Standard dehydration treatment includes replenishing the patient with water or sport juices. This process is called re hydration and can be done orally or intravenously.
"Normal" depends on the severity of the dehydration. The vast majority of cases just require oral rehydration with the medical equivalent of Pedialyte. Only in severe cases are IVs used.
In general, depending on the level of dehydration, a hospital emergency room will attach a rehydrating solution intravenously to the afflicted patient.
