Health reminder: the weather is changeable in summer, and colds occur frequently, which has become one of the most common diseases in children. According to medical observation, a child in a year often repeated cold as many as several times, especially infants and preschool children are prone to cold.
Wrong idea 1: a heavy nasal sound is a cold?
In early childhood, especially under one year old, we often hear snoring in the nose, like secretions shuttling with the breath. In fact, it is nasal excrement, and of course it is also a manifestation of sputum (respiratory secretions). And most mothers will worry about whether the baby has a cold, in fact, most of them are worried about it. Because the main reason for the above phenomenon is that too much nasal secretions slowly dry and stick, especially when there is no change in fever and activity, there is no need to worry. As long as we form good habits and clean nasal secretions every day, we will not have the above situation.
As for what is the real rhinitis? The answer is when the doctor found that there is inflammation in the nasal cavity, that is, redness and swelling, which causes the secretion of nasal mucosa to increase, then the diagnosis can be made.
Wrong idea 2: antibiotics for cold
Viruses or bacteria can cause colds. Cold caused by virus belongs to viral cold, and cold caused by bacteria belongs to bacterial cold. Antibiotics are only useful for bacterial colds.
In fact, many colds are viral. Strictly speaking, there is no effective medicine for viral cold, just symptomatic treatment, without the use of antibiotics. We may all have this experience. After a cold, we habitually buy some cold medicine in the drugstore and add some antibiotics to use. In fact, antibiotics are useless at this time. They are waste and abuse.
Wrong idea 3: do you have to pat your back for expectoration if there is phlegm sound?
The so-called respiratory system includes the nasal cavity, throat, trachea and bronchus, as well as the lungs. Sputum can be produced in any of the above places. Most of them are caused by infection, such as viral infection. When you hear the breath sound of a child and feel phlegm, you should first judge by yourself or ask a doctor to help you understand the position of the sputum. The position of the sputum can be in the upper part of the throat, or in the lower part, that is, the trachea or lung. If the former is the former, it is not necessary to pat the sputum, but to carefully remove the nasal cavity or throat secretions. Of course, if there is sputum sound in the trachea, regular sputum tapping is required.
Wrong idea 4: injection of gamma globulin to prevent cold
Children often catch a cold, so parents are very anxious, heard that this is the reason for low resistance, gamma globulin can play a role in preventing cold, but injected for a period of time, but did not see any effect. Gamma globulin is a biological preparation extracted from plasma. With the current technology, there is still a risk of contamination, which is not 100% safe. Moreover, it only plays a role in the deficiency of specific immune function, which shows that its ability to improve immune function is very limited, let alone prevent cold.
Some of the reasons for children's poor tolerance to antibiotics, such as repeated use of antibiotics, will cause the child's resistance to cold, such as repeated use of antibiotics, the key is to find out the reason why the child's cold resistance is too low; If it is not the above reasons, we should consider disease factors, such as allergic asthma, allergic rhinitis, children also love frequent colds, which needs to be cured first.
Wrong idea 5: have cough to take cough medicine?
For the human body, cough is a kind of physiological reflex. When the respiratory tract inhales foreign bodies or infiltrates and inflames, the information will be uploaded to the cough center in the medulla oblongata of the brain, which will cause intense reflex movement. The purpose is to eliminate the foreign body in the trachea. Therefore, when coughing, the air will be discharged from the deep throat at a violent speed, and the foreign body will be ejected at the same time.
From the above point of view, cough is a self-protection mechanism, which is beneficial to the human body. In addition to distinguishing the difference between expectorant cough and expectorant cough (the former should increase water intake and consider whether to use expectorant drugs), in addition, we should also consider whether dry cough causes discomfort in life. If we can't fall asleep, have a stool cough or vomit, we should consider using appropriate antitussive drugs. This kind of drug has anaesthetic sex and non anaesthetic sex two kinds, therefore must consult doctor carefully, can trust medication.
Wrong idea 6: children can take adult's medicine after 3 years old
Most parents now know that babies need to use special drugs. And when the children are older, some parents think that the drugs are safe for adults, and children can also use them. Just reduce the dose. However, due to the physiological differences between children and adults, adult safe drugs may not be safe for children, sometimes even dangerous. For example, tetracycline drugs are currently eliminated by Pediatrics due to their strong toxic and side effects; gentamicin can cause nerve hearing loss, and children under 6 years old are prohibited; quinolones antibiotics can cause joint lesions and hinder cartilage development, affecting children's height development, so it is not suitable for minors under 18 years old.
Another example is cold pass, adults eat nothing, children may have hematuria after taking, the consequences are serious. Experts remind: before medication, we must read the instructions clearly. The pediatrician should decide what kind of medicine the child uses and how much dose it should be decided by the pediatrician instead of taking it for granted by parents themselves, so as to avoid mistakes.
Wrong idea 7: take expectorant medicine need to eat until there is no phlegm?
When the human body is fighting against virus or bacteria invading the respiratory tract, it will produce secretions due to inflammatory reaction, plus exfoliated epithelium and dead pathogens, resulting in sputum. After a few days of infection, various immune cells are responsible for clearing sputum.
Therefore, when there is phlegm, the first thing to do is to take more liquid and soften the sputum; as for phlegm resolving drugs, only when doctors feel that the sputum is sticky and has a lot of viscosity, it should be used in the first few days of the acute phase, not always until there is no phlegm. Mothers should believe that there should be a scavenger in the baby's body. As long as the environmental factors (including water intake, temperature and humidity) are properly adjusted, the body will recover naturally.
The above common misconceptions can be seen every day in the outpatient clinic. Here, we call on all parents who love their babies not to follow the same line, pass on the wrong or even turn black and white upside down. On the contrary, it will make the baby's illness difficult to relieve. You should think about reasonable actions before dealing with your baby. Look at the pediatrician's Encyclopedia, or call your pediatrician. You can do the best and correct health care for your baby with respiratory diseases.
