|
- The following slides will show you the typical stages of any surgical
patient at Four Paws Animal Hospital & Wellness Center.
- In this example, “Lupa” is having her “cherry eye” fixed.
|
|
2
|
- All pets are placed in our ICU cages on arrival. These cages are in a
centralized area where the pet can be closely monitored.
|
|
3
|
- Even though your pet has already been examined at it’s pre-surgical
appointment, we check them again the morning of the surgery. We are
evaluating their heart, lungs, temperature, and looking for any signs of
illness.
|
|
4
|
- After their exam is completed, we administer drugs which help calm your
pet to make sure they are not anxious. At this stage we also start pain
medication, because pain medication is much more effective if it is
started before the surgery begins. Pain control is a high priority at
our hospital, and our surgical patients are no exception.
|
|
5
|
- IV catheters are inserted after the sedatives have had a chance to take
effect.
- A spot on the leg (usually a front leg) is shaved.
|
|
6
|
- The skin is then cleaned with a
surgical scrub multiple times.
|
|
7
|
- The catheter is inserted into the vein and a bag of fluids is attached.
- This catheter provides easy access to a vein in case any emergency drugs
are needed, and the fluids help regulate the pet’s blood pressure. Low
blood pressure is one of the most common complications under anesthesia,
so this is a very important step. This is not standard practice at all
hospitals.
|
|
8
|
- Once the catheter is in place,
drugs are administered that will anesthetize the pet
|
|
9
|
- As soon as the pet is asleep, a tube is inserted into their windpipe
(trachea) that helps them breathe.
|
|
10
|
- One end of this tube is attached to the anesthetic machine that delivers
a continuous supply of oxygen and anesthetic gases.
|
|
11
|
- Because Lupa’s eyes stay open while she is anesthetized, and she is
unable to blink, we always apply a lubricating ointment to keep the eyes
moist and prevent any damage to the cornea.
|
|
12
|
- The area that is to have surgery is then shaved, and cleaned multiple
times with surgical scrub.
|
|
13
|
- This dedicated room contains a heated surgery table, optional surgical
laser, centralized oxygen, and a waste anesthetic gas scavenging system.
This is a picture taken on a day when we are not having surgery.
|
|
14
|
|
|
15
|
- Once all the non-sterile
procedures are completed, the pet is then transferred to the surgical
suite.
|
|
16
|
- A clip is placed on the tongue
to monitor the oxygenation of the blood. The technician is measuring how
far she will need to insert the esophageal probe (seen here in white) by
holding it up against the outside of the body to the level of the heart.
|
|
17
|
- The esophageal probe is then
slid down the throat. It measures
heart rate, respiratory rate, core body temperature, and provides the
ECG tracing which allows us to monitor the electrical activity of the
heart.
|
|
18
|
- This is the display on the computer monitor of the pet’s vitals. All the
information is recorded so it can be kept with the patient’s medical
record.
|
|
19
|
- Now that the patient is hooked up to the anesthetic monitoring
equipment, the assistant gets her first of many readings of the
patient’s blood pressure.
|
|
20
|
- One last scrub is done on the surgical site to make sure the area is
completely sterile.
- (In Lupa’s case this was not necessary, because it is impossible for
ocular surgeries to be completely sterile.)
|
|
21
|
- All of the instruments, suture material, and other supplies used are
prepared and kept in a sterile manner to help prevent any infections in
your pet.
|
|
22
|
- The doctor wears a cap, mask,
and gloves to ensure the surgical field remains sterile.
- (For this particular surgery a
sterile surgical gown was not necessary.)
|
|
23
|
- When the surgical laser is used, this instrument replaces a scalpel
blade for any cutting that is required.
- The laser cuts and cauterizes at the same time, sealing off smaller
blood vessels and nerve endings. This translates into less bleeding and
therefore less post-operative swelling. Less swelling and sealed nerve
endings mean less pain.
|
|
24
|
- While the doctor is performing
surgery, our licensed technician is dedicated to continuously monitoring
the patient. She periodically does manual measurements of what the
anesthetic monitoring equipment is telling us, to make sure it is
accurate. She also listens to the patient’s heart and lungs and checks
their blood pressure.
|
|
25
|
- Once the surgery is completed, we stop the anesthesia and allow the
patient to wake up. When they are sufficiently awake, all the monitoring
equipment is removed and the endotracheal tube is taken out of their
airway.
|
|
26
|
- Next the patient is moved into the ICU area for recovery.
|
|
27
|
- These cages have heated floors, and are located in a centralized area so
that your pet can be closely monitored while they finish waking up.
|
|
28
|
- The final step is for the technician and doctor to make notes in the
medical record regarding your pet’s surgery and anesthesia. The
technician then prepares all medications that the doctor wants sent home
with the pet. She also gets ready the printed surgical discharge
instructions which will be reviewed with you at your surgical discharge
appointment.
|
|
29
|
- Feel free to ask to see our surgical facilities for yourself. We would
also be happy to review with you the particulars of your pet’s surgical
procedure.
- Our priority is to make sure your pet is well cared for, and that we
have answered all your questions and concerns.
- Hopefully this virtual surgical tour has helped you to understand what
your pet’s surgery will be like.
