6th Grade

Calving season is finally slowing down. Although the entire season has potential for unusual and unexpected things, sometimes the end brings the biggest surprises. Yesterday and the week before I had similar experiences. I was told by one of our office personell that there was a heifer coming that was calving. Now for those of you who are not particularly farm animal terminology savvy a heifer is a young female of the bovine or cattle species. In general that name applies to all females up until they have their first calf. Naturally I assumed that my soon to arrive patient was the typical two year old heifer having her first calf.
When the heifer arrived I soon realized that something was not as previously assumed as the heifer was much smaller than would be expected. This was particularly evident as I had just been out to Bangs (Brucellosis) vaccinate the heifers of this farmer and knew that he fed is cattle very well. In fact she looked no bigger than any of the those just coming yearling heifers I had vaccinated a few months previously. I am sure by now that many of you have guessed that she actually was one of those heifers and was now just over 14 months.
The first heifer's calf was delivered by a C-section.

The heifer from yesterday was a small black angus heifer that probably didn't even weigh 800 lbs (mature weight can be anywhere from 1100-1800 lbs). The owner had looked at her ear tag and found that she was just over 13 months old. Of course I did the math in my head and realized that this heifer had to have been bred when she was a 4 1/2 month old calf at her mother's side and here she was 9 months later with her own bouncing bundle of calf. I guess this is what would be the animal kingdom equivalent of a 6th grade pregnancy.

Wallow

If I could choose to be an animal it would not be a pig.

It had already been a very busy weekend on call with more than enough challenging and patience-trying cases to go around. I was driving home and was one block from my house when the phone rang yet again; a heifer with a uterine prolapse, could I please come right away. I called my wife and reassured her with these foolish words, "He doesn't live very far away, so it hopefully won't take very long."

As I may have mentioned previously we have had an awful weather winter. Record snowfall combined with record flooding. Then to make this weekend extra nice we got rain, followed by snow, followed by pouring rain, then more snow, then a little more rain. I think wet and cold pretty much miserable sums it up.

When I arrived at the farm the farmer greeted me with, "She was going crazy in the chute so I tranquilized her, and now she laid down". Normally that would not be a problem but this chute happened to be a small old chute that neither side would open on and she was twisted and cramped sideways with her legs tucked far up underneath her. Normally I would try and get both legs out behind the cow and the uterus goes in much more easily but that was not an option. Hoping that maybe this time would be the exception and everything would go in easily I went right to work.

I got the uterus cleaned off nicely and starting stuffing things inside without too much ado. It was like the heifer had a threshold for a specific amount of uterus that she was willing to have inside of her. Once I got to that point and tried to push any more she would give a big abdominal thrust and push everything back out on top of me. Not one to give up easily it quickly turned into a push-o-war. Me pushing in and her pushing out. Now the part that I failed to mention was that this chute we were working in was outside in the middle of the corral. In order to get a good angle on this laying down, butt twisted sideways and downwards uterus, I got to play pig in an 6 inch deep puddle of muddy water and you-know-what-else-turns-water-brown. Fortunately I was wearing my waterproof bibs, OB top, and overshoes. Unfortunately, that was not enough and I still ended up stinking and soaking. I don't understand the thrill that pigs get from that. The worst part was that she was winning and the uterus was not going in.

Next we tried letting her out (with a halter on tied to the side of the chute). Of course she was too sedate and wouldn't move so the farmer got his loader tractor to pull her out of the chute to put her in a more workable position. Perhaps she could sense our intentions as the loader pulled up toward her head and she suddenly had enough energy to stand and walk out. Now I was able to get the uterus back into the heifer without too much trouble...just a little dancing back and forth through deep mud, trying not too get my shoulder dislocated.

Today I did not love being a cold, wet, dirty, and my wife would add stinky, country vet.

C-section on the side

Many times I have pondered how things would be different had I decided on human medicine rather than veterinary medicine. Often when working with farmers or pet owners they comment on how much smarter veterinarians are than human physicians because we have to be able to diagnose the problem without the luxury of verbal communication from the patient. Add to this the frustration when the statement "hold still, this will only hurt for a minute" has absolutely zero affect on my patients. I guess the closest comparison could be with pediatric doctors working on babies. At best this is a weak comparison as I don't know many babies that would like to kick you into next week or toss you over the fence for doing something painful to them.

Some of these uncooperative patient thoughts came to mind on a recent calving call that I went on. I arrived a the farm just as yet another blizzard was starting. An unimportant side note but this one dropped somewhere between 15- 20 inches of snow and brought the grand total less than two inches shy of the all time snow record for the area. Loving winter here for sure. Back to the story. The cow was a smaller cow expecting her second calf. When I arrived she had a very large set of feet sticking out the back end and the farmer had already tried to pull it. Some of our farmers are not very experienced in offering assistance but this was not one of those. I knew even before getting to the farm that this was most likely going to be a C-section. The set up was a very common calving pen for our area; a head catch next to a wall with a swing gate that fastened with a chain to the wall to hold the animal relatively still for calf deliveries. I noted as we were pushing the cow against the wall that some pressure had to be put on the gate to get it close enough to hook the chain. The top half of the gate could then be swung open to allow easy access to the left para-lumbar fossa (the area in front of the hip bone and behind the ribs where we make our incision for a C-section). I proceeded with my c-section; all appeared to be going well as farmer Jake and his adult son were both there and ready to help.
No sooner had I completed my incision into the abdominal cavity then the cow decided she was tired of standing and laid down. In the clinic this is no problem at all as we just open one side of the chute, position the cow on her right side and continue the surgery there. Instead we were dealing with the setup on the farm and were just starting to find what problems we were going to have. With her now laying down body wedged against the gate it was impossible for the three of us to apply enough pressure to be able to unlatch the chain. Complicate this with the open hole in the left side of the cow with her trying to rub her rumen and other intestines against the far-from sterile swing gate. Fortunately we were able to bend the latch and get enough pressure to release the cow. Unfortunately this freed her to immediately push against the wall with her feet and roll onto her left side. Suddenly the swing gate was very sterile in comparison to the barn floor covered in straw, dirt, urine, feces and anything else nice that you might find on a barn floor. While I futilely attempted to keep my hands covering the 15 inch incision, farmer Jake and son tried to push the cow up off her left side. A quick phone call brought reinforcements from the house in the form of the other adult son and our cow was able to be tipped up to be sitting upright.
After scrubbing up again as best I could I was ready to get this calf out and reached in to try and pull the calf over to the opening in the body wall. She had other ideas and decided that now was as good a time as any to try and push the calf out with all her might. With each new push came part of the rumen, often accompanied by intestines protruding out of the incision, each time only inches from touching the dirty floor before I could get them back in. As this was definitely not working we readjusted again and laid her over on her right side hoping for better success.
Stupid cow, as I had by this time named her in my mind, was trying her best to be as uncooperative a patient as possible. I am not sure why she had such a death wish, but it sure seemed like she was doing everything in her power to get herself started on a really good abdominal infection. Even on her right side she continued to push with all her might and would repeatedly pop out her rumen and intestines despite my best attempts to keep everything inside. First point against me: the cow was repeatedly pushing her guts out. Second: the calf was very large and in the down horn; as absolutely far from the incision as it possibly could be. Third: the rumen was very full and putting a great deal of pressure down on the calf. What had originally appeared to be just another night at the office was turning into anything but. After several unsuccessful attempts to move the calf anywhere near the incision with constant pushing from the cow my thoughts of human physicians being able to ask their patients to hold still reverberated in my mind. Farmer Jake must have been having similar thoughts as he asked if we could sedate the cow. After expressing my concerns about likelihood of losing the calf he still felt that was our best option to complete the surgery and I had to agree.
An IV injection of xylazine in the underside of the tail worked almost immediately and I was ready to pull out a calf. Unfortunately (this seems to be a recurring theme in this story), though we had solved point one against me, points two and three were still insurmountable and I had to do something I have never done previously and hope to never have to do again. Because I could feel the feet deep inside the cow, but was completely unable to move them, I needed to get some extra help. I took my scalpel, held tightly between my thumb and forefinger to cover the sharp edges, and reached deep inside the cow. The whole time in my mind I was praying/hoping/wishing that she didn't override her sedation and decide to push just at the wrong time. Thankfully, I was able to blindly cut the uterus over the point of the hoof, without cutting my fingers or her intestines in the process. With access to the hooves I was now able to put a chain around them and have my two helpers pull the calf up and out. It made me feel better that the two of them together still had to sweat and struggle to get the 130 lb calf out.
Now the race was on to see if we could revive the very sedate calf before it died. A slow IV of tolazine to reverse the sedation, combined with an injection of the respiratory stimulant dopram did wonders for the comatose looking calf. Fortunately, he quickly came around and was trying to stand up even before I was done sewing up the cow. Before too long the sedation began to wear off for the cow and she began pushing and kicking but with two guys sitting on her neck and shoulders and one more holding her back legs tied to a post we finished the job. She appeared no worse for wear and I was off again; into the blizzard to help some other cow that wouldn't stand, or lay, still when I told it to.

Anger management

Springtime in a mixed animal practice generally means one thing: calving season. Saturday was a usual busy calving day with a wide variety of calls from farmers with sick calves, calving problems, and uterine prolapses. I was momentarily at a loss for words when Farmer Fred called and said,
"I have a heifer calving and I just got her into the barn and she went Ape-@#$%.!"
"What do you think I should I do?"
After getting clear in my mind what he had just said I replied,
"Leave her alone for half hour to an hour and see if she will calm down."
I recommended this mostly due to the fact that many cows can get themselves worked up into a frenzy with too much stimulation especially during a stressful time like calving. I also recommended this because I knew I was going up to the area to do a uterine prolapse and I wanted to buy a little time to complete that task. The farmer made it clear that he would be calling back in about an hour if her mood wasn't much improved and would be wanting my assistance. I decided to throw in the dart gun just in case. Sedating a cow that is calving is a really last resort thing because the calf will also be sedated and that combined with the stress of delivery is often too much and we lose the calf. In real bad cases where the cow is also very stressed and down for a long time, you could potentially lose the cow as well

To no-one's surprise my phone had a couple of voice mail messages as I left the farmer with the prolapse, one of which was another plea for help from farmer Fred.

When I arrived on the scene it didn't take long to evaluate the situation and surmise that we were in for a bit of an adventure. Farmer Fred quickly warned me that we would have to dart her because she would try to kill anyone that got close to her. The heifer was in a large pole barn with one other cow and calf. The only door that wasn't frozen shut from excessive snow and ice we had received this winter was in the middle of the east side. There was a head catch with one length of panel next to it in the northeast corner, about 20 yards from the door. The remainder of the barn was wide open space without any other corrals or posts. Our patient was standing in the northwest corner facing the door and charged full speed towards us as we attempted to enter. At a distance of about 30 yards my pistol was not particularly accurate and I needed to get a better shot that wasn't head on. After a couple more futile attempts to enter slowly I began trying to calculate whether I could run fast enough to reach the safety of the panel and head catch before the angry cow could get to me. Even though I ran sprints in high school track I would have to put my money on the cow to win this match race.
With that decision made I began to look around the barn for other options and noticed the rafters and 2x4 braces running horizontally the length of the wall. Spaced like a giant ladder up the wall I realized they were the key to success. I handed my loaded dart gun to farmer Fred and quickly climbed the 2x4s up the wall to the rafters. Fred handed me the gun and I began the climb down the length of the barn halfway hanging from the rafters with my toes walking along on the 2x4 on the wall. Awkward would be an apt description of my movement along the wall hanging/climbing all the while carrying a loaded dart-gun pistol. The cow watched the entire time taking several threatening steps forward. As a result when I reached my destination and jumped down behind the panel she was a short easy shot away. Several minutes later she was down for the count and we sprang to action, hoping that we would be able to get the calf out fast enough to save its life.
Of course, that is not the end of the story. Because my truck was in the shop for some repair work I was borrowing the truck of another doctor and as a result all of his equipment. I got the cow tied up and held down with a rope with a quick release mechanism on it which we soon found out was broken. The cow made one thrashing motion and the quick release did its thing and she was up and we were running faster than you could say "angry cow on the loose".

For my next trick I got another rope; this one a simple lariat. First I tried to toss a loop over the panel onto the head of our angry, yet very sedated, patient. Several attempts of this were unsuccessful and I finally climbed the corral panel. Standing with one foot on either side, almost like you were standing up pigeon-toed in the stirrups on an emaciated horse, I swung my loop like a real cowboy and caught her first try. Surprised at my good luck but needing to hurry we finally got her to go down and we were able to pull the calf without too much effort.

The newly delivered calf was alive but very sedated. I quickly grabbed my reversal and gave it slowly in the vein. I must say that having to give a drug slowly is irritating when you are trying to save a life. I love happy endings and this was one of those. When I left, mom and baby were both alive and well and I was off to my next adventure.

Sad Cat

I realized I hadn't posted any stories about cats. I will admit they are not my very, very favorite patients (the whole claws on every foot, sharp teeth, reflexes much faster than my own, and a willingness to use all three) but this story deserves to be told. A few months ago I met an energetic kitty named George. George came in with a complaint of occasional vomiting. He seemed like a happy and healthy kitty and the owner said he was "full of life" he would just vomit every once in a while. Now of course as a veterinarian we love to have something come in the only problem being occasional vomiting. With that history we can usually narrow it down quite quickly to only two or three hundred possible causes! Because the cat seemed to be doing so well otherwise, was a finicky eater, and bloodwork only showed an increased eosinophil count (type of white blood cells usually increase with parasites and allergies), the owners opted to try deworming and changing food rather than pursue further diagnostics at that time. With instructions to get back in touch with us if things didn't improve or got worse, I didn't give the cat another thought. That was of course until a couple of weeks ago when I was requested as a doctor to look at a cat that I had seen previously for vomiting.

When George walked in, or should I say was carried in, (cats don't generally walk into the clinic on their own), I almost didn't recognize him. This previously very playful cat was lethargic and for lack of a better word, emaciated. For those of you who are familiar with body condition scoring, he would be about a 1 out of 5. According to the owners they had tried several different foods which he generally didn't eat well and his vomiting had slowly increased over the past few months. Within the last couple of weeks they reported his condition deteriorating much more rapidly. As is the case with many pet owners, economics often plays a role in diagnostic and treatment plans. This owner was no different and had difficulty making the decision to take x-rays after other diagnostics had not yielded specific answers.

Fortunately radiographs were taken and revealed a very obvious answer to our several month problem. What appeared to be a perferctly round white spot was located in the abdomen near the pelvis. When the owners were brought in to view the films they both exclaimed "It's one of those glass beads". After more discussion it was determined that he must have eaten the decorative glass bead, the kind that you may see in a vase or on a glass plate, about 2 months prior to his first visit.

Next the discussion turned to options for treatment. It boiled down to two: surgery or euthanasia. Surgery was chosen after a long discussion about complications due to the severely debilitated state of the patient.

In surgery we were not surprised to find half a dozen places in the intestine with partial constriction. It would seem resonable that all of these locations were places where the bead had gotten stuck on its several month journey through the intestines and the damage to the wall of the intestine had resulted in the noticeable scarring and strictures. The marble was removed and surgery was completed without incident.

Unforntunately George did not recover well from surgery, was unable to mantain his own body temperature, showed signs of brain damage and was euthanized two days later.

Monkey?

I was out at a farm to pregnancy check and "Bangs" (Brucellosis) vaccinate some heifers. Things seemed to be moving along at an okay pace until we got one heifer that was just a little too impatient. As each heifer would come into the chute we would drop the tail gate so that the next heifer couldn't crowd in as well. This tail gate had a horizontal bar on the top and bottom and then vertical bars about 6 inches apart across the width of the gate. Well miss antsy just didn't have the desire to wait when the gate was dropped in front of her, reared up and stuck her legs over the top horizontal bar. Had this been all there probably would have been no problem as all she needed to do was pull her legs back down and she could stand quietly in the alley. Instead she jumped up stuck both of her back legs through the gate and hooked them over the bottom horizontal bar. Now we had a 700 lb heifer hanging on the back gate of the chute like a monkey. Of course, she was not complacent in her position and after a few seconds of the monkey-cling she began thrashing around. With no room to go forward and all four legs hung up on the gate there was only one option...backwards. Yes, she flipped herself completely onto her back on the ground, wedged between the sides of the alley. Then, like one pig waits for another at the feed trough, the next heifer in the row immediately proceeded to walk right on top of this upside-down heifer to try and push her way into the chute.

Fortunately for me we actually had several people there helping and after we got all of the other heifers out of the chute and alley we devised a plan to get our wedged turtle out as well. We fashioned a rope halter out of a lariat and while one man lifted and pushed on her head, the other three of us pulled on the rope and we were able to flip the heifer back over in the reverse direction that she had just gone. No worse for wear we finished the job and everyone was happy.

When people say cows aren't athletic I think of experiences like this and just smile.

Winter

One of the first questions that I asked before I came to North Dakota to visit was, "How bad are the winters really?" Now keep in mind that I grew up in Montana so a little cold doesn't frighten me. Unfortunately, the person who answered that question for me was also the one who was a transplant to North Dakota and had not been here that many years. His response was "Oh, they really aren't that bad; they are just like Montana winters".

When I came to interview it was the end of November and there was a storm the week I was here. It snowed a few inches, had some wind, and the temperature even dropped a few degrees below zero. Then after we had made the decision to take the job, we came out to house hunt in February. If you guessed that there was another snow storm you are very smart. It snowed several inches and got cold (down around O F again). We weren't too fussed about it after everyone reassured us that we had been here for about the only two storms for the winter, this was about as bad as it gets, and that North Dakota winters really hadn't been that bad for several years.

Fast forward to now. I realize that much of the country is experiencing really potent winter weather, but today's experience warranted some documentation. We are the veterinarians for two sale barns and our duties rotate among the doctors each month so we each get one day a month at each sale barn and they do not cancel due to weather. Today was my day. This morning was bitter cold....so much so that when we got gas on our way out of town several of the pumps were not working because they were frozen. As we were driving I was looking across the drifted white landscape and wondered out loud what our snow total was at. We are now at over 6 feet of snow for the year. With over 30 inches in December alone and only one day that came close to 32 degrees since the middle of November, all of the snow is still around. Up till now we have had cold days. However, a new record for ridiculous was set on our drive today. Just before arriving at the sale barn to start our day the thermometer read......
........-40 F !
What a great day to be a large animal vet that works outside!
