|
aseptic technique |
refers to the way ew handle the clean/sterile environment with regards to sterility |
|
|
asepsis |
the practice of rendering the environment free from disease producing pathogens |
|
|
surgical asepsis |
rendering the operative area as free from microbial contamination as possible |
|
|
sterile |
completely free from living organisms, including the spores |
|
|
transition area |
enter in street clothes and exit into area requiring scrubs |
|
|
unrestricted area |
central point where patients and staff enter street clothes are permitted traffic not limited in this area, although the entrance to the surgical suite is restricted to authorized personnel only |
|
|
unrestricted area examples (6) |
hall leading to practice sinks locker rooms office pre op holding area staff lounge waiting room |
|
|
what happens in the unrestricted area? |
no sterile activity tours pass, patient admitted, trash, patient discharged, street clothes worn then change into scrubs |
|
|
semi restricted |
support areas of the surgical suite traffic limited to authorized personnel all personnel required to wear scrub suits, hat, shoe covers face mask, eye wear, gloves only if cleaning instruments no sterile activity |
|
|
semi restricted examples |
inside corridor dirty utility room --> storage area for cleaning supplies + instrument decontamination clean utility room --> storage area for clean and sterile supplies |
|
|
restricted area |
sterile activity! - strictest area OR, clean core, scrub room scrubs, hats, shoe covers, face masks required eyewear required if scrubbing in authorized personnel only |
|
|
restricted area examples (3) |
scrub rooms OR scrubs, hats, shoe covers, face mask, eyewear if scrubbing |
|
|
what should you wear in the semi-restricted and restricted areas of the surgical suite? |
OR attire: surgical attire intended for use only within the surgical suite minimizes contamination from entering the OR |
|
|
examples of OR attire (6) |
1) clean scrubs 2) clean hat 3) clean shoe covers (over serviceable shoes) 4) no undershirts 5) no jewelry 6) no nail polish, acrylic nails, nails must be short --> now they want you to wear warm up jackets if you're not scrubbing in b/c they don't want any bare arms at all |
|
|
who are the sterile members of the surgical team? (4) |
1) surgeon 2) resident 3) 1st assist (4th year student extern) 4) 2nd assist (3rd year student scrubbed in) |
|
|
who are the non-sterile members of the surgical team? (4) |
1) anesthesiologist 2) nurse monitor for local cases only 3) circulator: these members act in a sterile manner to preserve sterility 4) patient |
|
|
recommended practice 1 |
all items within a sterile field must be sterile |
|
|
circulator |
(non sterile person) inspects the integrity of the drapes, gowns, instruments, and sterile back packs, before and during surgical cases |
|
|
how to achieve sterility |
autoclaving instruments - steam under pressure - regular cycle: - time: 30 minutes - pressure: 10-20 lbs - temperature: 250-270 degrees F, depending on the autoclave |
|
|
maintaining sterility |
shelf life- event related rather than date related |
|
|
shelf life |
length of time the item remains sterile depends on the occurrence of a contaminating event --Acommercially prepared item contains an expiration date- that date should behonored even if the facility has adopted an event-related system-unless therehas been a contaminating event |
|
|
recommended practice 2 |
the edges of sterile packages are not sterile once the package is open --> all items introduced onto a sterile field should be opened, dispensed, and transferred by methods that maintain sterility and integrity |
|
|
how can you assure recommended practice 2? |
an instrument may be used as an extension of a persons hand to assure a safety margin between fields |
|
|
containers holding sterile solutions are never sterile? |
T- must pour high and from a safe distance once the lid is off, only the contents are sterile. so when you pour liquids, fluid is poured onto the sterile basin |
|
|
recommended practice 3 |
gowns are sterile chest to table level in the front, including the sleeves to 2 inches above the elbow |
|
|
T/F- axilla, neckline, and back are sterile |
F: not sterile |
|
|
T/F- if standing away from a table, gowns are sterile chest to waist level in the front |
T |
|
|
gowns |
single use gowns are removed before leaving the OR to avoid contaminating the suite - gowns should provide appropriate barriers to microorganisms, particulate matter, and fluids |
|
|
recommended practice 4 |
tables are considered sterile at table-top level only - any item extending beyond the sterile boundary is considered contaminated and is not brought back into the sterile field |
|
|
recommended practice 5 |
movement is sterile to sterile unsterile to unsterile only -- sterile people cross each other front to back, or back to back -- all members, sterile and non sterile, must be aware when movement occurs to avoid contamination |
|
|
how do non scrubbed team members move in the OR? |
move from unsterile to unsterile and they maintain a 2 feet distance from any sterile field non scrubbed members are never permitted to walk between a sterile member and their sterile field |
|
|
recommended practice 6 |
movement and air currents within and around a sterile field must be minimal to avoid contamination - patterns of movement are adhered to rigidly during a surgical procedure |
|
|
recommended practice 7 |
contamination occurs whenever a bacterial barrier is violated - perforations in a barrier provide portals of entry and exit for microorganisms, blood, and other potentially infectious bodily fluids |
|
|
recommended practice 8 |
if in doubt regarding an item's sterility, consider it unsterile (fluids, integrity of package, expiration dates, gloves) |
|
|
surgical conscience |
every surgical team member, sterile or non sterile, whether witnessed or not, will point out known or suspected violations of sterile techniques and initiate corrective action - if someone tells you you did something unsterile, then you did. even if you disagree- don't take the risk |
