If there are deficits, maintenance should be added to the fluids that replace the deficit. They are not meant to replace deficits (ex, hypovolemia).

Tough dextrose-containing hypotonic fluids are most commonly used for maintenance fluids in pediatrics, they should not be used for boluses or volume beyond calculated hourly maintenance needs. Maintenance fluids are often required to replace expected daily loses.

Fluids needed to replete blood losses and to support blood pressure based on lossesĭue to the large volume of fluids that can be administered perioperatively, it is recommended to use isotonic crystalloids form volume repletion during this setting.Severity of surgical procedure and tissue trauma as it results in redistribution of fluids in the body compartments.While originally derived in pediatric patients, this calculator is applicable to any age. This volume delivered 50% of the first hour of anesthesia and 50% over the next 2 hours Calculates maintenance fluid requirements by weight.Estimation of volume deficit from preoperative fasting (hourly maintenance needs x number of fasting hours).Determination of maintenance fluid needs per the 4/2/1 rule Calculations of fluids for maintenance, replacement, redistribution and resuscitation.Thus, a 22 kg child would be thought to require 62 ml/hr of a hypotonic maintenance fluid (traditionally 5% dextrose in 0.45% sodium chloride).Īccording to Smith’s Anesthesia for Infants and Children: Traditionally, the first step in determining the hourly fluid requirements for a child described by Holliday and Segar and coined as the “4/2/1” rule: For children 20 kg, their needs are calculated by 60 mL + (BW – 20 kg) x 1. Calculate hourly maintenance fluid rates using standard weight-based. approximately 1 mmol/kg/day of potassium, sodium and chloride and. Perioperative fluid replacement for children and infants is a complex and somewhat controversial topic. Standardize care of pediatric patients who require maintenance IV fluids in the. Daily maintenance fluid requirements (as per NICE guidelines): 25-30 ml/kg/day of water and.
