What is Anemia?
Anemia is an absolute decrease in:
- RBC numbers
- hemoglobin concentration
- PCV
what is Acute Anaemia:
when about one-third of the blood volume is lost rapidly and not replaced. In acute blood loss, the animal usually shows the following features:
- tachycardia
- pale mucous membranes
- bounding or weak peripheral pulses
- hypotension
what is chronic anemia:
Anemia is associated as a result of chronic and inflammatory conditions. Prominent features include:
- lethargy
- weakness
- anorexia
- shortness of breath
- fast heartbeat
What is classification of Anemia?
1-Regenerative
In regenerative anemia, the response of bone marrow to the decreased red cell mass is appropriate and it increases the RBC production and releasing reticulocytes normally. Hemorrhage and hemolysis are examples of regenerative. Anemia.
Hemorrhage
It Maybe due to
- Trauma
- Surgery
- Occult (eg, GI blood loss).
- Coagulopathies.
- Bleeding tumors.
- Gastric ulceration.
- External or Internal parasites.
- bleeding from GI ulcers or tumors
Hemolytic Anemia
It Maybe due to
- immune mediated (60%–75%).
- Toxins.
- RBC trauma.
- Infections.
- Neoplasia.
- RBC membrane defects
2-Nonregenerative
In nonregenerative anemia, the response of bone marrow to the decreased red cell mass is inappropriate and the increased need for RBCs is not normal. Decreased erythropoietin and an abnormality in the bone marrow are examples of nonregenerative.
