Presentation Transcript

  1. Asepsis and Infection Control NUR 302 Professor Susan Blakey, RN, MS

  2. Infection Cycle

  3. Breaking the Chain of Infection

  4. Organisms Seen in Hospital • Staphylococcus aureus

  5. Organisms • Hepatitis B • Mycobacterium tuberculosis • Escherichia coli • Human Immunodeficiency virus

  6. Stages of Infection • Incubation

  7. Stages of Infection • Prodromal

  8. Stages of Infection • Full Stage Signs and symptoms • Convalescent Recovery

  9. Response to Infection • Normal Flora • Inflammatory Response

  10. Response to Infection • Immune Response

  11. At Risk for Infection • Integrity of skin and mucous membranes • Integrity of WBCs • Vulnerable populations • General Health Status • Stress Level • Indwelling devices

  12. Common Infections • Urinary Tract Infections (UTIs)

  13. Common Infections • Pulmonary Infections

  14. Common Infections • Skin Infections

  15. PREVENTION • Careful assessment • Early detection AND action • Immunizations • Assess for infections

  16. Laboratory Data Normal values are listed. With infection, all are elevated • WBCs (5,000-10,000 mm3) • Neutrophils (60-70%)- acute infection • Lymphocytes (20-40%)- chronic infection • Eosinophils (1-4%)- allergic reaction • Pathogen present in culture

  17. Patient Outcomes • Handwashing • Hygiene • Nutrition • Immunizations • Signs of infection • Symptoms of allergies

  18. Asepsis • Activities to prevent spread of infection • Medical asepsis- clean technique • Surgical asepsis- sterile technique

  19. Medical Asepsis • Hand hygiene • Carry linens away from your body • No linens on floor • Cover mouth when sneezing • Do not raise dust • Do not shake linens • Clean to dirty • Transmission precautioins

  20. Hand Hygiene

  21. CDC Guidelines • Soiled hands- Wash with soap and water • Not visibly soiled- alcohol based rub

  22. Personal Protective Equipment • Gloves • Gown • Mask • Protective Eyewear

  23. PPE

  24. Disposing of Contaminated Supplies

  25. OSHA Precautions • Standard Precautions

  26. OSHA Precautions • Airborne Precautions

  27. OSHA Precautions • Droplet Precautions

  28. OSHA Precautions • Contact Precautions

  29. Surgical Asepsis • Sterile can touch only sterile • Do not spill on a sterile field • Hold objects above waist • Do not reach over field • Do not turn back on field • Outer 1 inch is considered sterile • If in doubt, treat as contaminated

  30. Surgical Asepsis • Donning Sterile Gloves

  31. Surgical Asepsis • Opening Sterile Packages

  32. Surgical Asepsis • Sterile Procedures

  33. Nosocomial Infections • Hospital Acquired • Handwashing- best way to prevent nosocomial infections

  34. Antibiotic-Resistant Organisms • MRSA Methicillin Resistant Staphylococcus aureus VRE Vancomycin Resistant Enterococcus VISA- Vancomycin Intermediate Resistant Staphylococcus aureus
