Routine maintenance fluid therapy is required if the current oral intake is not sufficient to remain hydrated.įor example, if the patient is ‘nil by mouth’ for any significant period, full maintenance fluids will be required.Īlternatively, if the patient can obtain some of their intake orally, but is not completely meeting their fluid requirements, they may be given a percentage of full maintenance fluids based on their intake. In these cases, it is necessary to determine the indication for fluids, type of fluid and volumes/infusion rate required.īroadly there are three indications for IV fluids in infants and children: routine maintenance, replacement and resuscitation. However, there are certain situations where the oral route is contraindicated or impractical. oral rehydration solution) via the oral or nasogastric route should be used.
