Dogs should receive an overall blood profile before undergoing anesthesia

My 14 year-old dog “Bandit” has a small wart-like mass on his eyelid. Although it is likely a benign tumour it seems to be irritating him and I would like to have it removed if possible. My concern is that he is too old for the anesthesia needed for surgery. Is it safe at his age?

The anesthetics currently available for veterinary use are very safe and pose little risk if used properly and appropriate pre-anesthetic tests are performed. Many of these modern drugs are the same as used in human hospitals. The standard protocol consists of what is called “balanced anesthesia”.

This uses a combination of pre-medication, induction and maintenance agents to provide a good level of unconsciousness for the required procedure while affording a smooth, pain free recovery. If “Bandit” needs anesthesia for surgery (which he likely does if his eye is irritated), we recommend a full blood profile to reduce the risks and check his overall health.

These tests are similar to those your doctor would use if you were undergoing anesthesia. Preanesthetic blood testing is particularly important in older or geriatric pets, as they may have compromised organ or immune function. Blood tests should include a biochemical analysis and hematology. Blood chemistry is used to evaluate the status of the major organs.

The function of the liver and kidney is especially important as they metabolize the medications used. Hematology checks the actual blood cells to assess for anemia, infection and clotting factors.

Depending on the results, the dose or type of anesthetic used may be adjusted or, if indicated, surgery delayed. In addition, these tests establish a pet’s normal baseline values for future reference. The latest technology enables us to run these tests accurately in-house so results are available quickly.

Close monitoring of the patient during anesthesia also reduces potential risks. Numerous devices are available to assess respiratory and cardiac function during surgery. The veterinary technician is also well trained in anesthetic techniques and is an important part of the team that protects the patient’s well being.

So, although there is always a degree of risk with any anesthesia and surgery, it can be minimized and anesthesia safely performed on most animals, even “old timers” like “Bandit”.
