Introduction. In the microbiology lab we use aseptic technique to: Prevent contamination of the specific microorganism we are working with. Prevent contamination of the room and personnel with the microorganism we are working with.
Aseptic technique means using practices and procedures to prevent contamination from pathogens. It involves applying the strictest rules to minimize the risk of infection.
Examples of aseptic technique are cleaning and disin- fecting lab surfaces prior to use, limiting the duration that cultures or media are uncapped and exposed to the air, keeping petri dishes closed whenever possible, effectively steriliz- ing inoculating loops and other equipment that comes into contact with cultures …
Aseptic techniques refer to any method used to sterilize and maintain the sterility of an object or location, such as an operating theatre or laboratory, though it may also wound care to prevent infection.
- Inserting PICC lines.
- Performing dialysis.
- Inserting catheters.
- Running IVs.
- Inserting chest tubes.
- Performing surgeries.
- Dressing wounds.
These principles include the following: (1) use only sterile items within a sterile field; (2) sterile (scrubbed) personnel are gowned and gloved; (3) sterile personnel operate within a sterile field (sterile personnel touch only sterile items or areas, unsterile personnel touch only unsterile items or areas); (4) …
- disinfecting a patient’s skin using antiseptic wipes.
- sterilizing equipment and instruments before a procedure.
- keeping sterilized instruments inside plastic wrappers to prevent contamination before use.
Aseptic: A surface, object, product, or environment has been treated such that it is free of contamination. Bacteria, viruses, or other harmful living organisms cannot survive or reproduce. … Sterile: A product that is completely free of microscopic organisms.
There are two types of asepsis – medical and surgical. 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.

An aseptic technique is used to carry out a procedure in a way that minimises the risk of contaminating an invasive device, e.g. urinary catheter, or a susceptible body site such as the bladder or a wound.
Proper aseptic technique has prevented the cultures contamination from inborn and outborn microbes in the environment. … Appropriate aseptic techniques prevent microbes from unintentionally released into the environment and/or contaminating lab user in the laboratory.
Sterile technique. Sterile technique involves strategies used in patient care to reduce exposure to microorganisms and maintain objects and areas as free from microorganisms as possible.
- Close windows and doors to reduce draughts and prevent sudden movements which might disturb the air.
- Make transfers over a disinfected surface. …
- Start the operations only when all apparatus and materials are within immediate reach.
Which of the following best describes aseptic technique? … Aseptic technique is used to prevent environmental bacteria (e.g., from the air) from contaminating cultures. This is why we flame the mouths of the culture tubes before and after transferring bacteria. You just studied 32 terms!
