Anaesthesia · Cardiovascular physiology, fluids, and blood management: curriculum recognition

Sample item

A bedside whole-blood test traces clot initiation, clot strength and clot breakdown in real time and helps to guide product replacement in a bleeding patient. What is it called?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Viscoelastic testing (TEG or ROTEM)

Viscoelastic tests give a dynamic picture of the whole clotting process and show whether the problem is factor deficiency, low fibrinogen, poor platelet function or hyperfibrinolysis. Conventional laboratory tests take longer and examine only parts of the process.

Option by option

  • A. Bleeding time

    Bleeding time is a crude test of platelet function and does not trace clot strength.

  • B. Activated clotting time

    The activated clotting time measures only the time to clot, used to monitor heparin.

  • C. Platelet count

    A platelet count gives numbers only and says nothing about clot function or fibrinolysis.

  • D. Viscoelastic testing (TEG or ROTEM) (correct)

    Correct. Thromboelastography and thromboelastometry trace the whole clot in real time.
