b bloodstream while
would be in it. Instead they use a special blood substitute.
They have developed a method that is called an isolated aortic arch perfusion (SAAP).
In this case, through the femoral vein entered a special catheter, which is moving
to the aorta. He was then inflate and begin feeding oxygen-enriched
blood substitute, so he goes only to the upper body.
This makes it possible to take the patient to the operating room to stop bleeding and
ultimately save his life. Currently, cardiac arrest as a result of
massive bleeding, especially associated with blunt trauma, is characterized by
nearly 100 percent mortality.
While SAAP method using blood substitute HBOC-201, developed
by Biopure Corporation in Cambridge, which is based on hemoglobin and
can carry oxygen, has been tested on pigs. Animals simulated trauma
liver and waited for cardiac arrest resulting from loss of blood.
Six animals were SAAP with HBOC-201, the six control
pigs, this technique has been used in combination with saline. Spontaneous
restoration of cardiac activity was noted only in the first group.
According to the head of research, James Manning (James E. Manning),
require additional animal studies, after which it will be possible
proceed to clinical trials in humans.
