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.
Maintenance Fluids Calculations. 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.
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.
Holliday-Segar “4-2-1” Rule: No or Not candidate for enteral. “IV Fluid Therapy: First 1-10 kg = 4 mL/kg/hr. Next 11-20 kg = 2 mL/kg/hr. Next > 20 kg = 1 mL/kg/hr. Add together for maintenance rate. Calculation example. BSA method: • BSA (m2) × 1600 mL/m2/day = Daily requirement.
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.
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)
