How do you calculate maintenance fluids for adults?
How do you calculate maintenance fluids for adults?
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)
What is the maintenance fluid formula?
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]
What IV fluids are used for maintenance?
The preferred fluid type for IV maintenance is sodium chloride 0.9% with glucose 5%
- Plasma-Lyte 148 with glucose 5% (contains 5 mmol/L of potassium) – generally stocked in tertiary paediatric centres and intensive care.
- Hartmann’s with glucose 5%
How do you calculate MIVF?
How to use MIVF calculator – practical example
- For 24 hours – Holliday-Segar method. first 10 kg * 100 ml/kg/24h + next 4 kg * 50 ml/kg/24h = 1200 ml/24h.
- For one hour – 4-2-1 rule. first 10 kg * 4 ml/kg/24h + next 4 kg * 2 ml/kg/24h = 48 ml/24h.
How are maintenance fluids peds calculated?
- 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 peds maintenance fluids?
What is maintenance fluid?
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 the best maintenance fluid?
Commonly used fluids
| FLUID TYPE | TONICITY | K + (mmol/L) |
|---|---|---|
| Sodium chloride 0.9% (Normal saline) | Isotonic Used for resuscitation/maintenance | |
| Hartmann’s solution | Isotonic Used for resuscitation/maintenance | 5 |
| Sodium chloride 0.18% / Glucose 4% | Hypotonic Used for maintenance | |
| 5% Dextrose | Hypotonic Used for maintenance |
How do you calculate maintenance fluid for IV fluids?
Example of a IV fluid calculation These are the two methods for calculating pediatric maintenance fluid rates, applied in the case of a child weighing 26 kg. 1) Daily volume formula: (100 mL for each of the first 10 kg) + (50 mL for each kg between 11 and 20) + (20 mL for each additional kg past 20 kg) = 1,000 mL + 500 mL + 120 mL = 1,620 mL.

How do you calculate maintenance fluid per kg h?
4 mL/kg/h for first 10 kg body weight. + 2 mL/kg/h for next 10kg body weight. + 1 mL/kg/h for subsequent body weight. *For overweight/obese patients, calcuate the normal maintenance fluid based on ideal body weight (IBW, see below). Adapted from the WHO, 1997.
How is normal maintenance fluid calculated for overweight/obese patients?
*For overweight/obese patients, calcuate the normal maintenance fluid based on ideal body weight (IBW, see below). Adapted from the WHO, 1997. Ideal Body Weight for overweight or obese adults can be estimated based on the following formula. For adults with IBW >50kg. 1.5 – 2ml/kg can be used for quick calculation of hourly maintenance fluid regime.
