UNIT 1: SURGICAL ASEPSIS & STERILE TECHNIQUE:
SURGICAL ASEPSIS: Aseptic technique is a set of practices that prevents the introduction
of pathogens into patients during clinical procedures.
STERILE TECHNIQUE: Sterile technique is the use of practices that restrict microorganisms
in the environment and prevent contamination of the surgical field. Sterility will apply to
surfaces of some objects or to substances that will be introduced into a patient's body.
PRINCIPLES OF ASEPSIS & STERILE TECHNIQUE:
PRINCIPLES OF ASEPSIS: Aseptic technique is a set of principles that help prevent the
introduction of pathogens during clinical procedures. Some key principles of aseptic
technique include:
Sterile field: Create a sterile field by placing sterile towels around the procedure site
and on the surface for sterile instruments and dressings. Sterile fields must be kept in
view and remain sterile.
Sterile items: Use only sterile items within a sterile field. If a sterile item touches a
non-sterile item, it becomes non-sterile.
Sterile people: All people who touch sterile items must be sterile.
Non-sterile people: Non-sterile people should not reach across a sterile field.
Personal protective equipment (PPE): Use the correct selection and use of sterile and
non-sterile PPE.
Respiratory hygiene: Practice respiratory hygiene and cough etiquette.
Environmental cleaning: Clean and disinfect the environment.
Healthcare provider hygiene: Healthcare providers should maintain good personal
hygiene, be current with recommended immunizations, and not work when sick.
PRINCIPLES STERILE TECHNIQUE:
Use sterile items: Only use sterile items within a sterile field. This includes sterile
gowns, gloves, and masks.
Maintain a sterile field: Keep the sterile field in view and only allow sterile supplies
within it.
Check packaging: Before using any supplies, check the packaging for damage, such
as holes or tears.
Open sterile packets carefully: Open sterile packets carefully to avoid contaminating
the sterile equipment and surfaces.
Wash hands: Practice proper handwashing.
Use single-use instruments: Use single-use instruments when possible.
Clean and sterilize equipment: Properly clean and sterilize all equipment.
