Asepsis Terms
Terminology of asepsis and sterile technique
| Question | Answer |
|---|---|
| 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 |
