Flashcards in Lecture 2 - Preparation of Surgical Packs and Team Deck (41)
How often should instruments be cleaned?
ASAP after each use
What does cleaning instruments remove?
Organic debris and inorganic salt that can affect sterilization
What type of water should be used to clean instruments and why?
Distilled or deionized; avoids excess salt, has neutral pH
What type of scrub brush should be used to clean insturments?
T/F: Instruments should not be soaked
What type of cleaner should be used for the instruments?
One specific for instruments
What is a part of regular instrument maintenance?
How should instruments be dried?
With a clean cloth in a timely manner
What are the 4 sterilization methods?
1. Steam (autoclave)
2. Hydrogen peroxide gas plasma
3. Ethylene oxide
4. Vaporized hydrogen peroxide
What is the most common method of sterilization and why is it used so often?
Inexpensive, easy to use, non-toxic, penetrates packs
What is a disadvantage of ateam autoclaving?
May damage heat labile items such as endoscopes and anesthesia tubes
What is the temp of autoclaves?
What are the 2 types of steam autoclaving?
Gravity displacement and pre-vacuum
What type of steam autoclaving is most common?
Under what principle does gravity displacement autoclaving work?
Air is heavier than steam, is passive
Under what principle does pre-vacuum autoclaving work?
Active movement of air out of the chamber
What temp/time does the ISU autoclave use?
121 degrees C for 30 min, 15 min dry time
What are chemical sterilization indicators?
Impregnated paper strips or tape change color when a certain temperature is met
T/F: Chemical sterilization indicators do not reflect duration of exposure and do not indicate sterility
What are biological sterilization indicators and how often should they be used?
Highly resistant, non-pathogenic, spore-forming on paper or in glass vial placed in autoclave;
Use once weekly to ensure effective sterilization process
How do biological sterilization indicators work?
After cycle is completed, indicator is cultured;
Any growth indicates failure of sterilization
Who/what is responsible for ensuring efficacy of sterilization in practice?
What are the contents of our surgical packs?
1 blue huck towel
20 4x4s - sponge count
1 paper patient drape
4 green huck towels
2 teri towels per gown
What is the purpose of pack preparation?
To allow penetration of sterilization agent and sterile handling of equipment prior to use
What are the steps of wrapping an instrument pack?
1. Wrap the pack in a clean huck towel
2. Place a pack wrap on a large clean surface
3. Fold the corner closest to you over the tray, fold in edge
4. Fold the right corner over the pack repeat on left
5. Turn around the pack and fold in the far corner, tucking it under the previous folds
6. Repeat with a second layer, apply chemical indicator tape, date, initial
What are the steps to folding/wrapping a gown?
1. Place a clean gown on a clean, flat surface, front facing up
2. Fold the sleeves toward the center of the gown
3. Fold the sides of the gown to the center midline (seams align)
4. Fold the gown in half longitudinally
5. Begin fanfolding the bottom of the gown to neck
6. Fold hand towel in half, fanfold similarly, dog ear
7. Wrap the gown with the towel on top in a double wrap
What is the ideal environment for pack storage?
Cool, dry and temp controlled environment
What is the shelf life of a pack dependent on?
type of materials used; consult autoclave manufacturer recommendations
When should you NOT use a pack?
If the seal is broken or the packaging is damaged
