Surgical procedures are performed under sterile conditions contamination with microorganisms is prevented to maintain sterility throughout the procedure. No special technique in handling is observed.

Principles of aseptic technique skin#

Items that will come into contact with only intact skin or mucous membranes in an area remote from the surgical site may be cleaned, terminally disinfected, and stored unsterile between patient uses. Other items are terminally sterilized between uses on different patients, but sterility is not maintained during storage or use. Some items are disinfected immediately before use and are handled using aseptic technique to prevent contamination before use. These items are clean and safe to handle with bare hands (i.e., mechanically cleaned and disinfected to reduce microorganisms, but unsterile). Sterility is less critical for items that come into contact with intact skin or mucous membranes. These items are handled using sterile technique to maintain sterility.

Principles of aseptic technique free#

Any item entering the bloodstream, body tissues underlying the skin, and mucous membranes must be sterile (i.e., free of microorganisms, including endospores). Inanimate object that has not been subjected to a sterilization process the outside wrapping of a package containing a sterile item a person who has not prepared to enter the sterile field (syn: nonsterile). Procedures carried out for the destruction of pathogens at the end of the surgical procedure in the OR or other areas of patient contact (e.g., postanesthesia care unit, intensive care unit, nursing unit). Methods by which contamination with microorganisms is prevented to maintain sterility throughout the surgical procedure. This area includes all furniture covered with sterile drapes and all personnel who are properly attired in sterile garb. Procedures followed to protect personnel from contact with the blood and body fluids of all patients (formerly referred to as universal precautions).įree of living microorganisms, including all spores.Īrea around the site of incision into tissue or site of introduction of an instrument into a body orifice that has been prepared for the use of sterile supplies and equipment. The circulating nurse must be aware of closeness to the sterile field and the appropriate means to control environmental contaminants. This includes the height of scrubbed team members in relation to each other and the sterile field. Severe toxic febrile state resulting from infection with pyogenic microorganisms, with or without associated septicemia.Īn awareness of sterile, unsterile, clean, and contaminated areas and their proximity to each other. They can invade healthy tissue through some power of their own or can injure tissue by a toxin they produce.

Microorganisms that cause infectious disease. Producing or capable of producing disease. Special precautions taken to prevent the transmission of microorganisms from specific body substances. Inanimate object that may be contaminated with infectious organisms and that serves to transmit disease.

Transmission of microorganisms from patient to patient and from inanimate objects to patients and vice versa.Ĭleaning and disinfecting or sterilizing processes carried out to make contaminated items safe to handle.Ĭhemical or mechanical destruction of most pathogens rendering an object safe to handle. Person who has potentially pathogenic microorganisms on or in his or her body and disperses them into the environment without becoming ill from the pathogen. Barriers include attire of personnel, drapes over furniture and patients, packaging of supplies, and filters in ventilating system. Material used to reduce or inhibit the migration or transmission of microorganisms in the environment. Methods by which contamination with microorganisms is prevented (alternate term: aseptic practice, to maintain asepsis). They are used on skin and tissue to arrest the growth of endogenous microorganisms (resident flora), and they must not destroy tissue.Ībsence of microorganisms that cause disease freedom from infection exclusion of microorganisms. Inorganic chemical compounds that combat sepsis by inhibiting the growth of microorganisms without necessarily killing them. Prevention of sepsis by the exclusion, destruction, or inhibition of growth or multiplication of microorganisms from body tissues and fluids. Dispersion of fine mist, droplets, or particulate matter into air (vt: aerosolize, to become airborne).
