How do you calculate maintenance fluid for a child?

  1. For infants 3.5 to 10 kg the daily fluid requirement is 100 mL/kg.
  2. For children 11-20 kg the daily fluid requirement is 1000 mL + 50 mL/kg for every kg over 10.
  3. For children >20 kg the daily fluid requirement is 1500 mL + 20 mL/kg for every kg over 20, up to a maximum of 2400 mL daily.

What is normal fluid maintenance rate?

Normal Maintenance Requirements This formula is based on the energy expenditure of healthy children, with 1 mL of fluid provided for each kcal expended, or 1500 mL/m2 per day.

How do you calculate fluid allowance?

Formulas Used:

  1. For 0 – 10 kg = weight (kg) x 100 mL/kg/day.
  2. For 10-20 kg = 1000 mL + [weight (kg) x 50 ml/kg/day]
  3. For > 20 kg = 1500 mL + [weight (kg) x 20 ml/kg/day]

How do you calculate daily fluid maintenance?

Maintenance Fluid Rate is calculated based on weight.

  1. 4 mL / kg / hour for the first 10kg of body mass.
  2. 2 mL / kg / hour for the second 10kg of body mass (11kg – 20kg)
  3. 1 mL / kg / hour for any kilogram of body mass above 20kg (> 20kg)

What is the maintenance fluid rate for a 22 kg child?

For infants 3.5 to 10 kg the daily fluid requirement is 100 mL/kg. For children 11-20 kg the daily fluid requirement is 1000 mL + 50 mL/kg for every kg over 10. For children >20 kg the daily fluid requirement is 1500 mL + 20 mL/kg for every kg over 20, up to a maximum of 2400 mL daily.

How do you calculate IV fluid rate for pediatrics?

What is maintenance fluid for pediatrics?

Maintenance fluids consist of water, glucose, sodium, and potassium. The glucose prevents starvation ketoacidosis and decreases the likelihood of hypoglycemia. Water, sodium and potassium protect the patient from dehydration and electrolyte disorders.

How much maintenance fluid would a patient receive if they are 18 kg?

What is the 4 2 1 rule for maintenance fluids?

In anesthetic practice, this formula has been further simplified, with the hourly requirement referred to as the “4-2-1 rule” (4 mL/kg/hr for the first 10 kg of weight, 2 mL/kg/hr for the next 10 kg, and 1 mL/kg/hr for each kilogram thereafter.

Why maintenance fluid is important?

Urine production constitutes the majority of fluid loss in healthy patients. Maintenance fluid therapy is indicated for patients that are not eating or drinking, but do not have volume depletion, hypotension, or ongoing losses. Replacement fluids (e.g., LRS) are intended to replace lost body fluids and electrolytes.
