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.
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)
The Maintenance Fluids Calculator calculates maintenance fluid requirements by weight.
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.
22 paź 2023 · In many cases, a simple calculation called the 4-2-1 rule can determine the hourly rate of fluid maintenance required for a child based on their body weight. The formula outlined below illustrates its application, where fluid maintenance rates are calculated based on the following criteria:
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.
