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.
Calculates maintenance fluid requirements by weight. INSTRUCTIONS. While originally derived in pediatric patients, this calculator is applicable to any age. Consider using ideal body weight in obese patients. If not calculating based on ideal body weight, use clinical judgment for dosing.
This IV maintenance calculator determines the pediatric fluid requirement based on the Holliday-Segar Nomogram and the 4-2-1 rule.
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.
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. [13] The formula outlined below illustrates its application, where fluid maintenance rates are calculated based on the following criteria:
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.
6 dni temu · 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.
