Aseptic Non-Touch Technique - Background & Overview
|Reviewed by Guidelines Committee|
To ensure a standard, safe and efficient aseptic technique is used.
All nursing staff
Whenever an aseptic procedure is required, for example:
The table below indicates other documents and sources associated with this recommended best practice.
Sterile techniques are not achievable:
Aseptic Techniques are achievable:
For an infection to occur there must be contamination by a sufficient number
of virulent, pathogenic organisms. Therefore, a technique that prevents such a
level of pathogenic organisms from entering a patient is a safe technique. Such
a technique is most accurately termed an ‘aseptic technique’, as the word
asepsis means, ‘freedom from infection or infectious (pathogenic) material’.
Non-Touch Technique is part of asepsis
A non-touch-techniqu i.e. being able to identify the ‘key-parts’ and not touching them either directly or indirectly is perhaps the single most important component of achieving asepsis.
Aseptic Non-Touch Technique (ANTT) is a technique that maintains asepsis and
is non-touch in nature.
In a logical order, staff identifies and protects the key-parts of any procedure, performs effective hand hygiene, institutes a non-touch technique, and wears the appropriate standard precautions (generally non-sterile gloves).
The critical components are:
Note: use latex free gloves for patients with or at risk of latex allergy.
To prevent accidental contamination, hair should be tied back, and lanyards removed or tucked in prior to commencing an aseptic non-touch technique.
An antiseptic 30 sec handwash with 4% chlorhexidine or handrub with alcohol
based product as described by Infection Control.
No artificial nails or chipped nail polish are permitted due to risk of microbial contamination.
A single banded ring only is permitted.
Key parts are defined as those parts which if contaminated by infectious
material increase the risk of infection.
In IV therapy, key parts are usually parts of equipment which come into direct contact with the liquid infusion eg. Needles, syringe tips, IV line connections, exposed central line lumens, etc.
If it is impossible to perform a procedure without touching the key-parts
then sterile gloves should be worn.
Sterile gloves may also be worn for particularly difficult procedures or those that take a significant amount of time as the potential for accidental direct/indirect contamination is increased.
Wipe down trolley top or surface used with 70% Alcohol Surface disinfecting
If body fluid present, clean the surface with soap and water and then a 70% alcohol wipe.
Clean key parts with 2% chlorhexidine and 70% alcohol wipes or sterile gauze swabs soaked in 2% chlorhexidine and 10% alcohol and allow to dry for 30 seconds.
