CTP Organ Recovery & Procurement Logistics 2

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

To allow the surgical team to rest before a lengthy procedure

Answer

To confirm that preservation equipment is functioning

Answer

To calculate expected total ischemia time

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

Kidneys first, then liver, then heart

Answer

Abdominal organs first, then thoracic organs

Answer

All organs are removed simultaneously by separate teams

Question 3

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

Accepted Answer

2–4°C (ice-slush range)

Answer

0–2°C

Answer

10–15°C

Answer

20–25°C (room temperature)

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

Rinsing surgical instruments before the procedure

Answer

Cleaning the donor's body cavity after recovery

Answer

Testing organ function after removal

Question 5

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

Accepted Answer

Aorta

Answer

Superior vena cava

Answer

Pulmonary artery

Answer

Portal vein exclusively

Question 6

Why is 'warm ischemia time' considered the most damaging type of ischemia in organ procurement?

Accepted Answer

It is the period between circulatory arrest and organ cooling, when metabolic damage accumulates most rapidly

Answer

It refers to time spent above freezing but below body temperature

Answer

It describes time spent in normothermic machine perfusion

Answer

It measures time at room temperature during packaging

Question 7

What is the standard packaging method for organs during transport to maintain both sterility and temperature?

Accepted Answer

Triple-bagged in sterile preservation solution, placed in ice in a transport cooler

Answer

Single sterile bag placed in a foam cooler

Answer

Vacuum-sealed plastic wrap in a refrigerated case

Answer

Single bag immersed in warm saline in an insulated container
