pt 5 Essentials of Patient Care for the Sonographer

Sterilization and Disinfection of Transducers

  • Transducer Sterilization

    • Critical devices (enters sterile body cavities or vascular system) must be free from all microbial life.
    • Ultrasound transducers are difficult to sterilize, but high-level disinfection (HLD) is acceptable with sterile covers.

  • Importance of Disinfection

    • To prevent infections, ensure patient safety, and maintain the reputation of sonography.
    • Contaminated transducers can lead to serious infections (e.g., VRE, MRSA).
    • Studies indicate failures even after low-level disinfectants.

  • Recommendations

    • Understand Spaulding's Classification for equipment disinfection.
    • Implement regular cleaning protocols for the ultrasound room and equipment.
    • Store transducers in enclosed cabinets and manage gel bottles carefully to minimize bacterial growth.

Hand Hygiene

  • General Hand Hygiene Practices

    • Wash hands before and after patient contact.
    • Use soap and water especially after contact with contaminants; alcohol-based sanitizers can be used if soap isn’t available.
    • Wash hands after using the restroom, before eating, and after contact with any potentially infectious material.

  • Recommended Handwashing Technique (CDC)

    1. Wet hands with running water, apply soap.
    2. Lather by rubbing hands for at least 20 seconds (sing "Happy Birthday" twice).
    3. Rinse under running water.
    4. Dry with a clean towel or air dry.

Isolation Precautions

  • Goal of Isolation

    • Prevent spread of communicable diseases among patients and healthcare workers.
    • Understand facility-specific isolation guidelines.

  • Standard and Additional Precautions

    • Follow Standard Precautions including PPE use and hand hygiene.
    • Recognize need for additional precautions based on specific pathogens:
    • Airborne Precautions: Protect against diseases that can travel via air (e.g., TB).
    • Droplet Precautions: Protect from pathogens in respiratory droplets (e.g., influenza).
    • Contact Precautions: For infections spread by contact (e.g., MRSA).

Personal Protective Equipment (PPE)

  • PPE Importance

    • Protects healthcare workers from exposure to infectious agents.
    • Includes gloves, gowns, masks, and eye protection.

  • Proper Usage of PPE

    • Donning: Sequence must be followed for safety:
    1. Hand hygiene.
    2. Gown.
    3. Mask.
    4. Eye protection.
    5. Gloves.
    • Doffing: Remove PPE in reverse order without contamination.
    1. Remove gloves.
    2. Gown.
    3. Eye protection.
    4. Mask.

Handling Blood-Borne Pathogens

  • Blood-Borne Disease Risks
    • HIV and Hepatitis C can be transmitted through contact with infected blood.
    • Sonographers may risk exposure from needle sticks; therefore, safety protocols must be followed immediately if an incident occurs.

Conclusion

  • Maintain vigilance in infection control practices, including hand hygiene and awareness of the proper use of isolation precautions and PPE to ensure both patient and practitioner safety in healthcare settings.
  • Regularly update knowledge of protocols as they may differ among facilities.
