Pediatric viral enteritis is an acute gastrointestinal infection caused by rotavirus. Rotaviral viruses are highly resistant, and the pathogen is mainly transmitted through fecal and oral routes. The virus can multiply in the villous cells of the small intestine, causing damage to the intestinal mucosa and affecting digestion and absorption. The main clinical manifestations are acute fever, vomiting and diarrhea. The course of the disease is mostly short. It is one of the most common causes of diarrhea and can occur in epidemic or pandemic. The resistance of this kind of virus is strong, mainly through the feces, oral route of transmission, the virus can reproduce in the human body in the small intestinal villous cells, resulting in intestinal mucosal damage, affecting digestion and absorption function. Infants and young children with weak gastrointestinal function, especially children from 6 months to 2 years old, infected with rotavirus through food and eating utensils, etc., or contacted with virus-contaminated furniture, doorknobs, or toys, etc., can develop the disease in 1~2 days. It can also cause disease through respiratory infection in the form of aerosols. Clinical Diagnosis It occurs mostly in infants and young children aged 6 to 24 months, and is rare in those over 4 years of age, with a rapid onset of illness. The onset of the disease is rapid. It is often accompanied by fever and symptoms of upper respiratory tract infection, such as fever, cough, red throat, runny nose, etc., mental depression and loss of appetite. There are no obvious symptoms of infection and poisoning, vomiting often occurs in the first 1~2 days of the disease, followed by diarrhea, diarrhea 5~6 times a day, or 10~20 times. Stools are eggdrop soup-like or watery, with a sour smell, because it contains less bile, the color of stools is lighter, so it is also known as “white diarrhea”. It is often accompanied by vomiting and abdominal pain. Due to the massive loss of water and salt from diarrhea, the child may become dehydrated, acidotic, and have electrolyte disorders. There are no specific drugs for viral infections, so rotavirus enteritis relies on symptomatic and supportive treatment. For children with mild to moderate dehydration, oral rehydration is sufficient. Choose the oral rehydration salts (ORS), which are uniformly prescribed by the World Health Organization, and parents only need to dilute it to a certain volume according to the requirements and give it to their children, and the dehydration can generally be corrected. Chinese medicine dialectic treatment of viral enteritis has good efficacy, early can choose to clear heat and dampness, spleen and diarrhea Chinese medicine orally, such as yellow root and rhizome soup or Artemisia annua 20 grams, one dose per day, divided into two decoctions, at the same time with massage, paste, Maundy feet, transdermal drug delivery and other therapies. In addition, children can take oral micro-ecological preparations, such as poly grams, mamma love, etc. to help restore the ecological balance of the normal intestinal flora; can also take Simida or Beechcraft, this kind of drug has the ability to adsorb viruses, bacteria and toxins. Over the years, the Department of Pediatrics of our hospital has accumulated rich clinical experience in the treatment of viral enteritis. In terms of diet, children are given moderate amounts of baking soda and fine salted glucose water. Diet should also be controlled, and those with severe vomiting should be fasted for 6 to 12 hours without water, and then gradually from less to more, from thin to thick. Because fasting and excessive dietary control will affect the growth and development of the child and the repair of the mucosa of the gastrointestinal tract. Numerous studies have shown that feeding during diarrhea still has a significant nutritional effect, because rotavirus infection manifests itself in the intestinal tract as segmental, and the normal intestinal mucosa that has not been involved still has a digestive and absorptive function. At this time, the diet should be adjusted, such as young children should stop feeding greasy, meaty food; children who are adding supplements, should suspend supplements or reduce the number of times and the amount of supplements; small infants can continue to breastfeeding, as far as possible, breastfeeding, should be done in small quantities. Prevention Prevention of pediatric viral enteritis should pay attention to infant feeding hygiene, used bottle nipples with boiling water, adults should wash their hands before feeding children, young children should wash their hands before and after meals, do not eat unclean and spoiled food. If the child has diarrhea, parents should take the child to the hospital in a timely manner to clarify the diagnosis, in order to determine a reasonable treatment plan, can not give the child to use antibiotics, so as not to delay the condition.
