    Study Notes

    Principles of Aseptic Techniques & Standard Precautions

    • Aseptic techniques and methods prevent the introduction, growth, and spread of microorganisms.
    • Clean technique (medical asepsis) aims to reduce bacteria, preventing spread.
    • Sterile technique maintains a germ-free environment, crucial for invasive procedures.

    Learning Objectives

    • Students will be able to explain general principles of asepsis.
    • Students will be able to explain standard precautions and infection control measures.
    • Students will be able to identify elements of standard precautions.
    • Students will be able to identify disease transmission modes and infection chains.
    • Students will be able to highlight steps in handwashing.
    • Students will be able to state guidelines related to asepsis and standard precautions.

    Infection Process and Modes of Disease Transmission

    • The invasion of bodily tissue by pathogenic microorganisms.

    • Germ transmission can occur via touching, eating, drinking, or breathing.

    Infection Process and Modes of Disease Transmission (cont.)

    • Infection process steps for transmission include: causative agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host.

    Chain of Infection

    • Showing relationships between each aspect of chain of infection.
    • Visual representation of causative agents and reservoir relations.

    Causative Agent

    • Microorganisms like bacteria, viruses, and fungi.

    Reservoir (Source)

    • A host where microorganisms live, grow, and multiply (humans, animals, and environment).

    Portal of Exit

    • The path for microorganisms to leave the host.
    • Includes respiratory tract, skin, mucous membranes, genitourinary tract, gastrointestinal tract, and transplacental route.

    Mode of Disease Transmission

    • Microorganisms need a vehicle for spreading to other people and places. This includes: air-borne, contact (direct and indirect), vehicle (water, milk, food), vector-borne, and transplacental.

    Portal of Entry

    • The path for the microorganism to enter a new host.

    Susceptible Host

    • A person who is susceptible to the microorganism.
    • CDC guidelines and recommendations for infection control in healthcare settings (procedures for infection control, exposure occurrences, etc.)
    • Standard precautions: the foundation of infection prevention and control emphasizes the proper implementation of standard precautions.
    • Hand hygiene, use of PPE when appropriate, safe injection/ handling of contaminated equipment, respiratory hygiene.
    • Hand Hygiene: Importance of proper hand hygiene to prevent infection.
    • PPE Use: Instructions and training on using gloves, gowns, masks, and eye protection.
    • Respiratory Hygiene: Steps for stopping the spread of respiratory illnesses (using tissues, coughing/sneezing manners).
    • Exposure Incidents: Actions to take in case of exposure to bodily fluids, needlesticks (washing, reporting, emergency care).
    • Transmission-Based Precautions: Categorization of precautions based on how infections are transmitted (contact, droplet, airborne).
    • Contact Precautions: Using gloves, gowns, medical equipment, and thorough surface disinfection.
    • Droplet Precautions: Wearing masks, maintaining distance from the patient, and placing the patient in a private room.
    • Airborne Precautions: Using specific respirators, placing the patient in a room with low pressure, and restricting movement.
    • OSHA (Occupational Safety and Health Administration): Rules and regulations regarding bloodborne pathogens, ensuring worker safety.
      • Bloodborne Pathogens Standard: Protecting healthcare workers from bloodborne pathogens (HIV, HBV, HCV).
    • Exposure control strategies: steps for preventing employee exposure to blood and other potentially infectious materials.
    • Methods for Reducing Infection: Engineering controls (e.g., sharps containers, needleless systems), work practice controls (hand washing techniques, PPE use, etc.).
    • Personal Protective Equipment (PPE): Providing employers with the appropriate PPE (gloves, masks, gowns, eye protection).
      • Training and maintenance of safety protocols.
    • Hepatitis B Vaccination: Offering the Hepatitis B vaccine series to prevent Hepatitis B.

    Employee Training and Recordkeeping
