    Children 0-10 kg: 100 ml/kg per day
    Children 11-20 kg: 1000 ml + (50 ml/kg for every kg over 10 kg) per day
    Children > 20 kg: 1500 ml + (20-25 ml/kg for every kg over 20 kg) per day
    Adults: 2 litres per day
     for patients unable to drink sufficiently. After 48 hours, it is essential to provide nutrition to the patient orally or by nasogastric tube and to gradually reduce IV fluids.

     

     
    This protocol should not be used for surgical or burns patients, those with renal, cardiac disease or diabetic ketoacidosis.

    Fluid to be administered

    The fluid of choice in children is Ringer lactate-Glucose 5% (RL-G5%). Use a premixed solution if available. If not, add 50 ml of G50% to 500 ml of RL or 100 ml of G50% to 1000 ml of RL. If RL is not available, use 0.9% sodium chloride instead.

     

    For ease of prescription and administration, the daily volumes and rates in drops per minute have been rounded off.
