3. INTRODUCTION The goal is to reduce health care-associated infections. In infection control chain explain the process how the Germs move to patients from hands, and from objects used for patient care. So in order to break the chain infection we have to understand the different Use of clean, aseptic or sterile technique to reduces the number of germs transferred and thus, reduces the risk of infection 4: Clean, Aseptic, Sterile Slide 3

4. Definition: Clean Technique 4: Clean, Aseptic, Sterile Slide 5

5. ASEPTIC TECHNIQUE is used for short invasive procedures. It involves: Antiseptic hand hygiene ( chlorhexidine) Sterile gloves Antiseptic (chlorhexidine ) on patient’s skin Use of clean, dedicated area Example: inserting a urinary catheter suctioning placing an IV cannula emptying a INTERCOSTAL DRAIN ICD drain

6. DEFINITION: STERILE TECHNIQUE Sterile technique is used for surgery or the preparation of sterile materials for multiple patients. It involves: Surgical hand rub with long acting antiseptic or hand scrubs with chlorhexidine gluconate or povidone  iodine  solutions  Hands dried with sterile towels Sterile field Sterile gown, mask Sterile gloves Sterile supplies Skin preparation

7. A dedicated room: Use during surgery and for invasive procedures with high rates of infection Examples: Any long invasive procedure like surgery in OR Placement of central lines Bulk preparation of IV fluids or medications

8. TO PREVENT Contamination Keep clean, dirty, and sterile items separate: Only put sterile items in a sterile field Change gloves and wash hands if going from a contaminated act to a aseptic or sterile act Time skin antisepsis and surgical hand hygiene with a clock The sterile field is considered sterile except for the 2.5 cm border So never place items right on the edge of the sterile field 4: Clean, Aseptic, Sterile Slide 9

9. PLANNING REDUCES ERRORS IN TECHNIQUES USE THE S.C.R.I.P.T. REMINDER TO PLAN S pace and work flow? C lean, aseptic, or sterile technique? R outine, aseptic or surgical hand hygiene? I nstruments and supplies? P ersonal protective equipment? T rash: sharps, infectious waste, radioactive waste, pathology or routine waste? 4: Clean, Aseptic, Sterile Slide 10

10. ASEPSIS AND ASEPTIC PRACTICES IN THE OPERATING ROOM PRINCIPLES Principle #1 Scrubbed persons function within a sterile field. 2 Principle #2 Sterile drapes are used to create a sterile field. 2,5 Principle #3 All items used within a sterile field must be sterile. 2,4 Principle #4 All items introduced onto a sterile field should be opened, dispensed, and transferred by methods that maintain sterility and integrity. 2,4  

11. PRINCIPLES OF ASEPTIC TECHNIQUE Principle #5 A sterile field should be maintained and monitored constantly. 2,5 Principle #6 All personnel moving within or around a sterile field should do so in a manner to maintain the sterile field. 2 Principle #7 Policies and procedures for maintaining a sterile field should be written, reviewed annually, and readily available within the practice setting. 2

12. PRINCIPLES OF ASEPTIC TECHNIQUE 8. The edge of anything that encloses sterile contents is not considered sterile. Never touch the rim of bottles/containers of sterile content. Consider the rim of bottles unsterile. Never touch equipment on rims of bottles. Before using the sterile content pour a little amount to clean the rim of its container. 9. Sterile persons keep within the sterile area. 10. Non-sterile persons keep away from sterile area.

13. PRINCIPLES OF ASEPTIC TECHNIQUE 11. Sterile persons keep contact with sterile area to a minimum. Although sterile persons are sterile still refrain from touching the sterile equipment to prevent still any contamination. 12. Moisture may cause contamination. Sweat is moisture and may cause contamination. Your armpit is one site so never place your hands under it or near it. 13. When bacteria cannot be eliminated from a field they must be kept to an irreducible minimum. 14. Destruction of integrity of microbial barriers result in contamination. Your sterile gloves' pack should never be folded to prevent crease and to prevent it from easily being torn and exposed

14. The goal of asepsis is to prevent the contamination of the open surgical wound by isolating the operative site from the surrounding nonsterile environment. 1  The surgical team accomplishes this by creating and maintaining the sterile field and by following aseptic principles aimed at preventing microorganisms from contaminating the surgical wound

15. Clean, aseptic and sterile Examples of procedures SCRIPT the procedure to clearly define what is expected and needed from all team members to reduce health care associated infections Principles of Aseptic technique 4: Clean, Aseptic, Sterile Slide 16
