Aseptic Techniques Used in Health-Related Laboratories

  • Aseptic technique is a set of practises designed to prevent contamination from harmful microorganisms during medical procedures or in laboratories.

  • This method is vital to preventing the spread of infections in healthcare settings, especially in clinical laboratories and during surgical procedures.

  • In a laboratory setting, the use of laminar airflow cabinets/systems (also known as biohazard cabinets) is one way to create an aseptic environment. These cabinets sterilise the air and create a contaminant-free workspace.

  • Sterilisation of equipment is an essential part of aseptic technique. This can be achieved through various methods including heat (autoclaving), chemicals (disinfectants), pressure, or radiation.

  • The use of Personal Protective Equipment (PPE) such as gloves, gowns, masks, and goggles is integral to the aseptic technique. This not only protects the individual but also prevents any potential contamination from the person to the environment or patient.

  • Hand hygiene is of utmost importance in aseptic technique. This usually encompasses the use of soap and water washing, as well as sanitising with an alcohol-based hand gel.

  • Proper disposal of waste is crucial to maintain an aseptic environment. This includes biohazard waste, sharps, and other potentially contagious materials.

  • When handling cultures, samples or equipment, one should avoid direct contact with them to prevent cross-contamination.

  • Sterile packaging materials are used to keep sterilised tools and equipment safe until they’re ready for use. After sterilisation, they are covered or wrapped to keep them free from contamination.

  • Correctly following protocols and procedures for particular experiments or procedures is essential in maintaining an aseptic environment. This includes behaving responsibly in the lab space, not rushing procedures, and following instructions carefully.

  • Regular cleaning and disinfection of workspaces is another crucial part of maintaining aseptic conditions. Different surfaces or areas may need different cleaning techniques or products.

  • Finally, regular checks and auditing of techniques are necessary to maintain a high standard of aseptic technique and identify any potential areas for improvement.
