Medical asepsis means9/27/2023 Biological indicators indicate that all the parameters necessary for sterilization were present.īloodborne pathogens: disease-producing microorganisms spread by contact with blood or other body fluids contaminated with blood from an infected person.īloodborne Pathogens Standard: a standard developed, promulgated, and enforced by the Occupational Safety and Health Administration (OSHA) directing employers to protect employees from occupational exposure to blood and other potentially infectious material. The term is a misnomer because it is not cleared by the FDA as a sterilizer.īioburden: the microbiological load (i.e., number of viable organisms in or on the object or surface) or organic material on a surface or object prior to decontamination, or sterilization, also known as “bioload” or “microbial load.”īiological indicator: a device to monitor the sterilization process that consists of a standardized population bacterial spores known to be resistant to the mode of sterilization being monitored. The term also refers to the estimated number of bacteria per unit sample, usually expressed as colony-forming units (CFUs) per square centimeter (cm2) per milliliter (ml).īacterial endocarditis: a bacterial induced inflammation of the lining of the heart and its valves.īead sterilizer (endodontic dry heat sterilizer): a device that used small glass beads (1.2–1.5 mm diameter) and high temperature (217–232oC) for brief exposures (e.g., 45 seconds) to inactivate microorganisms. Bīacterial count: a method of estimating the number of bacteria per unit sample. Includes sterile conditions on tissues, on materials, and in rooms, as obtained by excluding, removing, or killing organisms. The process of applying an antiseptic hand-rub product to all surfaces of the hands to reduce the number of microorganisms present.Īsepsis: prevention from contamination with microorganisms. Examples include alcohols, chlorhexidine, chlorine, hexachlorophene, iodine, chloroxylenol (PCMX), quaternary ammonium compounds, and triclosan.Īntiseptic handwash: washing hands with water and soap or detergents containing an antiseptic agent. Antibodies protect the body from disease by binding to these organisms and destroying them.Īntigen: a foreign substance, usually protein or carbohydrate substance (as a toxin or enzyme) capable of stimulating an immune response, usually the production of antibodies.Īntimicrobial soap: a soap (i.e., detergent) containing an antiseptic agent.Īntiseptic: a germicide that is used on skin or living tissue for the purpose of inhibiting or destroying microorganisms. Anaphylaxis is characterized commonly by respiratory symptoms, itching, hives, and rarely by shock and death (anaphylactic shock).Īntibody: a protein found in the blood that is produced in response to foreign substances (e.g., bacteria or viruses) invading the body. Reactions occur slowly over 12-48 hours.Īnaphylaxis (immediate anaphylactic hypersensitivity): a severe and sometimes fatal Type 1 reaction in a susceptible person after a second exposure to a specific antigen (e.g., food, pollen, proteins in latex gloves, or penicillin) after previous sensitization. ![]() After applying such an agent, the hands are rubbed together until the agent has dried.Īllergen: an antigen, a substance capable of inducing allergy or specific hypersensitivity.Īllergic contact dermatitis: a type IV or delayed- hypersensitivity reaction resulting from contact with a chemical allergen (e.g., poison ivy, certain components of patient care gloves), generally localized to the contact area. These are waterless antiseptic agents not requiring the use of exogenous water. In the United States, such preparations usually contain 60%–95% ethanol or isopropanol. « A B C D E F G H I J K L M N O P Q R S T U V W X Y Z »Īdministrative controls: the use of administrative measures (i.e., policies and procedures and enforcement measures) to reduce the risk of exposure to pathogenic organisms.Īerosol: particles of respirable size (<10 µm) generated by both humans and environmental sources that can remain viable and airborne for extended periods in the indoor environment commonly generated in dentistry during use of handpieces, ultrasonic scalers, and air/water syringes.Īirborne transmission: a means of spreading infection in which airborne droplet nuclei are inhaled by the susceptible host.Īir abrasion: the application of a mixture of small abrasive particles by air blast to prepare a cavity in a tooth or remove deposits from teeth.Īlcohol-based hand rub: an alcohol-containing preparation designed for application to the hands for reducing the number of viable microorganisms on the hands.
