3 What is Aseptic technique? Aseptic technique aims to prevent pathogenic organisms, in sufficient quantity to cause infection, from being introduced to susceptible sites by hands, surfaces and equipment. It protects patients during invasive clinical procedures by utilizing infection prevention measures that minimize the presence of micro-organisms. Aseptic technique is a framework for aseptic practice. In aseptic technique, asepsis is ensured by identifying and then protecting key parts and key sites from contamination. This is achieved by correct: 1. hand hygiene, 2. non touch technique, 3. appropriate aseptic field 4. using new sterilised equipment and or 5. cleaning existing key parts to a standard that renders them aseptic prior to use. Whilst the principles of aseptic technique remain the same, the level of practice will change according to the risk identified using a standard aseptic technique risk assessment. The standard risk assessment involves assessment of technical difficulty and staff competence in maintaining asepsis. This self-directed learning package has been developed to provide all clinical staff with knowledge in aseptic technique in accordance with the Australian Guidelines for the Prevention and Control of Infection in Healthcare (2010). Core infection control components 1. Key parts and key sites identification and protection - key parts must be identified and protected at all times. Aseptic key parts must only come into contact with other aseptic key parts and / or key sites. 2. Hand hygiene Effective hand hygiene is an essential part of aseptic technique. In standard aseptic technique hand hygiene should be performed using neutral ph soap and running water or alcohol based hand rub. A surgical hand scrub is required for surgical aseptic technique. It is known that hand hygiene is not always performed correctly thus identifying key parts and not touching them is vital in maintaining asepsis. 3. Glove use if it is necessary to touch key parts or key sites directly, sterile gloves are used to minimize risk of contamination, body fluid exposure and / or exposure to any drugs that may be administered during the procedure. For example during IV cannulation, if you have swabbed the vein and need to repalpate you need to wear sterile gloves. 4. Aseptic fields aseptic fields are important in providing a controlled aseptic working space to help maintain integrity of the asepsis during clinical procedures. Size of the aseptic field will be dependent upon the complexity of the procedure to be performed. There are 3 types of aseptic fields > Critical aseptic fields are used when key parts and or key sites (usually due to their size or number), cannot be easily protected at all times with covers and caps, or handled at all times by non-touch technique. The critical aseptic field eg. a

4 dressing tray or surgical sterile drape, must be managed as a key part. This means that only sterile equipment may come into contact with it. Critical aseptic fields require the use of sterile gloves and often, full barrier precautions. > Examples of procedures requiring a critical aseptic field are CVC insertion and complex wound care. Critical aseptic fields are used in the Operating Theatre (see Appendix 1). > Critical micro aseptic fields involve covering or protecting key parts with syringe caps, sheaths, covers or packaging. The inside of caps and covers is sterile and provides optimum aseptic field for key parts. An example is an intramuscular needle. It is protected by the cap which ensures the needle, which is the key part, remains sterile and when utilising non touch technique the aseptic field is maintained (see Appendix 1). > General aseptic fields are used for standard aseptic technique when key parts can be easily and optimally protected. The main general aseptic field does not have to be managed as a key part and is essentially promoting rather than ensuring asepsis. An example is administering IV antibiotics. The key parts - the syringe tip and drawing up needle are easily protected by packaging, caps and non-touch technique. Therefore, a clean area is adequate as the key parts are protected using these critical micro aseptic fields. 5. Standard Aseptic technique > Typically short duration procedures (less than 20 minutes) > Technically simple procedures > Involve relatively few and small key sites and key parts > Requires a main general aseptic field and non-sterile gloves > Use of critical micro aseptic fields and non-touch technique is essential to protect key parts and key sites Examples include, any break/access to the sterile intravenous line/device such as changing lines, administrating drugs, flushing bung etc. Simple wound dressings, and where the staff member is experienced in urinary catheterization and IV cannulation standard aseptic technique may be adequate. 6. Surgical Aseptic technique > Technically complex procedures > Involve extended period of time > Large open key sites or large or numerous key parts > Require main critical aseptic field and sterile gloves and full barrier precautions > Use of critical aseptic fields and non-touch technique is used where practical to do so Examples include urinary catheterization in non-experienced staff member, IV cannulation with non-experienced staff member, plus complex / large dressings, PICC / CVC insertion & surgery. 7. Environment Control

5 Prior to conducting an aseptic procedure, health care workers should ensure that there are no avoidable environmental risk factors nearby such as bed making or patients using commodes. Key Parts 1.
