The United
Network for Organ Sharing, which coordinates the distribution
of cadaver organs in the United States, reports that the use of
a three-drug combination after brain-death in all U.S. donors
could enable retrieval of more than 2,300 additional organs a
year for transplantation.
Researchers
reported at the American transplant scientific meeting that they
examined records for all brain-dead organ donors from January
2000 to June 2001, and found that hormonal resuscitation drugs
had been used to better preserve organs in 584 donors, but had
not been used in 8,185.
They said
that doctors retrieved an average of 3.8 organs from donors who
had received the drugs, and an average of 3.1 organs from donors
who had not.
The drug combination,
which includes a hydrocortisone bolus and infusions of vasopressin
and tri-iodothyronine, is administered after patients have been
declared brain dead -- and their families have agreed to donation
-- to better preserve the donor's organs until they can be removed.
Each donor
is theoretically able to contribute two kidneys, a pancreas, two
lungs, a heart, a liver and intestines, although a variety of
considerations -- including age of donor and condition of organs
-- make it relatively unusal for doctors to retrieve more than
four from one donor.
But UNOS researchers
suggested that if the average for all donors could be raised to
the 3.8 level, the higher rate would have produced 924 more kidneys,
278 hearts, 290 livers, 414 lungs and 456 pancreases for patients
on the growing transplant waiting lists.
"There's
no reason why it couldn't be used theoretically on every donor,"
said Dr. H. Myron Kauffman, a UNOS consultant.. "We hope
by getting the message out with this presentation that it will
be used more widely."
