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 she was not expected to have a sudden convulsion the next day and eventually died. Among the various types of viruses and bacteria that cause diarrhea in babies, intestinal rotavirus is the most common pathogen, which can easily cause the disease in babies aged 6-24 months, and is rare in those aged 4 years or older. Although the 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. The clinical manifestations of rotavirus infection are acute fever, vomiting at the beginning of the illness, followed by osmotic diarrhea, and severe dehydration. Because rotavirus enteritis is not only fecal-oral, but also aerosolized through the respiratory tract, the initial symptoms of rotavirus enteritis are similar to those of the common cold and can be easily overlooked. 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? The duration of rotavirus-induced diarrhea in children is usually 3-8 days, and parents should follow medical advice to treat the diarrhea. Babies are prone to dehydration symptoms because of the number of diarrhea. 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 the baby’s body; 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. If there is severe vomiting, you need to fast for 4-6 hours to gradually increase feeding; babies with diarrhea should pay more attention to buttock cleaning, mothers can wash their babies’ small butts with warm water and then apply some refreshing oil-based buttock cream to prevent “red farts”; mothers should wash their hands regularly before and after caring for their babies with diarrhea to prevent cross infection. At the same time, the baby’s clothes and toys should be thoroughly cleaned and disinfected; if the baby has repeated vomiting, diarrhea does not improve for more than 2 days, the urine volume decreases significantly, the spirit is not good, the fever does not go down and other symptoms, parents should promptly take the baby to the hospital for consultation. 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 the infant’s gastrointestinal tract; for breast-fed babies, the mother should scrub her 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 illness 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 often to medical and public places where sick children are concentrated, and try not to contact babies with diarrhea. The diagnosis of rotavirus mainly relies on clinical manifestations and stool examination. In order not to affect the accuracy of the test results, please make sure to keep the stool specimen of your baby correctly. 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 dry, clean, non-absorbent disposable stool box dilute stool retention amount of about 5 ml, formed stool retention of 5 grams (finger size) sent 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. after the retention of sealed, pay attention not to mix with urine; stool retention, should be completed within 1 After the stool is collected, the examination should be completed within 1 hour, and try not to exceed 2 hours, otherwise the test results will be affected by PH and digestive enzymes, etc.
