Updated on April 06, 2026
Aseptic technique is used during clinical procedures to identify and prevent microbial contamination of aseptic parts and sites by ensuring that they are not touched either directly or indirectly. A widely used method of aseptic technique is known as Aseptic Non Touch Technique (ANTT®).
What are the 4 key principles of Antt?
- The underlying principles of ANTT are:
- Always wash hands effectively;
- Never contaminate key parts;
- Touch non-key parts with confidence;
- Take appropriate infective precautions.
What is aseptic technique in simple words?
Aseptic technique is a collection of medical practices and procedures that helps protect patients from dangerous germs. Bacteria, viruses, and microorganisms are everywhere, so using aseptic technique can help keep important equipment from being contaminated.
How is the non touch technique works?
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.When do you use Antt?
ANTT must be applied for any invasive procedure, for example wound care, urinary catheterisation, drug administration. In IV therapy, key parts are usually those which come into direct contact with the liquid infusion e.g. needles, syringe tips, exposed central line lumens.
What is Antt NHS?
ANTT is the practice of avoiding contamination by avoiding unnecessary contact with key sites of the patient’s body and key parts of equipment. Only staff trained and assessed as competent in ANTT should undertake aseptic procedures.
What is a key part in Antt?
Key parts are the critical parts of clinical equipment that come into direct or indirect contact with any liquid infusion, key sites and any active key parts connected to the patient (Fig 2). If contaminated they present a significantly high risk of infection. 4. Asepsis is achieved with standard ANTT or surgical ANTT.
What is Aseptic Non Touch Technique Antt?
Aseptic technique is used during clinical procedures to identify and prevent microbial contamination of aseptic parts and sites by ensuring that they are not touched either directly or indirectly. A widely used method of aseptic technique is known as Aseptic Non Touch Technique (ANTT®).Is Antt evidence based?
NICE suggests ANTT® may represent a possible framework for establishing aseptic guidance (NICE, 2012). This study provides evidence for the sustainability of a competency-based quality standard for aseptic technique.
What is the difference between aseptic and sterile technique?Aseptic means something has been made contamination-free, that it will not reproduce or create any kind of harmful living microorganisms (bacteria, viruses and others). Sterile describes a product that is entirely free of all germs.

Where is aseptic technique used?
Aseptic technique means using practices and procedures to prevent contamination from pathogens. It involves applying the strictest rules to minimize the risk of infection. Healthcare workers use aseptic technique in surgery rooms, clinics, outpatient care centers, and other health care settings.
How is Antt different from a surgical sterile procedure?
In practice, the main difference between Standard and Surgical-ANTT is the type and management of aseptic field(s) depending on the number of Key- Parts and Key-Sites that require protection.
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.
What are key parts and key sites?
Key Parts are the most critical parts of the procedural equipment, that if contaminated are likely to cause infection. Key Sites are medical device access sites or open wounds. An Aseptic Field is a controlled workspace used to promote asepsis during a clinical procedure.
What is a key part in aseptic technique?
Key Parts – Key parts are the sterile components of equipment used during a procedure. Examples: bungs, needle hubs, syringe tips, dressing packs etc. Key Sites – Key sites include any non-intact skin and insertion or access sites for medical devices connected to the patient.
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.
What does Antt stand for?
Aseptic Non Touch Technique or ANTT® is a tool used to prevent infections in healthcare settings.
Do you need to wear gloves if the Antt guideline is being followed and all main principles are being observed?
Sterile gloves are not always required to undertake ANTT as long as the key parts are not touched by anything that is not sterile. If the procedure is complex or the patient is immunocompromised, sterile gloves must be worn.
Why is it important to use Antt to change a dress?
When applying or changing dressings, an aseptic technique is used in order to avoid introducing infections into a wound. Even if a wound is already infected, an aseptic technique should be used as it is important that no further infection is introduced.
Which antiseptics are commonly used for dressing?
Commonly used antiseptics include povidone-iodine, boracic lint dressings or historically castor oil. Antibiotics are also often used with dressings to prevent bacterial infection.
Does sterile mean no viruses?
While sterile means the complete absence of bacteria, viruses, and fungi along with spores, it doesn’t distinguish between specific pathogens. … A sterilization technique aims to rid an environment of all living microorganisms.
What does non aseptic mean?
The non-aseptic lab space is where the product or reagent is exposed to the Class 100,000 or a clean unclassified environment. … These are the areas where the product is formulated and manually filled into the proper container.
Does sterile mean clean?
While clean means free from marks and stains, sterile goes even further and is free from bacteria or microorganisms. … Sterile environments use antiseptic cleaners, are those working in the industry are typically wearing gowns, gloves, masks and are covered from head to toe.
Why is Antt important in nursing?
ANTT is a core nursing and medical skill that defines the infection prevention and control methods and precautions necessary during invasive clinical procedures to prevent the transfer of microorganisms to ‘key’ or sterile body sites from healthcare professionals, procedure equipment or the immediate environment to a …
What is the purpose of sub culturing?
Sub-culturing is done to maintain culture in its active form (prolonging life and/or increase the number of cells) for varied applications. Microbial growth is defined as increase in number and/or biomass. All microorganisms require food, oxygen, moisture, and space for growth.
How do you sterilize wire loop?
The inoculating loop is sterilised by passing it at an angle through the flame of a gas burner until the entire length of the wire becomes orange from the heat. In this way all contaminants on the wire are incinerated. Never lay the loop down once it is sterilised, or it may again become contaminated.
