There is no quick relief for infant vomiting, which may be caused by improper feeding, upper respiratory tract infection, gastrointestinal infection, etc. It is mainly treated with general therapy and medication (such as cefadroxil, etc.). 1. Improper feeding: Because babies are small and their stomachs are horizontal, if they are overfed or if they are allowed to lie down immediately after feeding, it will easily lead to vomiting, and they should be properly burped after feeding the baby. 2. Upper respiratory tract infection: If the baby’s upper respiratory tract infection is more serious, it may also cause vomiting. For viral infections, there is no specific antiviral drug, you should let the baby drink more warm water and pay attention to keep warm. For bacterial infections, the infant should be allowed to take some antibacterial drugs, such as amoxicillin clavulanate potassium, cefadroxil and other drugs. 3. Gastrointestinal infections: most commonly seen in rotavirus infection, attention should be paid to hydration, to avoid electrolyte disorders in infants, if necessary, intravenous fluid therapy. If the baby repeatedly vomits, should promptly go to the hospital to identify the cause of targeted treatment. The above drugs should be used under the guidance of a doctor.
