1 Nursing Skills Sterile Technique & Dressings

2 Terminology Asepsis= absence of germs Surgical asepsis or sterile technique= practices aimed at eliminating all germs Medical asepsis or clean technique=practices aimed at controlling & reducing # of germs Sterilization= process where all forms of germs and spores are destroyed

3 Clean vs. Sterile Technique Clean technique –Use clean gloves –Use for routine pt care –Involves hand washing –Part of BSI -prevent infection spread –Used in home settings for procedures Sterile technique –Use sterile gloves –Use sterile supplies –Procedures involving sterile body cavities –Involves hand washing –Used in hospital & ECF to prevent nosocomial infections

4 Basic Ideas of Sterility Germs are not visible without a microscope Germs may be transferred directly or indirectly The body has various defensive barriers Cleanse from least contaminated to most contaminated Germs require organic food and moisture to grow

5 Principles of Sterile Technique Principle #1 –An article is accepted as sterile only if it is completely enclosed in a dry, intact, wrapper and marked sterile Principle #2 –Wrapped sterile articles have a limited shelf life

6 Sterile Technique (cont.) Principle #3 –Sterile supplies are contaminated if their wrappers are torn or wet. Moisture causes contamination by wicking or capillary action Principle #4 –The outside and edges of wrapper containing sterile articles are considered unsterile to 1 (inch). Use table edge.

8 Sterile Technique (cont) Principle #5 –Skin cant be sterilized so contact b/t skin and sterile surfaces cause contamination Principle #6 –Only articles above waist and table level are considered sterile

9 Sterile Technique (cont) Principle #7 –Organisms are pulled downward by gravity Principle #8 –Organisms are carried by air currents –Prolonged air exposure is bad –Do not talk or sneeze over field unless have to

10 Sterile Technique (cont) Principle #9 –An article or area is either sterile or non-sterile, it cannot be both (If in doubt it is not sterile) Principle #10 –It is only sterile if you can see it –Do not turn your back to a sterile field –Keep it in line of your vision

11 Opening a Sterile Field or package –Make sure surface is clean & dry –Open away from you first –Open sides next –Toward you last –Only touch outer 1 border and outside –If is a package open away from you

12 Establishing a Sterile Field Adding supplies to sterile field –Open well above sterile field- do not tear –Do not touch sterile object –Drop on field within 1 border –Try not to touch other items c new object

13 Adding Sterile Solution to a Bowl If old bottle check expiration (usually about 24 hrs after opened) Open bottle carefully and put cap face down (this prevents contamination) Lip liquid to remove germs Pour slowly to prevent splashing Pour with label in palm of your hand

14 Open Sterile Glove Application Wash hands & proper size Peel open & place on clean flat surface Open up gloves (do not allow to close- fold in half) Grab #1 glove by outside of cuff Slip on glove away from other objects Grab #2 glove by inside cuff with sterile hand Now adjust both

16 Common Sources of Contamination HC members active infections Poor sterile technique Most contaminations are accidental Contaminations not seen by team Procedure is very long Unsterile person enters sterile area Mask worn improperly or never changed Excessive debris in air from poor air circulation Clients or visitors (they dont go to nursing school)
