70
There is no risk of disease
transmission, transfusion
reactions, or alloimmunization to
white blood cells, RBCs, platelets, or plasma proteins.
AUTOLOGOUS DONATION
71
former tag for Autologous units
distinct green label and tag
72
There are four different types of autologous donation:
o Preoperative collection
o Acute normovolemic hemodilution
o Intraoperative collection
o Postoperative collection
73
include patients
undergoing orthopedic procedures, vascular surgery,
cardiac or thoracic surgery, and radical prostatectomy.
PREOPERATIVE COLLECTION
74
No deferral of the donor-patient except
when there is a risk
of bacteremia
75
involves removal of whole
blood from a patient with infusions of crystalloid or
colloid before surgical blood loss.
ACUTE NORMOVOLEMIC HEMODILUTION
76
These can be also use as blood substitute
crystalloid or
colloid
77
involves collecting and
reinfusing blood lost by a patient during surgery.
INTRAOPERATIVE COLLECTION
78
prone for bacteremia
INTRAOPERATIVE COLLECTION
79
INTRAOPERATIVE COLLECTION has been used in
cardiothoracic,
major orthopedic, and cardiac surgery and vascular
surgeries such as liver transplantation.
80
a unit collected under the same
requirements as those for
allogeneic donors
DIRECTED DONORS
80
Blood is collected from a drainage tube placed at the
surgical site.

example of moderate reaction
loss of consciousness
Decreased pulse rate, hyperventilation, fall in systolic pressure to 60mmHg.
105
