How risky is it to anesthetize super young pets?

Rosalina, a 3 month old kitten.

Lukas, a 2 month old coyote.

Pup, a 3 WEEK old puppy.

What do these tiny patients have in common? They all needed a broken bone repaired. And they all super young.

Rosalina the kitten had a broken femur (thigh bone).

Lukas the coyote had a fractured humerus (arm).

Pup the puppy had a broken tibia (shin bone).

Their surgery was definitely challenging because of their soft bones. But the biggest challenge is really anesthesia.

Why is the risk of anesthesia in pediatric patients higher than in other patients?

Younger patients are at risk for hypoglycemia (low blood sugar), hypothermia (low temperature) and hypotension (low blood pressure).

Hypoglycemia

Younger patients have very little body reserves on board. So they are at risk for hypoglycemia (low blood sugar).

Patients who are old enough are often fasted at 8 pm the day before anesthesia.

In young puppies and kittens, we can’t do that, precisely to prevent hypoglycemia. Babies are typically allowed a small meal the morning of surgery.

Their blood sugar should then be monitored before, during and after anesthesia. If it’s too low, we can give sugar IV (in the form of dextrose) or by mouth (in the form of Karo syrup).

Hypothermia

Another struggle is keeping very small patients warm. All patients rapidly loose body heat under anesthesia. Super young patients are an even bigger challenge.

Of course, the solutions are well-known: warm air blankets, warm water blankets, IV fluid warmers etc.

These warming devices actually need to be put in action early and systematically to keep your pet safe.

Hypotension

Our pediatric patients may also have trouble with low blood pressure as a side effect of anesthesia.

Low blood pressure can be very dangerous if not corrected. Blood needs to appropriately move through the body to carry oxygen to all vital organs, such as the kidneys.

Decreased oxygen makes just about everything unhappy. It’s so important, that we monitor all of our patients’ vitals, including blood pressure, so changes can be identified early and corrected.

Blood work

Another way to decrease the risk of anesthesia is to run blood work. This helps us ensure that vital organs like the kidneys and the liver are healthy, and your baby can safely go under anesthesia. Of course, this applies to adults as well, and especially to seniors.

If the blood work does uncover an abnormality, it does not necessary mean that surgery will be canceled. However, it will often mean changing the anesthesia medications & postop pain medications used.

One specific thing we look for in young patients is abnormal numbers that could indicate an important condition called a liver shunt.

None of this information should change your mind about doing surgery. What it should do is educate you to make sure you and your vet can come up with the best plan for your baby, with the safest anesthesia and the smoothest recovery possible.

Hypoglycemia, hypothermia and hypotension are pretty straightforward to prevent when you are working with an experienced team. So don’t be shy about asking questions, so your super young pet is safe during anesthesia and surgery.

Who on earth wants surgery on their 23 year old cat?

I recently repaired a fracture on a 23 year old cat. Some of my nurses aren’t even that old! It’s a true story with a very happy ending.

Basil, the 23 year old cat, had a broken tibia. The shin bone was broken in 3 main pieces. He went to the local ER, where his owner was told that he was too old and should be put to sleep.

That did not sit well with Basil’s owner. He may be 23 years old, but he was healthy otherwise, so why end his life? His owner contacted me regarding Basil’s situation. We agreed that it was ethical to perform surgery on him, since he was healthy otherwise, and we scheduled him for surgery.

Fixing the shattered bone required 1 pin, 1 plate, 4 wires, and 9 screws to repair! A bone graft was added to speed up healing. Surgery went well and sweet Basil recovered smoothly under the close supervision of his nurses.

At home, he was strictly confined for 8 weeks. At suture removal, after only 2 weeks, he surprised everybody by walking around using the leg very well.

And after 8 weeks, follow up X-rays showed that the bone had healed nicely and we could start to increase Basil’s activity.

And after one more month of that, Basil returned to his normal Grandpa life.

So what’s the moral of this story?

As I always say, “Age is not a disease.”

A few conditions need to be met for surgery to be a valid option in my opinion:

. The patient should be reasonably healthy

. The condition should be fixable.

. Quality of life should be good after surgery.

. The owner should be 100% on board.

Two months after surgery, Basil’s owner writes: “My sweet 23 year old cat is finally back on the couch with me. He is getting giant hugs. He’s really doing great. I really have no words to thank you enough.”

I don’t see why we should deny help to a patient who fulfills these criteria.

Basil’s owner certainly felt that way, and I am sure Basil did as well…

E Collars and Your Pet- Cone of Shame or Best Friend?

Ah, the dreaded “cone of shame…”

After any surgery, we strive to send your pet home with an incision that looks as nice as possible. The plastic cone or E collar (short for Elizabethan collar) was created to prevent licking. Without it, licking or chewing can cause irritation and discomfort.

At best, that may leave a hairless, discolored, ugly scar – for life.

Or it could lead to an open incision, that needs another surgery to close it up.

At worst, it can cause a serious infection.

WARNING: some pictures below might be disturbing to some sensitive readers.

Despite the stubborn urban legend that animal saliva speeds up healing, licking an incision is a sure way to slow down healing. The tongue, especially in cats, is so rough, that it can destroy healing tissue, and therefore delay healing.

Depending on the particular pet or level of discomfort, licking can lead to nibbling and chewing, especially when nobody is around to watch or distract them.

Pets have an amazing inherited skill, which allows them to chew up twenty stitches or staples in less than two seconds flat. By the time you realize it, it’s too late!

Below is an example of a dog who was caught in the act. She went home with a cone that is too short, and does not prevent reaching the incision. Clearly, the correct fit is critical.

I cannot begin to count how many times pet owners have asked me if their pet really has to wear an E collar.

And I cannot begin to tell you how many clients thought their pet was different, or well-behaved, or well-trained, or smarter, and didn’t need a cone.

Or how many pet owners were in tears after their pet chewed the incision open after they removed the cone “for only 5 minutes” or “just to give him a break” or “because she looked so sad.”

Below is a (mild) example of what happens when a pet licks the incision.

I cannot begin to add up all the extra money owners have paid to fix open incisions at their vet or the emergency clinic.

And I cannot tell you how many clients swear that they will not leave their pet’s side for 2 or 3 weeks. Meanwhile, I’m pretty convinced that these clients will need to sleep, or go to the bathroom, or get a bite to eat. There is no such thing as 24/7 supervision with a pet!

Depending on how bad the damage is, treatment may require rinsing the open area, cutting out damaged tissue and re-stitching the entire incision. For a little bit of perceived freedom from the evil cone, clients sometimes end up spending more money in anesthesia, surgery and antibiotics to fix an entirely avoidable problem, not to mention the discomfort the pet goes through – and a longer recovery. And ironically, then the pet needs a cone for even longer!

Below is another (mild) example of what happens when a pet licks the incision.

Leaving the E collar on at all times is the best way to get your pet used to it. If you feel bad for your pet and take the cone off, then put it back on when you leave, your pet may take it as a punishment and may try to remove or destroy it.

Patients can absolutely eat, drink, walk, pee, poop, and sleep with a cone on. In fact, the stricter you are with the cone, the quicker they will get used to it. In addition, pets do not hold grudges, so they will not be mad at you for being strict with the rules.

Collars are not to “shame” pets or annoy owners, they are essential for quicker and better healing of the incision. Call it a necessary evil or a cheap insurance policy. Next time your vet recommends an E collar or a similar device, please follow their advice. It truly is in your pet’s best interest.

Moral of the story?

The plastic cone is your pet’s best friend.

Any surgery has complications. Some are not predictable. Licking an incision is totally avoidable. We know how to prevent that. Please trust us, and please be part of the solution.

Your pet, in the end, will thank you for it.

What about alternatives to the plastic cone?

Marketers spend a fortune trying to convince pet owners that their alternative is better than the hard plastic cone.

There are soft cones, hard cylinders, foam “donuts,” inflatable “donuts,” various covers and sleeves and more.

As a surgeon, I have witnessed what seems like every conceivable complication.

Experience has shown me that these options are not as fool-proof as the standard plastic cone.

A stubborn or itchy pet will lick around a donut or soft collar, we see it all the time!

Bitter Apple or similar product may be placed around the incision – not directly on it. However, this does not deter some pets at all. Some actually love the taste!

So again, the hard plastic cone is your pet’s best friend… and the cheapest insurance policy against licking.

10 deadly sins of untreated ACL tears

Pet owners sometimes ask what would happen if we didn’t address a torn anterior cruciate ligament (ACL). Dr. Google and random people will suggest conservative treatment as a perfectly valid option.

A non-surgeon colleague even wrote elsewhere that since people often don’t need surgery for an ACL tear, then we shouldn’t need it in dogs. Respectfully, this shows a basic misunderstanding of the differences in functional anatomy between dogs and humans. Let’s mention two:

. Humans are straight legged. Dogs always have their knees flexed when standing.

. The human tibial plateau angle is somewhere around 7 degrees. Dogs’ tibial plateau angles vary from around 20 to over 60 degrees, with a back-of-the-envelope average of 24 to 28 degrees in most of my tibial plateau leveling osteotomy (TPLO) patients.

How many reasonable, objective, ethical, honest reasons can you find to recommend conservative treatment as opposed to surgery?

Here are 10 consequences of untreated ACL tears:

1. Pain

Patients with a torn ACL are in pain.

Please remember that limping or favoring or babying a leg = pain.

Pets are not crazy! Holding the affected leg up or limping hurts less than putting full weight on the leg.

When the tear becomes older, pain might subside to some degree, but it stills hurts.

Another reason patients are limping is because the knee is unstable or wobbly.

2. Arthritis

We routinely notice during surgery that patients with long-standing (chronic) ACL tears have more arthritis than patients with a recent injury. This, in turn, leads to pain.

Patients with partial tears typically have less arthritis than patients with complete tears. Recent tears also regularly lead to less arthritis than older (chronic) tears.

Therefore, the sooner we perform the surgery, the better for the patient.

Multiple bone spurs (green arrow) and destroyed cartilage (blue arrow)

3. Scar tissue

Scar tissue is what we rely on after conservative treatment for an ACL tear. Experience proves that scar tissue alone is not enough to provide good function, at least in medium- and large-breed dogs.

Scar tissue is manifested by what we call the “medial buttress,” which can be a very prominent bulge inside a pet’s knee.

Medial Buttress

In turn, scar tissue leads to our next point.

4. Decreased range of motion

A long-term consequence of arthritis and scar tissue is a decreased range of motion of the knee.

Patients with older (chronic) ACL tears commonly experience a decreased range of motion. This might not matter much to a couch potato, but it will affect the performance of an active family pet or a working dog.

5. Muscle atrophy

Patients who favor a hind leg classically show various degrees of muscle atrophy because of poor use of the leg.

This can be assessed easily by measuring the circumference of the thigh with a simple tape measure.

6. Exercise intolerance

Obviously, a family pet or working dog will have a tough time running around with a sore knee.

Dogs with a torn ACL are reluctant to play or go for walks. Exercise intolerance or poor athletic performance classically leads to weight gain, because these pets often receive the same amount of food (and sometimes more, along with more treats).

7. Weight gain

A consequence of many of the above changes is decreased activity, which invariably causes weight gain.

This is a common observation in ACL patients. Unless you decrease your pet’s food intake to match the decrease in activity, weight gain is inevitable.

8. Opposite ACL tear

Arguably, weight shifting may lead to a tear of the opposite ACL. While this might be manageable in a yorkie or a cocker, it becomes a much bigger problem with a Labrador or a mastiff. Helping a 100 lb dog who has both ACLs torn at the same time is not easy!

9. Tear of the meniscus

Instability in the knee can lead to a tear of the meniscus (see picture below), which is a pad of cartilage in the knee. This can cause even more pain.

On the opposite, once the knee is stabilized, the risk of a tear of the meniscus is minimized.

10. Distant problems

The changes in gait and posture can affect all three other legs, as well as the spine. Weight shifting may cause or exacerbate an orthopedic problem in another leg.

A doggie physical therapist told me once: “An ACL rupture is the beginning of a cascade of events in other body parts – joints, muscles – that we can’t forget.”

To a degree, some of the above changes can be used to “date” an ACL tear. From experience:

. A patient with a recent ACL tear classically is lame and painful.

A patient with an old (chronic) ACL tear typically presents with limping, pain, arthritis, decreased range of motion, muscle atrophy and weight gain. In surgery, we certainly see much more bone spurs in a dog with a chronic tear than with a recent tear.

From a surgeon’s standpoint, an ACL tear is a very fixable problem.

Sure, it is possible to live with a torn ACL. Certainly, it might be the only option if you absolutely cannot afford surgery.

ACL surgery has changed dramatically over the past few years. I now expect a return of at least 95 % of normal function in at least 95 % of my patients of any size after ACL surgery, of any type.

So it’s hard for me to believe that affected dogs, especially large ones, have (and will have) a good quality of life with an untreated ACL tear.

From Florida to Pennsylvania: Mae Mae the Lab gets “a new lease on life” after tie back surgery for laryngeal paralysis

This may be one of my craziest success stories ever, and definitely my furthest traveling patient ever.

Mae Mae, a 10 year old Lab who had laryngeal paralysis (which we call “lar par”), was traveling from Florida to NY State with her owner.

As they arrived in Pennsylvania (where I live), Mae Mae had a severe bout of suffocation. Her owner contacted me after finding me on my website. His dog was in serious trouble.

In his own words: “We were on our way from Key West (FL) to The Adirondacks (NY). As we were driving through Harrisburg, PA, around 11 pm, Mae suddenly couldn’t breathe. Her lar par had, in an instant, gone from manageable to life threatening. Fortunately, we were close to a vet ER. They saved her life. They said she was very healthy and a good candidate for lar par surgery.

I sent you an email and was blown away to receive an almost immediate response and then a call. I knew then that Mae Mae was meant to be there in Pennsylvania at that moment and she was meant to live.

We scheduled Mae Mae for emergency surgery at www.BrodheadsvilleVet.com. Surgery went well. She then recovered well with her owner.

Great night sleep, for both of us. She’s doing well.”

But then it occurred. The dreaded complication happened: aspiration pneumonia. This is a type of pneumonia due to aspiration, or inhalation, of food, water, saliva or vomit into the lungs. Mae Mae was coughing and was extremely weak. She had no appetite.

She went to the local ER (www.BartonHeights.com).

She spent a week in the ER. She had been through so much. She had literally given up. Because of COVID, I wasn’t allowed to see her. She was finally allowed in a private room where I spent half the day with her, every day. I would lay on the floor with her for 5 hours a day and try to get her to eat a little. Every day, she made a little more progress.”

It’s true. It looked as if Mae Mae had given up. She wasn’t fighting. So we fought for her. The doctor team and the nursing team did everything by the book to treat the pneumonia: antibiotics, nebulization, antibiotics, coupage, and lots of TLC.

Her biggest cheerleader was her owner. Despite the financial commitment and the emotional rollercoaster, he stood by her side, literally, as much as possible. In the end, Mae Mae recovered and finally continue her trip to the Adirondacks.

Her owner and I are convinced that she recovered thanks to the amazing dedication of one particular nurse, which we will call Shelly.

Mae Mae is a special soul. You (Dr Zeltzman) and Shelly provided the best medical care I have ever experienced for pet or human. I will never be able to thank you enough.

Thank you for giving Mae Mae a new lease on life. Literally it has been like watching her be reborn. She is 10 years old and I am grateful I will get the opportunity to watch this precious soul grow old.”

Then Mae Mae travelled back home in Florida.

After 1 month, she was doing well, but was still pretty weak.

After 2 months, she is happy and much stronger, as shown in this short video: https://youtu.be/67WiKl9tpr4

Bottom line: “lar par is not a death sentence.” It’s a treatable condition. It has definite, well-known, possible complications. Even if we end up with aspiration pneumonia, most dogs who are treated aggressively can overcome this aggressive and potentially deadly complication.

Thanks to her owner’s amazing dedication, Mae Mae can breathe easy in Key West, where she enjoys a life of rest, walks on the beach, good food and puppy love.
