Rehydration therapy

The treatment of dehydration by administering fluids and salts by mouth (oral rehydration) or by intravenous infusion. The amount of fluid necessary depends on age, weight, and the degree of dehydration. Mild dehydration can usually be treated with oral solutions, which are available as effervescent tablet or powder to be made up at home. In severe dehydration, or if the patient cannot take fluids by mouth because of nausea or vomiting, an intravenous infusion of saline and/or glucose solution may be given in hospital.
