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 · To calculate the volume of fluid to be administered according to the 4-2-1 rule, which provides hourly fluid requirements, you can use the following guidelines: For the first 10 kilograms (3-10 kg) — 4 ml/kg/h. For the next 10 kilograms (11-20 kg) — 2 ml/kg/h. For weights above 20 kilograms — 1 ml/kg/h.
The Maintenance Fluids Calculator calculates maintenance fluid requirements by weight.
5 lip 2023 · Recommendations. Maintenance IV fluids are appropriate for euvolemic patients who cannot take adequate enteral fluids. Calculate hourly maintenance fluid rates using standard weight-based formula (4-2-1 rule)
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
The continuous administration of IV fluids inpatient pathway outlines the algorithm for selecting the initial IV fluid composition and rate when treating a hospitalized patient who requires IV fluids due to dehydration and/or the inability to take 100% of their fluid needs enterally.
