Alternative Transfusion Options
Note: These
procedures require careful planning and cannot be carried
out for emergency operations at short notice. The procedure
may only be carried out on weekdays.
Autologous Donation
This option is an alternative to allogeneic
blood for those patients whose general condition falls within
donor guidelines and whose intraoperative blood requirements
can be reasonably accurately assessed.
Suitable candidates must be able to tolerate
the rapid withdrawal of 450~500ml of blood and the longer
term reduction in haemoglobin levels. They should be over
50kg in weight, have a haemoglobin level of 110g/l (hct
of 33%) or more and be between the age of 16 and 70. Older
or younger patients may be accepted after consultation with
the medical staff of the service.
Absolute contraindications to admission to
this program include severe heart disease, severe respiratory
disease, bacteraemia, insulin dependent diabetes and those
on anti-convulsive therapy.
The patient's doctor should initiate all requests
for this procedure and refer the patient to the Regional
Blood Transfusion Service. The procedure should be initiated
about six weeks prior to the operation depending on the
amount of blood needed.
Designated Donation
Another alternative to allogenic or Autologous
transfusion is the donation of the patient's blood requirements
by family or friends who have compatible blood groups. However,
in terms of voluntary self deferral safety, this carries
a risk of the exertion of undue pressure by the prospective
recipient.
It must be reiterated that this is not an
option in an emergency situation, as all blood must be fully
tested before issue. Blood from relatives carries the risks
of "graft versus host" disease and all blood from
such donors must be gamma irradiated before infusion.
All selected donors must conform to the
accepted voluntary donor criteria.
Designated donation procedures will only be
carried out on weekdays and within office hours.
NB: Because
of the stringency of the testing procedures and requirements
of irradiation at least 2 working days are required prior
to issue.
