B5.4 Examples of How to Perform Aseptic Non-Touch Technique
B5.4.1 ANTT for peripheral and central access intravenous therapy
Typically, IV maintenance procedures will be assessed as requiring Standard ANTT with the employment of a main general aseptic field and
critical micro aseptic fields.

1
Perform hand hygiene
This will break any potential transmission of infection from the clinical ward environment to the clean preparation area/room. Effective
hand hygiene is vital to reduce the risk of contaminating key parts/sites
2
Use a clean tray
Such a tray provides a sufficiently large, robust and controlled working area. Reprocess re-usable trays according to local policy
3
While the tray is drying, gather equipment
Hands are contaminated when gathering equipment from storage cupboards etc. It’s important therefore to gather all equipment before
performing hand hygiene at Step 4. Gathering equipment at this point also allows the tray to dry properly and saves a little time
4
Perform hand hygiene
This occurs immediately before assembly of equipment and the preparation of drugs. This way, hands are optimally clean prior to glove
application and non-touch technique key part manipulation
5
Apply non-sterile gloves (use sterile gloves if you must touch key parts)

Apply non-sterile gloves (use sterile gloves if you must touch key parts)
Primarily, gloves are worn to protect the user from drug exposure and blood products. All peripheral and central access IV procedures
should be performed without touching key parts. Therefore, non-sterile gloves will nearly always be the logical and efficient glove
choice. In the event the healthcare worker unknowingly touches a key part, non-sterile gloves also act as a safety net as they are typically
cleaner than skin
6
Assemble equipment and prepare medications — protect key parts using non-touch-technique
A non-touch technique is the most important component of aseptic practice because a key part cannot be contaminated directly if it is
not touched. Key parts should be protected throughout the procedure when they are not in use. This can be achieved by using sterilised
IV bungs or the inside of syringe packets. Both systems provide critical micro aseptic fields around the key part.

User assessment:
If gloves become contaminated – decontaminate hands and re-glove
This is necessary when it is not possible to proceed from preparation to administration without contaminating gloved hands (e.g. due
to prepping a patient).
If gloves remain uncontaminated between steps 6 and 7 proceed directly to step 7
Where it is possible to retain the asepsis of gloved hands between preparation and administration, the user does not need to
decontaminate hands between administration and preparation. This will promote compliance and save time
8
Clean key parts
2% chlorehixidine/70% alcohol wipes is the application of choice (Pratt et al 2007). In addition, the benefit of using friction and allowing
key parts to dry has been demonstrated by Kaler and Chinn (2007).
Method:
A large 2% chlorhexidine and 70% alcohol wipe should be fully unfolded to provide a suitable working surface area.
One side of the wipe should be exposed to the user’s gloved hand, the other side should be introduced to the hub (non-touch technique).
The port tip should be thoroughly wiped hard for 5 seconds — to create friction.
This should be repeated 4 times using different parts of the tissue (to remove dirt from the tip). After cleaning the hub clean the sides of
the port and line, working away from the port tip.
Allowing the hub to air dry promotes asepsis.
This technique provides the required level of friction. Using different parts of the wipe ensures any dirt is transferred from the hub to the
wipe. The hub must dry before use otherwise it won’t be aseptic (if organisms have remained, a wet tip will facilitate their transportation
into the patient on injection)
9
Administer medication using non-touch technique
Key parts cannot be contaminated by contact if they are not touched. A non-touch technique should therefore be used even if the user is
wearing sterile gloves (because once sterile gloves are open to air they are no longer sterile, and can also be inadvertently contaminated
by touch). If necessary, a small sterilised towel can be placed under a patient’s line to promote safe handling
10 Dispose of sharps and equipment then dispose of gloves
Sharps are best disposed of at the bedside if possible (on the basis that the quicker they are disposed of the less chance there is of an
accident)
11 Clean tray
Re-usable trays are reprocessed at the end of the procedure to prevent cross infection between patients and staff. Trays are reprocessed
according to local policy
12 Perform hand hygiene
It is essential that the post-procedure hand hygiene is performed immediately after glove removal i.e. before contact with the
environment (because gloves encourage the hands to sweat-out organisms from the skin).

B5.4.2 Aseptic non-touch technique for wound care
Wound care procedures are highly variable. Typically, a critical main aseptic field is employed and practice is dictated accordingly.

1 With clean hands clean trolley surfaces
Clean surface according to local policy to reduce the risk of aseptic field contamination.
2 Gather dressing pack and equipment, place on bottom shelf
Hands are contaminated when gathering equipment from storage cupboards etc. It’s important therefore to gather all equipment before
the next hanf hygiene. Gathering equipment at this point also allows the trolley to dry properly and saves a little time.
3 Perform hand hygiene
This occurs immediately before assembly of the aseptic field drape and equipment etc in order to promote asepsis.
4 Open pack, place drape on top shelf and position waste bag
5 Assemble equipment and position onto top shelf, protecting key parts
6 Apply non-sterile gloves
Non-sterile gloves are indicated because Steps 7 and 8 do not involve the touching of key sites or key parts.
7 Position a paper towel or drape under the wound
This will promote asepsis and help protect the surrounding environment from contamination.
8 Remove dressing, expose wound and dispose of dressing into waste bag
Disposing of the dressing here limits the movement of contaminated waste, helping to protect the wider clinical or community
environment.
9 Perform hand hygiene
Steps 7 and 8 are ‘dirty’ procedures and hand hygiene will promote asepsis.
10 Apply sterile gloves
Although not essential for some small, minor dressings, sterile gloves at this stage will help promote asepsis of the wound. NB: Sterile
gloves are essential at this stage if the wound requires touching directly with gloved hands.
11 Clean wound using non-touch technique
A non-touch technique will help protect the wound from colonisation or infection.
12 Dress wound using non-touch technique
A non-touch technique will help protect the wound from colonisation or infection.
13 Dispose of equipment, waste and gloves
Folding the used equipment and waste into the aseptic field drape and disposing it in the attached waste bag will minimise the movement
of waste and protect the wider working environment.
14 Clean trolley surfaces
Cleaning according to local policy will prevent cross infection.
15 Perform hand hygiene
This will help break any chain of potential cross infection.
