Flashcards in Key Terms - Chapter 30 Deck (36):
1

Asepsis

Condition of sterility wherein no living organisms are present.

2

Aseptic technique

Methods used to prevent contamination of a surgical site or wound by disease-producing organisms.

3

Assisted gloving

Method of 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.

4

Box lock

Hinged part of a needle holder, tissue forceps, or hemostatic forceps.

5

Chemical sterilization

Use of liquid or gas to sterilize surgical materials. Glutaraldehyde is a liquid that is commonly used to sterilize surgical instruments. Ethylene oxide and hydrogen peroxide are vaporized to sterilize delicate equipment, instruments, and plastic items that cannot tolerate the high temperatures, pressures, and steam associated with autoclaving.

6

Closed gloving

Method of putting on sterile gloves in which the hands are kept hidden within the sleeves of a sterile gown during gloving.

7

Flash sterilization

Emergency sterilization in which the instrument is placed unwrapped in an autoclave and is taken directly to surgery after sterilization. Recommended exposure is 3 minutes at 131*C (270*F).
It is not recommended as a routine sterilization procedure.

8

Gas sterilization

Use of chemical vapors to sterilize surgical materials and instruments that cannot withstand the high temperatures associated with steam sterilization in autoclaves. The most commonly used chemical gas is ethylene oxide.

9

Incise drape

A sterile, adherent, plastic surgical drape. It is often impregnated with an antiseptic. The drape is incised along with the skin.

10

Ingress port

Port on a tubular instrument used to infuse a solution into a cavity, such as a joint.

11

Insufflate

To pump a gas or medicinal substance into a body cavity.

12

Joule

Unit of energy or work. The amount of work required or energy needed to produce 1 watt of power for 1 second.

13

Obturator

Stylus or removable plug used during insertion of a tubular instrument.

14

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.

15

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.

16

Osteochondral fragments

Fracture involving the articular cartilage and underlying bone.

17

Paralumbar fossa

Depression in the dorsocaudal abdominal body wall of quadrupeds bordered by the costal processes of the lumbar vertebrae, the last thoracic rib, and the tuber coxae.

18

Peritoneal lining

A thin transparent membrane (serosa) that lines the peritoneal cavity. It is also called the parietal peritoneum.

19

Physical sterilization

Use of filtration, radiation, and heat applied to medical products. Filtration is often used to sterilize pharmaceuticals, radiation is used to sterilize packaged products, such as sterile bandaging material, and heat is used to sterilize surgical instruments and materials that cannot withstand the high temperatures, pressure and heat of autoclaving.

20

Plume

Smoke created from laser application on tissue.

21

Prosthesis

Synthetic material used to replace some tissue or part of the body.

22

Ratchet

Part of an instrument - usually located near the rings or handles - that allows the instrument to be maintained in one position after it has grasped or retracted the tissue.

23

Recumbency

Lying down.
This adjective indicates which part of the body is on the ground or table. For example, lateral recumbency means that the animal is lying on its side, and dorsal recumbency means that the animal is lying on its back.

24

Residual activity

Continued bactericidal activity that persists after antiseptic or disinfectant has been applied.

25

Scrub-in

The process of disinfecting the hands and donning sterile gown and gloves to participate in a sterile procedure.

26

Scrub suit

Shirt and pants worn into the OR. Usually made of a lint-free cotton or polyester material.

27

Sterile field

An area that has been prepared for the use of sterile equipment. This includes the area around the wound, incision site, or body orifice into which an instrument or catheter will be passed. It also includes the area covered by sterile drapes and the sterile region of properly attired personnel.

28

Sterile technique

Creating a sterile filed and working within it by not contaminating it with nonsterile objects.

29

Strike-through

When fluid penetrates a surgical drape or gown, it creates a pathway by which organisms can invade the sterile field.

30

Subchondral bone

The bone that lies just beneath joint cartilage.

31

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. This 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.

32

Antiseptic

Agent capable of preventing infection by inhibiting the growth of infectious agents. This term is generally applied to living tissue.

33

Autoclave

Sterilizer that uses saturated steam under pressure to achieve high temperatures for sterilization. Minimum exposure to saturated steam is 13 minutes or 121*C (250*F).

34

Disinfectant

Agent that destroys or inhibits microorganisms. Typically refers to inanimate objects.

35

Ethylene oxide

Gas chemical sterilization agent used to sterilize objects that cannot withstand heat. A good exhaust system must be used.

36

Sterilization

Destruction of all microorganisms. This term is generally applied to inanimate objects.
