How does the veterinary team know when to replace the WAG (waste anesthetic gas) canister?
1. look at granule color
2. discard every 3 months
3. time the hours of anesthesia time
4. weigh canister until it reaches discard weight listed by manufacturer
- weigh canister until it reaches discard weight listed by manufacturer

a. Two
b. Three
c. Four
d. Five
b. Three
What is most likely causing this Capnograph wave form?
1. this is a normal capnograph
2. hypothermic patient
3. obstruction in the breathing circuit
4. intubation of the esophagus
- obstruction in the breathing circuit
What do we flush an IV catheter with every 6 hours when it is not being used for IV fluid administration?
Heparin-saline solution.
We do this to ensure it is still correctly in place within the vein and to prevent clots from forming within the catheter.
Standard protocol is to evaluate the patient’s body temperature a minimum of every ___ hours when an IV catheter is in the patient.
a. 12
b. 24
c. 2
d. 6
d. 6 hours
- Name two possible complications of an intravenous catheter.
- Name a clinical sign indicating each of the complications you listed in the previous question.
- Complications:
- Unsuccessfully delivering IV fluids.
- Bacteria getting into the bloodstream. - Signs:
- Swelling proximal to IV placement due to fluid accumulation in the SQ tissue.
- New fever since placing IV.
Name two possible veins that an intravenous catheter may be placed in a veterinary patient.
Cephalic & Jugular
Name two possible indications for an intravenous catheter.
- To deliver Rx
- Monitor blood pressure
IVC placement steps: (9)
- Wash hands.
- Flush IVC with heparin-saline flush.
- Aseptically open infusion plug.
- Shave & Scrub IVC site.
- Gloves on! - Position non-dominant hand parallel to vein & hold paw.
- Catheter, bevel up, introduced into vein.
- Once flash is achieved, lower angle of IVC to be parallel w/vein. Slowly advance, ensure IVC is still in.
- “Flicking” off of stylet w/fingertip. - Place infusion plug.
- Apply pressure proximal to IVC to slow blood flow. - Flush IVC to ensure patency.
T/F: If a WAG canister no longer gains or loses weight the canister should be replaced.
True
T/F: WAG canisters can sit directly on floors or tables or positioned horizontally
False.
- The bottom vent must be open so the bottom of the canister shouldn’t be obstructed.
- Placed horizontally will result in ineffective use of canister & may leak CO2 (?)
When a new WAG canister is placed, what two things must be documented on the canister?
- Baseline weight
- Date
- What plane of anesthesia is Lexi at?
- Would you change anything about her anesthesia?
- Plane 1
- Light - Turn up anesthesia.
- Possibly give anesthetic drugs to help with waiting for anesthesia to reach patient.
- What plane of anesthesia is Lexi at?
- Would you change anything about her anesthesia?
- Stage III, Plane III
- Too deep - Lower anesthesia, add more O2
- Provide heat supplement
The DVM asks you to fill transmucosal buprenorphine for a patient to go home with. They ask you to fill 0.01mg/kg for each dose. Your patient weighs 16lbs. Buprenorphine comes in a concentration of 0.3mg/mL.
What is the total volume (round to nearest tenths place) you will send home for a patient if they are getting a dose every 12 hours for 7 days?
3.2mL
7.3kg x 0.01mg = 0.073mg/dose
0.07mg / (0.3mg/mL) = 0.23mL/dose
BID for 7 days = 14 doses
0.23mL x 14 doses = 3.22mL total
