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.
26 lis 2023 · 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.
The Maintenance Fluids Calculator calculates maintenance fluid requirements by weight.
This online maintenance fluid calculator uses both the Holliday-Segar Formula and the 4-2-1 Rule to determine maintenance fluid requirements. This maintenance fluid calculations: Estimates the volume required per kg to maintain hydration in healthy children; Accounts for insensible losses (from breathing, through the skin, and in stool)
19 lip 2024 · 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.
Maintenance Fluid Rate is calculated based on weight. 4 mL / kg / hour for the first 10kg of body mass; 2 mL / kg / hour for the second 10kg of body mass (11kg - 20kg) 1 mL / kg / hour for any...
28 lip 2021 · The commonly used method for approximating water loss (and therefore the water requirement) is based off of the Holliday-Segar nomogram. 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.
