Study Notes

Surgical Asepsis or Sterile Technique

The purpose of surgical asepsis or sterile technique is to prevent contamination of a patient, healthcare provider, or equipment, reducing the risk of infection.

Sterile Field

A sterile field should include only necessary items, such as sterile gloves, instruments, and supplies, to minimize the risk of contamination.
All items placed on a sterile field must be sterile.

Contamination

A sterile object or field becomes contaminated when it comes into contact with a non-sterile object or surface.
Contamination can occur through direct contact, airborne transmission, or capillary action.
Capillary action leads to contamination of a sterile surface when a fluid or moisture flows from a non-sterile surface to a sterile surface through a narrow channel or passageway.

Sterile Field or Container

An item or surface is considered contaminated in a sterile field or container if it comes into contact with a non-sterile object or surface.
Any item or surface that is touched by an unsterile glove or object is considered contaminated.

Working with Fluids

To prevent contamination of a sterile area, avoid splashing or spilling fluids, and handle them carefully to minimize the risk of leakage.

Leaving the Room

If it is necessary to leave the room when working with a sterile tray, cover the tray with a sterile drape or cover to prevent contamination.

Contamination of Sterile Object

Actions that can result in contamination of a sterile object include:
- Touching the object with an unsterile glove or object.
- Placing the object on a non-sterile surface.
- Allowing the object to come into contact with a non-sterile fluid or moisture.

Sterile Supplies

To ensure the sterility of sterile supplies, handle them carefully, and store them in their original packaging or in a sterile container.
Keep the work area above the waist when assembling supplies for a sterile procedure to prevent contamination from the floor or lower surfaces.

Dated Labels or Chemical Tapes

The purpose of using dated labels or chemical tapes on sterile supplies is to ensure that they are used within a specific time period and to track their expiration dates.

Pouring Sterile Solution

To maintain the sterility of a sterile solution when pouring, use a sterile pouring technique, and avoid touching the lip or nozzle of the container to a non-sterile surface.

Inspecting Supplies

It is important to inspect the supply for package integrity and sterility before using it in a sterile procedure to ensure that it is not damaged or contaminated.

Opening Packages

The recommended method for opening packages of sterile supplies is to use a sterile technique, such as tearing or cutting the package with a sterile instrument, to minimize the risk of contamination.

Sterile Supplies Storage

Sterile supplies should never be kept in the same room as dirty equipment to prevent cross-contamination.
