Aseptic Technique Information Taken from D.McAuley Global RPh Inc www.globalrph.com/aseptic.htm
Some Important Rules(ASA) • Always think of the patients • Safety: The finished product must be free of contamination. The solution should be clear. All medications should be completely dissolved. All compounding medications should be checked for expiration date • Accuracy (3Rs): Right Drug, Right Medication, and Right Concentration
Dangers of Poor Aseptic Technique • Infections • Emboli • Occlusion • AND even Death The IV route is the most dangerous route of administering drugs because it bypasses all of the body’s natural barriers.
So What is a Laminar Flow Hood ! • It has a high efficiency bacteria-retentive filter • Room air is taken into the unit and passed through a pre-filter to remove gross contaminants (lint, dust, etc) • The air is then compressed and channeled up behind and through the HEPA filter in a laminar flow fashion ( purified air flows out over the entire work surface in parallel lines at a uniform velocity. • The HEPA filter removes nearly all of the bacteria from the air
Why Control Rom Air? Room air may be highly contaminated. Example: sneezing produces 100,000-200,000 aerosol droplets which can then attach to dust particles. These particles can stay for weeks.
How Long Should the Laminar Hood Remain On? • It should be on 24 hours a day. If turned off for any reason, it should be on for at least thirty minutes and thoroughly cleaned before reusing
Kinds of Laminar Flow Hoods There are two kinds in general: • Vertical Hood • Horizontal Hood
Precaution with Horizontal Laminar Flow Hood • When working in a horizontal laminar flow hood, all work must be performed at a distance of no less than 6 inches from the front edge of the work surface. At a distance of less than 6 inches, laminar flow air begins to mix with the outside air and contamination is possible. Never become so engrossed in your work that you forget this basic rule
Also • when pulling back the plunger of a syringe, the fingers should not come in contact with any part of the plunger--except the flat part at the end. Poor manipulation of the syringe is the most frequent cause of contamination. • Waste and other items should never enter the hood. All calculations should be done before entering the hood.
AND • Wash hands and arms before compounding or re-entering the hood • Remove any jewelry from the hands and wrists. • Always disinfect all rubber stoppers and ampul necks with alcohol before entering with a needle
How to Clean the Hood • Before and after preparing a series of IV admixtures, or anytime something is spilled, the work surface of the laminar flow hood should be thoroughly cleaned with alcohol. A long side to side motion should be used starting at the back of the hood and then working forward. The acrylic plastic sides should also be cleaned periodically.
