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

Sample item

During repair of a ruptured aortic aneurysm, blood is aspirated from the operative field, anticoagulated, centrifuged, washed and returned to the patient. Which technique is this?

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

The answer and the reasoning

A. Intraoperative cell salvage

Cell salvage collects shed blood, washes the red cells and reinfuses them, which suits operations with large expected blood loss. Haemodilution instead withdraws blood before surgery, and autologous donation stores blood in advance.

Option by option

  • A. Intraoperative cell salvage (correct)

    Correct. Shed blood is collected, washed and reinfused during the operation.

  • B. Preoperative autologous donation

    Preoperative donation collects and stores blood weeks before surgery.

  • C. Directed donation from relatives

    Directed donation uses blood from chosen donors, not the patient's own shed blood.

  • D. Acute normovolaemic haemodilution

    Haemodilution removes blood before bleeding starts and replaces it with fluid.
