Title: Aseptic Technique

Aseptic Technique
  • Information Taken from D.McAuley
  • Global RPh Inc

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 bodys natural barriers.

So What is a Laminar Flow Hood !
  • It has a high efficiency bacteria-retentive
  • 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

Vertical Laminar Hood
Horizontal Laminar 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

Remember !
And Never Forget This!
  • 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.

  • 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
