4 2 1 Rule Calculating Pediatric Maintenance Fluids 4 2

Calculating Pediatric Maintenance Fluids 4 2 1 Rule 4 2 1 rule. the 4 2 1 rule is a simplified method for estimating hourly maintenance fluid requirements in pediatric patients. the 4 2 1 rule provides an alternative approach to the holliday segar formula, which calculates daily fluid requirements. instead, it estimates the hourly fluid rate based on the patient's weight. the rule is as follows:. One of the primary objectives of maintenance parenteral fluid therapy is to provide water to meet physiologic losses (insensible loss urine loss). in a study published in 1957, in the journal pediatrics, malcolm holliday and william segar developed a simple scheme which could be easily remembered to calculate the maintenance water needs in hospitalized patients.

Maintainance Replacement Fluid Therapy Pediatrics Ag The maintenance fluids calculator (mivf calculator) uses the holliday segar method and the 4 2 1 rule to determine the daily and hourly need for fluids in children.as well as finding out these pediatric maintenance fluids, you can also work out the proper size of the pediatric fluid bolus to be given in times of need. While originally derived in pediatric patients, this calculator is applicable to any age. consider using ideal body weight in obese patients. if not calculating based on ideal body weight, use clinical judgment for dosing. a 1 liter bolus may be appropriate for most patients, such as overweight adolescents and adults. when to use. why use. weight. Calculating iv fluid rate volume. caution should be exercised in using "maintenance" iv fluids at rates above the calculated maintenance; fluid replacement should be calculated separately to account for ongoing losses. 4 2 1 rule (100 50 20 rule) 4 ml kg hr (100 ml kg day) for the first 10kg plus. 2 ml kg hr (50 ml kg day) for the second 10kg plus. The maintenance fluid calculator uses the holliday segar method and the 4 2 1 rule to determine the daily and hourly need for fluids in both adults and pediatric patients. in addition to determining the appropriate pediatric maintenance fluids, you can also calculate the correct size of the pediatric fluid bolus to administer in emergencies.
