the respiratory system infection in some elderly patients with senile or delirious mind. The root cause is that they can't or can't expectorate. For respiratory infectious diseases, if sputum is not easy to cough up, it is necessary to use expectorant drugs. For critical patients, it can even use fiberbronchoscope to attract sputum.


Antiasthmatic drugs: no more than 1G / day


Antiasthmatic drugs include theophylline, β 2 agonists, anticholinergic drugs and hormone guidance. For theophylline drugs, we should pay attention not to overdose, not more than 1G per day; β 2 agonists, anticholinergic drugs and some hormone drugs are inhalers, we should read the instructions more, understand the method of inhalation, and generally consult a doctor after taking the drugs. For the application of hormone drugs, we should not be afraid. The treatment amount of inhaled hormone is very small, and it is a local treatment, with little side effects on the body. But we should pay attention to mouthwash. The long-term concentration of hormone in the mouth can cause ulcers. The general time of systemic hormone treatment is not long, and it has little impact on the body.


Antipyretic drugs: easy to cover up the illness and use as little as possible


Although antipyretic drugs can alleviate symptoms, they often can not solve the fundamental problems. The harm lies in: first, some patients eat less and sweat a lot after using antipyretic drugs, which can cause collapse, even coma and shock. Especially for the elderly and children, if it is not necessary to use it, it is necessary to drink more water or replenish fluids intravenously. Second, because of the use of antipyretic drugs, the body temperature has subsided, but whether it is caused by the effect of antibiotic treatment is not easy to judge. Therefore, the use of antipyretics is not conducive to judge the efficacy of antibiotics. In clinic, try to use physical cooling, use less moderate antipyretics when necessary, if not strong antipyretics, make up fluid, and monitor the changes of blood pressure and mind.
