All You Need to Know About Emergency Medicine & Toxicology
November 20, 2018
Dr. Justine Lee
Does seeing an emergency case make you tachycardiac? Not sure how to tap a chest of a dyspneic cat? Not sure how to induce vomiting in that fractious cat? Join us for a review of emergency medicine and toxicology with Dr. Justine Lee, DVM, DACVECC, DABT. In this session, Dr. Lee will review common mistakes to avoid in the emergency patient and the poisoned patient, including when to reach for steroids, when to use the “shock dose” of intravenous fluids, and when to induce emesis. She’ll also review what emetic agents to use, the contraindications for using activated charcoal, along with how to perform common emergency procedures (such as thoracocentesis, gastric lavage, pericardiocentesis). If you don’t see emergency patients every day, or if you need a review of emergency medicine and toxicology, join us for some clinically relevant, practice learning!

Everything You Need to Know About Immune Mediated Diseases: IMHA, ITP, NIRMA

Dr. Jennifer Kyes
Mississauga Oakville Veterinary Emergency Hospital
There are 3 conditions that plague veterinary medicine that will be discussed in this lecture; immune mediated hemolytic anemia (IMHA), immune mediated thrombocytopenia (IMTP) and nonregenerative anemias (NRA).
There are several characteristics common to cases with IMHA making it a relatively simple diagnosis. Presenting signs are often lethargy, anorexia, collapse, pale gums, or changes in colour to their pet’s urine or stool. It is important to convey the prognosis and estimated cost to the owner at the time of diagnosis. Mortality rates can be as high as 50% in the first 3 weeks and there is a 50% chance that a relapse occurs in the future.
Any patient with a confirmed platelet count of <20,000 x109 and the absence of a underlying cause should be consider to have IMTP. The most common clinical sign is petechia and ecchymosis but additional signs include melena, gingival bleeding, hematoma formation, pale gums, bleeding into the eye, vomiting blood, nose bleeds, and bloody urine. Short-term survival rates are better for IMTP and report at 74-97% with recurrence rates up to 50%.
One classic feature is that these patients are surprisingly bright and alert for the severity of anemia making this condition chronic and well compensated unlike IMHA and ITP. Clinical signs include lethargy, weakness, weight loss, collapse, exercise intolerance, vomiting, fever and syncope.
