Pre-Operation Information

No one likes the thought of their pet undergoing surgery but there are certain problems and routine procedures which require surgical intervention. Do not be overly concerned. There have been many recent advances in veterinary medicine and surgery. Diagnostics, anaesthesia, monitoring and surgical techniques have been developed to help ensure your pet's safe recovery:


Pre-Anaesthetic testing

Pre-operative testing is often recommended to help us uncover any problems not readily apparent. These tests may include blood tests (blood cell counts and blood chemistry), and urinalysis. Any abnormalities detected may need to be corrected prior to surgery or may merely indicate a change in the choice of anaesthetic or pre-surgical treatment. In this way we can minimise surgical and anaesthetic risk. We offer Pre anaesthetic blood testing for all patients. 


Standards of quality

We use many of the same anaesthetic agents that are used in human surgery. Surgery is performed with the highest standards of sterility and your pet's heart, lungs and other vital functions are closely monitored by advanced machinery as well as qualified nurses. We offer all patients the option of inter-operative fluid therapy. This aids in blood pressure maintenance, kidney maintenance as well as a speedy recovery. In some cases, the Veterinarian will insist on intravenous fluid therapy.

These represent our normal protocols; we seek to provide high standards of quality veterinary care and will not lower them for any reason.


Pre-Anaesthetic instructions


  • Please give no food after 8pm the evening before surgery and take water away one-hour before admission. No treats and no cheating! An empty stomach is critical for safe anaesthesia. DO NOT however restrict food or fluids from rabbits, ferrets, rodents, or birds.
  • If your pet is taking medication that does not require food, give the normal dosage at the usual time unless otherwise directed. If your pet is diabetic, please ask the veterinary surgeon for special instructions. If your pet requires dosage throughout the day, please bring the medication with you.
  • Surgical patients are admitted to the hospital between 8.00 am and 9.00 am on the day of surgery.
  • Allow your pet exercise and time to empty bowel and bladder before being admitted unless otherwise instructed.
  • If you have any questions and/or concerns regarding the procedure please do not hesitate to call and ask any of our friendly staff.


Types of anaesthetics used

Your Veterinary surgeon will determine which anaesthetic is best for your pet and for the procedure being performed. Some short procedures are conducted under short acting anaesthetics injected into the muscle or vein. Most procedures however, are carried out under general anaesthesia. This involves an initial calmative and pain relief injection followed by intravenous Alfaxan and gaseous Isoflurane. These are currently the safest anaesthetic agents available for animals. This special combination of drugs results in minimal stress on your pet's heart, kidneys and liver while maintaining ideal anaesthetic levels. Consequently your pet will wake up more quickly and smoothly after his/her anaesthetic.


Other considerations

When your pet is undergoing anaesthesia for one procedure it is worth considering whether the opportunity should be taken to carry out any other procedure. If there is any degree of dental disease and if circumstances permit, the veterinary surgeon might advise that the appropriate dental treatment should be attended to at the same time. If you pet has an umbilical hernia or loose dew claws and is being neutered, it may be recommended that these be surgically repaired at this time.

You should be provided with a written estimate of the expected fees and other charges that will be incurred. You may request your bill-to-date at any point during your pet's stay.



Be prepared to spend a few minutes with the Veterinary Nurse on duty the morning of admission. A Surgery Consent Form will need to be completed and pre-anaesthetic laboratory work will be discussed. This will also be an opportunity for any last minute instructions to be communicated.

If you would like to speed up the admission process, please feel free to download the Surgical Consent Form, read and answer the questions, and bring the forms with you.

We really do want you to understand what we are doing and why. If you have any questions about our procedures or your pet's condition, please don't hesitate to ask.
