To determine whether it is a “gastrointestinal cold”, we must first know what is a “gastrointestinal cold”? “Gastrointestinal flu” usually refers to a cold in which the symptoms of respiratory tract infection such as runny nose and cough are often not obvious, but mainly manifest as gastrointestinal symptoms such as poor appetite, vomiting and diarrhea. But objectively speaking, “gastrointestinal cold” is not a particularly rigorous diagnosis, and there is no such diagnosis in general pediatric books. In foreign countries, “gastrointestinal flu” is the same concept as gastroenteritis, which is a disease unrelated to flu or cold. Therefore, different doctors may have different opinions on the diagnosis of “gastrointestinal flu”, mainly because there are different opinions on the definition of “gastrointestinal flu”. Therefore, it is not necessary for parents to get hung up on the fact that one doctor diagnosed your child with gastroenteritis and another doctor diagnosed a “gastrointestinal” cold. Even if the diagnoses are different, the doctors’ treatment principles are more or less the same: symptomatic treatment for vomiting, diarrhea, and poor appetite. If a child has poor appetite, vomiting, diarrhea, fever and other symptoms, whether they are complications of respiratory tract infection or primary symptoms of gastrointestinal tract infection, there are many similarities in the diagnosis and treatment process: Clear diagnosis Whenever there are obvious gastrointestinal symptoms such as vomiting and diarrhea, fecal examination should be considered. Stool examination includes routine stool, occult blood, rotavirus test or stool culture. Routine stool tests can initially screen for bacterial enteritis and dysentery, while rotavirus tests can determine if rotavirus is responsible for fall diarrhea, and stool culture is required for initial consideration of bacterial diarrhea. If the diagnosis is enteritis and dysentery, antibiotic treatment should be given. If the stool is not abnormal or positive for rotavirus, symptomatic treatment should be required. Symptomatic treatment Anti-emetic and anti-dehydration: When a child has vomiting with fever, relieving the vomiting and ensuring the intake of water and electrolytes is of primary importance. You can take antiemetic medicine to stop vomiting (do not drink water at the same time when taking antiemetic medicine to avoid spitting out all the water and medicine), and start drinking oral rehydration salts (not plain water) 20-30 minutes after taking antiemetic medicine. The amount must be small each time, only 5-10 ml can be drunk every 5-10 minutes, so that water and electrolytes can be taken in and vomiting can be reduced. Most of the children can make up for the loss of body fluids by taking oral rehydration components without water and electrolyte disorders. However, if the child cannot take in water because of vomiting or vomits after drinking, intravenous fluids should be considered. Pay attention to the child’s urine volume is an important indicator of dehydration. If the urine volume is significantly reduced, dehydration should be considered, and fluid intake or intravenous rehydration should be increased at this time.
