- Persons who are sterile touch only sterile articles; persons who are not sterile touch only unsterile articles.
- Sterile persons avoid leaning over an unsterile area; non-sterile persons avoid reaching over a sterile field.
When must you follow the principles of Antt?
(Rowley, 2000). contact with susceptible or sterile body sites during clinical procedures. ANTT should be undertaken when performing a medical aseptic procedure i.e. cannulation, venepuncture, IV medication, wound care, urinary catheterisation and central and peripheral line management.What are key parts in Antt?
Key-Parts are the critical parts of the procedure equipment that if contaminated are most likely to cause infection. E.g. needles, syringe tips, intravenous line connections, exposed lumens of catheters, tops of ampoules. infection precautions such as hand cleaning and glove usage etc.
When is Antt required?Surgical ANTT is needed when procedures are technically complex, last approximately >20 minutes, involve large open key sites, and large or numerous key parts.
Article first time published onWhat is non touch technique?
Non touch technique is a method of changing a dressing without directly touching the wound or any other surface that might come into contact with the wound. It is essential to ensure that hands, even though they have been washed, do not contaminate the sterile equipment or the patient.
What is the difference between sterile and aseptic?

What are valid safeguards in Antt?
ANTT is based on a set of principles and safeguards that focus primarily on two fundamental concepts: Key-Parts protection: the critical parts of the procedure equipment that if contaminated are most likely to cause infection; Key-Sites protection: open wounds and medical device access sites.
Which three of the following are valid safeguards Antt?
decontaminate and protect: surgical hand scrub. use of sterilised gloves. a mask. wear a sterilised gown if full barrier protection is required.
Who invented Antt?
The ANTT® Clinical Practice Framework (CPF) was originated by Rowley in the mid-1990s (Rowley, 2001) and is defined by The National Institute for Health and Care Excellence (NICE) as, ‘a specific type of aseptic technique with a unique theory and practice framework’ (NICE, 2012).
What is Aseptic Non Touch Technique Antt?

What is the difference between the suffix cide and suffix static?
Physical or chemical methods to control microbial growth that result in death of the microbe are indicated by the suffixes -cide or -cidal (e.g., as with bactericides, viricides, and fungicides), whereas those that inhibit microbial growth are indicated by the suffixes -stat or-static (e.g., bacteriostatic, fungistatic …
