Hourly fluid requirement = (4 mL/kg/hour × 10 kg) + (2 mL/kg/hour × 5 kg) = 40 mL/hour + 10 mL/hour = 50 mL/hour - check. The 4-2-1 rule is a convenient and easy-to-remember method for estimating maintenance fluid rates in pediatric patients. However, it is important to note that this rule is a simplified approach and may not account for ...
26 lis 2023 · One of the primary objectives of maintenance parenteral fluid therapy is to provide water to meet physiologic losses (insensible loss + urine loss). ... 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 ...
For hourly maintenance rate – 4-2-1 Rule. Using 4, 2, 1 formula (Holliday – Segar’s Formula) More accurate for ml/hr calculation. Weight= 6kg (this falls within first 10kg) Formula: 4 ml/kg/hr for 1st 10kg of body weight. Thus, = 4ml × 6 = 24ml/hr.
Malcolm Holliday, MD, (d. 2014) was a pediatric nephrologist and physiologist. Dr. Holliday’s original work studying inherited tubular disorders and congenital renal defects eventually led him to become professor of pediatrics and chief of the Division of Pediatric Nephrology at University of California San Francisco, a position he held for over two and a half decades of his 60 year career.
19 lip 2024 · For 24 hours — Holliday-Segar method. first 10 kg × 100 ml/kg/24h + next 4 kg × 50 ml/kg/24h = 1200 ml/24h. For one hour — 4-2-1 rule. first 10 kg × 4 ml/kg/24h + next 4 kg × 2 ml/kg/24h = 48 ml/24h. The answer: the amount of daily pediatric maintenance fluids is 1200 ml, and the hourly demand is 48 ml.
28 lip 2021 · The Holliday-Segar nomogram approximates daily fluid loss, and therefore the daily fluid requirements, as follows: 100 ml/kg for the 1st 10 kg of wt. 50 ml/kg for the 2nd 10 kg of wt. 20 ml/kg for the remaining wt. Even though it is correct to think about fluid requirements on a 24-hour basis, the delivery pumps used in hospitals are designed ...
5 lip 2023 · Calculating IV Fluid Rate/Volume. Caution should be exercised in using "maintenance" IV fluids at rates above the calculated maintenance; fluid replacement should be calculated separately to account for ongoing losses. 4-2-1 rule (100-50-20 rule) 4 mL/kg/hr (100 mL/kg/day) for the first 10kg PLUS. 2 mL/kg/hr (50 mL/kg/day) for the second 10kg PLUS.
