Study Notes
Types of Aseptic Techniques
- Three main types of aseptic techniques are used in medical settings: Sterile, Surgical, and Standard.
- Sterile technique is the strictest form, used in surgeries and invasive procedures to provide a germ-free space.
- Surgical aseptic technique is a strict form used outside the operating room for complex procedures.
- Standard aseptic technique is the most common type, used for procedures like dialysis and IV insertions.
Aseptic Technique vs. Clean Technique
- Aseptic technique aims to eliminate germs, while clean technique focuses on reducing microorganisms.
- Sterile gloves are required for procedures like central line dressing changes, insertion of urinary catheters, and invasive surgical procedures.
Sterile Fields
- A sterile field is established when a patient's skin is intentionally punctured or incised, or when contact with non-intact skin is possible.
- Surgical asepsis requires adherence to strict principles to prevent contamination and maintain sterility.
- Creating and maintaining a sterile field involves handwashing, using sterile barriers, preparing the patient with an antimicrobial product, and maintaining a sterile field.
Procedures Involving Aseptic Technique
- Procedures that involve aseptic technique include inserting PICC lines, performing dialysis, inserting catheters, running IVs, inserting chest tubes, performing surgeries, and dressing wounds.
Elements of Aseptic Technique
- Aseptic technique uses four strategies to keep things clean: barriers, contact guidelines, tool and patient preparation, and environmental controls.
- Barriers prevent germs from getting on the patient, including masks, sterile gloves, and gowns.
- Contact guidelines ensure that sterile objects remain sterile, and any object that touches a non-sterile object is considered non-sterile.
- Tool and patient preparation involves sterilizing tools and equipment with heat or alcohol, and treating the patient's skin with antiseptic.
- Environmental controls involve creating an "aseptic field" to prevent germs from entering the area.
Learn about the three main types of aseptic techniques used by medical professionals, including the strictest form known as sterile technique. Understand the importance of maintaining a germ-free environment in surgeries and invasive procedures.
