Chapter 6- Infection prevention Flashcards
Cs infection prevention
Cleaning contaminated devices to make them for handling and prepare for brocidal process
Inspect them to ensure the are safe and functional
Assemble and package that facilitates sterilization and provides barer after sterilization
Selecting and using proper methods and HLDFollowing IFU
Safely store until needed and deliver with proper methods to keep sterile
SSI
Surgical site infection occurs after surgery in the part of the body where it took place.
Chain of infection
Gather info needed to inturmipt or prevent infection
Breaking link= disrupt infection. Which link is most effective to target will depend on organism
Asepsis
Absence off micro. That cause disease
A septic technique
Procedure that prevents infection or breaks chain of infection
Medical asepsis (clean technique)
Procedures performed to reduce the number of micro. To minimize spread
Decontamination of equipment or washing hands
Surgical asepsis ( sterile technique)
Procedures eliminate presence of all micro. And prevent intro of micro. To an area.
Five principles of asepsis
- Know what is dirty
- Know what is clean
- Know what is sterile.
4 keep the 3 conditions separate - Remedy contamination immediately
Hand hygiene
Washing with soap and water or alcohol-based hand rub
Donned
Put on prior to starting shift
Dotted
Removed before leaving work
Donning protocol
Surgical scrubs, head cover and appro. Shoes Gown/ jumpsuit Mask Goggles or face shield Shoe coverings Gloves
Dotting protocol
Remove shoe covers Remove gloves Remove goggles or shield Remove gown Remove mask Remove head cover then wash hands
Restricted
Sterile surgical procedures preformed
Scrubs, hair cover, masks
Semi-restricted
Peripheral support areas to OR
Clean assembly, and sterile storage areas
Scrubs, hair cover,
Unrestricted
Normal Traffic areas
Street clothes
Biohazard
Red, or orange use label
Waste containers
Sharps in a puncture proof container that’s covered
Reusable are transported in enclosed carts or hard-sided containers
Decontaminated air flow
Negative (lesser) pressure
Clean air flow
Positive pressure
Famines
Inanimate object that can transmit bacteria
Decontamination room requirements
T- 60-65°f (16-180c)
Humidity- 30-60%
Air exchange- 10
General work area requirements
T- 68-73°f (20-23°)
Humidity -30-60%
Air exchange- 10
Sterile storage
T- 75°f or lover
Humidity - not exceed 70%
Air exchange-4
Sterilization equipment room requirements
T- 75-85°f (24- 29° c)
Humidity -30-60%
Air exchange-10
Causative agent
Chain of infection
Micro. That causes infectious disease
Bacteria, vines, fungus, Protozoa or prion
Reservoir
Chain of infection
Place where micro. Can survive.
Carrier. Organism infected but no symptoms displayed can still transmit tocthers
Portal of exit
Chain of infection
Path which infectious agent leaves resovior
Coughing, sneezing, urine vaginal secretions, semen, vomit, stool, mucusmemb, wound, blood, transplacental
Mode of transmission
Chain of infection
Meth of transfer of infectious agent from resavior to susceptible host
Direct, indirect ( through object), droplets, airborne nvectorborre, pathogenic transmission→ interrupted with proper hygiene and PPE, etc.
Portal of entry
Chain of infection
Path used by infect. Agent to enter most
Rest, genitourinary, gi, skin and mmb, transplacental
Parenteral= something put inside body but not swallowed (ex. injection)
Susceptible host
Chain of infection
Person or animal that lacks ability to resist infection by agent
Colonization= when micro. Live on or in host and do not harm or damage
Chain of infection
Causative agents → reservoir→ portal of exit → mode of transmission → portal of entry → susceptible most
Characteristics that make micro. Capable of causing disease
- Invasiveness: ability to invade and cause damage
- Pathogenicity: to gain entry and cause dz.
- Virulence: degree of pathogenicity
- infectious dose: quant ay of micro. Required
- Viability in a free state: a bitty to survive outside host
- ability to develop resistance to antimicrobial agents
Interrupting chain
Use aseptic technique to avoid cross contamination, physically removing contaminated substances, use effective disinfection and sterilization
Susceptible host factors
- age
- dz. History
- meds and tx→ compromise immune system
- Trauma
