22 paź 2023 · For instance, a 3-month-old infant's fluid requirements significantly differ from those of a fully grown child aged 8 or older. 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.
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)
Perioperative Fluid Management: The 4 – 2 – 1 rule for maintenance IV fluid therapy (Normal Saline or Ringer’s Lactate): 4 ml/kg/hr for the first 10kg of body mass. 2 mg/kg/hr for the next 10 kg of body mass. 1 mg/kg/hr for body mass beyond 20kg.
A meticulous fluid management is required in paediatric patients because of an extremely limited margin for error. Go to: CRYSTALLOIDS: THE “4/2/1” RULE. Holliday and Segar in 1957 first presented a practical method to prescribe IV fluids based on the estimated metabolic requirements for patients at bed rest. [4]

Fluid Management can be broadly covered in three main parts: (1) resuscitation fluid, (2) maintenance fluid and (3) replacement for the losses.
As stated earlier, calculations are done according to the “4-2-1” rule. This rate can be used solely for parental fluid administration or as a goal for the total hourly fluid intake (also taking into account continuous infusions and/or high-volume medications).
