Question

Warm ischemic time for vascular tissue is defined as:

a. The time interval from subjecting cardiac tissue to cold rinse or transport solution at retrieval to the beginning of disinfection
b. The time interval from subjecting vascular tissue to transport solution and wet ice temp at retrieval to the beginning of disinfection
c. The time interval asystole to subjecting cardiac tissue to cold rinse or transport solution at retrieval
d. The time interval from asystole to subjecting vascular tissue to transport solution and wet ice temp at retrieval

Answer 1

b. The time interval from subjecting vascular tissue to transport solution and wet ice temp at retrieval to the beginning of disinfection Warm ischemic time for vascular tissue refers to the period from asystole to the point when the tissue is subjected to transport solution and wet ice at retrieval, which is best described by definition 'd'.

Step-by-step explanation:

The warm ischemic time for vascular tissue is the period from asystole, which is the cessation of the heartbeat, to when the vascular tissue is subjected to a transport solution and placed on wet ice at retrieval. This encompasses the time when the tissue is still at body temperature and not yet being preserved at lowered temperatures. It's a critical period because during this time the tissue is deprived of oxygen and nutrients, which can cause damage.

The correct definition in this context would relate to the time from asystole to preservation efforts, aligning with option 'd.' In organ transplantation, particularly heart transplantation, minimizing this warm ischemic time is crucial to maintaining the viability of the organ for the recipient.Warm ischemic time for vascular tissue is defined as the time interval from subjecting vascular tissue to transport solution and wet ice temperature at retrieval to the beginning of disinfection.
