Haematology for Clinical Finals

Paul Greaves: Consultant Haematologist, BHRUT, Romford

21 cases, 88 MCQs, and a framework to guide your cramming

The whole of haematology in 2 hours...In 21 cases, 88 MCQs and a framework to hang your cramming on...

Haematology is 5 things:

1. Clotting2. Transfusion3. Cancer4. Red cell5. Dire emergencies you must never mess up

CLOTTING is 5 things

1. PT, APTT and two ways to make a clot2. How to use heparin, warfarin and NOACs3. What to do with a bleeding patient taking anticoags4. Bleeding tendency5. Clotting tendency

TRANSFUSION is 5 things

1. Red cells: ABO, Rh and K2. Plasma3. Platelets (and thrombocytopenia)4. Tranexamic Acid5. Cryo, Fibrinogen, The stuff in a locked cupboard

➢ octaplex, novoseven, factor concentrates

CANCER (Leukaemia, Lymphoma, Myeloma, MPD) is 5 things1. Presentation

➢ lumps, organomegaly, bone marrow failure, infection

2. Diagnostics ➢ scans, bone marrow, biopsy, blood film, flow, cytogenetics

3. Treatment ➢ chemo, radio, targeted antibodies, targeted molecules

4. Supportive care➢ antiemetics, mouth-care, antimicrobials, bisphosphonates,

psychosocial

5. Emergencies➢ sepsis, tumour lysis, leukostasis, cord compression

RED CELL is 5 things

1. Haematinics2. Haemoglobin/opathy3. Haemolysis4. Haemochromatosis5.

5 things to NEVER MESS UP

1. Massive Transfusion and transfusion reactions2. Sepsis, Tumour Lysis & Hypercalcemia3. Cord Compression4. Sickle Chest crisis5. Dangerous thrombocytopenias

Never MissTumour lysis syndrome: Hyperphos, hypocalc, Oliguria

Prevent with allopurinol, rasburicase and generous IV fluidsCord Compression: Back pain, known malignancy (or suspected), neurology

Suspect with low index of suspicionSteroids (unless a new diagnosis), image, radiotherapy, neurosurgery

Thrombotic Thrombocytopenic PurpuraAnaemia, jaundice, thrombocytopenia, fever, renal fx, NeurologicalIV lines and straight to pheresis centre for PLEX +/- chemotherapy

Acute transfusion reactionUnwell on a transfusion -> STOP it, ?adrenaline neededcheck BAG, BAND, BLOOD; involve HDU, Hydrate, inform lab, send samples,

Never Miss: the dangerous thrombocytopeniasAlways ask for a blood film and check medication historyAre they bleeding? Or may they have a clot?Could they have a bone marrow failure or immunological syndrome?� Pregnancy-Associated

○ Liver function? Proteinuria? Hypertension?○ Think HELLP / Eclampsia spectrum

� Heparin Induced Thrombocytopenia & Thrombosis (HITT)� Thrombotic Thrombocytopenic Purpura (TTP)

○ Anaemia, jaundice, thrombocytopenia, fever, renal fx, Neurological○ IV lines and straight to pheresis centre for PLEX +/- chemotherapy
