    Infection Control Infection Control Presentation Transcript

    • 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
    • Fungy and Bacteria
    • Cocci and Protozoa
    • Fungi
      • Parasistic and some none parasistic plants and molds
      • Yeast is a typical fungus
      • Feed on antibiotics and flourish in antibiotic therapy
    • Protozoa
      • One cell organisms
      • Both parasite and non parasite
      • can move with cilia or false feet
      • typically 2 to 200 mm in size
    • 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
    • Ricketssia
      • Visible under a standard microscope
      • Susceptible to antibiotics
      • transmitted by insects, ticks, fleas
    • Conditions Required for bacterial Growth
      • Moisture
      • Temperature
      • Oxygen
      • Light
    • 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
    • Stages of Infection Process
      • Invasion
      • Multiplication
      • Incubation Period
      • Prodromal Period
      • Acute Period
      • Recovery Period
    • 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
    • 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)
    • Standards Precautions
      • Gloves
      • Gown
      • Mask/Protective Eyewear/goggles
      • Transportation
      • Multiple use equipment
      • Needles and sharp instruments
    • Medical Asepsis
      • Destruction of organism after they leave the body:
      • Washing Hands
      • Use of disposable equipment
      • Wearing gloves helps
    • Handwashing
      • First stage of infection control
      • Use disinfectants soap, friction and warm running water
      • No jewelry
      • Before and after a contact with a patient
    • 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:
    • 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
    • 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
    • Disinfection Methods
      • Alcohol (used for skin surfaces and equipment such stethoscopes and thermometers, flammable
      • Chlorine (corrosive,cause skin irritation
    • 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
    • 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
    • Sterilization Time
      • Glassware, metal instruments (open tray or individual wrappings) needles
      • 15 minutes
      • Rubber products, Instruments partial metal
      • 20 minutes
