Both methods are presented in the form of general protocols applicable to a variety of laboratory tasks such as pipetting and dispensing aliquots, preparing growth media, and inoculating, passaging, and spreading microorganisms on petri dishes. It is important to decontaminate equipment such as trolleys prior to use. Pellowe describes ‘Poor adherence to evidence-based infection prevention measures and the subsequently increased risks to patients’ 18). During all procedures, key parts and key sites need to be identified and protected. Procedures which may require a critical aseptic field include: The micro critical aseptic field is a smaller version of the critical aseptic field and is used to protect a single key part. Find out where else germs live and how to keep those spots clean. ‘Aseptic technique’ aims to prevent pathogenic microorganisms, from being introduced to the patient via hands, surfaces and equipment. The safest way to protect a key part or site from contamination is to use a non touch technique. The correct practice of this technique requires the understanding of some principles and facts.

Key part and key site identification and protection. It is estimated that 30% of healthcare acquired infections are preventable. A critical aseptic field ensures asepsis during procedures. A key factor of aseptic non-touch technique is hand hygiene, which must be performed correctly to achieve a higher level of protection against pathogens. Aseptic technique qualification testing may be simply described: A properly trained technician executes an approved protocol requiring multiple aseptic transfers and contact tests using sterile supplies in a qualified aseptic work area. 2018 Jan; 19(1): 6–15. Maintaining a sterile environment requires keeping doors closed during an operation. To change a sterile dressing, a person needs sterile gloves and a special dressing change kit or supplies. Previously, the terms ‘sterile technique,’ ‘clean technique’ and ‘aseptic technique’ have been used interchangeably. A ‘key site’ is the area on the patient such as a wound, or IV insertion site that must be protected from microorganisms. Healthcare workers use aseptic technique in surgery rooms, clinics, outpatient care centers, and other health care settings. Department of Health (2015) The Health and Social Care Act 2008: Code of Practice on the prevention and control of infections and related guidance. Atlanta, GA: https://www.cdc.gov/HAI/pdfs/progress-report/hai-progress-report.pdf. protect patients from becoming colonized or infected: becoming colonized or infected by pathogenic microorganisms. Remove gloves, perform hand hygiene, re-apply new gloves. The goal of the clean technique is to reduce the number of germs whenever possible. Often, practices that clean (remove dirt and other impurities), sanitize (reduce the number of microorganisms to safe levels), or disinfect (remove most microorganisms but not highly resistant ones) are not sufficient to prevent infection. Failures of aseptic technique have long been thought to be associated with practice compromises 17). Sepsis is a serious infection that causes your immune system to attack your body. SOP: Aseptic Technique : The procedure for aseptically transferring microorganisms is as follows: 1. Healthcare providers also use sterile equipment and sterile instruments. 3.
