Nurses also need to understand how to calculate how much of a drug the patient will receive if the fluid rate changes. Once a CRI is utilized, the fluid rate should be checked **at least every 4 hours** and matched to the medical record ordered dose.

## How do you calculate CRI infusion?

Medical Math – Constant Rate Infusion

- Calculations for Fluids Running at a Pre-Set Rate.
- For example, a 17 kg dog has fluids running at 65 ml/hr.
- (1mg/kg/day means the dog needs 17mg/day (24 hours) of metoclopramide)
- 1000 ml/L ÷ 65 ml/hr = 15.4 hr/L.
- 15.4 hr/L x 0.7 mg metoclopramide/hr = 10.8 mg metoclopramide/L.

## How do you calculate a CRI dog?

Example: a 15 kg dog has been battling hypotension and you are asked to calculate a dopamine (40 mg/ml) CRI, and then start administering 5 μg /kg/min to the dog. For ease of titrating, you will make the CRI so that 1 ml/hr = 1 μg/kg/min. You will be making the CRI in a 100 ml bag of NaCl.

## What is a cri in vet med?

A Constant Rate Infusion (CRI) is used to deliver a controlled and continuous rate of medication over time. Since a CRI allows more precise delivery of medication, it provides maintenance of therapeutic levels of medication and helps avoid the unwanted dose-related side effects of bolus administrations.

## What is continuous rate infusion?

A continuous rate infusion (CRI) is a dosing regimen used to deliver a constant amount of drug per unit time. The most common CRIs are administered intravenously; however, other methods such as transdermal deliver mimic the characteristics of CRIs.

## What is a good CRI?

Incandescent and halogen light sources have a CRI of 100. Typically, light sources with a CRI of 80 to 90 are regarded as good and those with a CRI of 90+ are excellent! The general rule is: The higher the CRI, the better the color rendering capacity. CRI is independent of color temperature.

## When is it appropriate to give medication as an infusion?

Guidelines. Drugs should only be added to infusion containers when constant plasma concentrations are needed or when the administration of a more concentrated solution would be harmful. In general, only one drug should be added to any infusion container and the components should be compatible.

## How do you calculate dextrose CRI?

1) Easy VETgirl dextrose shortcut for CRI solutions: – To make a 2.5% solution add 50mL of 50% dextrose (or 25g dextrose) to a 1L bag of fluids. – To make a 5.0% solution add 100mL of 50% dextrose (or 50g dextrose) to a 1L bag of fluids.

## How many mg is 2 lidocaine?

Each 2 ml solution contains 40 mg Lidocaine Hydrochloride E.P.

## How do you give a CRI?

In these situations, the CRI is calculated so that 1 ml/hour = 1 μg/kg/hour. This way, the maths is done prior to the fluid rate change. Because 1 ml/hour = 1 μg/kg/hour, a fluid rate of 5 ml/hour will deliver 5 μg/kg/hour.

## How do you convert mg/kg to day?

The calculation is based on your weight in pounds (lb), and your daily mg dose of medication. Weight in pounds is converted to kilograms (kg) by dividing by 2.205. Weight in kg is then divided into the daily mg dose of medication to give the dose calculated as mg/kg/d.

## How is infusion administered?

IV Therapy is delivered intravenously via a syringe directly into a vein by means of a vascular access device. A bolus injection can be a once only injection or regular intermittent injections.
