What you need to know if your pet is having surgery…….
Frequently asked questions:
WHY SHOULD MY PET BE TESTED ON THE SAME DAY AS THE SURGERY?
- If your pet is having dental work or surgery, it is important to run same-day blood work prior to anaesthesia primarily to ensure your pet can properly process and eliminate the drugs given to induce and maintain anaesthesia. It is especially recommended in animals over the age of 7 years, as they are more likely to have problems.
- Pre-anaesthetic testing helps us understand whether your pet’s vital organs are functioning properly and alerts us to potential underlying diseases, which can help us create an individualized anaesthetic plan for your pet and avoid potential complications during surgery.
- Regardless of why your pet is being anaesthetised, pre-anaesthetic testing establishes a baseline for their individual health, which is helpful for future reference.
WHAT INFORMATION WILL THE RESULTS OF MY PET’S BLOOD WORK SHOW?
- The blood sample is collected from a vein in the foreleg or neck and is used to check your pet’s blood cells (haematology part ), liver and kidneys as well as for diabetes (biochemistry part).
- Haematology is the check on the blood cells. Anaemia is where the red blood cells are low and this could be a worry if the operation is likely to cause a lot of blood loss. If the red blood cell level is high this is most likely a sign of dehydration so your pet is likely to need to go on a drip. A high white blood cell count is usually a sign of infection so your pet may be put on antibiotics.
- As anaesthetic drugs are mainly removed from your pet’s body by the liver and kidneys it is important to know how they are functioning.
- The liver is checked by measuring two enzymes in the blood, which are normally at very low levels. Any damage to the liver cells causes a release of these enzymes into the blood and can indicate an underlying problem that will need investigating.
- Urea and creatinine are removed from the blood by the kidneys so if the kidneys are not working properly levels rise.
- It is important to also check a urine sample to see how concentrated it is when looking at kidney function.
- Glucose is measured to ensure your pet is not diabetic (a urine sample will be required to interpret the result) and to make sure they have enough energy for the duration of the operation.
WHAT CAN I DO TO PREPARE MY PET FOR SURGERY?
- Make sure your pet has not eaten anything (fasted) at least 12 hours before surgery. Fasted samples ensure more accurate testing and interpretation of results.
- Bring any medication your pet is taking and consider taking along a favorite toy. The comforts of home can be a great help to your pet during recovery
- Ask questions if you don’t understand what is being done or why. Surgery can be complicated, so it is important to know all you can about your pet’s health.
