frequent hand washing and proper linen-handling
procedures.
HAND WASHING.The following are some
common instances when provider hand washing is
imperative:
Before and after each patient contact
Before handling food and medications
After coughing, sneezing, or blowing your nose
After using the toilet
LINEN HANDLING.Improper handling of
linen results in the transfer of pathogenic organisms
through direct contact with the healthcare providers
clothing and subsequent contact with the patient,
patient-care items, or other materials in the care
environment.
Proper linen handling is such an
elementary procedure that, in theory, it seems almost
unnecessary to mention. However, it is a procedure so
frequently ignored that emphasis is justified.
All linen, whether clean or used, must never be
held against ones clothing or placed on the floor. The
floors of a healthcare facility are considered to be
grossly contaminated, and, thus, any article coming in
contact with the floor will also be contaminated. Place
all dirty linen in appropriate laundry bags. Linen from
patients having infectious or communicable diseases
must be handled in a special manner.
Isolation Technique
Isolation technique, a medical aseptic practice,
inhibits the spread and transfer of pathogenic
organisms by limiting the contacts of the patient and
creating some kind of physical barrier between the
patient and others. Isolation precautions in hospitals
must meet the following objectives. They must
be epidemiologically sound;
recognize the importance that body fluids,
secretions, and excretions may have in the
transmission of nosocomial (hospital
originating) pathogens;
contain adequate precautions for infections
transmitted by airborne droplets and other routes
of transmission; and
be as simple and as patient friendly as possible.
In isolation techniques, disinfection procedures
are employed to control contaminated items and areas.
For purposes of this discussion, disinfection is
described as the killing of certain infectious
(pathogenic) agents outside the body by a physical or
chemical means. Isolation techniques employ two
kinds of disinfection practices, concurrent and
terminal.
CONCURRENT DISINFECTION. Con-
current disinfection consists of the daily measures
taken to control the spread of pathogenic organisms
while the patient is still considered infectious.
TERMINAL DISINFECTION.Terminal
disinfection consists of those measures taken to
destroy pathogenic organisms remaining after the
patient is discharged from isolation. There are a
variety of chemical and physical means used to
disinfect supplies, equipment, and environmental
areas, and each facility will determine its own
protocols based on the recommendation of an Infection
Control Committee.
SURGICAL ASEPTIC TECHNIQUE
LEARNING OBJECTIVE: Recall the
principles and guidelines for surgical aseptic
technique, and determine the correct
sterilization process for different types of
materials.
As used in this discussion, surgical aseptic
technique is the term used to describe the sterilization,
storage, and handling of articles to keep them free of
pathogenic organisms. The following discussion will
address the preparation and sterilization of surgical
equipment and supplies, and the preparation of the
operating room for performing a surgical procedure. It
should be noted that specific methods of preparation
will vary from place to place, but the basic principles of
surgical aseptic technique will remain the same. This
discussion will present general guidelines, and
individual providers are advised to refer to local
instructions regarding the particular routines of a
specific facility.
Before an operation, it is necessary to sterilize
and keep sterile all instruments, materials, and
supplies that come in contact with the surgical site.
Every item handled by the surgeon and the surgeons
assistants must be sterile. The patients skin and the
hands of the members of the surgical team must be
thoroughly scrubbed, prepared, and kept as aseptic as
possible.
