CCTC Organ Procurement and Preservation

Question 1

What is the primary purpose of hypothermic preservation in organ procurement?

Accepted Answer

To slow cellular metabolism and extend organ viability

Answer

Hypothermic preservation slows metabolic activity, reducing oxygen consumption and extending the time organs can remain viable before transplantation.

Question 2

Which preservation solution is most commonly used for kidney procurement in the United States?

Accepted Answer

University of Wisconsin (UW) solution

Answer

UW solution is the gold standard for kidney preservation because it prevents cellular swelling, oxidative injury, and ATP depletion during cold storage.

Question 3

What does DCD stand for in the context of organ donation?

Accepted Answer

Donation after Cardiac Death

Answer

DCD (Donation after Cardiac Death) refers to organ procurement following irreversible cessation of circulatory and respiratory functions.

Question 4

Which organ has the shortest acceptable total ischemia time due to its extreme sensitivity?

Accepted Answer

Heart

Answer

The heart is extremely sensitive to ischemia and has the shortest acceptable cold ischemia time, generally limited to 4–6 hours from cross-clamp to reperfusion.

Question 5

What is the primary role of an Organ Procurement Organization (OPO) in the transplantation process?

Accepted Answer

Coordinating organ recovery, preservation, and allocation

Answer

OPOs identify potential donors, coordinate consent, manage organ recovery and preservation, and facilitate allocation through UNOS/OPTN.
