Selection and Preparation of the Surgical Area Flashcards
This room should be close, but not adjacent, to the surgery room. The surgical patients are anesthetized and prepared for surgery in this room. The equipment kept in the preparation room will include drugs used for anesthesia and materials needed to prepare the patient. This room should always be clean and tidy
Preparation Room
When performing surgeries on rodents, this type of sterilizer may be used in between animals when doing more than one.
hot bead sterilizer
options available to sterilize surgical equipment and supplies:
- Autoclave
- Ethylene oxide
- Cold sterilant solutions
- Hot bead sterilizer
- Pre-sterilized items
- Implanted Items
Relies on pressurized steam, is extremely reliable, and cost effective. However, instruments must be durable (e.g., stainless steel) and the process is relatively slow, from 15 to 60 minutes. Instruments are typically wrapped or sealed in packs that are opened as needed on the day of surgery
Autoclave
Autoclave time requirement
15 to 60 minutes
A gaseous sterilant that requires specialized containment equipment.
Ethylene oxide
Ethylene oxide
This is a good sterilization method for supplies that cannot tolerate high heat such as plastics and catheters.
Ethylene oxide
It is more costly than autoclaving and typically is performed overnight
Ethylene oxide
Cold sterilant solutions
hypochlorite, glutaraldehyde
Cold sterilant solutions contact time
15 - 60 minutes
have prolonged contact time (15 - 60 minutes) to sterilize surgical equipment. In addition, the instruments must be rinsed completely with a sterile solution like saline to prevent tissue irritation.
Cold sterilant solutions
This device is a small tabletop unit, approximately 6 x 6 x 8 inches. The appliance heats a small container of Pyrex beads to approximately 250 C and can sterilize the tips of metal surgical instruments in 10-20 seconds.
Hot bead sterilizer
Hot bead sterilizer contact time
10-20 seconds
. It is very useful for sterilizing instruments between rodents when performing surgeries on multiple animals.
Hot bead sterilizer
Many instruments and supplies can be purchased in sterilized packaging. Such items must be used prior to the label expiration date.
Pre-sterilized items -
Special consideration needs to be made for items that will be implanted (i.e. left in the animal after surgery is completed). Many of these items are “sensitive and/or fragile” and can be difficult to sterilize. Possibilities include use of ultra-short autoclave cycle, ethylene oxide, or use of a cold sterilant. Note: Use of alcohol alone is not a sterilant.
Implanted Items
If the surgery is elective the animal should be admitted to the hospital ________ hours prior to the operation
24-hours
Food should be withheld on the day of surgery and ______ hours fasting for gastro-intestinal operation.
24 hours
Hair should be removed from the surgical site, preferably with electric clippers (# ______ blade) or depilatory rather than a razor.
40 blade
Position for surgery in the perineal area (lying on its chest)
Sternal recumbency
Position for surgery in the ventral parts of the abdomen (e.g. ventral midline laparotomy)
Dorsal recumbency
Position for the surgery of the dorsal parts of the animal (e.g. thoracotomy).
Ventral recumbency
Position for the surgery of the right lateral side of the animal.
Left lateral recumbency
