Surgical Services

SurgeryWe understand that surgery and procedures that involve sedation and general anesthesia are not easy experiences for you or your pet. At Eldorado Animal Clinic we strive to ensure your pet’s surgical procedure is as stress and risk-free as possible. Our surgeons are highly trained and and have over 60 years of cumulative experience doing an array of surgical procedures. Our anesthetists are also highly trained and experienced veterinary technicians licensed with the state of New Mexico.

Dr. T. Murt Byrne and Dr. Rebecca Tomasic perform the bulk of our surgeries. Surgeries performed at our clinic include such procedures as neoplastic tumor removals, abdominal exploratory surgeries for foreign body and tumor removals, emergency bloat surgeries, urolith (urinary stone) removals, c-sections, spays and neuters, feeding tube placements, some fracture repairs, and major tooth extractions.

Our doctors also work closely with veterinary specialists in the Santa Fe and Albuquerque areas, and are always happy to help with referrals.


Anesthesia and cardiovascular monitoring are essential aspects of every surgery we perform. We take anesthesia very seriously. We use the highest standard of anesthetic protocols and cardiovascular monitoring equipment to ensure that your pet receives the very best care while under general anesthesia . All of our surgical and dental patients start with a complete physical examination and in-house lab blood work. Blood chemistries and complete blood counts help identify any underlying medical conditions that may increase the risk of anesthesia and surgery. Each patient will again receive a subsequent full examination just prior to being anesthesitized, allowing us to tailor the anesthetic protocol based on your pet’s health, breed, size, and type of surgery.

During surgery and anesthesia, your pet is constantly monitored by trained and licensed veterinary technicians. Our state of the art equipment monitors such parameters as oxygen saturation levels, ECG, heart rate, respiratory rate, blood pressure and core body temperature.

Pain Management

Planned pain management is part of every surgical procedure prior to, during, and after each procedure. All hospitalized patients are monitored for pain. We have many options that can be tailored to keep all patients comfortable. At discharge, we may send additional pain management medication home with you and your pet after providing a thorough explanation of its proper use and dosage.

Preoperative Care

At Eldorado Animal Clinic our main concern is your pet’s post-operative recovery and comfort. Every patient that requires anesthesia receives the following care from our surgeons and licensed anesthetists:

1. Blood Work. Pre-op blood chemistries are performed to assure that kidney and liver function are normal as these organs are responsible for metabolizing anesthestic agents. Chemistries are also key to ensure that protein and blood sugar levels are adequate for post-op recovery and healing. CBCs (complete blood count) and/or hematocrit readings are also performed on all patients. Red blood cell counts and hemoglobin counts tell us whether or not there are an adequate number of red blood cells to carry oxygen. The white blood cell count is also important as it can indicate signs of infection or inflammation.

2. Fluid Therapy. Intravenous (IV) catheters are placed using sterile technique in every patient that is going to be anesthetized for most surgical procedures. This allows for fluid administration that supports blood pressures and tissue perfusion during surgery, and also provides our team with quick access to administer emergency medications. Typically a small area is shaved on your pet’s limb to ensure proper visibility of the catheter placement.

3. Pain Management. Pre-op pain medications are administered to reduce the depth of anesthesia required for many procedures and to make recovery more comfortable and to speed healing.

4. Airways. All patients have an endotracheal tube placed to aid in air exchange and the inhalation of gas anesthesia. Occasionally there is some tracheal irritation with the tube placement. If you notice excessive coughing at home please let us know.

5. Gas anesthesia is used for the rapid control of the patient’s anesthetic depth and for rapid post surgical recovery.

6. A licensed veterinary technician monitors every patient from the time it is anesthetized until they are fully recovered. During post surgical recovery, the patient’s body temperature, heart rate, and respiratory rate are monitored very closely. We use warm air-circulating blankets and plenty of blankets and towels to ensure that your pet maintains an adequate body temperature upon recovery.

7. Post operative pain management is provided and tailored to each patient’s needs. Pain medication will be sent home in most cases to help them feel better and recover more quickly.

8. Please do not feed your pet after 10:00pm the night before the scheduled surgery. Free access to water throughout the night and the morning of the scheduled surgery is fine.

At the time of your discharge appointment after surgery, your technician or doctor will go over post-operative instructions. Should any questions arise after you leave, our doctors and staff are available to answer any question you may have by simply calling us at 505-466-0650 or contacting us through our website.
