Summary of the Video "DIP abordaje Anemia 1"

Main Ideas and Concepts:

• Understanding Anemia in Dogs:

  Anemia is characterized by a decrease in red blood cells, leading to clinical signs such as lethargy, anorexia, pica (eating non-food items), decreased activity, and potential weight loss. Symptoms manifest primarily when Anemia is severe (red blood cell levels below 15%).

• Clinical Manifestations:

  Common signs of severe Anemia include:

  • Lethargy
  • Anorexia
  • Pica (interest in eating inappropriate substances)
  • Decreased activity
  • Weight loss

  Mild Anemia (15-25% red blood cell count) may result in mild exercise intolerance, while levels above 25% are often asymptomatic.

• Oxygen Delivery and Anemia:

  The primary consequence of Anemia is hypoxia (lack of oxygen) due to reduced oxygen transport capacity. Oxygen delivery depends on cardiac output and the amount of hemoglobin in the blood.

• Classification of Anemia:

  Anemia is not a diagnosis but a clinical abnormality; the underlying cause must be identified. Classifications include:

  • Severity: mild, severe, very severe
  • Regenerative vs. non-regenerative based on reticulocyte counts.
  • Morphological characteristics: microcytic, normocytic, macrocytic, hypochromic, normochromic, hyperchromic.
• Diagnostic Approach:

  A systematic approach is necessary for diagnosing Anemia:

  • Evaluate clinical history and exposure to drugs/toxins.
  • Conduct Blood Tests to assess red blood cell counts and reticulocyte levels.
  • Consider further tests (Bone Marrow Aspirate, imaging) if initial tests do not identify the cause.

  Anemia in older Dogs (over 8 years) is common, with various potential underlying causes including hormonal conditions, neoplasia, infections, and organ failures.

• Importance of Reticulocyte Response:

  The Reticulocyte Count is crucial in determining whether Anemia is regenerative (indicating a response to blood loss or hemolysis) or non-regenerative. A Reticulocyte Count of over 60,000 per microliter indicates regeneration.

• Patterns of Anemia:

  Different patterns can be identified through mean corpuscular volume (MCV) and mean corpuscular hemoglobin concentration (MCHC) tests, which help classify the type of Anemia.

Methodology for Diagnosing Anemia:

• Initial Assessment:
  • Review clinical history, including drug exposure.
  • Perform a Complete Blood Count (CBC) to evaluate red blood cell levels.
• Classification of Anemia:
  • Determine severity (mild, severe, very severe).
  • Assess reticulocyte response to classify as regenerative or non-regenerative.
• Further Testing:

  If red blood cell levels are below 30%:

  • Check for other cytopenias (thrombocytopenia, neutropenia).
  • Consider infectious diseases, especially in older Dogs.
  • Conduct biochemical profiles, urine tests, and imaging studies.

  If no cause is identified, a Bone Marrow Aspirate may be necessary.
