Question 1

What is the primary purpose of the surgical 'time-out' procedure immediately before organ recovery surgery?

Accepted Answer

To verify donor identity, consent documentation, and planned recovery procedures

Answer

The surgical time-out is a universal safety protocol used to confirm donor identity, consent, and the intended procedure before incision.

Question 2

When multiple organs are procured from a single donor, which organs are typically recovered first?

Accepted Answer

Thoracic organs (heart and lungs) first, then abdominal organs

Answer

Thoracic organs are recovered first because the heart and lungs have the shortest tolerance for ischemia and must be transplanted most urgently.

Question 3

What is the optimal storage temperature range for organs during transport?

Accepted Answer

2–4°C (ice-slush range)

Answer

Organs are stored at 2–4°C in ice slush to significantly slow cellular metabolism and reduce ischemic damage without causing ice crystal injury from freezing.

Question 4

In organ procurement, what is the purpose of the 'flush-out' technique?

Accepted Answer

Infusing cold preservation solution through the organ's vasculature to remove blood and lower temperature

Answer

The flush-out delivers cold preservation solution through the vascular tree to displace blood, rapidly cool the organ, and begin preservation before removal.

Question 5

During abdominal organ procurement, which vessel is most commonly cannulated for in-situ flushing?

Accepted Answer

Aorta

Answer

The aorta is cannulated for in-situ flushing to deliver cold preservation solution to all abdominal organs simultaneously through their arterial supply.
