Infection Control
what can cause a risk to infection:
lowered resistance
disease process
medical therapy
What does Asympomatic mean?
Asymptomatic means a lack of clinical signs
What does sympotmatic mean?
you will have both local inflamtion & systemic reaction to infection
Inflammation includes:
swelling, redness,heat,pain, tenderness,WBCs up, exudate
Systemic response is like:
fever,WBCs up, malaise,anoxeria, nausea,vomiting, lympth node enlargement, confussion, behaviour changes
The chain of infection is
at the top infectious agent
left side has host and portal of entry
at right side we have reservoir and portal of exit
on the bottom there is mode of transmission
so what?
we need to break the chain of infection ... best way is to wash your hands
Name natural body defense system against infection
Normal Flora
so dont overdue it w/ bacterial soaps
also improperly administered antibiotics
what would be examples of natural organ defense systems against infection?
all these things fight infection naturally
There is the immune response of the body that includes:
cell mediated immunity
T lymphocyctes
What is CD4T?
T-cells or also called T-lymphocytes are WBCs. 2 types. CD4 on the surface targets viruses. CD8 destoy cells thate produce antiviral substances. HIV attaches itself to CD4 molecule, infects it, damaging its ability to fight viruses. Thus CD4 count reflects how many GOOD ones are in the blood
T cells or T lymphocytes are what?
lymphocytes, white blood cells. Think T for T rex, or natural killer cells, our immune system
What do these things contibute to?
disease process
medical therapy
increase the risk for infection
what is humoral immunity?
A form of immunity whereby B lymphocytes and plasma cells produce antibodies to foreign agents (antigens) and stimulate T lymphocytes to attack them (cellular immunity).
whats an example of natural immunity?
after receiving a disease, lasts a lifetime
what is artifical immunity?
receipt of a vacine, duration is variable
Passive immunity
transplanctally, short duration
Immunity produced by the transfer to one person of antibodies that were produced by another person. Protection from passive immunity diminishes in a relatively short time, usually a few weeks or months. For example, antibodies passed from the mother to the baby before birth confer passive immunity to the baby for the first 4-6 months of life
nosocomial infection is ...
what we do to other people by mistake in a hospital from:
long hair
acrylic nails
not washing hands
dirty on clean
improperly performed procedure
soiled clothes
we know what sterile techique is what is clean technique?
where sterile is to totally remove or prevent any infection, clean is to prevent infection and its spread. This is medical asepsis. prevent/reduce spread of microbes.
there is clean asepsis and sterile/surgical asepsis. clean is to control spread of infection by minimizing pathogens. what about sterile?
sterile technique is the complete elimination of pathogens or spores from an object or area
how do we control reservoirs?
remove, control drainage, secretions
proper disposal of contaiminated items, bags, collection bottles
proper dressing changes
room surfaces clean and dry
proper handling of bottles
proper handling of drainage tubes
fluid flows in the direction of
gravity. a sterile technique principle
lip of bottle
border of drape
edges of a sterile field or container are all
considered contaiminated
