50 ml/kg/24-hours = 2 ml/kg/hr for the 2nd 10 kg.

100 ml/kg/24-hours = 4 ml/kg/hr for the 1st 10 kg.The 24-hour number is often divided into approximate hourly rates for convenience, leading to the '4-2-1' formula. The Holliday-Segar nomogram approximates daily fluid loss, and therefore the daily fluid requirements, as follows:Įven though it is correct to think about fluid requirements on a 24-hour basis, the delivery pumps used in hospitals are designed to be programmed for an hourly infusion rate. Holliday and Segar determined how many calories a patient burns as a factor of weight. The diagram below is taken from their original publication 'The maintenance need for water in parenteral fluid therapy', Pediatrics 1957. So for a 70-kg male, the infusion rate would be 40 + 40 + 40 120 cc/hr. Caloric expenditure, and therefore the water requirement, for the hospitalized patient can be estimated from the nomogram shown below. Pegasus52082 said: The 421 rule is used to calcuate the hourly infusion rate for maintenance fluids (generally just for pediatrics).This means that for every 100 kcal burned, the patient utilizes 100 ml of fluid. Total daily water requirement to replace insensible and urinary water loss in the hospitalized patient is approximately 100 ml/100kcal/day.

Water loss (and therefore water requirement) is a function of caloric expenditure.

Holliday and Segar collated information from a number of studies, including their own, and concluded the following:

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. The commonly used method for approximating water loss (and therefore the water requirement) is based off of the Holliday-Segar nomogram. The resting energy expenditure in healthy children is vastly different from those with an acute disease and/or illness or after surgery. Blood draw should not exceed 21.It is clinically useful to begin fluid therapy by estimating normal maintenance requirements using the estimated caloric expenditure method.How much blood can be drawn on a newborn weighing 5kg?.1-3 year olds 70mL/kg total blood volume Should not exceed 1-5% of total blood volume in one day While originally derived in pediatric patients, this calculator is applicable to any age. List the formula needed to calculate the daily fluid requirements for a child weighing 11-20 Kg: (Pg 4) 1000 mL + 50 mL/Kg for each Kg above 10 Kg. Calculates maintenance fluid requirements by weight. The safe volume of PRBCs to transfuse for this patient is 150-300mL maintenance fluid requirements are calculated using the 4,2,1 rule (4ml/kg/hr for the first 10kg, 2ml/kg/hr for the second 10kg, and 1ml/kg/hr after that, with. List the formula needed to calculate the daily fluid requirements for a child up to 10 Kg: (Pg 4) 100mL/Kg/ 24 hour.What is the safe Packed Red Blood Cell volume for a patient weighing 15kg?.Patient 6kg: 6kg X 100mL= 600mL/day Patient 13kg: 1000mL + 50(3)= 1150mL/day This calculator determines the fluid requirement that needs to be corrected in pediatric patients based on weight (because total body water relies on weight).

What should the maintenance fluids be for a patient weighing 6kg, 13kg, 45kg, and 100kg?.Pt weighing >20kg, daily fluid requirement is 1500mL + 20mL/kg for every kg over 20.Pt weighing 11-20kg, daily fluid requirement is 1000mL + 50mL/kg for every kg over 10.Pt weighing 3.5-10kg, daily fluid requirement is 100mL/kg.What is the BSA of a 34kg patient who is 122cm?.How much does a patient who weighs 75lbs weigh in kg?.I developed this quick cheat sheet of common calculations to help keep our pediatric patients safe!

#MAINTENANCE FLUID CALCULATOR PEDS HOW TO#

Knowing how to do these calculations is imperative because kids are extremely sensitive to being given too much fluid or having too much taken out. We get infants all the way up to 26 year olds! Because of this, the majority of pediatric nursing is based off of the patient’s weight in kilograms. One main difference between adult and pediatric nursing is that children come in all different shapes and sizes.
