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.
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.

The Maintenance Fluids Calculator calculates maintenance fluid requirements by weight.
This calculator determines the fluid requirement that needs to be corrected in pediatric patients based on weight (because total body water relies on weight). There are two calculation methods used, the Holliday-Segar nomogram and the 4 – 2 – 1 rule.
