(35 cards)
Treatment for rodenticide toxicity
Fluids
Oxygen
Make vomit if early
Blood FFP FWB RBC
What are some coagulation tests?
Platelet count BMBT aPTT PT ACT Biochem panel TT
What is the cause of IMHA
Anemia from destruction of RBC by antibodies
What do you need for platelet count?
What is normal count ?
- EDTA rube
- smear
10-15 platelets PHF is normal
What is the causes of thrombocytopenia 1-3
-1- platelet destruction
2- platelet consumption
3- lowered platelet production
Cause of rodenticide toxicity
Lack of activation for vit k and clotting factors
Cause of Von willebrand disease
Lack of vWF in blood
What is a platelet and it’s function ?
Thrombocyte
Plug holes in damaged vessels to prevent bleeding
Treatment of VWD
Blood products
- FFP
- RBC
- Cryo
- Desmopressin acetate
Signs of clotting/ bleeding disorder
Petechia Melena Haematoma Hematuria Anaemia Bleeding in a few sites
What are the 3 stages of haemostasis
1- vasoconstriction
2- primary haemostasis
3- secound art haemostasis
What is anaemia ?
Reduced RBC
What diagnostics can be used for IMHA
PCV
Blood smear
Haematology
What is primary and secondary coagulation
Primary- platelets
Secondary- coagulation factors
Nursing care for blood disorders
NO JUGULAR Small needle Pressure on sites Min walking/ bubble wrap Monitor pcv and platelet count Min blood sampling
Treatment for IMHA primary and secondary
Primary- immunosuppressive drugs
Secondary- find cause
Technique for sampling coagulation includes:
- clean venipuncture, new needle each time. If disturbed coagulation occurs, leave and try again if it does.
- no jugular !
- anticoagulant tine eg EDTA, citrate
- send ASAP
Diagnostics for VWD
Bmbt
vWF levels testing
What is haemostasis
The prevention of blood loss by sealing sites of injury
What are clotting factors ?
Other substances in plasma
How to diagnose thrombocytopenia
Blood smear with platelet count
Bone marrow biopsy
Treatment for thrombocytopenia
- immunosuppressive drugs to stop platelet destruction
- blood products to give platelets. FFP, FWB,PRP
- stop bone marrow from producing too many via chemo, antibiotics
Where do platelets come from
Bone marrow
What are the three causes for Thrombocytopenia
1- platelet destruction
2- platelet consumption
3- low platelet production
