Every winter, the high incidence of respiratory diseases winter, babies are more prone to illness compared to adults because all aspects of their functions are not yet well developed. Common respiratory diseases are mainly upper respiratory tract infections, acute tonsillitis, bronchitis, pneumonia, etc. The symptoms are fever, cough, sore throat, etc. Mothers and fathers are very nervous and distressed when they see their babies sick, and in order to let them recover as soon as possible with less pain, they often ask the doctor to give them fluids when they go to the hospital, thinking that fluids are more effective than oral medication. Is this really true? In fact, this is a misconception of parents. In fact, most diseases do not require infusions, and some diseases do not recover faster from infusions than from medication. For example, upper respiratory tract infection, commonly known as the flu, more than 90% is caused by viral infection, manifested as fever, runny nose, cough, sore throat, clinical treatment is generally symptomatic treatment, given oral antipyretics and cough and throat drugs. Since viral infections are self-limiting, babies can recover quickly with proper treatment and adequate rest, and there is no need for infusion therapy at all. At present, the effect of antiviral drugs on the symptoms of viral infections is not very precise. The application of antibiotics to treat viral infections is not only ineffective, but the abuse of antibiotics can also lead to drug resistance in babies and affect the treatment of future diseases. In addition, there are some disadvantages of infusion itself, such as cross-infection among children, which may aggravate the disease. Frequent infusions and the use of antibiotics increase the resistance of bacteria, and the effectiveness of infusions will be reduced. The liver and kidney functions of babies are not yet well developed, and infusions increase the burden on the liver and kidneys. Children are more likely to have infusion reactions than adults, causing damage to various organs. Common infusion reactions such as fever, chills or chills, anaphylaxis, etc. Some infusion reactions are difficult to reverse once they occur. Intravenous infusion can also cause irritation to the baby’s blood vessels, and the baby may feel pain at the infusion site during the infusion process. Of course, there are some cases that still need to be treated with infusion. For example, the baby’s general condition is relatively poor, bad spirit, or severe vomiting unable to eat; diarrhea appears serious dehydration; or serious infection. Therefore, it is advocated that mothers should raise their children’s medication habits from childhood, and it is best not to insist on infusion treatment when medication can be taken orally. Oral medication has the least adverse reactions and is therefore the safest, and can also prevent cross-infection and reduce adverse reactions when infusing babies.
