Common causes of yellow water in babies include: infectious diarrhea, indigestion, secondary lactose intolerance, etc. After the baby pulls yellow water, parents should promptly keep the child’s stool samples, sent to the hospital to be laboratory tests, in order to identify the cause of symptomatic treatment. 1, prevention and correction of dehydration: baby pulling yellow water easily lead to dehydration. Be sure to pay attention to the child to reasonably hydrate. As soon as the diarrhea begins, the child should be given enough fluid by mouth and continue to feed the child. The following methods can be used: (1) Oral rehydration salts (ORS): after each diarrhea, give 50~100ml orally to children under 2 years old, 100~200ml to those aged 2~10 years old, and as much as you can drink to those older than 10 years old. It can also be given at 40~60ml/kg, immediately after the start of diarrhea. (2) Rice soup with salt solution: 500ml of rice soup + 1.75g of fine salt or 25g of fried rice flour + 1.75g of fine salt + 500ml of water boiled for 2~3 minutes. The dosage is 20~40ml/kg, served in 4 hours, and given orally anytime afterwards, as much as you can drink. (3) Sugar and salt water: 500ml of boiled water + 10g of cane sugar + 1.75g of fine salt. dosage is the same as rice soup with salt solution. If dehydration occurs in children with diarrhea, such as the appearance of: less tears when crying, dry skin, less urine, etc., electrolytes and water need to be replenished in time to prevent circulatory failure. Most children can be corrected with oral rehydration therapy. Severe dehydration requires intravenous rehydration. 2, drug treatment: (1) pathogenic treatment: non-infectious diarrhea generally does not require antibacterial drugs. However, systemic bacterial infections and diarrhea caused by invasive bacterial infections must be properly given systemic anti-infective treatment. Generally watery stool can be treated without antibiotics, mucus stool and purulent blood stool can be treated with antibiotics, with a full course of treatment, and the medication cannot be stopped without the doctor’s consent. (2) microecological therapy: through the restoration of the human intestinal microecological balance, to achieve the purpose of treatment of intestinal diseases. (3) Adjuvant therapy: intestinal mucosa protective agents (such as sixteen-angle montmorillonite), intestinal dynamics inhibitors, antisecretory drugs, etc. (4) Zinc supplementation therapy: WHO recommends oral zinc supplementation for children with diarrhea while continuing oral rehydration salt therapy, which can enhance immune function and prevent recurrence. 3. Family care: (1) Dietary adjustment: Continue breastfeeding in mild cases, appropriately limit the number of nursing sessions or shorten the duration of each nursing session, and suspend complementary foods; artificially fed children can be fed with equal amounts of rice soup or diluted milk or other milk substitutes, and gradually transition from rice soup, congee, noodles, etc. to a normal diet. For lactose intolerant children, add lactase to the diet or remove lactose from the diet. For allergic diarrhea, switch to hydrolyzed milk powder or amino acid milk powder if protein allergy is considered. During diarrhea, continue to eat and give the baby a normal diet appropriate to its age, and do not “fast” as much as possible, as fasting can lead to prolonged symptoms and loss of nutrition. (2) Keep the abdomen warm: a child’s belly button getting cold can easily lead to increased intestinal peristalsis and aggravate the frequency of diarrhea, so pay attention to reducing the child’s belly button getting cold.
