Cold, also known as upper respiratory tract infection, is a common pediatric disease. After 6 months of age, babies are born with exhausted immune antibodies from their mothers, and their own immune function is not established, so they cannot produce enough immune antibodies yet. Since there is no specific medicine for cold and flu, it is necessary to wait until the child produces a certain amount of antibodies and immunologically active factors on his own that are sufficient to deal with the virus, which usually takes 1-2 weeks. Medications for colds and flu are mainly for symptom relief, so antibiotics are usually not needed. Especially in viral infections, antibiotics are not only ineffective, but their abuse can cause dysbiosis in the organism’s flora. Antibiotics should be considered only when bacterial infection or secondary bacterial infection is confirmed. So what should you pay attention to when your child has a cold? 1, careful observation: pay attention to have to check whether there is a rash on the child’s body, and whether there is swelling and pain in the armpit and the root of the thigh. If you find that your child is slow to recover from a cold, or the symptoms gradually worsen, coughing, shortness of breath, unstable temperature or high fever after the fever has subsided, you should think about whether the condition is aggravated or there are comorbidities. 6 months-3 years old children with high fever from a cold should also be alert to the occurrence of high fever convulsions. Therefore, during a cold, pay attention to the following symptoms: Otitis media ~ high fever that does not subside, ear pain, irritability of the toddler, scratching the ears. Sinusitis ~ runny nose that does not improve for more than ten days, or a thick yellow-green nose accompanied by coughing, severe nasal congestion, and headache. Pneumonia ~ High fever that doesn’t go away and cough that gets worse, shortness of breath, fatigue, loss of appetite. Meningitis ~ severe headache, vomiting, convulsions, unconsciousness, and bulging fontanelle in small infants with unclosed fontanelles. 2, adequate rest: the younger the child is, the more rest he or she needs to wait for the symptoms to disappear before resuming free activities. Sometimes children are not always willing to sleep even if they are sick, which indicates that they still have the strength to move around, so mothers need not worry about this. During the child’s rest period, keep the room quiet, fresh air, no smoking, the temperature is appropriate, appropriate to increase indoor humidity. 3, timely cooling: If the body temperature exceeds 38.5 ℃ or more, we must immediately take physical cooling or drug cooling. Drug cooling to comply with medical advice, physical cooling can be used to take a warm bath, pillow ice bags and cold towels on the forehead. Do not wear too much clothing, too thick, too thick, too tightly wrapped, not conducive to heat dissipation. At the same time, give the child to drink more water to help sweat, to help the body temperature drop. 4. Take your medication on time: just because your child’s fever has gone down, it doesn’t mean that your child will immediately get better, and may cause other symptoms such as runny nose or cough. At this time, the child’s resistance is still weak, and if there is a cough, treatment should continue. Use some medicine to relieve cold symptoms. 5, pay attention to diet: children with a cold and fever often have a poor appetite, do not force the child to eat. You should arrange the time to eat when the body temperature is close to normal, when the child feels slightly comfortable and can eat some food, according to the child’s appetite and digestive ability, respectively, to give liquid or thin porridge, noodles and other food. Children with diarrhea and other gastrointestinal symptoms can fast for about 4 hours to let the gastrointestinal tract rest, then give liquid first, and then gradually resume a normal diet, or a light and easily digestible diet is appropriate.
