    Study Notes

    Surgical Asepsis

    • Surgical asepsis eliminates all microorganisms, including spores, from an area or object, differing from medical asepsis.
    • Use surgical asepsis when:
      • Intentionally perforating skin (e.g., IV catheter insertion).
      • Skin integrity is compromised due to trauma or burns.
      • Inserting instruments into sterile body cavities.

    Patient Preparation

    • Explain procedures to patients to prevent contamination.
    • Advise patients to:
      • Avoid sudden movements under sterile drapes.
      • Refrain from touching sterile supplies.
      • Avoid respiratory disruptions (coughing/sneezing) over sterile areas.
    • Separate soiled linen and wash with hot water and bleach.

    Principles of Surgical Asepsis

    • A sterile object can only be touched by another sterile object to remain sterile.
    • Contamination occurs when:
      • Sterile objects touch non-sterile items (e.g., the tip of a syringe touching clean gloves).
      • Sterile items touch fallible surfaces (e.g., torn packaging).
    • Only sterile objects may be placed on a sterile field, which should remain visible at all times.
    • Avoid prolonged exposure to air to prevent contamination.

    Maintaining a Sterile Field

    • Limit movement when handling sterile items.
    • Moisture from contaminated surfaces can lead to contamination.
    • Hold hands above elbows during surgical hand scrubs to allow water to flow downward.
    • The edges of a sterile field are considered contaminated, and items must be placed inside a 2.5-cm border.

    Performing Sterile Procedures

    • Prepare all necessary equipment before starting.
    • Any contamination during procedures warrants immediate discarding of the object.
    • Wear a surgical mask, cap, and eyewear for sterile procedures; replace masks when moist.

    Opening Sterile Packages

    • Sterile items must be dry and intact to be considered safe for use.
    • Always open sterile items on a flat, clean surface, maintaining a spacious and unobstructed work area.
    • Follow specific steps to prevent contamination when opening sterile packages.

    Preparing a Sterile Field

    • Utilize the inner surface of sterile wrappers as a work surface.
    • Sterile items are added carefully to avoid breaching the 2.5-cm contamination border.

    Pouring Sterile Solutions

    • Pour solutions carefully, avoiding the edges of the sterile field.
    • Ensure the bottle cap does not touch sterile surfaces to prevent cross-contamination.
    • Discard unused solutions at the end of each procedure.

    Surgical Hand Scrub

    • Essential for reducing infection risk when assisting in surgical procedures.
    • Perform scrubs from fingertips to elbows using antiseptic products.
    • Maintain clean and short nails; avoid jewelry and artificial nails during scrubs.

    Applying Sterile Gloves

    • Use sterile gloves to prevent bacterial transfer during procedures.
    • Closed gloving is used in sterile environments, such as operating rooms.

    Donning a Sterile Gown

    • Sterile gowns are worn in operating rooms to reduce contamination risk.
    • Only the front area from the waist (excluding collar and back) is considered sterile.
    • Gloves should fit snugly and be the appropriate size to avoid tearing.
