How is pediatric fluid deficit calculated?

How is pediatric fluid deficit calculated?

The first step is to calculate the fluid deficit. This is determined by multiplying the percentage dehydration times the patient’s weight (e.g. 10% dehydration in a 10 kg child: 10% of 10 Kg = 1 kg = 1 liter). Subtract any boluses from this volume (e.g. 1 liter – 400 ml of boluses = 600 ml).

How do you calculate pediatric fluid requirements?

1. For infants 3.5 to 10 kg the daily fluid requirement is 100 mL/kg.
2. For children 11-20 kg the daily fluid requirement is 1000 mL + 50 mL/kg for every kg over 10.
3. 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 is Hypernatremia calculated?

TREATMENT: Method A: The first step in treating hypernatremia is estimating the water deficit. Total body water (TBW) = 60% (0.6) of body weight for men, 50% (0.5) of body weight for women, 45% (0.45) of body weight for elderly.

How do you calculate fluid replacement?

Formulas Used:

1. For 0 – 10 kg = weight (kg) x 100 mL/kg/day.
2. For 10-20 kg = 1000 mL + [weight (kg) x 50 ml/kg/day]
3. For > 20 kg = 1500 mL + [weight (kg) x 20 ml/kg/day]

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.

How do you calculate free water deficit?

Free Water Deficit (FWD) = TBW x (serum [Na] -140) / 140; TBW = wt (kg) x 0.6 (male) or 0.5 (female). If elderly use, 0.5 (male) and 0.45 (female) Note: The FWD does is not constant but will change moving forward. It doesn’t include of ongoing free water losses.

What is the formula for free water deficit in hypernatremia?

Free Water Deficit in Hypernatremia Formula on Mdcalc.com is: Formula for Free Water Deficit in Hypernatremia Free Water Deficit (FWD) = TBW x (serum [Na] -140) / 140; TBW = wt (kg) x 0.6 (male) or 0.5 (female).

How to calculate the amount of free water required to balance?

The formulas used to calculate the amount of free water required to balance the deficit are: TBW is total body water = correction factor x weight in kg Taking as example the case of an adult male, weighing 97kg and a measured Na+ of 117mEq/L.

What is the water deficit formula for an adult male?

Taking as example the case of an adult male, weighing 97kg and a measured Na+ of 117mEq/L. The water deficit formula is: FWD = -9.56 L ■ One of the most common causes of this condition is due to dehydration through loss from the gastrointenstinal tract, skin or urine.
