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
  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

5
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.

6
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

7
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

11
Remember !
12
And Never Forget This!
13
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.

14
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

15
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.
