Spring is the season of recovery, the earth is full of vitality, but the temperature is still cold, parents care for their babies a little inattention, it is easy to cause diarrhea baby. Recently, a one-year-old baby girl in Shenzhen was sent to the hospital for treatment because of vomiting and diarrhea, but unexpectedly, the next day had a sudden convulsion and eventually died. According to local media reports, the baby girl’s critical condition was likely due to an intestinal infection causing an associated encephalopathy, which included rotavirus. The pediatric clinics of Jiangsu Provincial People’s Hospital Maternal and Child Branch and Jiangsu Provincial Maternal and Child Health Hospital have also recently seen many small babies with gastrointestinal discomfort, vomiting and diarrhea, and fever due to rotavirus infection. What are the dangers of rotavirus infection? How should parents take good care of their babies after infection and what preventive measures are available for rotavirus? Hurry up to follow the editor to learn together! According to Dr. Chen Hui, deputy chief of the Department of Pediatrics of Jiangsu Provincial People’s Hospital, Jiangsu Provincial Maternal and Child Health Hospital, among the various viruses and bacteria that cause diarrhea in babies, intestinal rotavirus is the most common pathogen that causes the disease in babies aged 6-24 months, but is rare in those aged 4 years or older. Although diarrhea caused by rotavirus is called “autumn diarrhea”, the incidence is not low in winter and spring, especially in the southern part of China, which is often the peak season. Chen Hui, director of the rotavirus infection, clinical manifestations of acute fever, vomiting at the beginning of the disease, followed by osmotic diarrhea, severe dehydration symptoms. Because rotavirus enteritis infection is not only through fecal-oral transmission, but also through the aerosol form of respiratory infection and cause the initial symptoms similar to the common cold, easy to be ignored. When infants and children are infected with these viruses, there is an incubation period of about 1-3 days before the onset of symptoms, and clinical manifestations usually begin with vomiting and fever, followed by profuse diarrhea. The number of stools increases, mostly within 10 times a day, but may reach dozens of times a day, in large amounts, yellow or light yellow, watery or egg-flake soup-like, without fishy odor. Rotavirus infection can also invade several organs, such as the heart, causing myocardial involvement; invade the nervous system, causing convulsions. How to take care of a baby with rotavirus infection? According to Dr. Chen Xiaoqing, Deputy Chief Physician of the Department of Pediatrics, the course of rotavirus-induced diarrhea in children is usually 3-8 days, and parents should follow medical advice to treat the diarrhea. Because of the number of diarrhea, babies are prone to dehydration symptoms. At this time, parents should pay attention to give babies appropriate warm water, preferably oral rehydration salt solution, and it is recommended to supplement a certain amount of liquid after each loose stool until the diarrhea stops to maintain electrolyte and acid-base balance in babies’ bodies; babies should avoid overfeeding when they have diarrhea to reduce the burden on the intestines, and give children nutritious, vitamin-rich and easily digestible food. In case of violent vomiting, fasting should be increased gradually when the baby is 4-6 hours old; babies with diarrhea should pay more attention to buttock cleaning. If your baby has repeated vomiting, diarrhea that does not improve for more than 2 days, decreased urine output, poor spirits and fever that does not go away, parents should take your baby to the hospital in time. Since the disease is somewhat contagious, mothers and fathers should pay attention to the following points for prevention: 1, it is best to breastfeed. Since breast milk is rich in immunoglobulins, it helps to enhance the immunity of infants and children’s gastrointestinal tract; for breast-fed babies, mothers should scrub their breasts clean before feeding. For artificially fed infants, special attention should be paid to the sterilization of milk utensils, which are now dispensed and eaten. 2. Pay attention to dietary hygiene to prevent diseases from entering through the mouth. The mother should wash her hands after each diaper change, after dispensing milk, before feeding the grandmother and before feeding the baby. 3. Feed reasonably and establish good eating habits. Do not add supplementary food during diarrhea. After the diarrhea stops, add gradually, only one kind each time, add in small amounts, do not add several complementary foods at the same time. 4, keep good indoor air circulation, can reduce the chance of virus infection. Take your baby less to medical places and public places where sick children are concentrated, and try not to contact babies with diarrhea. Dr. Chen Xiaoqing, deputy chief of pediatrics, reminded parents that the diagnosis of rotavirus mainly relies on clinical manifestations and stool examination. In order not to affect the accuracy of the test results, please be sure to properly retain your baby’s stool specimen. In the clinic, we often encounter parents who bring in diapers, cloth diapers, and diapers with their child’s stool, which can affect the accuracy of the test results due to the absorption of water and some lesion components in the stool. The correct specimen collection is to use a dry, clean, non-absorbent, disposable stool box (provided by window 2 of the hospital’s second floor testing center), and the amount of dilute stool is about 5 ml, and the amount of formed stool is 5 grams (fingertip size) for testing; if there is no disposable stool box around, parents can use clean, dry, non-absorbent utensils, such as washed and dried glass bottles, disposable plastic bags, etc., and then seal them, taking care not to Do not mix with urine; after the stool is collected, the examination should be completed within 1 hour and not more than 2 hours, otherwise the test results will be affected by PH and digestive enzymes.
