As we saw in the previous part of this series, Medical colics are those which can be managed medically, usually on the yard. However, about 1 in 10 cases of colic require emergency referral to an equine hospital for surgery.

This is what most horse owners are terrified of. The general indicators that a horse has a surgical colic are:

1) Heart rate over 60 that isn’t relieved by injectable painkillers.

2) Dilated loops of small intestine on rectal exam

3) Positive stomach reflux from the stomach tube

4) A definite rectal diagnosis of a surgical problem.

5) “Toxic rings” – dark red or purple gums, that indicate that the horse is going into toxic shock.

Of course, it varies between horses, and the vet has to make a judgment call based on all the evidence available.

We also have to talk to the (by now usually frantic) owners about costs. Colic surgery usually costs between £4000 and £5000, but can easily be a lot more. Even if the horse is insured, it is important to check how much the insurance company will cover – there are a couple of companies out there who will only cover part of the costs of emergency surgery. If in doubt, always call your insurer’s helpline.

However, colic surgery is one of the most genuine emergency operations there is – and it can be truly life-saving….

At one time or another we all have to face our beloved pets having an anaesthetic which can be a scary process if it’s not properly explained. Fortunately most veterinary practices have a fantastic team of nurses that can help you understand the procedure. (NB. I have used “he” in the article for continuity but this goes for all dogs a

and cats regardless of gender).

To give you a head start, here are some top tips:

1. The number one golden rule for preparing for an anaesthetic is no food after midnight (this does not apply to rabbits or guinea pigs). Also, some practices may give you an earlier time say nine or ten o’clock but the principle is still the same, basically no midnight feasts and no breakfast. The reason for this is two fold. The main reason is to stop your pet vomiting and potentially inhaling it. This can also prevent nausea on recovery. Another reason is to try and prevent any ‘accidents’ on the operating table which increases the risk of contaminating the surgical environment although to safe guard against this, some practices routinely give enemas and express bladders before surgery. So, while it breaks your heart to tuck in to steak and chips with Fido giving you the big brown eyes treatment console yourself with the knowledge that you are actually acting in his best interests to help minimise the risk of anaesthetic.

2. Give your pet the opportunity to relieve himself before coming into the surgery. Obviously this is easier with dogs but while we advise taking dogs for a walk before coming in we don’t mean a five mile hike on the beach with a swim in the sea, we mean a nice gentle walk around the block to encourage toileting. If you bring your dog in covered in dirt and sea water, you’re increasing the anaesthetic risk as we have to keep him asleep longer while we prep him. (See my previous article about how we prepare your pet for a surgical procedure).

3. Tell the nurse when she is admitting him whether you have noticed any unusual behaviour. Vomiting, diarrhoea, coughing or sneezing can all be indicators of problems and may need to be investigated prior to anaesthesia. Also tell the nurse if your pet is on any medication, when he last had it and bring it with you if you can. This way, if your pet needs to stay in after his operation, they will have everything he needs without adding extra to your bill…………

Once you relinquish your pet to the green fairies, you may be wondering what actually happens “out the back”.

Well, wonder no more. Firstly we make sure that we have an accurate weight for your pet as this is what we use to calculate the dose of the drugs that we give your pet. Once we have this we settle them in a kennel with nice squishy blankets while we go and get everything prepared.

If you have opted for, or we have recommended, a blood sample before anaesthesia then your pet is taken to a quiet part of the practice where we can safely take the sample. To take the sample, a patch of hair is shaved over the jugular vein which runs down the side of the neck, to one side of the windpipe and a needle is inserted to collect the blood. Most animals tolerate this quite well with the gentle yet firm restraint that we green fairies have down to a fine art. Some animals on the other hand object quite vociferously and may have to have the blood sample taken once they are anaesthetised. Not ideal but better if they are getting too stressed.

Once the results have come back and been received by the veterinary surgeon, they can decide what to pre-med with and whether the use of intravenous fluids is necessary. Intravenous fluids are usually considered if there is any elevation of the liver and kidney enzymes which show that these organs need a little help during anaesthesia as that is where most of the drugs used are metabolised. Some veterinary surgeons also advocate the use of fluid therapy during routine bitch spays as a spay is a fairly major and invasive procedure and fluids help maintain blood pressure and support the body during this procedure.

There are a few ways that we can induce anaesthesia in your pet. One way is to use the anaesthetic gas and get them to breathe the gas in via a mask or an anaesthetic chamber. This way is usually used with smaller creatures such as rabbits, guinea pigs and rats and they fit into the anaesthetic chamber and can have oxygen administered in this way before the gas is turned on.

One evening whilst playing outside, a little 6 month old kitten (let’s call her Tilly) climbed up a tree. A rather inexperienced hunter, when she saw a little birdie on the end of the branch she reached out to get it and, crash! The branch was too thin to support her weight and she fell to the ground. Now what they say is often true, cats do tend to land on their feet, but not always and poor Tilly landed on her side. She got up though and ran into the house, so her owner assumed she was OK. A few hours later her owner noticed that she was quieter than normal and not interested in her dinner. She was also breathing faster than normal but otherwise seemed OK, purring and affectionate, so her owner went to bed and planned to take her to the vet if she was still not right in the morning.

As you could probably guess, at 8:00 the next morning I got a phone call from Tilly’s owner, as she had not gotten any better overnight – she was still very quiet and breathing even faster than before. We told her to come straight down and we would take a look right away. A few minutes later Tilly arrived, looking quite sorry for herself, but still happy enough to give me a little purr. I did a full physical exam and found her to be in good health except for her breathing, which sounded quieter than normal through the stethoscope. Her respiratory or breathing rate was very high and she seemed to be struggling to get enough air in. She also seemed depressed, certainly not what I would expect of such a lively young kitten. Once we were certain that everything else seemed to be OK, we gave her some pain medicine and then a little bit of sedation so she would sit still while we took some x-rays of her chest. What we found was no surprise given her history, but still always comes as a bit of a shock when we see it – Tilly had a diaphragmatic hernia.

What is a diaphragmatic hernia?

The diaphragm is a large, thin muscle that separates the chest cavity (with the heart and lungs) from the abdomen (with the stomach, liver and intestines among other things). It is normally an air-tight barrier which allows the chest cavity to achieve negative pressure, in other words there is pressure on the lungs to expand out rather than collapse in. When the diaphragm moves down with each breath, the lungs move with it causing them to expand even further when you breathe in. And when it moves back up again, it helps the lungs to contract so the air is forced out when you exhale. Without a diaphragm or with a damaged one you can still breathe, just not very well, and this is what poor Tilly was experiencing. A hernia is the protrusion of an organ through a hole in the body cavity which normally contains it. In the case of a diaphragmatic hernia, a hole develops in the diaphragm which allows the organs of the abdomen to enter the chest cavity……………………………….

For the past month our local radio station has been bombarding us with adverts asking us to give blood due to increased need over the holidays. My husband and I ignored them at first but then eventually gave in. On the way home after giving blood, we started talking about cats donating blood and I realised it had been ages since I’d seen a feline blood transfusion. They are relatively uncommon, especially in general practice, but it’s an interesting subject so I thought I might look into it a bit further. Hopefully your cat will never need a blood transfusion, but if they do (or if you’re just curious about the whole process!), here’s a little bit about what goes on behind the scenes.

Why would a cat need a blood transfusion?

The main reason why cats get blood transfusions is because they are severely anaemic, which means they don’t have enough red blood cells in their blood. Red blood cells are responsible for carrying the body’s oxygen, so not having enough of them leads to serious problems. Anaemia can occur for three main reasons – not enough red blood cells are produced (problems with the bone marrow or chronic diseases such as cancer), too many are lost (major bleeding after an injury or surgery), or too many are destroyed (autoimmune disease or poisoning). Mild anaemia is not a problem and the cat’s body… read more

My last article talked about a few of the dental problems most commonly seen in cats, and how easily they can be missed by both owners and vets. Remember, a cat with dental disease will probably act just like a healthy cat, but that doesn’t mean they’re not in pain! I’ll continue now by mentioning some of the preventative measures and treatments that can help keep your cat’s mouth healthy and pain-free.

What can I do to help prevent dental disease in cats?

Of the diseases mentioned previously, periodontal disease (gum disease) is by far the most common but fortunately the easiest to help prevent. Although genetics plays some role in whether or not a particular cat is going to have bad teeth, there are several things you can do to help keep the pain and inflammation to a minimum…

Also known as Bloat, Twisted Stomach, Gastric Dilatation-Volvulus or GDV, this condition is one of the most serious emergencies in small animal practice, and it can make all the difference to the outcome if it is recognised immediately.

There are two parts to this condition, the bloat and the torsion. Bloat is when the dog’s stomach fills up with gas, fluid, froth or a mixture of all of these, to a far greater size than normal. Torsion (volvulus) is when the whole stomach twists inside the abdomen so that it is closed off at both its entrance and its exit, just like a sausage which is twisted closed at both ends.

They may both occur together, or one may lead to the other. If bloat occurs first, the enlarged stomach is at greater risk of torsion. If torsion occurs first, bloating will definitely result….

Deciding whether to spay

Spaying or neutering a female dog is not a small operation, so owners should think carefully about all the pros and cons before deciding.

The main advantages of spaying are preventing pregnancy, preventing infection of the uterus (pyometra), preventing ovarian or uterine cancer and reducing the likelihood of mammary (breast) cancer, all of which can be life-threatening. It also prevents the inconvenience of having a bitch in season with unwanted attention from male dogs.

The main disadvantages are major surgery with associated risks, an anaesthetic with associated risks and the increased likelihood of urinary incontinence in later life. Fortunately, the risks involved in anaesthesia and surgery are very small indeed compared with the risks of the other conditions which are prevented by spaying. Urinary incontinence in later life is a nuisance but not very common, and can usually be controlled by drugs.

There is no medical reason to let a bitch have one litter before spay, in fact some of the benefits like protection against mammary tumours, are lost if the operation is delayed. Unless an owner is committed to having a litter, with all the work and expense that can be involved, and the bitch is also suitable in temperament and free of any hereditary problems, then breeding should not be considered…………..

I knew it was going to be a rough day when I walked in and saw that three of my ten morning appointments were vomiting cats.  Second only to the chronically itchy dog, vomiting cats can be one of the most frustrating things we have to deal with as vets because there are so many possible reasons why it can happen.  Anything from what the cat had for dinner last night to metabolic diseases that may have been brewing for years could be the cause, and distinguishing between them can take a lot of time, money and effort.  And that’s just for the vet – as the owner of a cat that vomits frequently myself, I understand how unpleasant it is to walk downstairs in the middle of the night and step in a pile of cat sick.  Be it on the new white carpeting or the beat up old sofa, it’s not pretty.  It may be a harmless hairball, but it can also be a sign of serious illness in your cat so it’s definitely worth getting it checked out by your vet.  If you are unlucky enough to have a vomiting cat, here are some things you may want to consider……..

This is one of the most commonly diagnosed endocrine (hormonal) diseases in cats.

Many older cats suffer from a variety of symptoms which might just be put down to ageing, or might previously have been attributed to kidney disease, but many of these will actually be in the early stages of hyperthyroidism. Over the last 20-30 years a great deal of research has been done on this disease, and treatment has improved as a result….
