Transcript

  • 1. Infection Control Process
    • Lister, Pasteur and Semmelweis were the first to contribute about germ theory
    • Microorganisms
    • Protozoonology,Bacteriology, Virology,Mycology
    • Bacteria (most numerous of all microorganisms, unicellular, many are pathogenic to human
    • Cocci,Bacilli and Spirilla
    • Can be killed with antibiotics
  • 2. Fungy and Bacteria
  • 3. Cocci and Protozoa
  • 4. Fungi
    • Parasistic and some none parasistic plants and molds
    • Yeast is a typical fungus
    • Feed on antibiotics and flourish in antibiotic therapy
  • 5. Protozoa
    • One cell organisms
    • Both parasite and non parasite
    • can move with cilia or false feet
    • typically 2 to 200 mm in size
  • 6. Virus
    • Smallest of all microorganisms
    • can be seen only with electronic microscope
    • can only multiply within a living cell
    • can be destroyed by heat
    • difficult to kill with chemotherapy
  • 7. Ricketssia
    • Visible under a standard microscope
    • Susceptible to antibiotics
    • transmitted by insects, ticks, fleas
  • 8. Conditions Required for bacterial Growth
    • Moisture
    • Temperature
    • Oxygen
    • Light
  • 9. Transmission of infections
    • The pathogen needs to be present
    • A reservoir of disease
    • a portal of exit from the reservoir
    • a means of transmission
    • a portal of entry
    • a susceptible host
  • 10. Stages of Infection Process
    • Invasion
    • Multiplication
    • Incubation Period
    • Prodromal Period
    • Acute Period
    • Recovery Period
  • 11. The Infection Control System
    • Defenses of the body (Dietary Intake, age of person,adequate amount of rest, presence of other disease in the body, genetics)
    • Prevention: Barriers of the body, skin, mucous membranes, Ph acid,HCL in the stomach, etc
    • Lymphoid and Blood System
    • Antigen-Antibody ( Immunity)
    • Inflammatory Process
  • 12. Acquired Immunity
    • Active Acquired Natural (by having the disease)
    • Active Acquired Artificial ( Vaccination)
    • Passive Acquired Natural (Antibodies from the mother to the baby)
    • Passive Acquired Artificial (temporary protection with globulins)
  • 13. Standards Precautions
    • Gloves
    • Gown
    • Mask/Protective Eyewear/goggles
    • Transportation
    • Multiple use equipment
    • Needles and sharp instruments
  • 14. Medical Asepsis
    • Destruction of organism after they leave the body:
    • Washing Hands
    • Use of disposable equipment
    • Wearing gloves helps
  • 15. Handwashing
    • First stage of infection control
    • Use disinfectants soap, friction and warm running water
    • No jewelry
    • Before and after a contact with a patient
  • 16. Surgical Asepsis
    • Refers to the techniques practiced to maintain a sterile environment. Destruction of the microorganism before they enter the body
    • There are 3 methods for preventing the spread of disease:
  • 17. Surgical Asepsis
    • Sanitization (includes the careful scrubbing of equipment and instruments with soap, hot water, U/S,etc
    • Disinfection (soaking and wiping process with chemicals germicides, flowing steam and boiling water
  • 18. Surgical Asepsis
    • Two common disinfectants are zephrin chloride and chlorophenyl
    • Disinfectants are not efective against spores and some viruses
    • Betadine and alcohol are used in patients
  • 19. Disinfection Methods
    • Alcohol (used for skin surfaces and equipment such stethoscopes and thermometers, flammable
    • Chlorine (corrosive,cause skin irritation
  • 20. Disinfectants
    • Formaldehyde( use to disinfect and sterilze)
    • Hydrogen Peroxide (effective disinfectant only for use in non-human surfaces and products)
    • Glutaraldehyde (efective against viruses, bacteria and fungi
  • 21. Sterilization
    • Results in killing ALL microorganisms, both pathogenic and non pathogenic.
    • The use of heat (steam or dry)chemicals,UV radiations.
    • Dry heat is used for dense ointments
  • 22. Sterilization Time
    • Glassware, metal instruments (open tray or individual wrappings) needles
    • 15 minutes
    • Rubber products, Instruments partial metal
    • 20 minutes
  • 23.
