Tante Girang The formula to calculate drug dosages and IV drip rate



Drugs and measuring the size information
The part about the drug dose is based on the book Henney CR et al, 1995, Drugs in nursing practice, 5th ed (Churchill Livingstone, Edinburgh) and formulary book from Harvard M 1994, A nursing guide to drugs, 4th ed (Churchill Livingstone , Edinburgh), quoted with permission. The introduction of metric measures in practice medic has changed the way to express the dose and concentration of the drug, the patient data (including height, weight and body surface area), drug levels in the body and the results of other measurements.

weight loss
Unit weight is the kilogram (kg) consisting of 1000 grams (g); every gram is composed of 1000 milligrams (mg). Each is composed of 1000 micrograms milligrams (1.4g or mcg).
If the drug is prescribed in doses of micrograms AWL, this unit should be fully written, eg. Digoxin 250 micrograms, because abbreviations such as tig or mcg in practice can be confused into temporary mg mg dose a thousand time bigger so bring consequences that could harm. Drug doses are often expressed in dose units per kg body weight, eg. mg / kg, micro g / kg, etc.. Dose method is often used in pediatrics and allows dosing are made in accordance with the size of the individual patient.


volume
Liter unit volume is expressed by the symbol 'l​​' A liter consisting of 1000 milliliters (ml). The symbol 'l​​' or `ml 'is used in almost any size in unit volume for writing prescriptions and drug administration.

concentration
There are several ways that can be used in expressing concentrations of a drug dose of a liquid:
Unit weight per unit volume
This method describes the unit weight of a drug contained in unit volume, eg. 1 mg in 1 ml, 2 mg in 1 ml of 40 mg in 2 ml, and so on. Examples of drugs commonly expressed in this way are: injection diazepam 10 mg in 1 ml mixture of 1 g of chloral hydrate in 10 ml suspension Penicillin V 250 mg in 5 ml.
