is·che·mi·a

 (ĭ-skē′mē-ə)
n.
A decrease in the blood supply to a bodily organ, tissue, or part caused by constriction or obstruction of the blood vessels.

[New Latin ischaemia, from Greek iskhaimos, a stopping of the blood : iskhein, to keep back; see segh- in Indo-European roots + haima, blood.]

i·sche′mic adj.

is•che•mi•a

(ɪˈski mi ə)

n.
local deficiency of blood supply produced by vasoconstriction or local obstacles to the arterial flow.
[1855–60; < Greek ísch(ein) to suppress, check + -emia]
is•che′mic, adj.

ischemia

Reduced blood supply to a part of the body or to an organ, especially the brain.

ischaemic stroke, ischemic stroke - the most common kind of stroke; caused by an interruption in the flow of blood to the brain (as from a clot blocking a blood vessel)
TIA, transient ischemic attack - brief episode in which the brain gets insufficient blood supply; symptoms depend on the site of the blockage

Other factors considered include ages of both donor and recipient and their comorbidities, donor characteristics that included warm and cold ischemia times (CIT)--the length of time the organ is perfused with a cold preservation solution until implantation and re-establishment of vascular flow, and the donor service area.
The graft was implanted with a cold ischemia time of 185 min.
Deceased donor transplants and lower recipient body mass index were found to be the biggest risk factors for postoperative SSH besides longer cold ischemia times.
They also found considerable geographic variation in the proportion of transplants that took place over the weekend: kidneys available for transplant over the weekend were more likely to be used at larger transplant centers, be shared without payback, and experienced shorter cold ischemia times.
Specifically, both warm and cold ischemia, with the accompanying reduction of blood flow, cause depletion of hepatocyte energy reserves, accumulation of intracellular sodium, calcium, and reactive oxygen species (ROS), and the activation of multiple enzyme systems leading to cell damage [8].
Total operative time was 390 minutes, the estimated blood loss was 400 cc and the total ischemia time was 79 minutes (4 minutes warm ischemia, 48mins cold ischemia, 27mins rewarming time) (Video at http://dx.
The blood is warmed to reduce the risk of cold ischemia injury - where the tissue dies because of a drop in temperature or lack of oxygen.
Cold ischemia occurs when tissues or organs within or removed from the human body are allowed to cool before being preserved.
The cold ischemia time is the time from ligation of the last vessel in the organ/tissue to the time in which the sample is put in fixative/frozen.
New research shows that broader sharing of deceased donor livers will not significantly increase cold ischemia time (CIT)-the time the liver is in a cooled state outside the donor suggesting that this is not a barrier to broader sharing of organs.
The upper limit of ischemia times for major injuries from the level of shoulder to the wrist are 6 hours of warm and 12 hours of cold ischemia, although occasionally success has been reported after longer ischemia times.
