At Perth Cat Hospital we take your cat’s safety very seriously. There are many things that we do to ensure that your special kitty’s anaesthetic is performed in the safest, most gentle and comfortable manner to ensure that their recovery is smooth and pain-free.

Once your cat has been admitted into the hospital, one of our vets will perform a thorough physical examination. We recommend that you remain available by phone in case the vet needs to discuss their findings with you. However, cats are masters at hiding signs of disease and a physical examination does not always detect underlying illnesses.

We recommend performing a pre-anaesthetic blood test on all cats prior to anaesthesia. Our on-site laboratory allows us to run these blood tests on the morning of your cat’s procedure which gives us real time results on their health status. These blood tests are very similar to what your own doctor would run if you were to undergo anaesthesia yourself.

Benefit of pre-anaesthetic blood testing:

1. To assure proper kidney and liver function; as they are primarily responsible for anaesthetic metabolism in the body
2. To assure adequate oxygen carrying capacity of the red blood cells
3. To ensure adequate platelet levels for blood clotting
4. To identify “early warning” signs of major blood and organ dysfunction
5. To establish base line parameters for your cat.

It is important to understand that a pre-anaesthetic blood test does not guarantee the absence of anaesthetic complications.  It will however reduce the risk of complications as well as identify medical conditions at an earlier stage.

All cat’s undergoing an anaesthetic in our hospital will have an intravenous catheter placed prior to induction of anaesthesia. Because cats are small animals, they have an increased susceptibility to develop a drop in blood pressure (hypotension) in association with administration of an anaesthetic. This can be quite severe in some cats especially those who are very thin, old or unwell. We also see an increased risk of hypotension during longer procedures.

Cats are also prone to hypothermia (drop in body temperature) when they are under anesthesia. Our hospital is equipped with  a number of devices to help minimise this potential complication for our patients. We have a Bair hugger machine which is one of the most effective ways to raise core body temperature. It does this by providing warm circulating in a blanket that is wrapped around the cat. In addition to this we also have a heated water blanket to use during surgeries where we want to restrict moving air in the theatre. We have a fluid warmer which is used to warm intravenous fluids such as saline prior to being infused into the patient, and finally our stainless steel surgical table is heated with a precise temperature control.

Many patients undergoing a general anaesthetic can benefit from administration of intra-operative intravenous fluids for the duration of their procedure.

Reasons for intravenous fluid therapy

1. Supports the liver and the kidneys by preventing a fall in regular blood pressure, this can be more common in an older patient
2. Maintains blood pressure throughout the anaesthetic. Up to 80% of all patients undergoing a general anaesthetic will experience a significant drop in blood pressure that could be detrimental to organ function.

All our anaesthetics receive a high level of monitoring with a dedicated nurse patient side as our anaesthetist for each procedure and they will care your cat from the very beginning of their procedure right through until they are completely recovered. We use high end monitoring equipment which measures their heart rate, ECG, respiratory rate, temperature, oxygen saturation, blood pressure and expired CO2 gases.

In following with one of our core values of excellence; we were one of the first hospitals in Australia to invest in the innovative v-gel airway devices specifically designed for use in cats. These devices are very similar to those used in human medicine. We are now using these devices in place of the older styled endotracheal (ET) tubes in many of our patients. The benefits of these v-gel are many including:

• They are made from a very soft gel-like material meaning  they are much more comfortable for the patient and easy to place
• They do not have to enter the trachea (windpipe) therefore they do not cause any damage or inflammation like traditional ET tubes tend to do
• They do not cause laryngeal spasm, coughing, gagging as seen in many cats with ET tube use
• They provide a greatly improved rate of flow of oxygen due to the wide diameter of the tube, what we call “less dead space”
• We have noted much better parameters on our anaesthetic monitoring equipment in patients with v-gels; such as better breath depth, oxygen saturation and more reliable anaesthetic delivery
• There is a notable improvement in recovery with most cats waking up more relaxed, less disorientated and comfortable.
