    Medical Asepsis Medical Asepsis Presentation Transcript

    • MEDICAL ASEPSIS
    • MEDICAL ASEPSIS
        • All practices intended to confine a specific microorganism to a specific area, limiting their number, growth, and transmission. (Clean/ dirty/ contaminated)
        • Procedures used to protect the client and his environment from the transmission of disease producing organisms that can transmit from one to the other
    • METHODS OF MEDICAL ASEPSIS
      • Isolation precautions
      • Hand washing
      • Use of gown, mask, gloves, glasses
      • Use of disposables, clean surfaces
      • Concurrent and terminal disinfection
      • Control and teaching of visitors/ relatives
      • Developing staff health and hygiene and education
      • Preventive vaccination, inoculation and medicines
      • Use of labour saving and efficient devices for aseptic practices
    • ISOLATION PRECAUTIONS
      • Isolation – Measures to prevent the spread of infections or potentially infectious organisms to health personnel, client and visitors
      • Barrier technique (Reverse isolation) - Measures to protect highly susceptible (compromised) clients from infection
    • ISOLATION SYSTEMS USED IN HEALTH CARE AGENCIES
      • Centers for Disease Control & prevention (CDC) precaution – involves procedures for -
          • Category specific Isolation (CSI) precaution
          • Disease specific isolation (DSI) precaution
          • Universal precaution
      • Body Substance Isolation (BSI) system
    • CDC ISOLATION PRECAUTIONS…
      • Category Specific Isolation- Based on 7 categories-
      • 1. Strict Isolation
      • 2. Contact Isolation
      • 3. Respiratory Isolation
      • 4. TB Isolation
      • 5. Enteric precautions
      • 6. Drainage/ secretions precautions
      • 7. Blood/ body fluid precautions
    • CDC ISOLATION PRECAUTIONS…
      • Disease Specific Isolation – According to specific disease conditions
      • Universal Precautions – Blood and body fluid precautions.
        • Decrease the risk of transmitting unidentified pathogens
        • Hepatitis B, C, and HIV
        • Does not apply to feces, nasal secretions, sputum, sweat, tears, urine, vomitus unless they contain visible blood
        • Used in conjunction with CSI & DSI
    • BODY SUBSTANCE ISOLATION
      • Includes all body parts and secretions and excretions
      • Does not include clients with airborne diseases
      • Follows hand washing, gloving, gowning, wearing masks, eye wear, hair and shoe covers
      • Adheres to needle destruction and disposal and proper disposal of waste
    • IMPLEMENTING ISOLATION PRECAUTIONS
      • A nursing responsibility
      • Based on comprehensive assessment of the client
        • Status of client’s defense system
        • Client's ability to implement isolation
        • precautions
        • Source and mode o transmission of infectious
        • agent
      • Follow specific precautions during therapies for client’s benefit
      • Decision made on the method of isolation precaution
    • HAND WASHING
      • Cut nails short, remove all jewelry, check for breaks/ cuts in the skin

    • USE OF FACE MASKS
      • To reduce risk of transmission by droplet contact, air borne routes and splatters of body substances
      • To be worn by –
        • Those close to the client (in measles, mumps, Ac resp diseases) – large particle aerosols travel short distances (1 m of 3 ft)
        • All persons entering the room ( in Pulm TB)- small particle aerosols remain suspended in the air, and thus travel great distances
      • Masks – Should have good filtration effectiveness and fit
      • - Do not carry them in the pocket or around the neck
