Chapter 30 - Key terms Flashcards
Asepsis?
condition of sterility wherein no living organisms are present
Aseptic technique?
methods used to prevent contamination of a surgical site or wound by disease-producing organisms
Assisted gloving?
method on putting on sterile gloves in which a sterile, gloved assistant holds the glove open to allow the surgeon to advance his or her hand into the glove without touching the outside
Box lock?
hinged part of a needle holder, tissue forceps, or hemostatic forceps
Chemical sterilization?
Use of liquid or gas to sterilize surgical materials.
Closed gloving?
method of putting on sterile gloves in which the hands are kept hidden within the sleeves of a sterile gown during gloving
Flash sterilization?
Emergency sterilization in which the instrument is placed unwrapped in an autoclave and is taken directly to surgery after sterilization.
Gas sterilization?
use of chemical vapors to sterilize surgical materials and instruments that cannot withstand the high temperatures associated with steam sterilization in autoclaves (ethylene oxide -most commonly used gas)
Incise draping?
a sterile, adherent, plastic surgical drape -often impregnated with an antiseptic. The drape is incised along with the skin.
Ingress port?
port on a tubular instrument used to infuse a solution into a cavity, such as a joint
Insufflate?
to pump a gas or medicinal substance into a body cavity
Joule?
unit of energy or work. The amount of work required or energy needed to produce 1 watt of power for 1 second
Obturator?
stylus or removable plug used during insertion of a tubular instrument
One-step prep?
alcohol-based solutions containing other antiseptics that form a film when painted on the skin - provide rapid onset of antiseptic effect and a long residual effect
Open gloving?
method of putting on sterile gloves when the person is not wearing a sterile gown or when the hands are protruding through the ends of the gown sleeves
Osteochondral fragments?
fracture involving the articular cartilage and underlying bone
Paralumbar fossa?
depression in the dorsocaudal abdominal body wall of quadrupeds bordered by the costal processes of the lumbar vertebrae, the last thoracic rub, and the tuber coxae
Peritoneal lining?
a thin transparent membrane (serosa) that lines the peritoneal cavity, also called the parietal peritoneum
Physical sterilization?
use of filtration, radiation, and heat applied to medical products.
Plume?
smoke created from laser application on tissue
Prosthesis?
synthetic material used to replace some tissue or part of the body
Ratchet?
part of an instrument- usually located near the rings or handles - allows the instrument to be maintained in one position after it has grasped or retracted the tissue
Recumbency?
lying down
Residual activity?
continued bactericidal activity that persists after antiseptic or disinfectant has been applied
Scrub in?
the process of disinfecting the hands and donning sterile gown and gloves to participate in a sterile procedure
Scrub suit?
shirt and pants worn into the operating room - usually made of lint-free cotton or polyester material
Sterile field?
an area that has been prepared for the use of sterile equipment
Sterile technique?
creating a sterile field and working within it by not contaminating it with nonsterile objects
Strike-through?
when fluid penetrates a surgical drape or gown, it creates a pathway by which organisms can invade the sterile field
Subchondral bone?
the bone that lies just beneath joint cartilage
Triangulation?
technique used in laparoscopic and arthroscopic surgery that establishes two reference points - one using the scope and the other the surgical hand instrument - to target a third point, the surgical site
Glutaraldehyde?
a liquid that is commonly used to sterilize surgical instruments
When is ethylene oxide and hydrogen peroxide used?
when needing to sterilize by vaporization of EO and HP, delicate equipment, instruments, and plastic items that cannot tolerate the high temperatures, pressures, and steam (autoclaving)
Filtration is often used to sterilize?
pharmaceuticals
Radiation is used to sterilize?
packaged products such as sterile bandaging material
Heat is used to sterilize?
surgical instruments and materials that cannot withstand the high temperatures, pressure, and heat of autoclaving
What areas are included in the sterile field?
the area around the wound, incision site or body orifice into which an instrument or catheter will be passed, the area covered by sterile drapes and the sterile region of properly attired personnel
How does triangulation help the surgeon in surgery?
enables the surgeon to visualize the site of interest while at the same time manipulating surgical instruments inside a body cavity to make surgical corrections
