What is the Holliday Segar equation?
The Holliday-Segar equation remains the standard method for calculating maintenance fluid requirements. Accounting for deficits when determining the fluid. Maintenance fluid therapy as defined by Holliday and The formula assumes normal renal function . Holliday/Segar formula of ml/kg body weight (BW).
What is the Holliday-Segar method?
The Holliday-Segar method is usually preferred due to its ease of calculation; however, the other methods are employed in some instances. The Holliday-Segar method may be simplified by estimating the fluid requirements in rate required per hour.
What is the holiday Segar method of weight loss?
The Holiday-Segar method can only be applied to patients above 2 weeks of age. 2. This method does not take into consideration caloric expenditures above average, or take into account on-going fluid losses; a more rigorous method would be the caloric method .
What is the Holliday Segar method of calculating maintenance fluid?
Please review our privacy policy. Holliday segar method is a widely acceptable method of calculating maintenance fluid, especially in children. The patient became hyponatremic after receiving ethacrynic acid, and it was unclear whether the patient received the subsequent order for a sodium chloride infusion.

How is holiday Segar calculated?
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.
How do you calculate daily fluid maintenance for pediatrics?
For infants 3.5 to 10 kg the daily fluid requirement is 100 mL/kg. For children 11-20 kg the daily fluid requirement is 1000 mL + 50 mL/kg for every kg over 10. For children >20 kg the daily fluid requirement is 1500 mL + 20 mL/kg for every kg over 20, up to a maximum of 2400 mL daily.
How do you calculate IV fluids in pediatrics?
Therefore, to calculate the total 24-hour fluid requirements we would use the following two formulae: Fluid deficit (mL) = 10% dehydration x weight (kg) x 10. Total fluid requirement (mL) = maintenance fluids (mL) + fluid deficit (mL)
How do you calculate percentage of dehydration?
After clinical signs have been observed, the degree (%) of dehydration should be determined. This is calculated by dividing the difference between the pre-illness and illness weights by the pre-illness weight, then multiplying by 100 (Table 5). For example, a 10-kg patient who has lost 1 kg is 10% dehydrated.
What is the 4 2 1 rule for maintenance fluids?
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.
How do you calculate 24-hour fluid maintenance?
The 24-hour number is often divided into approximate hourly rates for convenience, leading to the "4-2-1" formula.100 ml/kg/24-hours = 4 ml/kg/hr for the 1st 10 kg.50 ml/kg/24-hours = 2 ml/kg/hr for the 2nd 10 kg.20 ml/kg/24-hours = 1 ml/kg/hr for the remainder.
What are the 3 main types of IV fluids?
There are three types of IV fluids:Isotonic.Hypotonic.Hypertonic.
What is the formula of fluid calculation?
The formula to calculate how many hours will it take for the IV to complete before it runs out is: Time (hours) = Volume (mL) Drip Rate (mL/hour) . The volume of the fluid is 1 000 mL and the IV pump set at 62 mL/hour.
What is a normal IV fluid rate?
Normal daily fluid and electrolyte requirements: 25–30 ml/kg/d water 1 mmol/kg/day sodium, potassium, chloride 50–100 g/day glucose (e.g. glucose 5% contains 5 g/100ml). Stop IV fluids when no longer needed. Nasogastric fluids or enteral feeding are preferable when maintenance needs are more than 3 days.
How do you measure hydration status?
Changes in body weight, urinary indices, blood osmolality and hormone concentrations, heart rate, blood pressure, skinfold thickness and perception of thirst are among the indices that are used to assess hydration status. The most widely used are urinary indices, namely urine osmolality, USG and urine colour.
What is degree of dehydration?
In general, dehydration is defined as follows: Mild: No hemodynamic changes (about 5% body weight in infants and 3% in adolescents) Moderate: Tachycardia (about 10% body weight in infants and 5 to 6% in adolescents)
How do you calculate a 5% fluid deficit?
Deficit (mL) = weight (kg) x % dehydration x 10For children with ≤5% dehydration, replace deficit in the first 24 hours.For children with >5% dehydration, replace deficit more slowly.More items...
The Holliday-Segar Method for calculating Maintenance Fluids and ...
The Holliday-Segar Method In the Holliday-Segar Method, fluid and electrolyte requirements are empirically based on the caloric needs of the average hospital patient.This caloric expenditure is approximated based on body weight using the following table:
IV Maintenance Fluids Calculator
This calculator allows determination of maintenance fluids for pediatric patients, however, past, current and prospective hydration statuses need to be taken in consideration and given the consequences of under dosing (dehydration, renal insufficiency) and over dosing (edema, fluid overload) the calculations may need to be adjusted.
Maintenance Fluid Calculations - Medscape
The maintenance fluid calculator was derived in 1957 by Holliday and Segar for the pediatric population but has persisted in use for both adults and pediatric patients to date.

How old do you have to be to use Holiday Segar?
1. The Holiday-Segar method can only be applied to patients above 2 weeks of age. 2. This method does not take into consideration caloric expenditures above average, or take into account on-going fluid losses; a more rigorous method would be the caloric method . Net Scut Home.
When is potassium added to a fluid?
Potassium is usually added after the patient's first void in an amount that will yield the above maintenance level.
Variables and formula
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.
About maintenance fluid therapy
When the body cannot preserve the normal volume of fluids and the electrolyte balance, fluid replenishment becomes necessary to ensure homeostasis and to make sure cardiac output is optimized.
What is the Holliday-Segar formula?
The Holliday-Segar formula is a formula to help approximate water and caloric loss (and therefore the water requirements) using a patient's body weight. Primarily aimed at pediatric patients, the Holliday-Segar formula is the most commonly used estimate of daily caloric requirements.
Can Holliday serum be used for fever?
While generalizable to most cohorts, the Holliday-Segar formula may inadequately estimate caloric requirements in patients affected by fever , hypothermia, or increased activity states (ie, hyperthyroidism or status epilepticus). The formula can also only be applied to patients above 2 weeks of age.
