CST Chapter 10 The principles and practice of aseptic technique
Terms in this set (85)
Chemical agents approved for use on the skin that inhibit the growth and reproduction of microorganisms.
The absence of pathogenic microorganisms on an animate surface or on body tissue. Literally, asepsis means "without infection", whereas sepsis literally means "with infection". In surgery, asepsis is a state of minimal or zero pathogens. Asepsis is the goal of many surgical practices.
Methods or practices in health care that reduce infection.
The barrier formed by the action of an antiseptic; it not only reduces the number of microorganisms on a surface, but also prevents recolonization (regrowth) for a limited period.
Containment and confinement
A foundational concept of aseptic technique in which sterile and nonsterile surfaces are separated by physical barriers or distance (space).
The consequence of physical contact between a sterile surface and a nonsterile surface in surgery resulting in the potential or actual transfer of microbes from one surface to another.
Wearing two pairs of gloves, one over the other, to reduce the risk of contamination as a result of glove failure or puncture.
Contamination of a large area of tissue by a highly infective source.
A specific technique used to remove soil, debris, and dead cells from the hands. Hand washing with an antiseptic also reduces the number of microorganisms on the skin.
Non sterile personnel
In surgery, team members who remain outside the boundary of the sterile field and do not come in direct contact with sterile equipment, sterile areas, or the surgical wound. The circulator, anesthesia care provider, and radiographic technician are examples of nonsterile team members.
In surgery, a barrier that separates a sterile surface from a nonsterile surface. Examples are sterile surgical gloves, gowns, and drapes. A physical barrier, such as a clean surgical cap, prevents a bacteria-laden surface, such as the hair, from shedding microorganisms.
Microorganisms are normally present in specific tissues. Resident flora are necessary to the regular function of these tissues or structures. Also called normal flora.
The scrubbed surgical technologist or nurse assisting in surgery. Also refers to the surgical hand scrub performed before surgery.
In surgery, members of the surgical team who work within the sterile field. Also called sterile personnel.
Any objects that can penetrate the skin and have the potential to cause injury and infection, including but not limited to needles, scalpels, broken glass, and exposed ends of dental wires.
An area that includes the draped patient, all sterile tables, and sterile equipment in the immediate area of the patient. The patient is the center of the sterile field.
Any item or medical device that has been exposed to a process that destroys all microbes, including spores.
A state in which an inanimate or animate surface harbors absolutely no viable microorganisms.
An event in which fluid from a nonsterile surface penetrates the protective wrapper of a sterile item, causing it to become contaminated.
In surgery, the ethical motivation to practice excellent aseptic technique to protect the patient from infection. Surgical conscience implies that the professional practices excellent technique regardless of whether others are observing.
Surgical hand scrub
A specific technique for washing the hands before donning a surgical gown and gloves before surgery. The scrub is performed with timed or counted strokes using detergent-based antiseptic. The surgical hand scrub is designed to remove dirt, oils, and transient microorganisms and reduce the number of resident microorganisms.
Surgical hand rub
The systematic application of antiseptic foam or gel on the hands before gowning and gloving for a sterile procedure. The surgical handrub may be used as an alternative to the traditional hand scrub under certain conditions.
Surgical site infection (SSI)
Postoperative infection of the surgical wound. The goal of surgical skin preparation is to prevent postoperative wound infection.
Microorganisms that do not normally reside in the tissue of an individual. Transient microorganisms are acquired through skin contact with an animate or inanimate source colonized by microbes. Transient flora may be removed by routine methods of skin cleaning.
What are the four objective of aseptic technique discussed in the text?
d. elimination of microorganisms
Where is the sterile field? What is the center of this area?
The sterile field is the physical area starting with the surgical incision (patient) at the center. It extends to include patient drapes, sterile instrument tables and any draped equipment.
The methods used to achieve the goal of asepsis are called _______________.
"doing and thinking"
Items exposed (opened) to the surgical field are considered ___________ after they have been exposed to the air or to a patient's tissue.
Sterile objects are contained or confined to avoid contact with ____________ objects.
If any doubt exists about the sterility of an item, it should be considered _______________.
Describe when a surgical technologist might choose to use a bouffant's cap a surgeon's cap?
The surgical technologist wears bouffant caps to reduce contamination of the surgical field by loose hair and dandruff from the scalp. The scalp and hair are a rich source of Staphylococcus aureus and other bacteria, which proliferate under surgical caps. Logically, using the cap during any and all surgeries is ideal.
The primary purpose of shoe covers is to ________________.
protect the wearer and prevent the tracking of blood and other body fluids outside the surgical suite.
____________, ____________, and ______________ are the three types of hand hygiene practiced in the operating room.
The routine hand wash, the handrub with antiseptic, and the traditional surgical scrub.
Masks must be worn in all restricted areas of the operating room. They should not be worn dangling around the neck at any time because ________________.
they present a significant source of contamination.
Home laundered head caps are not sanctioned by any infection control agency because ____________________
they are a potential source of contamination. People often put them into lockers or wash them after several days.
The surgical hand rub is performed in place of a traditional surgical scrub except when ____________________.
the hands and arms are grossly soiled or have come in contact with body fluids.
The traditional surgical scrub is performed in place of the hand rub following __________________.
contamination of the hands or arms by potentially infectious body fluids.
Sterile gowning and gloving takes place immediately after __________________.
preparation of the hands and arms for a surgical procedure.
The sterile towel, gown, and gloves should be opened on a clean surface away from where sterile instruments and other equipment has been opened to prevent ___________________.
A gown should be changed during surgery if _________________.
it is contaminated or penetrated by blood or other fluids.
Double gloving is preferred over single gloving because _______________.
Double gloving has been shown to reduce the risk of glove failure, which increases with surgical time and prolonged handling of tissues and supplies.
Closed gloving technique is used when ________________.
preventing contact between skin and the outside of the sterile glove.
Open gloving technique is used for ________________.
Open gloving is used during sterile procedures that do not require a sterile gown, such as preoperative skin preparation of the patient, assisting in minor skin procedures, catheterization, and when a scrubbed member changes a glove without changing his or her gown.
When gloving another person, you should open the glove, grasp the upper edges and offer it with the palm of the glove facing ______________.
the person you are gloving.
If a surgical team member contaminates their glove during surgery, the circulator will remove it. This is done by offering the contaminated hand with the palm facing _________________.
