50 ml/kg/24-hours = 2 ml/kg/hr for the 2nd 10 kg The maintenance fluid calculator was derived in 1957 by Holliday and Segar for the pediatric population but has persisted in use for both adults and pediatric patients to date.100 ml/kg/24-hours = 4 ml/kg/hr for the 1st 10 kg For a child who weighs 42 pounds, the correct IV drip rate for fluid maintenance is how many mL/hr First, find the childs weight: 42/2.2 19.09.Whether administered either during anesthesia or to a sick patient, fluid therapy often begins with the maintenance rate, which is the amount of. The 24-hour number is often divided into approximate hourly rates for convenience, leading to the "4-2-1" formula. Recommended maintenance fluid rates (mL/kg/hr)49. 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. Calculate the fluid volume needed for rehydration.
Therefore, you multiply 10 kg by 60 ml/kg/day and determine that the patient needs 600 ml/day of IV fluids to meet maintenance requirements. The normal maintenance fluid rate for small animal patients is 50-60 ml/kg/day. The diagram below is taken from their original publication "The maintenance need for water in parenteral fluid therapy", Pediatrics 1957. Calculate the patient’s maintenance fluid rate. Caloric expenditure, and therefore the water requirement, for the hospitalized patient can be estimated from the nomogram shown below.This means that for every 100 kcal burned, the patient utilizes 100 ml of fluid. Examples: Calculate the maintenance fluid requirements for a child whose. Total daily water requirement to replace insensible and urinary water loss in the hospitalized patient is approximately 100 ml/100kcal/day. Maintenance Fluids 1500- 2000 mL/ M2/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. Recommended Maintenance Fluid Rates (mL/kg/hr)49 Cats Dogs Formula:803 body weight (kg)0.75 Formula: 132 3 body weight (kg)0. 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. Required milk = Baby’s age equivalence × Baby’s weight \text 60 ml of milk per feeding.It is clinically useful to begin fluid therapy by estimating normal maintenance requirements using the estimated caloric expenditure method. Since we are using both age and weight, the formula to evaluate a baby's milk intake is: The first one finds the total amount of milk needed by the baby during the day and the second one computes the amount of milk per serving. The baby's milk intake calculator performs two different calculations.
