The benefits of oral rehydration in the hospital setting are the elimination
of the risks associated with intravenous fluid therapy and a considerable
reduction in the quantity of such fluids used. This bar graph shows the
dramatic reduction in the use of intravenous fluids in a hospital in Jamaica
after oral therapy was introduced: of the total number of children treated for
gastroenteritis, the number receiving intravenous fluids declined from 55% to
4%. This represents a significant saving in costs - both of fluids and
equipment, and of skilled staff time.
