Flashcards in Tech Notes - Chapter 30 Deck (35):

Name some purposes for using surgical instruments.

Each instrument is designed for a specific purpose, such as:


What do vet techs working with lasers have to be mindful of?

All vet techs working with lasers must be trained to take important safety measures each and every time a laser is used in the OR. In addition, they must make use of the emergency shutoff button, if an emergency develops during an operation.


Name some uses for scissors.

Scissors are specifically designed for many purposes, incl. dissecting tissue and cutting suture or bandage materials.
Each pair of scissors should be used only for its intended purpose.


What are needle holders designed to do?

Needle holders are designed for handling the suture needle and performing instrument suture ties.


What are thumb forceps used for?

Thumb forceps are commonly used in the surgeon's nondominant hand to hold tissues while dissecting or suturing.


How do tissue forceps clamp and hold tissues?

Tissue forceps use a self-locking mechanism to clamp and hold tissues.


What are hemostatic forceps used for?

Hemostatic forceps are used to clamp, crush, and hold blood vessels with a self-locking mechanism.


What do you use to retract tissues?

Retractors rather than hands are used to retract tissues and provide good visibility of the surgical site.


Why is accordion folding of drapes preferred?

Accordion folding of drapes allows easy unfolding and placement on the patient.


During autoclaving, what position should hinged or box locked instruments remain in?

Instruments with hinges or box locks should remain in the unlocked position during autoclaving.


What is the safe minimum standard for autoclave sterilization?

The safe minimum standard for autoclave sterilization is 121*C (250*F) for 13 minutes!


What should you keep in mind when having packs cool down?

Packs should be allowed to cool slowly to reduce condensation formation.


What are the four types of sterilization indicators?

1. Autoclave tape
2. Melting pellet glass
3. Culture tests
4. Chemical sterilization indicators


With what and why is ethylene oxide being replaced?

Because of the high toxicity of ethylene oxide, it is being replaced by hydrogen peroxide gas plasma sterilization.


Name the two most commonly used antiseptic agents.

The two most commonly used antiseptic agents are:
1. Povidone-iodine
2. Chlorhexidine


What is chlorhexidine?

Chlorhexidine is an effective antimicrobial agent with rapid onset and long residual activity.


What items should never be steam sterilized?

The arthroscope or laparoscope, fiberoptic light cable, and the camera should never be steam sterilized.


What is glutaraldehyde?

Glutaraldehyde is a disinfectant for medical and dental equipment.
Glutaraldehyde is carcinogenic, causes a chemical synovitis, and is injurious to chondrocytes.


How often should the OR be cleaned?

Daily and weekly cleaning schedules should be established for the OR.


How often should the surgical site be scrubbed and rinsed?

It is generally recommended that the surgical site be scrubbed and rinsed at least 3 times (or until the gauze comes back clean).


What is the contact time for povidone-iodine when used as a sterile scrub?

The sterile scrub should provide at least 5 minutes of contact time for povidone-iodine.


What is often applied to the skin after the scrubs?

An antiseptic solution is often applied to the skin after the scrubs.


Benefits of the one-step preps:

One-step preps are:
- easy to apply
- much faster than traditional scrubbing techniques
- effective for antimicrobial kill
- provide rapid onset
- have a long residual effect


What position is commonly used for abdominal surgical procedures?

The dorsal recumbent position is commonly used for abdominal surgical procedures.


Who is in charge of making sure that all personnel in the surgery suite are following protocol?

The surgical nurse should take charge to make sure that all personnel in the surgery suite are following protocol.


What should everyone entering the OR be wearing?

Anyone entering the OR should wear:
- cap
- mask
- booties
- scrub suit


Describe the surgical hand scrub!

The surgical hand scrub requires that all surfaces of the fingers, hand, and forearm be scrubbed.
Skin-soap contact time should last 5 minutes.


Benefits of waterless hand antiseptics:

Waterless hand antiseptics are:
- easy to apply
- faster than traditional hand-scrubbing techniques
- effective against microorganisms
- nonirritating to the skin


Name the two methods of gloving yourself!

1. Closed gloving
2. Open gloving


What is assisted gloving?

Assisted gloving requires the help of a sterile assistant.


No-nos for nonsterile personnel!

Nonsterile personnel should not lean over or reach across sterile fields.


What is the sterile region of a gown after gowning and gloving?

After gowning and gloving, the sterile region is the front of the gown between the waist and just below the shoulders. Gown sleeves are also sterile, but not the back.


Optimal draping approach

The optimal approach to draping includes isolating the surgical site with two layers of drapes:
(1) four quarter drapes
(2) a large drape that covers the entire animal and the instrument table
Additional incisional drapes or antiseptic-impregnated adhesive drapes can be added to further improve aseptic technique.


Which way should the pack face while opening it?

While opening a pack, make sure that the opening faces away from you.


What is strike-through?

If drapes or gowns (especially those made of cloth) become wet with saline or blood, they may no longer be impermeable to bacteria and are said to have strike-through.
