On admission of your pet for surgery we will ask you to fill in a consent form stating that you have given us permission to administer an anaesthetic to your pet and that you understand the risks associated with it. We also ask you to accept or decline pre-anaesthetic bloods and IV fluid therapy. Please read the text below for more information on these two options.
Pre-anaesthetic blood analyses:
We offer and recommend pre-anaesthetic bloods prior to placing your pet under an anaesthetic. Pre-anaesthetic bloods evaluate the functioning of those vital organs that are essential in processing and excreting anaesthetic drugs.
Anaesthetic drugs are processed and excreted by major organs such as the liver, kidneys and lungs. As an animal ages, its risk of developing diseases such as kidney failure, liver failure and heart disease increases. These diseases give it a greater anaesthetic risk, meaning it is less likely to cope with the anaesthetic. It is therefore important that we are able to identify these conditions prior to placing your pet under an anaesthetic.
Some younger animals may also be at risk of developing organ disease, because of congenital organ defects. These can also be identified prior to surgery and precautions taken.
If you chose to run pre-anaesthetic bloods, a small blood sample will be taken from your pet and run on our in-house haematology and biochemistry analysis machine. This machine evaluates both the red and white blood cells as well as a number of enzymes and analytes which are associated with organs, such as the liver and kidney.
This test can be done on the day of the operation/anaesthetic, which means that there will be no delay in undertaking the procedure, unless the results indicate that the animal is not fit to cope with the anaesthetic.
As well as running pre-anaesthetic bloods we offer precautionary IV fluids to ensure that your pet copes as well as possible with its anaesthetic. One of the effects of a general anesthetic is a reduction in blood pressure and reduction in the heart rate. IV fluids help combat this by increasing the circulating blood volume of your pet. This helps improve blood circulation, oxygen supply to the tissues and drug excretion.
