How much maintenance fluid would a patient receive if they are 18 kg?
| Weight Minimum fluid intake per hour Minimum fluid intake per shift | 17 kg 54 cc/hour 432 cc/shift | 18 kg 56 cc/hour 448 cc/shift | 19 kg 58 cc/hour 464 cc/shift |

How is daily maintenance fluid calculated?
- 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?
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 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 IV fluids?
How do you calculate dehydration fluids?
- For children with ≤5% dehydration, replace deficit in the first 24 hours.
- For children with >5% dehydration, replace deficit more slowly.
What is the most common IV fluid given?
Crystalloid solutions
: These are the most common types of IV fluid. They contain small dissolved molecules that pass easily from the bloodstream into tissues and cells. Examples include normal saline, which is salt in water, and D5W, which is dextrose (sugar) in water.
How much IV fluids should be given for dehydration?
Plan on
two tablespoons (30 mL) per 2.2 pounds of body weight (or 1 kg)
. Plan on the administration to take about an hour. For a 130-pound woman, that would be about two-liter bags of treatment for complete dehydration therapy.
How much IV fluid is given for dehydration?
The fluid deficit in severe dehydration equals about 10% of body weight (i.e., 100 ml/kg). Infants should be given IV fluid at a rate of
30 ml/kg in the first hour, followed by 70 ml/kg in the next 5 hours
, thus providing a total of 100 ml/kg in 6 hours.
How do you calculate maintenance fluid in DKA?
- Maintenance fluids are calculated using the standard (Holliday-Segar) formula:
- General Principles:
- ALWAYS recheck the fluid calculation; errors occur frequently.
- Total hourly fluid rate =
- Total Deficit / 48 in mL + calculated hourly maintenance in mL.
How many drops are in 1 mL of IV fluid?
Drop factor = the number of drops it takes to make up one ml of fluid. Two common sizes are:
20 drops per ml (typically for clear fluids) 15 drops per ml (typically for thicker substances, such as blood)
How do you regulate IV flow rate?
IV fluid rates are regulated in one of two ways: Gravity. The health care provider regulates the infusion rate by
using a clamp on the IV tubing
, which can either speed up or slow down the flow of IV fluids. An IV flow rate for gravity is calculated in gtts/min.
When do you give maintenance fluids?
Maintenance fluid therapy is indicated for
patients that are not eating or drinking, but do not have volume depletion, hypotension, or ongoing losses
. Replacement fluids (e.g., LRS) are intended to replace lost body fluids and electrolytes.
How do you calculate IV fluids for adults?
- 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.
How long do IV fluids last?
The effects can last for up to a few days after completing the procedure, depending on a number of different factors. The average IV treatment for us lasts
45 minutes to an hour
.
Which IV fluid is best for weakness?
Lactated Ringer’s Solution
(also known as Ringer’s Lactate or Hartmann solution) is a crystalloid isotonic IV fluid designed to be the near-physiological solution of balanced electrolytes.
How many IV fluids are there?
There are
three types
of IV fluids: isotonic, hypotonic, and hypertonic.
