What is Fried’s law?
Fried’s rule is a method of estimating the dose of medication for a child by dividing the child’s age in months by 150 and multiplying the result by the adult dose.
Pediatric dose = child’s age in months.
How do you calculate maintenance fluids?
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 maintenance fluid for pediatrics?
Maintenance fluids are used when a patient is NPO. Maintenance fluids consist of water, glucose, sodium, and potassium. The glucose prevents starvation ketoacidosis and decreases the likelihood of hypoglycemia. Water, sodium and potassium protect the patient from dehydration and electrolyte disorders.
What is Young’s rule formula?
[Age / (Age + 12)] x Recommended Adult Dose = Pediatric Dose Young’s Rule can be applied to quickly approach a situation in which the patient’s weight is unknown.
What is the maintenance IV fluid rate for an 88 lb child?

What is the difference between friends rule and Young’s rule?
Calculate the proper dose for a child when given the adult dose of a drug using the following methods: … Friend’s Rule (Using the Child’s Age in Months) Young’s Rule (Using the Child’s Age in Years)
How do you calculate IV fluid rates?
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 much does a baby need to drink to stay hydrated?
If your baby weighs 6 pounds, he or she needs at least 9 to 12 ounces of fluid each day. If your baby weighs 10 pounds, he or she needs at least 15 to 20 ounces of fluid each day. When babies have a fever, are vomiting, or have diarrhea, they may need 2 to 3 ounces of fluid for every pound of body weight.
How much IV fluid is given for dehydration?
Intravenous fluid administration (20-30 mL/kg of isotonic sodium chloride 0.9% solution over 1-2 h) may also be used until oral rehydration is tolerated.
How do you prepare maintenance fluid?
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 percentage of dehydration?
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. Every 1 kg of weight lost is equivalent to 1 L of fluid loss.
What is weight based dosing?
General. Most drugs in children are dosed according to body weight (mg/kg) or body surface area (BSA) (mg/m2). Care must be taken to properly convert body weight from pounds to kilograms (1 kg= 2.2 lb) before calculating doses based on body weight.
How do you calculate drug dosages?
A basic formula, solving for x, guides us in the setting up of an equation: D/H x Q = x, or Desired dose (amount) = ordered Dose amount/amount on Hand x Quantity.
How do you calculate medication by weight?
Simply multiply the dose by the weight to determine the dose required which may then be placed in other formula. 2mg / kg of a drug is required in a single dose.
Which IV fluid is best for dehydration?
If you are correcting only dehydration (as when giving a bolus in the ER), use 0.9% saline. If you are correcting dehydration and providing maintenance fluids at the same time, add both volumes and use D5 0.45% saline. If you are providing fluid only, may use D5 0.18% saline or D5 0.33% saline.
What is a fluid balance chart?
A fluid balance chart is used to document a patient’s fluid input and output within a 24-hour period. This information is used to inform clinical decisions (such as medication and surgical interventions) from medical staff, nurses and dieticians, who all expect accurate figures in exact measurements (Georgiades 2016).
What are the 3 main types of IV fluids?
Here is a brief description of each:0.9% Normal Saline (NS, 0.9NaCl, or NSS) … Lactated Ringers (LR, Ringers Lactate, or RL) … Dextrose 5% in Water (D5 or D5W, an intravenous sugar solution) … 0.45% Normal Saline (Half Normal Saline, 0.45NaCl, .
Is normal saline a maintenance fluid?
The appropriate volume of normal saline can be combined with the hypotonic saline being used for provision of maintenance fluid requirements so that the final solution is D5 0.45% normal saline. NEVER use excessive volumes of hypotonic saline as a maintenance fluid.
How do you calculate pediatric 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.More items…
What is the formula for Clark’s rule?
Clark’s rule equation is defined as the weight of the patient in pounds divided by the average standard weight of one hundred fifty pounds multiplied by the adult dose of a drug equals the pediatric medication dose, as is demonstrated below: (Weight* divided by 150 lbs.)
What is Dilling formula?
An age-based formula for calculating the paediatric dose of a drug: (child’s age in years/20) x adult dose.
