Fluid intake per hour for children

Children often suffer from symptoms of cold and fever. In severe cases, injections are required for treatment. However, for children who are too young, attention should be paid to their physical condition and the amount of fluid to be administered should be determined based on the specific age of the child. Because the child's body tolerance is limited, it is necessary to pay attention to the appropriate amount of fluid injected when the child is sick. How much fluid should be injected per hour for children?

The calculation of the amount of fluid infusion is mainly determined by the degree of dehydration in the child's body. If it is mild dehydration, it can be supplemented by oral administration. If oral administration is not possible, intravenous fluid infusion is used, about 90~120 ml/kg·day. If it is poisonous dehydration, it is 120~150 ml/kg·day, and severe dehydration is 150~180 ml/kg·day. You can calculate it yourself based on the child's weight. For example, a 20 kg child, if only relying on intravenous infusion, should be supplemented with 2000 ml per day for mild dehydration, 2800 ml per day for severe dehydration, and 3200 ml per day for severe dehydration.

Fluid intake includes the liquid content in diet and water, while fluid output mainly comes from urination, defecation, evaporation from the respiratory tract, and evaporation from the body surface.

Generally, babies need 100-110 ml of liquid for every kilogram of body weight to meet their body needs. When your baby is two years old, he should weigh about 12 kilograms and generally need 1200 ml of liquid.

Moderate dehydration is generally calculated as 100ml/kg, which is 8kg×100=800ml. For isotonic dehydration, it is 400ml of 0.9% saline and 400ml of 5% sugar water (10% sugar water is high in sugar and is generally not used, but it can be used at 400). This is the daily amount. First replenish 400ml, and then observe. In general, replenish as much as the child is lacking, until the child urinates. If there is no urine, it proves that there is still dehydration. Supplementing with 5% soda water generally depends on the binding capacity of nitrogen dioxide. Moderate dehydration is generally calculated at 1-2ml/kg. To be safe, you can replenish your child with 8ml and add a drop to 100ml of sugar water. Generally speaking, as long as the child has urine, there is no need to supplement with soda water, because the kidneys can regulate the acid-base balance through urination.
