MEDICAL TERMS Flashcards
biosecurity
set of measures to PREVENT introduction and spread of infectious diseases
asepsis
ABSENCE of microorganisms that cause disease
> ANIMALS here=NOT STERILE
(sterile for instruments..)
here situation, GOAL
aseptic technique
METHOD TO PREVENT contamination by microorganism
antisepSIS
EXCLUSION, destruction or inhibition of growth or multiplication of microorganisms from body tissues and fluids
(what we can do to reach asepsis, ACTION>fighting against those bacteria>kill or physically remove from area>amount of bacteria on operative field is FIRST reduced)
antisepTICS
CHEMICAL COMPOUND inhibiting growth of microorganisms without necessarily killing them
sterile
FREEEEE of living organisms
(compare to:
> asepSIS=
not sterile, clean, animals
> antisepsis=clean, not sterile, able to cause disease - area that we will clean to fight against bacterias :kill or physically remove from area
> here (sterile) NONE of organism, not possible to sterile cat for example, only equipments etc, autoclave or products etc)
to sterile
TO MAKE object sterile
=destroy bacteria, virus, protozoa, fungi
=KILL bacteria and other organisms
-OBJECTS
sterile technique
-METHOD by which contamination with microorganisms is PREVENTED to MAINTAIN STERILITY throughout surgical procedure
-IDEAL GOAL
-PREVENT transmission of microorganisms into body during invasive procedures
1. sterile : personnel are gowned gloved, touch only sterile items/areas
2. sterile drapes
3.only sterile items within sterile field
4.sterile items opened, dispensed and transferred by methods that MAINTAIN sterility
5. field monitored 24/7 and surgical staff able to recognize when they have broken technique and act accordingly
(in restricted, surgical, area)
disinfection
CHEMICAL or MECHANICAL destruction of pathogens
-OBJECTS
decontamination
CLEANING and DISINFECTING or STERILIZING (objects!!!!items!!!!) processes carried out to make contaminated items safe to handle
infection
-INVASION and MULTIPLICATION of microorganisms (bacteria, viruses, parasites) that are NOT normally present at the site
-potentially devastating and challenging complication of surgery
-in hospital settings, transmission of microorganisms is most commonly contact-related
-all possible measures should be taken to reduce risk of iatrogenic infection (=infektio, joka tapahtunut toimenpiteen seurauksena, loss of asepsis)
> not part of normal microflora
harmful
NOT same as inflammation
cause: microorganism
to do: eliminate pathogen
(in inflammation=
cause: body’s own immune reaction
to do: immunosuppression)
draping
CREATING and MAINTAINING STERILE field around operative site with nonabsorbent towels
-performed by gowned and gloved team member when antiseptics have dried
-onea t time
-drapes should not be flipped or shaken
-once placed, not readjusted!!
-after animal and nearby non sterile surfaces have been covered with STERILE drapes, instrument tray can be arranged and surgery can begin
hemorrhage
=bleeding
-ABNORMAL escape of blood from artery, vein, arteriole, venue or capillary network
-caused by: traumatic injury/medical condition
-external/internal
-primary hemorrhage soon after injury
-2ndary follows injury after considerable lapse of time
-arterial/venous/capillary/parenchymatous
surgical site infection (SSI)
-infections that DIRECTLY result from surgical procedures
>INCISIONAL = actual site incision= superficial: skin and subcutaneous tissue =deep: deep soft tissue layers; muscle, fascia
-infection occurs within 30days of surgical procedure or within 1 year if associated with surgical implant
- ‘‘nothing spoils a good result as quickly as follow-up’’
> directly associated with surgery
implants
FOREIGN substances used to 1. support 2. rebuild 3. mimic function of anatomic structure
