What is the formula for maintenance fluid rate?
What is the formula for maintenance fluid rate?
Formulas Used: For 0 – 10 kg = weight (kg) x 100 mL/kg/day. For 10-20 kg = 1000 mL + [weight (kg) x 50 ml/kg/day] For > 20 kg = 1500 mL + [weight (kg) x 20 ml/kg/day]
How do you calculate fluid deficit maintenance?
Deficit (mL) = weight (kg) x % dehydration x 10
- For children with ≤5% dehydration, replace deficit in the first 24 hours.
- For children with >5% dehydration, replace deficit more slowly.
How do you calculate fluid requirements?
Fluid needs are often calculated on a per body weight basis, with an adult baseline of 30-35mL/Kg. 3 This recommendation is adjusted up or down based on specific medical conditions, such as heart failure, liver or kidney disease, as well as if a patient is taking certain medications.
What is the hourly fluid maintenance mL HR requirement for a female patient that weighs 60 kg?
4-2-1 Maintenance Rate Quick Lookup Table
| Weight | Weight | Rate |
|---|---|---|
| 33 lbs | 15 kg | 50 mL/hr |
| 44 lbs | 20 kg | 60 mL/hr |
| 55 lbs | 25 kg | 65 mL/hr |
| 66 lbs | 30 kg | 70 mL/hr |
How do you calculate IV maintenance fluids?
Maintenance Fluid Rate is calculated based on weight.
- 4 mL / kg / hour for the first 10kg of body mass.
- 2 mL / kg / hour for the second 10kg of body mass (11kg – 20kg)
- 1 mL / kg / hour for any kilogram of body mass above 20kg (> 20kg)
How do you calculate child maintenance?
In the below example, each child will be allocated 25% percent of the total expense shared by the three members of the household. 25% for Child 1 + 25% for Child 2 + 50% for Adult = 100% of household expense.
How do you calculate pediatric maintenance IV fluids?
- 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 fluid maintenance for a dog?
The volume of rehydration fluids required is determined by reassessing hydration parameters after resuscitation, using the following formula: % dehydration × body wt (kg) × total body water (0.6). This volume is commonly administered throughout 4–12 hours with standard isotonic, balanced electrolyte replacement fluids.
How do you calculate IV fluid?
The formula for calculating the IV flow rate (drip rate) is total volume (in mL) divided by time (in min), multiplied by the drop factor (in gtts/mL), which equals the IV flow rate in gtts/min.
How do you calculate IV fluid intake?
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 is fluid maintenance?
Maintenance fluid is based on replacing fluid/electrolytes due to insensible losses (principally water losses from the skin and lungs) and urinary losses of water and electrolytes. Gastrointestinal losses are considered negligible in the absence of a pathologic process, such as diarrhea.
What is a reasonable child maintenance?
A child is entitled to reasonable maintenance for the essential needs for himself or herself, for example, clothing, housing, food, education and medical care. There is an obligation on each parent to provide the essential needs of the child. This legal duty is called “the duty to maintain” or “the duty to support”.
What is the formula for maintenance fluid?
Calculate the hourly maintenance fluid rate for a child who weighs 25kg. (100mL x 10kg) + (50mL x 10kg) + (20mL x 5kg) / 24hrs. (1000mL) + (500mL) + (100mL) = 1600mL / 24hrs = 66.7ml/hr. Using this formula the hourly fluid maintenance for this child is 67mL/hr.
How to calculate maintenance fluids?
Maintenance Fluid Calculation for Children. 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 to calculate maintenance fluids in PEDs?
The rule for calculating maintenance fluids for a 24 hours period, is the 100/50/20 rule. IV administration of 100ml/kg for the first 10kg is given. Then 50ml/kg for the next 10kg and then 20ml/kg for every kg over 20. Once this has been figured, you divide the amount by 24 to get the hourly IV fluid flow rate.
What is the 421 rule for IV fluids?
The 421 rule is used to calcuate the hourly infusion rate for maintenance fluids (generally just for pediatrics). 4 cc/hr for kg 1-10.
