haematology and haemostasis clinical cases

Question 1

based on the following hematology results, which values indicate anemia

Answer 1

• HCT (gives proportion of RBCs in the blood)
• RBC (give you the total number of RBCs)
• Hgb

Question 2

based on the hematology results below, which values are used to characterize anemia

Answer 2

• 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)

Question 3

based on the hematlogy results below, characterize felix’s anemia

Answer 3

• normocytic (normal MCV)
• normochromic (normal MCHC)
• non-regenerative (reticulocyte count in normal range)

Question 4

how does kidney disease lead to anemai

Answer 4

erythropoietin is produced in the kidney, kidney diseases reduces EPO and therefore the bone marrow cant produce more erythrocytes

Question 5

feliix’s blood type is determined to be blood group B. what blood group is suitable for donation to felix

Answer 5

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

Question 6

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

Answer 6

volume = desired PCV rise (%) x bodyweight(kg)x2
=70 ml

Question 7

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

Answer 7

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.
