Emergency Critical Care

Clinical trials for Emergency Critical Care specialty

  • Status:  Currently enrolling


    The success of cardiopulmonary resuscitation (CPR) is very low, in veterinary (as well as human) patients. Even after successful return to spontaneous circulation, sequela to CPR include repeated cardiac arrest, brain disease, and multi-organ system failure. Low oxygen levels to the brain is the major factor contributing to these poor outcomes. There is a critical gap in our understanding of the physiology and prognosis after CPR, which has led to failure to substantially improve our success in dealing with this problem.

    An important goal of this study is to understand how chemicals called nucleic acids (RNA) are altered in post-CPR canine patients. The study will focus on very small RNA (miRNA). The specific objective of this study is to understand which miRNA are released into the circulation of canine patients after cardiopulmonary resuscitation (CPR) versus non-CPR patients hospitalized in the ICU for other reasons.

    There is tremendous potential value in identifying circulating miRNA after CPR. First, miRNA may assist in predicting outcome (prognosticating) in individual patients in the future. Second, miRNAreleased into the circulation are indicators of major epigenetic disturbances as a consequence of hypoxia-ischemia.    Knowledge of these miRNA may lead to the design of novel therapies to counteract these effects, for example employing stem cells that release mitigating miRNA.

    Inclusion Criteria:

    Group 1:  Six dogs that have undergone CPR according to standard protocols in the TCSVM emergency room and have returned to spontaneous circulation for a minimum of 1 hr.

    Group 2:  Six dogs hospitalized in the ICU that have not experienced CPR or significant hypoxemia or ischemia (e.g. GDV, hemorrhage, stroke) will be selected for sampling at the same time (AM vs. PM). Dogs will be similar age and gender as post-CPR patient.

    Any breed is acceptable.

    Exclusion Criteria:

    • Dogs < 10 kg
    • Dogs with prior hypoxemia insult (prior arrest or CPR, GDV, stroke, hemorrhagic shock, congestive heart failure, etc).
    • Dogs with a diagnosis of cancer
    • Dogs with hemolytic disease
    • Dogs for which blood sampling is contraindicated (recent fluid/colloid resuscitation)


    Client Benefits:

    The study will cover the cost of a blood panel (NOVA) at the same time the sample is being collected; this is testing that is normally performed every few hours during recovery from CPR, it is also testing that is normally performed in sick dogs. Your pet’s participation will also allow us to gain information which will help in the treatment of other dogs with this condition. You understand that your animal’s participation in this study may not alleviate or cure his/her ailment

  • IACUC protocol #: G2017-28

    Status:  Currently enrolling


    Immune-mediated hemolytic anemia (IMHA) is an important disease in dogs that causes anemia (a low red blood cell count). We would like to be able to identify how a patient is responding to therapy using a blood test.  We hope to identify how long it takes to see suppression of the immune markers in a blood sample during therapy and see if this varies by treatment regimen used.  We will be looking at three different  lymphocyte responses during treatment for IMHA. Our goal is to identify if one of these markers decreases more rapidly in response to immunosuppressive treatment, and if one treatment is best associated with patient survival at 1 month.

    Inclusion Criteria:

    Dogs diagnosed with immune-mediated hemolytic anemia weighing more than 6 kg.

    Client Benefits:

    As part of the study, you will receive a free 2 and 4 week recheck with our Internal Medicine service. Cost of the blood draw will be covered by the study, as will the cost of the recheck red blood cell test (PCV).
