Objectives: After 15-30 minutes of lecture, the students will be able to: differentiate medical from surgical asepsis, identify the different purpose of aseptic technique, enumerate at least 5 indications for aseptic technique , and enumerate the 13 principles of aseptic technique.
MEDICAL & SURGICAL ASEPSIS
Asepsis It is the absence of germs or microorganisms.
Types of Asepsis Medical Asepsis vs Surgical Asepsis
Comparison Medical Asepsis Surgical Asepsis Reduce the number and spread of microorganisms Destroys ALL microorganisms and their spores Clean technique Sterile technique Ex. Hand washing, Wearing hospital garments Ex. Gas sterilization, autoclaving
Aseptic Technique Used to help prevent or minimize contamination of wounds and other susceptible sites by organisms that could cause infection. Known as ‘Surgical asepsis’ Is employed during any procedure that bypasses the body’s natural defenses.
Aim of aseptic technique To protect the patient from infection and to prevent the spread of pathogens
Indications for the use of aseptic technique Suturing and care of surgical wounds Insertion of invasive devices, such as peripheral and central venous catheters (CVC) Insertion of urethral catheters and tracheostomy tubes
13 PRINCIPLES OF ASEPSIS
1. All items in a sterile field must be sterile . 13 PRINCIPLES OF ASEPSIS
2. Sterile persons touch ONLY sterile articles while UNSTERILE persons touch only unsterile articles. 13 PRINCIPLES OF ASEPSIS
13 PRINCIPLES OF ASEPSIS 3. If in doubt about the sterility of anything, CONSIDER it UNSTERILE!
13 PRINCIPLES OF ASEPSIS 4. Unsterile persons, avoid reaching over sterile field while sterile persons avoid leaning over unsterile area.
13 PRINCIPLES OF ASEPSIS 5. Tables are sterile only at table level.
13 PRINCIPLES OF ASEPSIS 6 . Gowns are considered sterile only from the waist- shoulder level and the sleeves.
13 PRINCIPLES OF ASEPSIS 7 . The edge of anything that encloses sterile contents is considered unsterile.
13 PRINCIPLES OF ASEPSIS 8 . Sterile persons keep within the sterile area. 9 . Non-sterile persons keep AWAY from sterile area.
13 PRINCIPLES OF ASEPSIS 10. Sterile persons keep contact with sterile area to a minimum.
13 PRINCIPLES OF ASEPSIS 11. Moisture may cause contamination.
13 PRINCIPLES OF ASEPSIS 12 . When bacteria cannot be eliminated from a field they must be kept to an irreducible minimum.
13 PRINCIPLES OF ASEPSIS 13. Destruction of integrity of microbial barriers result in contamination.
