Course Information:
This course will cover the key concepts regarding point of care ultrasound (POCUS). POCUS techniques are rapid, easy-to-learn and practical ultrasound skills that ANY practitioner can apply in everyday practice. This co-lecture series by a criticalist and an internist will cover the core principles to understand and interpret sonographic findings of abdominal POCUS including the identification of free fluid, urine production, GI motility, free abdominal air and the gall bladder halo sign. The core principles to understand and interpret sonographic findings of the pleural space and lung. The principles of cardiac anatomy with an emphasis on the key cardiac windows to assess (there are 3 that answer most clinically relevant questions), being able to confidently identify pericardial effusion, cardiac volume status, pulmonary hypertension, and how to differentiate these conditions from common cardiomyopathies will be presented. All clinically relevant questions when asked at the right time, in a binary fashion, based on patient assessment! Covering all things that can be used by general practitioners in everyday practice. If you own an ultrasound machine, there is no excuse to not apply these principles on a daily basis!

  • explain the difference and be able to identify wet lung vs dry lung using ultrasound.
  • describe the pathophysiology of why lung consolidation can be seen with POCUS.
  • describe how pleural irregularities can help differentiate causes of wet lung.
  • explain how to differentiate partial lung consolidation from trans-lobar consolidation.
  • describe the most common types of consolidation and how to differentiate them: shred, trans-lobar hepatization, nodule and thromboembolism.
  • explain how the sonographic characteristics of lung consolidation can be interpreted to help differentiate simple atelectasis from pathologic consolidation (static vs. dynamic air bronchograms and fluid bronchograms).

  • describe where to assess fluid responsiveness using POCUS.
  • explain how the caudal vena cava is used to estimate intravascular volume status.
  • describe the difference between in plane and out of plane ultrasound guided vascular access.
  • tie together cardiac POCUS, lung ultrasound, and vascular POCUS to estimate and differentiate hypovolemia from volume overload.

Level and Prerequisites: This basic VIN CE course is open for enrollment to veterinarians actively interested in veterinary Point of Care ultrasound.
RACE Accreditation: This course is approved for 7 hours of continuing education credit by RACE for veterinarians. (RACE 20-810782)

Course Agenda:

Week 1 (Real Time Session April 1, 2021): Ultrasound definitions, evolution, and the binary approach to learning!
Please note this session is only 1 hour long: 8:00-9:00 pm ET. All other sessions will be 2 hours long: 8:00-10:00 pm ET. This first session will cover POCUS techniques including common definitions and evolution of the field, how POCUS differs from consultative ultrasound exams, the key formats currently used, when and where POCUS should be applied, patient positioning, coupling agents, and the value of using clinically relevant binary questions.

Week 2 (Real Time Session April 8, 2021): Abdominal Ultrasound
Ever wonder if the cat that ate lilies is producing urine when it's not possible to pass a urinary catheter? Ever wonder if the dog with an acute abdomen has free abdominal air in the abdomen, or if the post-operative patient that is not eating has ileus? Using a binary approach to ask the right question at the right time makes learning and applying abdominal point of care ultrasound easy!

Week 3 (Real Time Session April 15, 2021): Pleural Space and Lung Ultrasound
Ever struggle with determining the cause of dyspnea in a cat that is too unstable to take radiographs or draw blood for ProBNP levels (cardiac, respiratory, pleural effusion)? Ever debate if you should discontinue IV fluids in the patient with mild tachypnea? Have you ever felt frustration at not finding a cause for patients presenting for “ain’t doing right” with no specific clinical signs? Veterinary point of care ultrasound (POCUS) can help you manage these patients! Following a binary approach, the key principles of the bat sign, gator sign, glide sign, A lines, B lines, lung pulse, and curtain sign, dry lung and wet lung will all be covered.

Recent veterinary studies have demonstrated the agreement between some veterinary thoracic and lung ultrasound protocols and CT scans are less than ideal when it comes to diagnosing pleural effusion and pneumothorax, and to some extent, lung pathology. This should not be the case! This session will focus on a practical approach to point of care ultrasound that considers clinical findings and challenges current protocols by asking the question; “where will pathology accumulate” and subsequently, “what should we be sonographically looking for to answer binary, relevant, rapid, clinical, and often lifesaving questions”. Don’t simply put the probe on the patient or expect a “one protocol fits all” approach to be applicable to all situations; ask the right question and know how to modify protocols to increase the chance of success with pleural space and lung pathology!

Lung ultrasound has significantly evolved over the past two decades and knowing how the identification of artifact at the surface of aerated lung can progress to consolidated lung when the ratio of aerated to non-aerated lung falls below 5-10% is key to identifying lung pathology beyond simple wet lung. Lung consolidation is not difficult to identify and knowing how consolidations differ with regards to their borders and the characteristics seen within lung consolidations, along with history and other clinical findings allows the differential diagnosis to be narrowed.

Week 4 (Real Time Session April 22, 2021): Cardiac and Vascular Ultrasound
Ever struggle with deciding if the dyspneic cat or dog should receive furosemide for possible congestive heart failure or wonder if maybe steroid administration for feline asthma would be more appropriate? What about differentiating pericardial effusion from dilated cardiomyopathy on thoracic radiographs, or trying to decide if that fluid seen on ultrasound is pleural or pericardial? What about differentiating pseudohypertrophy and hypovolemia from hypertrophic cardiomyopathy in the cat? This session will build on each prior lecture and continue the binary approach to answering clinically relevant and appropriate questions to ask. The best part of POCUS is that you do not have to be a cardiologist or radiologist to perform these techniques!

A patient presents collapsed, it has poor pulses and a prolonged capillary refill time – it is in cardiovascular shock! (The internist runs away). Should an IV fluid bolus be given, and if so, how much and how will the patient likely respond to IV fluid therapy (The criticalist is super excited)? Where and how can you look at the vascular system to estimate intravenous volume status and fluid responsiveness? What is a flat vs. fat vena cava tell you? One last question: have you ever struggled to place an IV catheter in a patient that is dehydrated, has hematomas, thick skin or edema? You guessed it, ultrasound can help, and we will show you how!
