These are the principles of oral rehydration therapy: (1) there is a need to
correct the existing water and electrolyte deficits - i.e., rehydration, ,and
ORS is ideal for this purpose; (2) the continuing losses need to be replaced -
i.e., maintenance, which can also be done using ORS; while (3) the normal
daily fluid needs are met through continued breast feeding or the
administration of plain water or other liquids.
