#SURGICAL ASEPSIS SKIN#
The skin cannot be sterilized and is unsterile.The edges of a sterile field are considered unsterile.Moisture that passes through a sterile object draws microorganism from unsterile surfaces above or below to the surface by capillary reaction.Fluids flow in the direction of gravity.Sterile objects can become unsterile by prolong exposure to airborne microorganisms.Sterile items that are out of vision or below the waist level of the nurse are considered unsterile.Sterile objects become unsterile when touched by unsterile objects.Principles of Aseptic Technique Only sterile items are used within sterile field. Used for all procedures involving sterile areas of the body.Practices that destroy all microorganisms and spores.Practices that keep an area or object free of all microorganisms.Objects referred to as clean or dirty (soiled, contaminated).Limits the number, growth, and transmission of microorganisms.Includes all practices intended to confine a specific microorganism to a specific area.The term asepsis often refers to those practices used to promote or induce asepsis in an operative field in surgery or medicine to prevent infection.
