Asepsis Terms

Terminology of asepsis and sterile technique

Asepsis Absence of pathogenic microorganisms
Antiseptic Substance commonly used on living tissue to inhibit the growth an reproduction of microbes to prevent infection
Aseptic technique Methods practiced by the surgical team to prevent microbial contamination of the surgical environment
Bacteriocidal Substance that destroys/kills bacteria
Bacteriostatic Substance that inhibits the growth and reproduction of bacteria
Bioburden The number of microbes or amount of organic debris on an object at any given time
Contamination The presence of pathogenic materials
Cross-contamination The contamination of a person or object by another
Decontamination To reduce to an irreducible minimum the presence of pathogenic material
Disinfectant Chemical agent that kills most microbes, but usually not spores; usually used on inanimate objects because these compounds are too strong to be used on living tissues
Event-related sterility Sterility determined by how a package is handled rather than time elapsed; a package is considered sterile until opened or the integrity of packaging material is damaged
Fomite Inanimate object that harbors fungus
Fungicide Agent that destroys fungus
Infection Invasion of the human body or tissue by pathogenic microorganisms that reproduce and multiply, causing disease
Nosocomial Infection acquired within a health care facility
Pathogen Any microbe capable of causing disease
Resident flora Microbes that normally reside below the skin surface or within the body
Sepsis Infection, usually accompanied by fever, that results from the presence of pathogenic microorganisms
Spore A resistant form of certain types of bacteria that are able to survive in adverse conditions
Sporicide Substance that kills/destroys bacteria in the spore stage
Sterile Having been rendered free of all living microorganisms, including spores
Sterile field Specified area, usually the area immediately around the patient, that is considered free of microorganisms
Sterile technique Techniques of creating a sterile field and performing within the sterile field to keep microbes at an irreducible minimum
Sterilization The destruction of all microorganisms including spores, on inanimate surfaces through the use of steam or chemical sterilization, electron bombardment, or irradiation
Strike-through contamination Contamination of a sterile field that occurs through the passage of fluid through, or a puncture in, a microbial barrier
Surgically clean Mechanically cleaned and chemically disinfected, but not sterile
Terminal disinfection To render items safe to handle by high-level disinfection
Terminal sterilization To render items safe to handle by sterilization
Transient flora Microbes that reside on skin surface and are easily removed
Vector Living carrier that transmits disease
Virucide Agent that destroys viruses
