Sterile field rules

Sterile Field RULES:

  • Never work across the sterile field

  • Always keep sterile items above waist and in vision

  • Never turn back to sterile tray/item

Opening an sterile package

Opening an sterile package

  • Three methods of adding a sterile item to a sterile field:

    • Drop technique

    • Mitten technique

    • Sterile gloves

  • To open a sterile package:

    • Ascertain the package is sterile

    • Hold with sealed edge TOWARD YOU

    • Only touch exterior of wrap (Tabs)



  • While performing drop technique the wrap is opened maintaining sterility of inside of wrap and item. The item is dropped onto sterile field without touching you, exterior of wrap of the outside perimeter of sterile field. Used most commonly for gauze pads, dressings and small items.

  • With mitten technique, a mitten is formed with the wrapper around the hand holding the item. Special care to maintain sterility of item and inside of wrap. DO NOT let the wrap drag onto the sterile field. Commonly used for bowls,drapes, linen and odd shaped items.

  • Transfer forceps, Using sterile gloves or transfer forceps remove item from container and place it on the sterile field.

Preparing a sterile tray

Preparing a sterile tray

  • Once there is a sterile tray it must be maintained as sterile. So…..

    • Contaminated items stay off the tray

    • Solutions are poured without touching bowl or working over sterile field.

    • Drop, mitten and sterile gloves are used.

    • Dressings that are used last are applied to the tray first.

    • Follow all the “rules”

    • If contamination occurs….start over.

Donning and Removing Sterile gloves

  • How in the heck do you put two sterile gloves on two non-sterile hands and keep the exterior of the gloves sterile?????

  • And why???

  • Once gloves are correctly on your hands you may ONLY touch sterile items.

Sterile technique

  • Assemble sterile glove and ascertain sterility

  • Remove jewelry, wash & dry hands

  • Open inner wrap handling only OUTSIDE of wrap.

  • Don first glove by grasping cuff (inside of glove)

  • Don second glove by grasping under cuff

  • Pull on second glove with extreme care not to touch exterior of second glove. (FLY your thumb)

  • Only touch sterile surfaces

  • If not in use keep fingers together in “prayer position” and away from body
