Veterinary Surgery for Advanced Animal Care Treatment

Today, much like in human medicine, veterinarians specialize in various fields of advanced treatment. The diversity of backgrounds, interests, and training of OVRS board-certified veterinary surgeons represent a unique professional team. They possess the knowledge, skills and technological capabilities to meet the needs of our patients. Additionally, access to specialized instrumentation and sophisticated equipment allows them to expertly perform and manage a wide array of surgical conditions, which include orthopedic, soft tissue, neurologic, oncologic (cancer), and thoracic problems. Our surgical staff keeps abreast of the latest techniques by regularly attending continuing education symposiums.

The highly-skilled staff of our surgical department features a team of experienced and dedicated licensed veterinary technicians, surgical assistants, and board-certified surgeons. Furthermore, the ability to confer with other specialists in the hospital greatly improves the level of care that we can provide to our patients. Surgical procedures are performed at our state-of-the-art facility, where the latest pain management techniques are performed and the safest anesthetic agents are used. All patients are attentively supervised throughout anesthesia and surgery.

Post-operatively, surgical patients recover in the intensive care unit, under the direct supervision of a compassionate staff of emergency clinicians, licensed veterinary technicians, and veterinary assistants. Our emergency department provides around-the-clock care to all of our hospitalized patients, 24-hours a day and 365 days a year.

Questions About Surgery

What does it mean to be a board-certified surgeon?
In order to promote surgical excellence for the profession, the American College of Veterinary Surgeons (ACVS) promotes advancements in veterinary surgery, and provides the most current surgical educational programs. The ACVS is enabling the veterinary profession to achieve its goals of providing outstanding service to the public and to animals by setting the highest standards in veterinary surgery. The ACVS Diplomate can be an aide to the primary care veterinarian by possessing the training, expertise and equipment to perform the most demanding procedures. Veterinarians who have successfully completed the certification requirements of the ACVS are Diplomates of the American College of Veterinary Surgeons and have earned the right to be called specialists in veterinary surgery. These requirements include: a degree in veterinary medicine from an American Veterinary Medical Association (AVMA) accredited program, completing a one-year rotating internship as well as a three year surgical residency program, and become published in a peer-reviewed journal.
What is the cost of specialty care?
The human-animal bond has become increasingly stronger over the past 20 years. Pet owners are willing to do as much as they possibly can to care for their animals, many times without regard to cost. OVRS in committed to ensuring that our pet owners understand the level of care and attention given to their pet. Much of the cost incurred goes towards 24-hour nursing care, 24-hour doctor availability, consistent post-operative monitoring of vitals during anesthetic recovery, implementation of pain management and pain control (i.e., injectable, oral, intra-dermal options), as well as towards the use of specialized equipment that helps ensure our high standard of care. OVRS is well-known for offering the type of veterinary care that is comparable to that available in human medicine.
How will my pet be monitored while under anesthesia?
Owners want to be assured that their pets are properly assessed during a surgical procedure. Here at OVRS, much of the monitoring equipment used in the OR is identical to that used in human hospitals. We are able to evaluate the patient's blood pressure, oxygen saturation, body temperature, carbon dioxide production, and ECG tracings. The most critical cases can also be monitored using direct blood pressure measurement, and blood gases can be obtained through an arterial catheter.
