Aseptic technique

Aseptic Technique

  • Aseptic technique is a set of practices and procedures used to prevent the contamination of cultures, people and the environment.

  • The use of aseptic technique in laboratories and medical facilities is crucial to prevent the spread of microorganisms and ensure the reliability of results.

  • Aseptic technique relies on sterile work conditions. Sterilisation methods can include heat, radiation, filtration, or use of pressure and chemical agents.

  • Maintaining aseptic conditions involves the use of PPE, cleaning and disinfection of surfaces, and the use of sterile tools and materials.

Aseptic Technique Practices

  • Hand hygiene is the simplest and most effective measure to prevent the spread of microbes. This involves thorough hand washing and the use of hand sanitising products.

  • Use of PPE is vital - gloves, gowns, and face protection (masks, goggles) protect the wearer and also prevent the spread of pathogens.

  • Disinfecting surfaces and tools before and after use with suitable antimicrobial cleaners helps to maintain a sterile work environment. This also applies to the handling of samples and equipment.

  • Sterile barriers, such as sterile drapes, help maintain aseptic conditions during procedures. Barriers should be handled on the edges to avoid contamination.

  • Safe handling and disposal of sharps, such as needles and scalpel blades, is important to prevent injuries and maintain aseptic conditions.

Importance of Aseptic Technique

  • Aseptic technique helps to prevent the spread of infection in healthcare settings, safeguarding both patients and staff.

  • In the laboratory context, aseptic technique ensures that samples and experiments are not contaminated, thus maintaining the integrity of the results.

  • Non-compliance with aseptic technique can lead to cross-contamination, compromising patient safety, sample integrity and the reliability of the outcome of an experiment.

  • Aseptic technique is critical in procedures such as surgery, intravenous therapy and wound care in healthcare settings, and in microbial culture preparation and handling in laboratories.
