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 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.
The Maintenance Fluids Calculator calculates maintenance fluid requirements by weight.
A 32 kg child needs 72 ml of maintenance fluids per hour using the 4-2-1 rule, totaling 1728 ml per day. Use Maintenance fluid calculator to calculate daily maintenance fluids and fluid flow rate (mL/hr) at once.
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.
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...
Variables and formula. 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.
