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 IV maintenance fluid calculator is a tool addressed to clinicians that need to determine the fluid requirement for correction of total water loss in pediatric patients (children and infants). It is based on two calculation methods: the Holliday-Segar Nomogram and the 4-2-1 rule and only requires the patient’s weight.
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.
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.
17 wrz 2019 · This rule helps to easily calculate the maintenance fluid needs in hospitalized patients. Maintenance fluid can be defined as the amount of fluid required to compensate for ongoing fluid losses (insensible and sensible), thus maintaining steady state in the body.
Total hourly rate: 40 + 20 + 12 = 72 mL/hr. 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.
25 wrz 2023 · Instead of the 4-2-1 rule, healthy children presenting with marginal to moderate hypovolemia (e.g., fasting for surgery) should be administered 20-40 mL/kg of isotonic fluids during the surgery and postanesthesia care unit.
