Fall in the Northeast is probably my favorite time of year.
The red, orange, yellow and gold colors are abundant and make the scenery even
more beautiful than it already is. Dunkin Donuts has pumpkin donuts, pumpkin
coffee and pumpkin muffins and the fresh apple cider can’t be beat!!! Along
with the fresh cider is an abundance of fresh apples to make pies, apple crisp,
applesauce… and the list of my favorites goes on.
We’ve all heard the saying “an apple a day keeps the doctor
away.” As much as I love apples, cows
tend to love apples too. Unfortunately,
when cows try to eat apples, it’s more of a request for a visit from the doctor than it is to keep her away…..
I’ve had two calls in the last week from clients that thought
their cow was not eating or drinking, was coughing and acting “off.” The most recent call was much more emergent
in the fact that the farmer brought the cow in from pasture and she was
extremely bloated. The owner thought he felt something hard in the cow’s
throat, but wasn’t really sure if it was real. When I arrived I found #100 lying down, very uncomfortable,
with an extremely distended abdomen, cold ears and obviously in distress.

Severe Rumen Bloat |
As I’ve discussed before, when a cow bloats, it causes
severe pressure on their diaphragm and lungs and prevents them from breathing
easily and efficiently.
As you can see
from the picture, she was severely distended, so my first order of business was
to relieve the bloat and allow her to actually be able to catch a breath.
In order to relieve her bloat, I placed a red
trocar in the rumen as I have also discussed in a previous
post. Once the bloat was relieved, and she was able
to take a breath, I was able to examine the rest of her.
As I was looking at #100 I was asking the
farmer if he had any apple trees in the pasture.
His response was “yeah a pile of them.”

The obstruction visible in the shaved area |
Feeling the cow’s
neck, I was able to palpate a large baseball size lump, about half way
down her neck.
I was pretty positive she tried to eat an
apple and she ended up swallowing it whole and was now choking on it.
Because cows do not have upper incisors, they
can’t just bite into part of an apple. Usually they end up putting the entire
apple in their mouth and then try to bite it with their molars. If the apple is
hard it may not break and can shoot directly down their throat, or the cow will
just try to swallow the apple whole.
It’s
great if they can actually get the apple to their stomach without any trouble,
but if the apple is bigger than the esophagus, it can cause some major issues.
The first call I had with this issue, was a small beef cow,
which must have eaten a smaller apple. By the time I arrived, she had passed
the apple on her own and had started to nibble on hay and drink some
water.
She was started on some
anti-inflammatory medicine to help with the soreness and any trauma the apple
caused on its way down.
She was in a
much better way than #100.
The approach that I take when I am faced with an animal
choking is to first sedate the animal.
When an animal is choking, much like a human, they begin to panic and
all their muscles, including the esophagus, will tense. With sedation, we hope
that the animal will relax enough that we may be able to massage the
obstruction down the esophagus, or when we pass a tube down the esophagus, we
will be able to move the obstruction with the tube.
Once #100 was sedated, I took a firm tube and tried to move
the apple down the esophagus. It wouldn’t budge.
Because the esophagus is a smooth muscle, and
kind of an important muscle to have, it’s crucial not to be too forceful when
trying to remove an obstruction, causing more damage. When the apple wouldn’t
move with the gentle pressure of a tube, I went to my next plan- pumping water
down her throat to try and “flush” the apple down, rather than adding more force.
As I was pumping the water in, she was
spitting it right back up as fast as I was pumping it. After trying to pump 3-4 gallons of water down her,
I decided it was a futile effort.
Now I’m
not sure what I’m going to do… The poor cow was still coughing and trying to burp to get
the apple up, and what I was doing was not working.

Another view of the obstruction |
I thought about pumping mineral oil down her throat, to "slide" the apple down, but
because she was spitting up the water so
forcefully, I was afraid she would do the same with the oil and possibly
aspirate on the oil. It’s pretty much a
death sentence if she ended up aspirating oil. And, even if we were able to move the apple
down the esophagus further, because of the size of it, there was still a chance
that the apple would lodge where the esophagus meets the stomach or somewhere
in the esophagus where it passes through the chest cavity. I didn’t see many good outcomes with this
idea.
So, in my gut, I figured we were headed for surgery, but I
wanted to bounce ideas off of another vet first, so I called another vet in the practice. She
was wondering if there was any way I would be able to put something down her
throat to mash the apple up into smaller pieces so it would pass. My concern was the trauma to the esophagus in
trying to pass something that would do the "mashing," and then what happens
if we lose that down the throat too?????? She also suggested I try to reach down and
grab it as someone pushes it back up to me.
Well I do have long arms, but they aren’t that long… And I kind of need
them to do my job, so I wasn’t real keen on putting an arm down a cows mouth
and have her, as a natural reaction, bite
down on it…..
So, now I’m back to surgery as my option. Any other choke I have dealt with, cow or
horse, I have been able to relieve the obstruction with all the aforementioned
ideas, which means I have never actually done a surgery on a choke case. Well one of the great things about veterinary
medicine is that you learn to improvise, and you do so under duress. I know how to do surgery, I mostly remember
my anatomy- well at least the important things in the neck region; like the
jugular vein, carotid artery, and some
pretty major nerves, so I’ve got it covered…..
Ha!
I tied the cows head up in the air so that I was working
directly under her. After I clipped and washed the area, I blocked it with
lidocaine and started my exploration.
Being careful not to cut through any major things, I took a great deal
of time NOT using a scalpel, but rather using my fingers and scissors to
dissect through the tissue. Once I
reached the esophagus, I was able to cut over the top of the apple and see that
it indeed was an apple; a yellow-green one at that!
Now for my vet friends reading this, I know you aren’t
supposed to cut directly over the obstruction, but based on location, I didn’t
want to sway too far in either direction. So I went with it.
After a fair amount of work, using scissors and my fingers,
I was able to get the apple removed from the esophagus. I could tell that #100
was feeling much better the minute I removed the apple because as she coughed,
I had a face full of saliva and rumen juice spew out at me through my opened
esophagus.
I sutured her closed and could
tell that it was truly closed when I no longer had saliva coughed in my
face.
I then sutured the muscle layers
closed and then partially closed her skin, leaving a space for any drainage
that may occur.
I was concerned about
infection because it wasn’t a truly sterile procedure and I am not 100% sure I
removed all apple chunks or rumen fluid that may have come through the opened
esophagus when she coughed.

The culprit in pieces. |
She was placed on an anti-inflammatory medicine and
antibiotics. When I called to check on her the next day, the farmer said she
had started to pick at some food but wasn’t eating with vim and vigor quite
yet. I can only imagine how sore her
throat must be with having the apple stuck in there for who knows how long, and
then me trying to get the apple to move with tubes, and finally the
surgery.
I still worry about aspiration pneumonia, infection
in the incision, as well as the esophagus forming a stricture at the point of
my incision and suturing. I am very
fortunate in the fact that cows have an amazing ability to heal and surprise me
every day with that ability. This was
certainly a new one for me. I never did
mention that #100 was due to have a baby in less than a month. After all this, I really hope she will be able
to have her baby and go on living a happy life AWAY from the
apple trees!!!!
