haematology and haemostasis clinical cases Flashcards
based on the following hematology results, which values indicate anemia
- HCT (gives proportion of RBCs in the blood)
- RBC (give you the total number of RBCs)
- Hgb
based on the hematology results below, which values are used to characterize anemia
- reticulocytes (indicates if new erythrocytes are being produced in the bone marrow)
- MCHC (indicates size level of hemoglobin per RBC)
- MCV (indicates the size of the RBCs)
based on the hematlogy results below, characterize felix’s anemia
- normocytic (normal MCV)
- normochromic (normal MCHC)
- non-regenerative (reticulocyte count in normal range)
how does kidney disease lead to anemai
erythropoietin is produced in the kidney, kidney diseases reduces EPO and therefore the bone marrow cant produce more erythrocytes
feliix’s blood type is determined to be blood group B. what blood group is suitable for donation to felix
B. blood group B cats carry high levels of anti-A antibodies that would lead to the destruction of RBCs from cats of blood group A or AB resulting in a strong transfusion reaction
Felix’s current PCV is 10% and we want to raise it to 20%. he weighs 3.5 kg. how much blood do you need
volume = desired PCV rise (%) x bodyweight(kg)x2
=70 ml
freddie, who is blood type B is deemed a suitable donor for Felix (also blood type B)
he weighs 8 kg. can the amount of blood needed for felix (70 ml) be safely collected from freddie
yes
a cat has approx. 66 ml blood/kg and it is safe to collect 10-20% of TBV
66x8x0.2 = 105 which exceeds the amount freddie needs.
