It is extremely rare for all these tests to be normal in a dog that is a high anesthetic risk.
When we know of problems in advance we can make modifications in anesthesia that protect your pet's life.
Various anesthetics are administered in one of four ways.
They can be injected locally around nerves,injected into the muscle to work systemically, injected intravenously to work more rapidly or they can be inhaled as a gas.
Many times, I have forgone anesthesia in a pet when I was dissatisfied with the results of my physical exam.
Veterinarians that have worked in the Profession for as long as I have, usually develope the ability to sense the general health of the animal they are examining.
Injectable anesthetics now each have their specific reversal agents and the gas anesthetics we use are quickly reversed by ventilation as your pet breaths them out of it's system.
So the difference between your pet being sedated and your pet being anethetized it blurry.
Once the sedative or tranquilizer has taken effect I shave the patient’s arm and place an intravenous catheter in its recurrent radial vein.
This gives me easy access to the pet’s blood stream for fluids and other medications in the event of an emergency.
When examination leaves me with uncertainties I schedule a group of biochemical tests to gauge the health of the major organs of the body. Glucose analysis and total blood proteins detect diabetes or other debilitating diseases and an EKG may detect heart problems.
Include a hematocrit, a differential and total white blood cell count.
