What is the primary purpose of the surgical 'time-out' procedure immediately before organ recovery surgery?
Answer: To verify donor identity, consent documentation, and planned recovery procedures
The surgical time-out is a universal safety protocol used to confirm donor identity, consent, and the intended procedure before incision.
When multiple organs are procured from a single donor, which organs are typically recovered first?
Answer: Thoracic organs (heart and lungs) first, then abdominal organs
Thoracic organs are recovered first because the heart and lungs have the shortest tolerance for ischemia and must be transplanted most urgently.
What is the optimal storage temperature range for organs during transport?
Answer: 2–4°C (ice-slush range)
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.
In organ procurement, what is the purpose of the 'flush-out' technique?
Answer: Infusing cold preservation solution through the organ's vasculature to remove blood and lower temperature
The flush-out delivers cold preservation solution through the vascular tree to displace blood, rapidly cool the organ, and begin preservation before removal.
During abdominal organ procurement, which vessel is most commonly cannulated for in-situ flushing?
Answer: Aorta
The aorta is cannulated for in-situ flushing to deliver cold preservation solution to all abdominal organs simultaneously through their arterial supply.
Why is 'warm ischemia time' considered the most damaging type of ischemia in organ procurement?
Answer: It is the period between circulatory arrest and organ cooling, when metabolic damage accumulates most rapidly
Warm ischemia time, from cessation of circulation to the start of cooling, causes the most rapid metabolic injury because cellular metabolism continues without oxygen delivery.
What is the standard packaging method for organs during transport to maintain both sterility and temperature?
Answer: Triple-bagged in sterile preservation solution, placed in ice in a transport cooler
Triple-bagging in sterile preservation solution with ice in a transport cooler provides layered sterility protection and maintains the required 2–4°C temperature range.
