ACEPTIC TECHNIQUE Flashcards
What is ASEPSIS?
freedom from infectious material.
What is Medical Asepsis?
reduction in the number of microorganisms. The single most important component is frequent hand washing. i.e. Hand washing, and chemical disinfectants.
What is Surgical Aspesis?
Microorganisms have been completely removed or destroyed from the equipment and environment by means of a sterilization process.
Which Asepsis technique is practiced and which is required?
Medical Asepsis is always practiced,
Surgical asepsis is required for invasive procedures
What are some Various METHODS OF ASEPTIC TECHNIQUES?
Sterile Draping
Sterile Packs
Sterile Scrubbing
Sterile Gowning and Sterile Gloving
Sterile Procedures
What is a Sterile field?
A Sterile Field means that the area is free of all microorganisms.
How is the Sterile field established?
The field is established using Sterile drapes.
What is STERILE DRAPPING?
A Sterile Drape is a sterile packaged drop cloth that isolates an area from contamination.
What does STERILE DRAPE COVER?
A sterile drape covers a surface.
What should we check for on a Sterile drape package?
Check expiration date on package, never use anything past the expiration date.
Can we use an unseal sterile drape package?
Only use sealed packages.
How do we open STERILE DRAP PACKAGES?
Open sterile packages adhering to sterile technique.
Packages are opened away from the person opening the package.
How many inches away are STERILE PACKAGES GENTLY DROPPED ONTO THE STERILE FIELD?
6 INCHES ABOVE THE FIELD AT A SLIGHT ANGLE
Sterile items are gently dropped onto the sterile field from about 6 inches above the field at a slight angle.
If a STERILE DRAPE BECOMES WET, IS IT CONSIDERED STERILE STILL OR UNSTERILE?
If a sterile drape becomes wet for any reason it is considered unsterile
Can an unsterile package wrapping touch the sterile field?
Unsterile package wrappings should never touch the sterile field.
What are STERILE PACKS?
Packages that are commercially prepared for a specific procedure that will contain the necessary sterile items.
What will the STERILE packs contain?
Packages may include items that will be routinely used in a specific procedure: gauze, syringes, forceps, basins, etc.
What are 3 types of STERILE PACKS?
OR sterile packs
Minor procedure packs
Special procedure packs
HOW DO WE OPEN A STERILE PACK?
- To unwrap s sterile pack hold pack in the left hand. (Vice Versa)
- Unfold one corner of the wrap at a time, secure each corner in the palm of the left hand.
3.Hold the final corner with the right hand, hand should be completely covered by the warp.
4.When the pack is fully exposed and all corners secured, gently set the pack onto the sterile field, being careful not to allow your hand or arm to reach across the sterile field.
What is SURGICAL SCRUBBING?
Surgical Scrubbing is the thorough cleaning of the hands and forearms before sterile gloves are put on
WHAT ARE 2 TYPES OF SURGICAL SCRUBS?
-Numbered stroke method
- Timed Scrub
A minimum of 5 minutes
-All surgical scrubs are of a 5 minute duration with 2 ½ minutes of time spent on each hand and arm.
SURGICAL SCRUB- SCRUB FOR 5 MINUTES MINIMUM
A surgical scrub anteseptic solution are?
*Currently, a surgical scrub with 2% chlorhexidine gluconate or
7.5% povidone-iodine is performed before each procedure
For the surgical SCRUBBING TECHNIQUE, WHAT SHOULD WE LOOK FOR?
-Hands should be inspected for breaks in the skin
-No open wounds
-Mask and surgical cap must be put on before scrubbing
-All surgical scrubs are of a 5 minute duration with 2 ½ minutes of time spent on each hand and arm.
Why should we inspect the hands?
-Hands should be inspected for breaks in the skin
- SHOULD BE NO OPEN WOUNDS
WHAT SHOULD BE PUTTED ON FIRST BEFORE SCRUBBING?
Mask and surgical cap must be put on before scrubbing
WE use liquid or foam soaps for surgical scrubbing such as?
- Liquid or foam soaps. These are the most common products for surgical scrubs and are used in conjunction with water and dry scrub brushes or sponges.
The most common antimicrobial agents in these products are CHG (chlorhexidine gluconate), iodophor, or PCMX (parachlorometaxylenol).
These agents are very drying and with repeated scrubbing with the scrub brush can cause skin damage.
What Types of brushes/sponge are used?
- Impregnated scrub brushes/sponges.
(Scrub brushes/sponges are preloaded with CHG, iodophor, or PCMX and are water-aided products.)
- Brush-free surgical scrub.
(These products use an antimicrobial agent and water but no scrub brush)
Non-Scrubbed personnel follow the aseptic techniques during surgical procedures:
Non-scrubbed personnel (runners):
Remove rings, watches and bracelets and other jewelry
Wear long sleeved clean scrub suit
Wear clean surgical cap or hood that covers hair
Wear clean closed shoes that will provide protection from fluids and dropped items
Wear masks covering mouth and nose, when open sterile items and equipment are present
Stay at the periphery of the OT, keeping a distance away from sterile areas
Unsterile Personnels should?
Stay at the periphery of the OT, keeping a distance away from sterile areas
What is the SURGICAL SCRUB PROCEDURE?
Make sure all cleaning supplies are available.
(scrub brush, antiseptic soap, nail cleaners)
Remove all jewelry, including watches.
Wash hands and arms with antiseptic soap.
Scrub the sides of each finger, between the fingers, and the back and front if the hand for 3 mins.
Scrub the arm with the hands higher than the elbows.
Each side of the arm is washed to 3 inches above the elbow for 1 minute.
Repeat the process for the other hand and arm.
The hands remain above the elbows at all times.
Dry the hands with sterile towels.
How do you wash/scrub YOUR ARM?
Scrub the arm with the hands higher than the elbows.
Each side of the arm is washed to 3 inches above the elbow for 1 minute.
Where should the hands be ?
The hands remain above the elbows at all times.
How should we perform the SURGICAL SCRUB?
-PALM TO PALM
- FINGERS INTERLOCKED
-ROTATIONAL RUBBING OF RIGHT TUMB CLASP ON OTHER
The purposes of the surgical hand scrub are?
(1) to remove debris and transient microorganisms from the hands, nails, and forearms
(2) to reduce the resident microbial count to a minimum; and
(3) to inhibit the rapid rebound growth of microorganisms.
When is Surgical Gowning and Gloving done?
Done after surgical scrubbing.
What are two methods of Gowning?
- Self-Gowning
- Gowning Another
What are 2 methods of Gloving?
- Self-Gloving
- Gloving Another
( 2 PERSON GLOVING)
What are 2 types of SELF GLOVING METHOD?
- OPEN GLOVE METHOD
- CLOSED GLOVE METHOD
What does STERILE GOWNING AND GLOVING FOCUS ON?
Sterile gowning and gloving focuses on surgical asepsis
How is Gowning and Gloving in SURGICAL ASEPSIS DIFFER FROM ISOLATION GOWNING AND GLOVING?
Sterile gowning and gloving focuses on Surgical asepsis
DIFFERS:
Isolation gowning and gloving which follows Medical asepsis techniques.
What are Sterile Procedures?
Radiographers must adhere to Principles of Basic Sterile Technique
Some Sterile Techniques are?
Only sterile items are used in sterile fields.
If in doubt about sterility of an object, consider it unsterile.
An unsterile object should be removed, covered or replaced.
As sterile field must be continually monitored to be considered sterile.
Create sterile fields as close to the time of use as possible.
Sterile persons should avoid unsterile areas.
What Parts that are sterile?
The front of the gown, the sleeves and anything above the waist up.
What parts are UNSTERILE?
The back of the gown and the area below the waist are considered unsterile.
below the level of the table or the level of the waist, the undersurface of the drape, is considered unsterile. Any item below this level is considered contaminated.
What parts of the glove should be considered unsterile when handing a sterile glove with an unsterile hand?
-UNSTERILE IS INSIDE OF THE CUFF
-Sterile gloves must be kept in sight and above waist level
A radiographer who is assisting with a sterile procedure but is not gloved and gowned:
May not have contact with the sterile field or anyone who is scrubbed in
When putting on gloves for a procedure, which of the following should occur first?
Wash hands
After a radiographer is gowned and gloved for a procedure, hands may not be placed:
Under the arms or on the sides or back of the
gown
WHERE SHOULD STERILE GLOVES BE KEPT?
Sterile gloves must be kept in sight and above waist level
STERILE ITEMS MUST BE KEPT DRY?
Sterile materials must be kept dry. Moisture permits contamination. Packages that become wet must be re-sterilized or discarded
HOW SHOULD PERSONS I STERILE GOWN AND GLOVE PASS EACH OTHER?
back to back
What can a STERILE PERSON TOUCH?
A sterile person may touch only what is sterile.
What must a UNSTERILE PERSON not do?
Unsterile persons cannot reach above or over a sterile field
What should we do if a solution soaks through a sterile field?
If a solution soaks through a sterile field to a non-sterile field, the wet area may be redraped.
What is the STERILE FIELD MADE UP OF?
Includes the patient, table, anything covered with a sterile drape and personnel wearing sterile attire.
Respect the “sterile corridor” which is the area in the OR between the patient drape and the instrument area.
Never pass anything over a sterile corridor, including the instrument table or pass through the sterile corridor.
What exactly is the STERILE FIELD?
The sterile field is any area prepared to receive sterile items or equipment.
