This is the safest way to avoid contamination of key sites and key parts (ACIPC 2015). After carrying out the procedure required, for example, withdrawing culture, replace the cap/ cotton wool plug on the bottle/ test tube using your little finger. Do not put the loop down, or wave it around. An aseptic technique aims to prevent pathogenic organisms, in sufficient quantity to cause infection, from being introduced to susceptible sites by hands, surfaces and equipment. In aseptic procedures, hand hygiene is used to ensure that: Clients are not infected via the staff member’s hands or their own flora; and What are the types of aseptic technique? List the common types of contamination that may occur when working in a laminar flow hood and describe how to minimize the risks of these types of contamination. An aseptic technique is one of the many educational programs people in the health care system are required to undergo as part of their vocational training.
Define the following terms: pure culture, sterile medium, inoculum, aseptic technique, and colony. Non-sterile gloves are appropriate otherwise (VIC DoH 2014). Do not put down the cap/ cotton wool plug.

In instances when the lid of the Petri dish may be removed for longer periods than normal, work very close to the Bunsen burner flame to reduce the chances of contamination. Barriers. The greatest source of contamination in a basically clean operation is the operative environment, a term that covers every other element in the operating room, from the nonscrubbed personnel to the air over the surgical wound. This leaves your little finger free to take hold of the cap/ cotton wool plug of a bottle/ test tube and your thumb free to control the teat. A major purpose of the open flame in aseptic technique is to create a cone of hot air above and around the laboratory bench to reduce the viability of organisms on suspended dust particles.

(Turn the bottle, not the cap.).
Aseptic technique aims to achieve asepsis during invasive clinical procedures - that is, the absence of sufficient pathogens to cause an infection in the client (VIC DoH 2014; NHMRC 2019). The founder of the technique is considered to be Joseph Lister. performing biopsies. Understanding what can contaminate a culture and how these contaminants behave is equally essential. dressing surgical wounds or burns. Very basic and intersting info, Thank you. If you experience frequent contamination of plates with fungal spores, reduce the chance of draughts further, and consider inoculating plates from below with the agar surface facing downwards.

Different types of aseptic techniques include dry heat, wet heat, ultrafiltration, chemical sterilization, antibiotics, and PPM™ . The aseptic field is the working space wherein key parts are held and protected from contamination. Used correctly, it provides the work space with clean, ultrafiltered air. Aseptic Techniques 2740 Words | 11 Pages. This could be either by the technical team preparing for and clearing up after a piece of practical work (for example, in the case of glassware to be used), or by the worker during the course of the practical (for example, in flaming a wire loop). Probably the easiest way to create a relatively sterile environment on the laboratory bench is by using a simple gaspowered burner. The aseptic technique is a set of measures that reduce the risk of infection in both patients and medical personnel. If we are to study, characterize, and identify microorganisms, we must have the organisms in the form of a pure culture, that is of only one species of microorganism. The organisation can then use this information to determine whether a reassessment of staff competency or other actions are required (ACSQHC 2018). This action aims to minimise the risk of HAIs being transmitted during clinical procedures by ensuring health service organisations implement a risk-based aseptic technique process (ACSQHC 2019). Aseptic procedures are used in microbiology.

An aseptic field is a controlled workspace used to promote asepsis during a clinical procedure. may be used as an alternative. If cotton wool plugs have partly lost their shape, they can be more easily guided back into the neck of the vessel by slowly twisting the mouth of the vessel as the plug is pushed down. Asepsis is achieved by protecting key-parts and key-sites from microorganisms transferred from the healthcare worker and the immediate environment. Note that a microincinerator does not provide other aseptic technique benefits of a lit Bunsen burner. Allow to cool for a few seconds in the air, then use immediately. The Joint Commission has recognized four major aspects of the aseptic technique which include: patient equipment and preparation, barriers, environmental controls, and t h e contact guidelines.

Hold the pipette barrel as you would a pen, but do not grasp the teat. How recently the specific staff member was assessed for competency in aseptic technique. Keep pipettes at the work area. Be careful not to talk, sing, or whistle while performing sterile procedures. Many of the organisms can be opportunistic in their abilities to cause infection. The type of aseptic technique required for a procedure is determined through a risk assessment which takes into account the complexity (ie. If you remove a cap or cover, and have to put it down on the work surface, place the cap with opening facing down. Then gently release the pressure until the required amount of liquid is drawn up, and lift the pipette tip out of the liquid. Aseptic techniques range from simple practices, such as using alcohol to sterilize the skin, to full surgical asepsis, which involves the use of sterile gowns, gloves, and masks. Squeezing the teat with the pipette tip beneath the liquid surface introduces air bubbles which may cause ‘spitting’ and, consequently, aerosol formation.

The aim is to determine whether there are any environmental risks present that could cause contamination through movement, touch or proximity (ACIPC 2015). It is recommended to wear gloves. For technicians, ethanol disinfection is recommended because of its rapid action (around 5 minutes).
There are two categories of asepsis: medical and surgical. Ensure staff are complying with aseptic technique policies. Medical or clean asepsis reduces the number of organisms and prevents their spread; surgical or sterile asepsis includes procedures to eliminate micro-organisms from an area and is practiced by surgical technologists and nurses.
