Being sterile means being free from microorganisms and being pyrogen-free means being free from fever-causing substances. The difference can be likened to insects and their eggs.
Good examples of pyrogen-producing gram-negative bacteria are Escherichia coli (E. Coli), Proteus, Pseudomonas, Enterobacter, and Klebsiella (Dixon, 2001).
Endotoxin can be inactivated when exposed at temperature of 250º C for more than 30 minutes or 180º C for more than 3 hours (28, 30). Acids or alkalis of at least 0.1 M strength can also be used to destroy endotoxin in laboratory scale (17).
Oxidation using hydrogen peroxide is often used as a low cost pyrogen destroying solution. The mechanism for this destruction is unknown, but hydrogen peroxide can easily be removed further downstream in the purification process, and is therefore a useful method of pyrogen removal.
Distilled water will also be free of virtually any chemicals. In summary, distilled water is sterile, but sterile water isn't always distilled. Distillation takes it another step toward perfection. Distilled water is still your best choice.
Testing for pyrogens is a requirement for all parenteral products including injectable vaccines, and there have traditionally been two tests for pyrogenicity: the rabbit pyrogen test (RPT) and the Limulus amebocyte lysate (LAL) test.
Fever is caused by chemicals known as pyrogens, flowing in the bloodstream. Normally, pyrogens help the immune system by fighting infectious agents, such as bacteria and viruses-- which are sensitive to temperature changes.
Sterilization is a process of removing all microorganisms from the process, whereas depyrogenation is the process of removing pyrogens from the process.
I found early on that the nurses very seldom flush their IVs (not after giving medication, not after insertion with blood draw), but just discovered that when they DO flush them, they use straight "sterile water for injection". A quick search here and on a drug site showed that this is absolutely not acceptable.
Sterile water is characterized as water that is free of all micro organisms (like fungi, spores, bacteria etc. A distinction should further be made between sterile water and saline solution. Sterile Saline solution has 0.9% Sodium Chloride and is used for wound irrigation and cleaning.
Sterile water for injection is 0 mOsm/L, which can be fatal. It should never be given intravenously to patients. PA-PSRS and other medication error reporting pro- grams have received reports of events involving the IV administration of sterile water to patients.
Sterile Water for Injection, USP, is sterile, nonpyrogenic, distilled water in a single dose container for intravenous administration after addition of a suitable solute. It may also be used as a dispensing container for diluent use. No antimicrobial or other substance has been added.
Sterile Water For Injection is an over-the-counter product used to dilute medications or to help deliver medication in a liquid form. This product is available in the form of an injectable solution and is not currently covered by Medicare. There is no generic alternative available.
For Sterile Water for Inhalation in containers having a fill volume of less than 50 mL, add 0.4 mL of 0.02 M potassium permanganate, and boil for 5 minutes; where the fill volume is 50 mL or more, add 0.2 mL of 0.02 M potassium permanganate, and boil for 5 minutes.
Sterile 0.9% saline is an isotonic solution. It neither donates fluid nor draws it away from the wound bed (Blunt, 2001).
Serious adverse reactions, including cerebral or pulmonary edema, massive hemolysis, and acute renal failure can result from the hypotonicity of Sterile Water for Irrigation [see Warnings and Precautions (5.2)].
McKesson Irrigation Solution Sterile Water for Irrigation, Not for Injection, Bottle, Screw Top, 100 mL, Case of 48 - Walmart.com - Walmart.com.
Water for Injection is a solvent used in the production of parenteral and other preparations where product endotoxin content must be controlled, and in other pharmaceutical applications Water For Injection (WFI) is sterile, non pyrogenic, distilled water for the preparation of products for parenteral use.
The pyrogen test on rabbits is based on the measurement of the increase in the rabbit's temperature upon being injected with a product that could contain a contaminant of the pyrogen type. The pyrogens, as their name suggests, refer to all the substances that cause an increase in fever, also known as pyrexia.
Sterile Water for Irrigation USP is indicated for use as an irrigating fluid or pharmaceutic aid. Sterile Water may also be used as an adjunct in the preparation of non-intravenously administered nutrient mixtures (see DOSAGE AND ADMINISTRATION). Not for injection.
Surgeons use distilled water during medical procedures. Anyone practicing medicine likely uses distilled water to wash their hands, and in laboratories. The purity assures the safety of the patient, and it's imperative to the field.
Hypertonic saline (sterile salt water solution) breathed in as a fine mist using a nebuliser may help relieve wheezing and breathing difficulty.
Put the container in a pan of boiling water for 10 minutes. or Clean the container in a dishwasher on the full cycle (not a short wash). Put the mixture in a sterile container, write the date on a label, and put the sterile saline in the refrigerator.
