Key parts are any parts of the equipment which come into contact with procedural equipment or the patient. Two major strategies of aseptic work are described: using a Bunsen burner and a laminar flow hood. sterile gloves and often, full barrier precautions (sterile gown, mask and hair covering and the use of sterile drapes) are required. Aseptic technique, designed to provide a barrier between the microorganisms in the environment and the sterile cell culture, depends upon a set of procedures to reduce the probability of contamination from these sources. central-line associated bloodstream infections) by more than 70% 11). It is important to decontaminate equipment such as trolleys prior to use. enable_page_level_ads: true Standard aseptic technique can be used when procedures: Standard aseptic technique requires the clinician to: Examples of procedures that may use standard aseptic technique include: These procedures may involve general aseptic fields and micro critical aseptic fields. Find out where else germs live and how to keep those spots clean. Aseptic techniques, defined as the process for keeping away disease-producing microorganisms, may be used in any clinical setting. It is estimated that 30% of healthcare acquired infections are preventable. Perform aseptic technique using the following core components: Key sites are any breaches in skin integrity which could be a portal of entry for microorganisms to colonise the patient. 2. Prior to performing an aseptic procedure, clinicians need to ensure that there are no environmental risks to the procedure. Even intentional cuts during surgery put you at risk for infection. Preventing the infection in the first place saves lives and money. A ‘key site’ is the area on the patient such as a wound, or IV insertion site that must be protected from microorganisms. These catheters drain urine from the bladder and are associated with catheter-associated urinary tract infections (CAUTIs). To protect patients from harmful bacteria and other pathogens during medical procedures, healthcare providers use aseptic technique. 2007 Sep; 15(6):567-73. 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. Atlanta, GA: https://www.cdc.gov/HAI/pdfs/progress-report/hai-progress-report.pdf. Before you need to change the dressing at home, a healthcare specialist should demonstrate the techniques and have you practice them. For example, an IV cannula which has been disconnected from fluids but left in situ is no longer aseptic. Ensuring asepsis and sterility of equipment, Pickering D, Marsden J. As a result of that attack, septic shock can occur and result in…, Methicillin-resistant Staphylococcus aureus (MRSA) is an infection caused by a type of Staphylococcus (staph) bacteria that’s resistant to many…, Clean intermittent self-catheterization is recommended when you have a condition that affects your ability to empty your bladder properly. The procedure is explained and discussed with the patient and verbal consent obtained. For example, when applying or changing dressings, an aseptic technique is used in order to avoid introducing infections into a wound 1). Identify and gather equipment for procedure. Aseptic technique is a process designed to protect patients during invasive clinical procedures by using infection prevention and control measures to minimise, where possible, the presence of pathogenic microorganisms (National Health and Medical Research Council, 2019). Loveday HP, Wilson JA, Pratt RJ, Golsorkhi M, Tingle A, Bak A, Browne J, Prieto J, Wilcox M, UK Department of Health. Previously, the terms ‘sterile technique,’ ‘clean technique’ and ‘aseptic technique… Aseptic Fields – provide a controlled working space that either ensures or promotes asepsis. (2009) National and State Healthcare Associated Infections Progress Report. Geneva: WHO https://apps.who.int/iris/bitstream/handle/10665/44102/9789241597906_eng.pdf;jsessionid=7AAA5AFC0959E127F30FB838787F4BB0?sequence=1.

Aziz AM. number of basic procedures must be followed when handling sterile equipment or working in a sterile environment Rowley S, Clare S, Macqueen S, Molyneux R. (2010) ANTT v2: An updated practice framework for aseptic technique. The Centers for Disease Control and Prevention (CDC) reports research indicating that healthcare providers and practitioners taking specific targeted steps can reduce some healthcare-associated infection (e.g. Aseptic technique is a method used to prevent contamination of wounds and other susceptible sites by ensuring that only sterile objects and fluids come into contact with these sites and that risk of contamination is minimized. Healthcare professionals commonly use clean techniques when they’re: While your home isn’t likely a surgery center, there may be a time when you or a loved one need aseptic technique. doi: 10.1177/1757177417720996 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5753945/, Association for Safe Aseptic Practice. They should be handled with a non touch technique where possible, or with sterile gloves if touching is unavoidable. For … Prior to accessing the IV again, it needs to be made aseptic once more. It aims to: The 5 moments of hand hygiene must always be used in conjunction with both standard and surgical aseptic technique. The correct practice of this technique requires the understanding of some principles and facts. Aseptic technique means using practices and procedures to prevent contamination from pathogens. A critical aseptic field ensures asepsis during procedures. It involves applying the strictest rules to minimize the risk of infection. They should avoid touching nonsterile items at all costs. Sampling for microbiological testing shall be performed prior to collecting samples for other purposes. Clean trolley/work surface with detergent and water or detergent wipe. Healthcare professionals are responsible for following clean and aseptic techniques. 2009 Jan 8-21; 18(1):26-31. Worthington T, Tebbs S, Moss H, Bevan V, Kilburn J, Elliott TS. Whenever your skin is opened, you’re vulnerable to infection. Pellowe describes ‘Poor adherence to evidence-based infection prevention measures and the subsequently increased risks to patients’ 18). Healthcare providers keep a patient’s surroundings as clean as possible, but they aren’t using sterile items or aseptic technique. Aseptic technique is a fundamental and important laboratory skill in the field of microbiology. Healthcare workers put them on or use them in specific ways that minimize exposure to germs. Infection Control Components of Aseptic Non Touch Technique (ANTT®). The aseptic technique involves the use of procedures and practices that will avoid contamination by pathogens. Key part and key site identification and protection. Identify and protect key parts and sites. drop sterile equipment into sterile field. The assistant then moves the animal to a recovery area, or directly into a warm incubator. The practitioner undertaking the procedure is bare below the elbows (BBE) and any cuts/grazes are covered with a waterproof dressing. According to the Journal of the American Medical Association (JAMA) Internal Medicine, 50 percent of HAIs are preventable. Aseptic technique is employed to maximize and maintain asepsis, the absence of pathogenic organisms, in the clinical setting. Microbiologists use aseptic technique for a variety of procedures such as transferring cultures, inoculating media, isolation of pure cultures, and for performing microbiological tests. It is recommended to wear gloves. However, some situations call for aseptic technique while others call for clean techniques. Multiple reservoirs contribute to intraoperative bacterial transmission. Maintaining a sterile environment requires keeping doors closed during an operation. Well, bacterias are everywhere, some bacterias are good and some are harmful to us. In a right hand–dominant physician the left index finger is used to depress the carotid artery laterally and posteriorly. Sepsis is a serious infection that causes your immune system to attack your body. Healthcare providers learn both aseptic and clean techniques as part of their training. Gloves are a single-use item. Hartley 14) reports that aseptic technique is not carried out to a high standard across the UK and Flores 15) suggested that there was a theory–practice gap along with much confusion and complacency in professional practice regarding aseptic technique. Otherwise, non sterile gloves may be used. Anesth Analg. (2013) Point prevalence survey of healthcare-associated infections and antimicrobial use in European acute care hospitals 2011–2012. The Centers for Disease Control and Preve… This decision must be based on a risk assessment which considers: Sterile means free from bacteria or other living microorganisms. Note: Proper aseptic techniques require training. Otherwise, non sterile gloves may be used. Sterilise the inoculating loop. If you notice that someone fails to wash hands or sterilize equipment, speak up. After completing the first procedure, the surgeon lifts and disposes of the sterile drape. Remove gloves, perform hand hygiene, re-apply new gloves. 2015;28(89):17. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4579997/, World Health Organization. It involves applying the strictest rules to minimize the risk of infection. In this way all contaminants on the wire are incinerated. Aseptic technique is an important infection prevention competency for protecting patients from healthcare-associated infection 8). people who get dialysis often have multiple chronic conditions that can make it even harder to get over an infection. The goal of the aseptic technique is to eliminate germs entirely. less than 20 minutes), protect those key parts and key sites from contamination during the procedure, decontaminate non aseptic key parts as required, preparation and administration of IV fluids or medications, involve a large number of key parts or key sites, involve large sized key parts or key sites, are long in duration (e.g. The decision to use standard or surgical aseptic technique must be based on a risk assessment. Sterile gloves should be worn if a touch a key part or key site needs to be touched, or if it is likely that they may accidentally be touched, during the procedure. Healthcare acquired infections result in significant mortality and morbidity internationally. can’t be handled with non touch technique at all times, involve a small number of key parts and key sites, are short in duration (e.g. Techniques for aseptic dressing and procedures. The goal of the clean technique is to reduce the number of germs whenever possible. Aseptic technique is a process or procedure used to achieve asepsis to prevent the transfer of potentially pathogenic micro-organisms to a susceptible site that may result in the development of infection (Wilson, 2019). According to the Centers for Disease Control and Prevention (CDC), an estimated 37,000 CLABSIs happen each year in people who get dialysis. Aseptic technique should be used in the external approach. What is aseptic technique. 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. Wipe the outside of the containers, flasks, plates, and dishes with 70% ethanol before placing them in the cell culture hood. Teaching your kids to have a healthy hygiene routine when they’re young can create habits that last throughout their lives. A general aseptic field promotes asepsis during procedures. Contact guidelines: Healthcare providers take great care not to touch any nonsterile surface with the hand that advances the catheter into the patient’s urethra. Healthline Media does not provide medical advice, diagnosis, or treatment. If gloves are not used, it is necessary to wash hands before and after testing. 3. The choice of aseptic field should be made to ensure protection of key parts and sites. Outside the OR, aseptic technique is sometimes called medical asepsis or clean technique.Â²Â HCWs who are facilitating bedside surgical dressings, for instance, do not have the luxury of a highly controlled environment such as an OR, but the procedure still requires hand washing, use of PPE, the creation of a sterile field and the avoidance of non sterile items. Perform procedure ensuring all key parts/components are protected: sterile items are used once and disposed into waste bag. (2005) Aseptic technique to be part of Essence of Care Guidance. The micro critical aseptic field is a smaller version of the critical aseptic field and is used to protect a single key part. It also protects the people in the lab from exposure to pathogens. Definition: Invasive Procedures • Acts done to patients that come in contact with wounds, the blood stream, the inside of the body, or normally sterile parts of the body • Invasive procedures invade the inside of the body • Aseptic or Sterile techniques are used in invasive procedures 2. Proper aseptic technique prevents contamination of cultures from foreign bacteria inherent in the environment. 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. Epic3: national evidence-based guidelines for preventing healthcare-associated infections in NHS hospitals in England. Purpose Aseptic technique is employed to maximize and maintain asepsis, the absence of pathogenic organisms, in the clinical setting. 3. Aseptic technique protects patients during invasive clinical procedures by employing infection control measures that minimize, as far as practicably possible, the presence of pathogenic organisms. Basic aseptic procedures includes hand washing, donning protective gloves, masks and gowns, and sterilizing equipment and linens. A critical aseptic field ensures asepsis during procedures when key parts or key sites cannot be easily protected. 8.0 Indications for using an aseptic technique An aseptic technique should be used during any invasive procedure that Failures of aseptic technique have long been thought to be associated with practice compromises 17). This technique is a very important technique to prevent the sample of contamination. These include: Each of these infections represents a major healthcare concern. This includes wounds and puncture sites. Loftus RW, Brown JR, Koff MD, Reddy S, Heard SO, Patel HM, Fernandez PG, Beach ML, Corwin HL, Jensen JT, Kispert D, Huysman B, Dodds TM, Ruoff KL, Yeager MP. A common procedure that carries a risk for infection is inserting a urinary catheter. The term asepsis can be defined as “freedom from infection or infectious (pathogenic) material” (Taylor, 2019). These environments often have high-efficiency particulate (HEPA) filters that can remove around 99.9% of mi… The aim of every procedure should be to maintain asepsis at all times by protecting the key parts and key sites from contact contamination by microorganisms. Good aseptic technique procedures help prevent and control healthcare associated infections. Centers for Disease Control and Prevention (CDC), Journal of the American Medical Association (JAMA) Internal Medicine, Debra Sullivan, Ph.D., MSN, R.N., CNE, COI, Debra Rose Wilson, Ph.D., MSN, R.N., IBCLC, AHN-BC, CHT, masks for the patient and healthcare provider. Sterile Handling 1. }); What is the purpose of aseptic technique? http://antt.org/ANTT_Site/home.html, European Centre for Disease Prevention and Control. key parts/sites are large or numerous and can’t be easily protected by covers or caps or can’t be handled with a non-touch technique, invasive procedures require a large aseptic working area, the critical aseptic field is managed as a key part so that only sterile equipment can come into contact with it. Treating these infections costs an average of $23,000. The term ‘sterile technique’ should not be used in place of the term aseptic technique. It has to do with following rules strictly to reduce the likelihood of developing an infection. Controlled environments such as specially equipped operating theaters can achieve near-sterile techniques. To further protect the patient, they apply cleansing and bacteria-killing preparations to the patient’s skin before a procedure. The safest way to protect a key part or site from contamination is to use a non touch technique. General Sampling Process under the Aseptic Technique : Sample documentation procedures shall be followed for intimations and sample processing (refer to the current version of SOP for Microbiological Culture Management. Surgical aseptic technique is required when procedures: Surgical aseptic technique requires the clinician to: Examples of procedures that may use surgical aseptic technique include: Due to the high risk of contamination of key parts or key sites, a critical aseptic field and sterile gloves are required. protect patients from becoming colonized or infected: becoming colonized or infected by pathogenic microorganisms. Some barriers used in aseptic technique include: Sterile barriers are those that have not touched a contaminated surface. non sterile gloves can be used unless key parts must be touched, when sterile gloves must be worn. The aim of every clinical procedure should be to maintain asepsis at all times by protecting the key parts and key sites from contact contamination by microorganisms. SOP: Aseptic Technique : The procedure for aseptically transferring microorganisms is as follows: 1. Did you know your kitchen is most likely the dirtiest spot in your home? They prepare the patient’s skin with a special solution. J Hosp Infect. Aseptic technique procedure audit tool Yes No N/A 1. A ‘key part’ is the part of the equipment that must remain sterile, such as a syringe hub, and must only contact other key parts or key sites. To change a sterile dressing, a person needs sterile gloves and a special dressing change kit or supplies. 2001 Sep; 49(1):81-3. Aseptic technique should be used when the patient has a surgical or non-surgical wound in or around the eye. (2009) World Health Organization Guidelines on Hand Hygiene in Health Care: First Global Patient Safety Challenge Clean Care is Safer Care. With the right hand, a 2.5-cm, 25-gauge needle and syringe combination is “walked off” the cornu of the hyoid bone Fig. The more people present, the more opportunities for harmful bacteria to cause contamination. It would be nearly impossible to achieve sterile technique during all procedures due to the large numbers of microorganisms present on the human body and in the health care environment. Increasingly, modern technology enabling organisms to be tracked around the procedure environment is providing evidence for the role of failed aseptic technique in the transmission of infection 19). The technique is achieved by identifying and protecting key sites (such as wounds or puncture sites) and key parts (equipment that c… Sequence your practice to ensure efficient, logical and safe order of tasks. Asepsis is achieved by protecting key-parts and key-sites from microorganisms transferred from the healthcare worker and the immediate environment. It is used when key parts or key sites cannot be easily protected from contamination during a procedure. Medical facilities are required to report their infection rates to the federal government. During all procedures, key parts and key sites need to be identified and protected. Environmental controls: Only one or two providers and the patient are in the room. Healthcare workers use aseptic technique in surgery rooms, clinics, outpatient care centers, and other health care settings. 2018 Jan; 19(1): 6–15. J Hosp Infect. 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. 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. In this lab you will learn how to: 1. decontaminate your lab bench 2. safely organize your workspace 3. properly adjust your Bunsen burner 4. properly use an incinerator 5. sterilize your inoculating tools 6. aseptically transfer organisms from broth/plate cultures using BSL 2procedures 7. handle biohazard spills and dispose of bi… Pellowe C. J Nurs Manag. Aseptic technique is variously and confusingly described in the literature and problematic in practice. Br J Nurs. Patient and equipment preparation: They open sterile packaging that contains the sterile catheter. Aseptic technique, designed to provide a barrier between the microorganisms in the environment and the sterile cell culture, depends upon a set of procedures to reduce the probability of contamination from these sources. The aseptic technique is a method of preventing the transmission of infection to the patient during the performance of various clinical procedures. (2008) Surgical Site Infections: Prevention and Treatment. 2014 Jan; 86 Suppl 1():S1-70. Aseptic technique is a standard healthcare practice that helps prevent the transfer of germs to or from an open wound and other susceptible areas on a patient’s body. These surfaces can be easily cleaned and are resistant to scratches. Always wipe your hands and work area with 70% ethanol. For example, you may need to change a dressing on a wound, and that requires a sterile dressing. This can be achieved through correct hand hygiene, a non-touch technique, glove use and ensuring asepsis and sterility of equipment. In the European Union and European Economic Area it has been estimated that approximately 3.2 million patients per year will have at least one healthcare-associated infection 10). ‘Aseptic technique’ aims to prevent pathogenic microorganisms, from being introduced to the patient via hands, surfaces and equipment. A widely used method of aseptic technique is known as Aseptic Non Touch Technique (ANTT®). *Treat all organisms … The vocabulary of aseptic technique is often inaccurate, used interchangeably, confusing and lacking in evidence, all of which appears to have contributed to practice variability, inadequate risk assessment and uncontrolled standards of practice 16).
