    Study Notes

    Aseptic Technique Overview

    • A sterile field reduces contamination risk during surgical procedures.
    • Proper understanding of sterile fields, gloves, and hand scrubbing is crucial for surgical safety.

    Incorrect Elements of a Sterile Field

    • Folding arms while wearing sterile gloves compromises their sterility.
    • A sterile field encompasses all draped areas, including tables and gowns.

    Contamination Definition

    • An object containing even one microorganism is classified as contaminated.
    • Sterilization removes all microorganisms; sanitation and disinfection lower microbial counts but don’t guarantee complete microbial free status.

    Masks and Proper Usage

    • Masks must ensure air filters through, preventing escape around edges.
    • Moisture reduces mask filtration effectiveness.
    • Masks should be properly secured with ties to maintain fit and effectiveness, ideally with one tie on top and another behind.

    Draping Techniques

    • Tables should be draped starting from the front to the back, using a cuffing technique to keep gloves sterile during the process.

    Hand Scrubbing Purpose

    • The scrub aims to render skin surgically clean, minimizing microbial presence, but does not achieve complete sterility.

    Steam Sterilization and Item Handling

    • Certain items, like suction tips and asepto syringes, may not maintain sterility post-steam sterilization.
    • Proper handling and placement during sterilization are critical for maintaining sterility.

    Gloving Techniques

    • Closed gloving technique is preferred to reduce contamination risk.
    • Open gloving may be necessary for changing a single glove during surgery.

    Pressure Steam Sterilizer Loading Protocol

    • Liquids should not be placed at the start to prevent spillage; they are last loaded.
    • Correct loading involves placing linen packs upright, canisters on sides, and mesh-bottom trays flat.

    Sterility Assumptions

    • Assume items are not sterile if there is any doubt.
    • The inner edges of wrappers are not sterile; sterility is maintained only in the center and on clean surfaces.

    Prep Site Scrubbing Protocols

    • Areas such as colostomies should be scrubbed last using disposable sponges to avoid contaminating already cleaned surfaces.

    Operating Room Cleaning Standards

    • Floors should be disinfected with a germicidal solution at the end of each case to ensure a sterile environment.
    • Merely using detergents without germicidal agents is insufficient for effective cleaning in an operating room context.
