She completed veterinary school and earned a master's degree in veterinary pathology at Kansas State University.

Point of Care Assessment of Coagulation

Abstract: Disorders of hemostasis can be difficult to fully elucidate but can severely affect patient outcome. The optimal therapy for coagulopathies is also not always clear. Point of care (POC) testing in veterinary medicine can assist in the diagnosis of hemostatic disorders and also direct treatment. Advantages of POC testing include rapid turnaround times, ease of use, and proximity to the patient. Disadvantages include differences in analytic performance compared with reference laboratory devices, the potential for operator error, and limited test options per device. Conventional coagulation tests such as prothrombin time, activated partial thromboplastin time, and activated clotting time can be measured by POC devices and can accurately diagnose hypocoagulability, but they cannot detect hypercoagulability or disorders of fibrinolysis. Viscoelastic POC coagulation testing more accurately evaluates in vivo coagulation, and can detect hypocoagulability, hypercoagulability, and alterations in fibrinolysis. POC platelet function testing methodologies can detect platelet adhesion abnormalities including von Willebrand disease, and can be used to monitor the efficacy of antiplatelet drugs. It is unlikely that a single test would be ideal for assessing the complete coagulation status of all patients; therefore, the ideal combination of tests for a specific patient needs to be determined based on an understanding of the underlying disease, and protocols must be standardized to minimize interoperator and interinstitutional variability.

Emergency & Critical Care

Our Critical Care Service excels in managing patients recovering from major surgery, illness, or trauma and those patients requiring positive pressure ventilation or other specialized care. Our critical care team includes three board-certified critical care specialists, Dr. Valerie Madden, Dr. Clare Hyatt and Dr. Laura Osborne, and resident Dr. James Lange. Your pet will get the best care possible. 

Our Emergency Service is staffed by a team of highly skilled veterinarians and technicians who are equipped and prepared to handle any pet emergency with skill, speed, and compassion. We have the ability to offer all levels of care in an emergency and are outfitted to care for even the most critical patients. One or more veterinarians and technicians are on-site at all times.

Our team will work closely with your family veterinarian to make sure your pet gets the best care possible before, during, and after hospitalization. Open communication with your family veterinarian during regular business hours, and the transfer of medical records and test results by fax or email, allows us to keep your veterinarian informed of your pet's progress.

Our dedicated intensive care unit (ICU) is equipped to provide oxygen therapy, cardiac monitoring, blood transfusions, mechanical ventilation and nutritional support. Our in-house laboratory, radiology and ultrasound capabilities enable us to get crucial diagnostic information very quickly. Our blood bank allows our canine and feline patients to have access to a safe blood supply.

Triage/Waiting Times:

No appointment is ever necessary to see the emergency service. We are here when your pet is ill.

Our hospital works on the same triage principle as human hospitals where the more seriously ill or injured patients will be seen before stable and healthy patients. If necessary, seriously ill or injured patients may be moved straight to our treatment room for immediate assessment by an emergency veterinarian. This allows us to provide your pet with life-saving medications and treatments in a timely and efficient manner.

Financial Policy:

We promise to stay transparent with our costs. All patients will be charged an emergency consultation fee. This fee covers the initial evaluation and assessment by a veterinarian to help make the best recommendations for you and your pet. We will provide detailed financial estimates for all treatment options so that you can decide on the best course of action for your family and pet.

Our fees ensure that we can provide the highest quality veterinary care with a modern, fully equipped medical facility, and provide a board-certified and specialty-trained team to care for your pet.
