Use of Aseptic Technique and Sterile Dressings

Use of Aseptic Technique

Aseptic technique is a method designed to prevent contamination from microorganisms. It is often used in medical procedures.
In healthcare, the goal of using aseptic technique is to minimize or prevent the risk of introducing harmful germs into a person’s body during procedures such as surgery, inserting catheters, etc.
Aseptic techniques include actions such as handwashing, sterilising instruments, and using gowns, masks, and gloves appropriately.
The application of aseptic technique in any procedure is based on the key principle of ‘asepsis’, which means the absence of potentially harmful germs.
Healthcare professionals must be thoroughly trained in aseptic techniques to prevent healthcare-associated infections.
The steps of the aseptic technique must be carried out precisely to be effective. For example, not touching anything non-sterile while applying sterile techniques, and opening sterile packages in a way to avoid contamination.

Sterile dressings are used to cover wounds to prevent contamination and infection. They are free from any microorganisms and provide a barrier to bacteria and other germs.
When applying a sterile dressing, it’s important to use aseptic technique to keep the wound and the area around it as clean as possible.
Never touch the part of the dressing that will be in contact with the wound.
When removing a sterile dressing from its packaging, only touch the edges of the dressing. If you touch the centre - which will cover the wound - it is no longer sterile.
While applying the dressing, do not allow it to come in contact with other non-sterile surfaces. A dropped dressing is considered contaminated and should not be used.
To maintain efficacy and sterility, dressings should be changed regularly and as often as instructed by a healthcare professional.
Sterile dressings need to be stored correctly in a cool, dry place to maintain sterility. The packaging should be checked before use to ensure it is sealed and has not been damaged.
