It is not normal for babies to appear drowsy with diarrhea. Diarrhea can be a precursor symptom of upper respiratory tract infection caused by some enteroviruses, or it can be an intestinal symptom caused by an enterovirus. Babies are often in a poorer mental state after being infected by the virus and appear drowsy. Parents should pay attention to the following points when their baby is drowsy: (1) Observe the baby’s body temperature: If the body temperature is higher than 38.5 degrees Celsius, you need to use antipyretic drugs under the guidance of a doctor. (2) Prevention and correction of dehydration: Diarrhea causes a large amount of water and electrolyte loss in the body. Therefore, as soon as diarrhea begins, the child should be given adequate oral fluids and continue to feed the child, especially infant breastfeeding, to prevent dehydration. The following methods can be used: (1) Oral rehydration salts (ORS): after each diarrhea, give 50~100ml orally under 2 years old, 100~200ml for 2~10 years old, and as much as you can drink for 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.
