## What Can Dehydration Cause?

Dehydration can lead to serious complications, including:Heat injury.

…

Urinary and kidney problems.

…

Seizures.

…

Low blood volume shock (hypovolemic shock)..

## What does maintenance fluid mean?

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.

## How do you prepare maintenance fluid in pediatrics?

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 421 rule?

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.

## What is the daily maintenance fluid requirement?

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.

## What is the daily fluid requirement?

So how much fluid does the average, healthy adult living in a temperate climate need? The U.S. National Academies of Sciences, Engineering, and Medicine determined that an adequate daily fluid intake is: About 15.5 cups (3.7 liters) of fluids a day for men. About 11.5 cups (2.7 liters) of fluids a day for women.

## 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.

## How do you calculate insensible fluid loss?

“Normal” Output:Urine: 800–1500 mL.Stool: 250 mL.Insensible loss: 600–900 mL (lungs and skin). (With fever, each degree above 98.6°F [37°C] adds 2.5 mL/kg/d to insensible losses; insensible losses are decreased if a patient is undergoing mechanical ventilation; free water gain can occur from humidified ventilation.)

## How do you calculate maintenance fluids?

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 is IVD calculated?

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.

## Is normal saline a maintenance fluid?

However, maintenance fluid also has to be administered. The volume of maintenance fluid for 24 hours is 1000 ml (100 ml/kg X 10 kg). This needs to be given as D5 0.33% saline….Replacement Fluid Therapy.0-8 hours9-24 hoursMaintenance333 ml of D5 0.33% saline666 ml of D5 0.18% saline2 more rows

## How do you fix fluid deficit?

The most cautious approach is to plan a slow correction of the fluid deficit over 48 hours. Following adequate intravascular volume expansion, rehydration fluids should be initiated with 5% dextrose in 0.9% sodium chloride. Serum sodium levels should be assessed every 2-4 hours.

## How do you calculate fluid intake for elderly?

Normal fluid intake A formula used to calculate fluid requirements for older people is: U 100 mL fluid per kg body weight for the first 10 kg U 50 mL fluid per kg for the next 10 kg U 15 mL fluid per kg for each kg after 20 kg.
