- Procedures involving animals will avoid or minimize discomfort, distress
and pain
|

|
- The Principal Investigator must have considered alternatives to
procedures that cause more than momentary or slight pain
- The experiment must be prepared in consultation with the attending
veterinarian with the appropriate use of sedatives, analgesics or
anesthetics
- Experiments must not be performed using muscle paralyzing agents without
adequate anesthesia Animals that would otherwise experience severe unrelieved pain or distress must
be euthanized.
|
|
4
|
- Research personnel must be qualified and trained in the procedures they
perform
- All surgery must be accompanied by appropriate pre-operative and
post-operative care.
- All survival surgery must be performed using aseptic technique
- No animal may be used in more than one major operative procedure unless
it is scientifically justified or required for the health of the animal
|
|
5
|
- All proposed procedures and animal care must be contained within an
approved and active IACUC procotol.
- Training and expertise of investigatory staff is assessed at the time of
protocol review.
|
|
6
|
- Veterinary Services can provide training in animal handling, restraint,
anesthesia, surgical asepsis and post op care
- Veterinary Services may also be contracted to perform experimental
procedures
|

- Aseptic technique required

- Hair removal and disinfection of the operative site
- Use of sterilized instruments (alcohol soak not acceptable)

- Call the Veterinary Technicians Office (x2507) to schedule a surgery day
and time.
- Submit a Procedure Data Sheet to Veterinary Technicians Office, EB12A,
as far in advance as possible but no less than 48 hours prior to
surgery.
- Procedure data sheets are available at http://labanimals.cwru.edu, the
Vet Tech Office, EB12A or the ARC Office, TB03A.

15
|
- Enter initial data in the anesthetic recovery record.
- Aseptically place an IV catheter.
- Intraoperative fluid requirement is 10-20 ml/kg/hr of sterile IV fluid
such as Lactated Ringer’s Solution, 0.9% NaCl or 5% dextrose
- IV lines may be omitted for rabbit surgeries of short duration
|
|
16
|
- Administer anesthesia IM or IV to
effect
- Follow quickly with endotracheal intubation
- Muscle relaxants are not needed for animal intubation
- Depending on the species or surgical procedure, intubation may be
omitted
|
|
17
|
- Clip the fur from an area twice as large as the expected surgical site.
- A preliminary surgical scrub may be done at this time
- Move the animal to the operating room
- Place the animal on a drape covering a water circulating heating pad on
the surgical table
|
|
18
|
- Sterile equipment and gloves are used
- The scrubbed area is twice as large as the expected surgical field
- Use a 4x4 pad and betadine or chlorhexidine as a surgical scrub
|
|
19
|
- Scrub using circular motion which begins in the center of the field and
widens to the edges.
- Discard the 4x4 sponge.
- Repeat 6 times alternating betadine scrub and alcohol
- Spray the scrubbed area with betadine solution
|
|

|
- Wear a scrub suit or roll sleeves above elbows

|
|
25
|
- Follow sound principles of surgical technique
- Gentle handling of tissues
- Keep exposed tissues moist with sterile saline
- Maintain the sterility of the surgical field
- Keep track of small pieces of equipment and surgical sponges
- All survival procedures will be monitored initially by a Veterinary
Technician until proficiency has been assessed
|
|
26
|
- Unless prior arrangements are made with Veterinary Services, all post
procedural monitoring is the responsibility of the investigatory staff.
|
|
27
|
- Monitoring is continuous until extubation
- Then, every 30 minutes until the animal is sternal
|
|
28
|
- Daily until sutures are removed and animal has stabilized
- Use SOAP format
- Subjective
- Objective
- Assessment
- Plan
|
|
29
|
- Subjective:
- Appears painful, depressed
- Objective:
- Temp 101oF, incision clean and intact, minimal swelling, Not
eating much. Normal color,
hydration
- Assessment:
- No sign of infection.
Post-operative pain
- Plan:
- Give buprenorphine, tempt to eat, monitor weight, continue observation
|
|
30
|
- If a procedure is known to be painful for humans, assume it is equally
painful for animals
- Know the signs of pain in the species you work with
- Most lab animal species do not demonstrate signs of pain well
- Preemptive analgesia for all animals is recommended http://iacuc.cwru.edu/policy/analganesth.html
- The ARC veterinarians can recommend appropriate methods of providing
analgesia
|
|
31
|
- Unless sutures are buried or absorbable, suture and/or surgical staple
removal for all species must be done by 14 days post surgery.
